No additional repairs were required at this time, but routine servicing and testing are key to maintaining a safe and healthy indoor environment.

In this Newtown home, built in the 1970s, elevated radon levels led to a thoughtful discussion between the installer and homeowners, Todd and Melinda. Rather than jumping into a multi-system setup, both parties agreed to install a single-pipe mitigation system first, and monitor the results using a CRM or passive test kit. If the levels remain above 2.0 pCi/L, a second system will be installed without delay. This agreement was clearly communicated and documented to ensure alignment between both the service provider and the client.

The install itself was straightforward but executed with precision. The system was routed internally with minimal disruption to the home structure. The radon fan, piping, and exhaust layout were positioned based on airflow mapping and best practices. The job did not require extra sump pump sealing or encapsulation. The installer made sure to place a test kit before leaving the site and ensured the homeowners were comfortable monitoring and returning results. Overall, this job is a prime example of responsive radon mitigation built around both trust and measurable results.

This project in New Canaan, CT began with a phone consultation from Adrian Dognin, the general contractor managing the renovation of the home. According to Adrian, one part of the house has already been taken down to the studs, while the other part of the home remains, and it contains a crawlspace underneath. He noted that the radon levels are elevated, although the exact pCi/L was not provided, and he suspects the crawlspace was not included in the original radon testing.

The homeowner, Lynne, is preparing to sell the home but currently has no firm closing date. Either Adrian or Lynne will be present during the on-site consultation. During the visit, be sure to get Lynne’s contact details and update the client record to reflect her information directly.

The next step will include visual inspection, possible re-testing (especially in the crawlspace), and mapping out potential system design(s) that may include both slab and crawlspace mitigation strategies, depending on confirmed radon levels and structural access.

This Westport job was coordinated entirely remotely with the seller, who will not be present during the fan replacement. The request came as part of a real estate transaction, where the buyers or inspectors likely noted that the radon system was inactive. The radon fan is no longer operational and needs to be replaced before the sale can proceed.

Although there was no preliminary site visit, the seller left the Bilco door unlocked to allow interior access. The technician is expected to identify the location of the system and replace the defective fan with a new unit—matching the type and size as closely as possible unless a universal upgrade is necessary.

Since the home may be vacant or in staging, care should be taken to avoid any disruption and ensure that the new system is sealed, wired, and operational per state standards. This installation does not require re-routing piping or adding new extraction points—just a professional, efficient fan swap to restore the system's functionality before closing.

In Danbury, we were called to a historic home built in 1927 with a radon level of 4.2 pCi/L—just over the EPA’s actionable level. This house had two main foundations and a small crawl space, all made of cement. Although there was no water guard, the existing sump pump was already sealed, which provided a solid starting point for system planning.

We opted for a two-pipe mitigation system, with each pipe covering separate foundation zones to maximize suction and airflow. The crawl space did not require sealing or separate ventilation, which helped streamline the install. Given the age of the home and mixed foundation types, careful routing of the system was essential to avoid disrupting historic structural elements. No extra piping or encapsulation was needed, making this a clean and efficient install.

This setup now provides consistent radon control without the need for future upgrades, ensuring that even older homes like this one can meet modern indoor air quality standards.

The Westport project involved a 1960-built home with a standard concrete foundation and an additional cement crawl space—a configuration that often requires careful system design. The homeowner was particularly concerned, as they were preparing to move and wanted assurance that the system would be highly effective. At 13 pCi/L, the radon level presented a significant health risk and could delay the sale of the property if not addressed properly.

During consultation, it was determined that a three-pipe system would be necessary. The plan included two suction points in the air basement, positioned to maximize airflow across the slab, and a third pipe routed into the crawl space, where airflow is more limited. While there was no encapsulation, sump pump, or water guard to assist with air movement or moisture control, the system was designed to overcome these limitations.

The project addressed the homeowner’s concerns directly and delivered a tailored solution that’s both efficient and property-sale ready.

In Trumbull, the homeowner requested a radon mitigation system upgrade to improve airflow and add a more effective suction source. We began by addressing the system’s existing limitations: a 2-inch mitigation pipe that wasn’t pulling enough air volume.

To improve the system, we replaced the 2-inch pipe with a 3-inch pipe, allowing for significantly better suction and radon evacuation. Simultaneously, we added an extraction point inside a closet to target radon buildup from a specific zone within the home that previously lacked direct coverage. This newly added point connects seamlessly into the upgraded piping, ensuring balanced pressure throughout the system.

To finish, we securely capped the old 2-inch pipe, ensuring there would be no leakage or redundancy. This upgrade not only improves mitigation effectiveness but also prepares the home for long-term radon safety. The homeowner now has a streamlined, more powerful mitigation system ready for retesting.

In Monroe, CT, a proactive homebuyer took action to reduce radon levels before closing on their new home. With a radon test result of 6.4 pCi/L, they reached out for a quote and a system plan tailored to the home's layout. The house, built in 1979, features one main foundation and a sump pump located under the staircase. The homeowner mentioned it was already sealed, but our team will verify this during installation.

Since we weren’t able to conduct a physical walk-through, the client provided a detailed layout, noting that the utility room sits in the back left corner of the house, and requested that the exterior exhaust be routed out to the left side of the chimney. With that guidance, the team will be able to proceed efficiently after the October 30th closing. This forward-thinking mitigation not only ensures safety but also protects the home’s resale value.

This Westport property features a complex basement with four separate foundation sections, necessitating a four-pipe radon mitigation system for full coverage.

The project is being done in collaboration with David, the builder, who is taking a hands-on approach. David is installing the entire vertical pipe infrastructure: running Schedule 40 pipes from each foundation section, through a centrally located chase, and up through the cedar shake roof.

It was made explicitly clear to the builder that our team will not penetrate or modify the cedar roof in any way. All roofing tasks, including flashing and sealing, fall under the builder’s responsibility. David has also agreed to handle all drywall repairs post-installation.

Our role includes:

• Completing all basement-level connections for the four-pipe system.

• Installing the radon fan in the attic, with the expectation that electrical access is available at the fan location.

• Verifying system integrity and testing after setup is complete.

This partnership allows for a streamlined, high-efficiency system while minimizing aesthetic and structural disruption to the home. Builder coordination ensures proper timing and logistics before our team arrives on-site for final install and activation.

This Stamford job involves mitigating radon levels in a small Cape Cod home with a reported radon level of 5.1 pCi/L.

The home, built around 1950, has a single foundation, no sump pump, and no water intrusion history.

There is no encapsulation or extra piping, making this a relatively straightforward system install.

The client will leave the back door unlocked on the day of service, allowing for independent access. The radon system will be a one-pipe system, sized appropriately to the foundation and footprint of the house.

The team will determine the most effective and discreet run, ensuring minimum disruption and maximum efficiency, all while keeping aesthetic considerations in mind.

The job is expected to be completed efficiently in a single visit, with post-installation testing to ensure radon levels are brought below actionable thresholds.

For this Westport job, the homeowner has been proactive in requesting that the radon mitigation system integrate cleanly with their mostly finished basement. With a radon reading of 4.5 pCi/L, a single-pipe system is recommended.

The house, constructed in 1980, has one cement foundation, no crawl spaces, no sump pump, and no water guard system. The client directed that the system be placed within the mechanical room, which offers a direct pathway to the rear of the house. From there, they specifically requested that the radon exhaust pipe exit through the second bay on the right-hand side of the basement, a spot they identified as both discreet and optimal for venting.

The installation team will ensure the pipe is neatly routed from the suction point to the designated exterior location, taking care to preserve the integrity of the finished areas. This job is a perfect example of a collaborative approach where the client’s preferences were clearly communicated and factored into a custom, low-profile solution.

The Wilton property, built in 1954, has a radon level of 14 pCi/L and features two cement crawlspaces, one of which currently lacks an extraction point. The existing two-pipe system includes a run beneath the slab that exits outside. The fan is a RadonAway model, but its exact type (GP 201, 301, 401, or 501) is unknown as the label and install date are missing.

With the sale of the house scheduled for December 9th, the client requires two major updates to the current system:

1. Add a fourth extraction point in the rear crawlspace to ensure full coverage and reduce radon levels effectively.

2. Replace the fan with a clearly labeled and appropriately rated unit to meet post-sale compliance.

There is no sump pump, no water guard, no encapsulation, and no extra piping present. This job is a focused system enhancement for resale purposes, ensuring the expanded mitigation setup is both functional and verifiable for the buyer's inspection. All improvements must be carefully documented for transparency during the closing process.

Louise’s 1964 cement foundation home in Monroe had a radon level of 11 pCi/L, well above the EPA action level.  The home featured a single foundation and an existing sump pump located in the basement.

The challenge of this project centered around navigating a drywalled ceiling, which required discussion about cutting access paths for proper pipe routing. Additionally, we identified the need to upgrade the current sump pump to a more efficient 1/3 HP submersible model to support the system’s long-term moisture and pressure balance. A two-pipe mitigation system was recommended and designed for optimal extraction and airflow.

For this 1955 Trumbull property with no sump pump and no water guard, the homeowners wanted a one‑pipe mitigation system but needed guidance on placement.

Two installation options were presented: one near the oil tank in the center of the basement, and another in the corner of the home.

After discussing layout, accessibility, and future use of the space, the homeowner selected Option 2, placing the system in the corner.

Arrival was scheduled after 8:30 AM to accommodate the family’s morning routine.

The system will be installed with the necessary routing and exterior exit suited to the chosen location, ensuring effective radon reduction while maintaining the functionality of the basement.

This job required extra attention due to the tall structure and older 1908 fieldstone foundation.

Since there were no crawlspaces or sumps to work with, the team installed a two-pipe system, carefully navigating limited utility access points.

Clear instructions were followed regarding the unlocked access, pipe routing near the washer, and the need for extended vertical piping. The job was completed efficiently, balancing system performance with aesthetic discretion, leaving the home ready for safe occupancy by future renters.

This home tested at 5.5 pCi/L for radon, above the EPA recommended action level. Our team installed a clean, one-pipe radon mitigation system vented discreetly through the back right corner of the home. The system is designed to effectively reduce radon levels and help create a safer, healthier living space.

This historic home, built in the early 1900s, tested at a radon level of 11 pCi/L. A three-pipe mitigation system was installed, with two extraction points in the main foundation and one in the crawl space. The system was routed near the Bilco door, and cement work was completed to properly seal all extraction points, ensuring safe and effective radon venting.

In Cos Cob, we worked on a home built in 2008 where radon levels tested at 5.1 pCi/L. The home had a sealed sump pump, so we focused on placing the system where it would work best within the existing layout.

The mechanical room was too crowded and included a gas meter in a tight space, so it wasn’t a good option for installation. Instead, we installed a single-pipe radon mitigation system through a closet on the right side of the basement.

This allowed for a clean setup while avoiding tight or restricted areas.

We worked on a home built in 1974 where radon levels tested at 4.0 pCi/L. The home includes a crawl space with a cement slab that is large enough for access, which allowed for a more complete system design.

A three-pipe radon mitigation system was installed to cover all areas. One pipe was placed in a small closet, another was run horizontally into the slab, and a third was installed in the crawl space.

The crawl space line was routed into the shed, where the fan was installed, and then vented through the roof of the shed. This setup allowed the system to operate effectively while keeping the fan location separate from the main living space.

We also discussed the use of Aspen as part of the project considerations.

In Old Greenwich, we were called to evaluate a radon mitigation system where the homeowner reported excessive noise and vibration coming from the fan. The issue was noticeable enough to be felt throughout parts of the home.

The fan had been recently replaced, but the noise indicated that something was not functioning properly. We assessed the system to identify the cause, which can include improper installation, mounting issues, or airflow restrictions.

The goal is to ensure the system runs quietly and effectively without causing disturbance inside the home.

In New Fairfield, we worked on a colonial-style home built in 1987 with a partially unfinished basement. The layout required a system that could cover the unfinished section while staying out of the main living areas.

A two-pipe radon mitigation system was installed in the unfinished portion of the basement. One pipe was tucked behind the chimney to keep it out of the way, while the second was placed near the basement door for proper coverage.

This setup allowed for effective radon mitigation while keeping the installation clean and well-positioned within the space.

In Greenwich, we returned to a home where the radon level tested at 6.0 pCi/L. The property has four separate foundation areas, with an existing mitigation system already in place for one section.

We previously replaced the fan earlier this year, and the homeowner has been monitoring radon levels since then. Based on those results, the decision was made to expand the system to improve coverage.

Two additional extraction points were added—one in the crawl space and another in a closet—bringing the system to cover three of the four foundation areas. This approach allows the homeowner to address the most active sections first and evaluate whether the fourth area will need to be included later.

The system is now better aligned with the layout of the home, providing broader coverage while allowing flexibility for future adjustments if needed.

In Monroe, we visited a home where the radon mitigation system was producing a noticeable gurgling sound. This is often a sign of water collecting inside the pipe due to improper pitch or drainage.

To address the issue, the fan was replaced and the piping was adjusted to correct the pitch, allowing proper drainage within the system. We also installed a rain guard at the top of the pipe to help prevent water from entering.

With these corrections in place, the system is now running properly and quietly, with no gurgling noise.

In Wilton, we returned to a home to improve an existing radon mitigation system. The goal was to increase system performance by adding additional coverage and maintaining the current setup.

A second extraction point was added to better address the foundation area. At the same time, the original suction point was cleaned out to ensure proper airflow and system efficiency.

This combination of expanding and servicing the system helps improve overall performance and keeps the system running as intended.

In Westport, we completed a follow-up visit to check radon levels after initial mitigation work. A post-mitigation test was left in place, and results showed levels still at 4.5 pCi/L.

Based on these results, it was determined that additional coverage is needed to further reduce radon levels. The recommendation is to add two more extraction points to the existing system to better address the foundation areas.

This approach allows the system to be expanded in a targeted way, improving performance without starting over.

In Stamford, we worked on a home built in 1960 where radon levels tested at 12 pCi/L. The home has a single foundation with a slab configuration, which required a system designed to address both areas.

A two-pipe radon mitigation system was installed to provide proper coverage across the foundation and slab. With no sump pump or existing water management system in place, the setup focused on creating effective suction points to reduce radon levels.

The system was designed to provide consistent performance while working within the layout of the home.

In Weston, we worked on a home built in 1969 with an existing two-pipe radon mitigation system originally installed in 1994. The home has a high water table and a sealed sump pump, both of which can influence how radon moves beneath the foundation.

Radon levels were testing at 5.0 pCi/L, so improvements were made to the existing system to increase effectiveness. Both original extraction points were cleaned out to restore proper airflow, and a third extraction point was added in the crawl space to improve coverage.

The existing radon fan was also replaced with a new unit to ensure consistent system performance.

These updates allow the system to better address the foundation and crawl space areas while working with the conditions of the home.

In Darien, we replaced a radon mitigation fan on an existing system. The home had a RadonAway GP201 fan that was no longer operating as it should.

The old fan was removed and replaced with a new unit to restore proper airflow and system performance. Replacing the fan ensures that the system can continue pulling radon from beneath the home and venting it safely outside.

In Ridgefield, we worked on a home with significantly elevated radon levels, measuring over 40 pCi/L in the basement and between 10–14 pCi/L on the first floor. The home already had a mitigation system in place, along with a radon-in-water system, but additional improvements were needed to bring levels down further.

The homeowner has two young children and was understandably concerned, so the focus was on expanding and improving the existing system to increase effectiveness.

We upgraded the system by replacing the existing fan with a higher-capacity unit and adding multiple new extraction points throughout the basement. This included opening and cleaning out existing suction points, sealing a hole found in the basement, and adding additional lines in key areas such as the utility space, unfinished sections, and gym area.

The system was also adjusted to improve airflow and reduce noise, including the addition of a muffler. Special attention was given to areas where previous work had limited suction, particularly in sections with stone beneath the foundation.

This expanded setup provides broader coverage across the home and is designed to bring radon levels down more effectively.

In Trumbull, we evaluated an existing radon mitigation system originally installed in 2011. The homeowner reported that the system did not appear to be running.

We walked through basic troubleshooting, including resetting the breaker and cycling the system on and off, but the fan did not respond. The manometer reading was at zero (“U” level), indicating that the system is not actively pulling air.

During the exterior inspection, a section of piping appeared to be partially disconnected, which may also be affecting system performance.

Based on these findings, a fan replacement is likely needed to restore proper operation. Once the system is functioning again, follow-up testing is recommended to confirm performance.

In Norwalk, we worked on a home preparing for closing, where radon levels tested at 5.5 pCi/L. The property has a single foundation with no sump pump.

Due to the lack of an outlet in the basement, the radon test was set up in the front hallway to ensure proper monitoring.

A one-pipe radon mitigation system was installed, routed to the right rear corner of the home for exterior venting. The layout was designed to provide effective radon reduction while keeping the installation clean and appropriately positioned for the structure.

In Darien, we worked on a home built in 1997 where radon levels tested at 6.8 pCi/L. The homeowner was looking to install a mitigation system to address the elevated levels.

During the assessment, a large crack in the basement floor was identified as a potential entry point for radon. This was an important factor in designing the system.

A one-pipe radon mitigation system was installed near the fireplace and boiler area, allowing for effective suction while working within the layout of the home. The crack was also addressed as part of improving overall system performance and reducing radon entry.

The system was designed to provide reliable airflow while keeping the installation clean and properly positioned.

In Redding, we worked on a home with radon levels testing at 10 pCi/L. The property includes multiple foundation areas and crawl spaces, requiring a comprehensive system design.

A five-pipe radon mitigation system was installed to provide full coverage across the home. This included extraction points in the main foundation, crawl spaces, and an additional horizontal run connecting to a secondary crawl space area.

One of the crawl spaces, measuring approximately 25x20, was encapsulated to help control radon entry. The sump pump, approximately 30 inches in diameter, was sealed, and visible foundation cracks—covering a large area—were addressed to improve system performance.

Due to limited access in one crawl space opening, the focus was placed on sealing and adding an extraction point to ensure that area was still properly addressed.

As part of the service, a second radon test kit was left to allow for additional testing in a separate carriage house on the property.

In Bethel, we worked on a home built in 1937 where radon levels tested at 4.2 pCi/L. The homeowner had recently moved in and wanted to address radon levels early.

The home has a single foundation and a sump pump that was not sealed, creating a potential entry point for radon. To address this, a custom sump cover was installed to properly seal the area while accommodating the sump configuration.

A one-pipe radon mitigation system was installed, with the piping routed out the right side of the home when facing the property. The system was designed to work alongside the sump area while maintaining clean and effective airflow.

This approach provides reliable radon reduction while addressing key entry points in the basement.

In Trumbull, we reviewed a Cape-style home with a radon level of 3.9 pCi/L as part of a property being prepared for sale. The home is owned as an investment property and is currently in transition.

Based on the layout and available information, a three-pipe radon mitigation system was recommended. The design includes coverage for the main basement, crawl space, and slab areas, with the system routed out the left side of the home.

An exterior review of the property was completed, and photos were taken to help plan the installation. Interior access was not available at the time, so final system placement will be confirmed once access is provided.

We installed a premium radon mitigation system designed to improve airflow and provide more complete coverage throughout the basement.

The system includes a primary extraction point along with an additional suction point to help address multiple areas and improve overall performance. Both points work together to create consistent negative pressure beneath the slab.

Piping was routed through the basement in a clean and organized layout, then directed to the exterior where the fan was mounted. The system vents safely above the roofline, and a manometer was installed to allow for easy monitoring of system operation.

This setup provides reliable radon reduction while maintaining a clean appearance both inside and outside the home.

In Norwalk, we worked on a raised ranch home built in 1970 where radon levels tested at 16 pCi/L. The home has a single foundation with no sump pump or water management system in place.

To address the elevated levels, a two-pipe radon mitigation system was installed. One extraction point was placed in a closet area, and a second was installed in the garage to improve coverage across the foundation.

The system was routed out through the rear of the garage, providing a clean and practical exterior exit while maintaining effective airflow throughout the home.

This setup allows for better coverage in a split layout and helps ensure consistent radon reduction.

In Shelton, we reviewed a home built in 2002 with a radon level of 11 pCi/L. The property includes an unfinished basement with no sump pump, though a sealed drain is in place for a future bathroom.

As part of the upcoming home closing, a mitigation system was recommended to address the elevated levels. Based on the layout, a two-pipe system with an additional extraction point was proposed to provide better coverage across the foundation.

At this stage, access to the home was not available, so the system design is based on the information provided and will be confirmed once access is granted.

The homeowner is currently reviewing the proposal ahead of the closing date.

In Stamford, we reviewed a home built in 1963 where radon levels tested at 4.3 pCi/L shortly after the homeowners moved in.

The home includes a small basement along with a crawl space that is not currently accessible. There is also an existing water guard system in part of the basement, which helps manage ongoing groundwater conditions in the home.

Based on the layout, a two-pipe radon mitigation system was recommended. One extraction point is planned for the main foundation area, while a second horizontal pipe would extend toward the crawl space area to improve overall coverage.

The system design was developed to work within the limited basement space while addressing both the foundation and crawl space conditions.

In Westport, we worked on a home built in the mid-1960s where radon levels tested at 3.8 and 4.3 pCi/L in different areas of the property. The homeowner wanted levels reduced even further, with a goal of bringing readings below 2.7 pCi/L.

The home includes several unique foundation areas, including a crawl space and a separate wine cellar room located behind the boiler area. The property also has three sealed sump pumps installed by Connecticut Basement Systems, along with existing drainage components designed to manage groundwater.

To improve overall coverage, a three-pipe radon mitigation system was installed. One extraction point was placed in the main foundation, another in the crawl space, and additional piping was routed through the wine cellar area to address the smaller isolated space behind the boiler.

The crawl space piping was routed through the sill plate to maintain a clean layout while improving airflow beneath the home.

This system was designed to work alongside the existing waterproofing setup while providing more balanced radon reduction across all areas of the foundation.

In Monroe, we worked on a split-level home built in 1966 where radon levels tested at 5.3 pCi/L ahead of the homeowners’ upcoming move-in date.

The home includes a crawl space beneath the structure, with all sections connected under a single foundation. To address the elevated radon levels, a radon mitigation system was installed within the crawl space to improve airflow beneath the home.

The system was routed out the right side of the house near the boiler area, allowing for clean exterior venting while working within the layout of the split-level design.

This setup was designed to provide effective radon reduction before the homeowners moved into the property.

In Redding, we worked on a home built in 1982 where radon levels tested at 6.6 pCi/L. The property has a single cement foundation with approximately 1,800 square feet of basement space divided into two unfinished sections.

The homeowner chose to place the mitigation system in the smaller unfinished area located toward the front left side of the home when facing the property. This location allowed for a clean installation while effectively addressing the foundation area beneath the home.

A one-pipe radon mitigation system was installed to improve airflow beneath the slab and reduce indoor radon levels.

The system was designed to work within the layout of the unfinished basement while maintaining organized pipe routing and practical system placement.

In New Fairfield, we serviced an existing radon mitigation system after signs of fan performance issues were reported.

During the inspection, the liquid inside the manometer appeared discolored with a gold or pale tint, indicating the system had been operating for an extended period and required evaluation.

The existing radon fan was replaced to restore proper airflow and maintain reliable system operation. The manometer was also checked as part of the service visit to confirm system functionality after the replacement was completed.

A post-mitigation radon test kit was left behind so updated levels can be monitored following the fan replacement.

In Bethel, we installed a new radon mitigation fan to restore proper airflow and improve overall system performance.

The existing system required an updated fan to maintain consistent suction beneath the foundation and ensure reliable radon reduction throughout the home.

The new fan was installed as part of the active mitigation system, helping improve ventilation and support long-term operation of the radon setup.

In Trumbull, we reviewed a home preparing for new tenants after radon levels tested at 4.3 pCi/L.

The homeowner wanted to address the radon levels before the property became occupied again, helping provide a healthier indoor environment for future residents.

Based on the layout of the home, the mitigation system design may require routing through sections of drywall to create the best path for airflow and exterior venting. Special attention was given to keeping the installation as clean and organized as possible throughout the process.

The visit focused on planning the system layout and preparing the home for mitigation ahead of the upcoming tenant move-in.

In Ridgefield, we worked on a home with an existing five-pipe radon mitigation system to further improve basement air circulation and overall indoor air quality.

The basement space measures approximately 1,800 square feet and includes a drop ceiling, requiring careful planning for duct routing and vent placement throughout the area.

To support balanced airflow, an ERV Premium M ventilation system with four vents was installed. Approximately 250 feet of ductwork was routed throughout the basement to help improve fresh air exchange and circulation across the space.

The ventilation system was designed to work alongside the existing radon mitigation setup, helping improve airflow while maintaining a clean and organized installation within the finished basement layout.

In Brookfield, we evaluated an existing radon mitigation system after the homeowner reported radon levels around 7.6 pCi/L along with water remaining inside the system piping.

Water accumulation inside radon piping can interfere with proper airflow and reduce overall system performance if drainage or pipe pitch issues are present. The visit focused on reviewing the condition of the system and identifying whether adjustments or repairs may be needed to restore effective airflow beneath the foundation.

The system was inspected to help determine the source of the moisture buildup and evaluate overall mitigation performance following the elevated radon readings.

In Fairfield, we evaluated an existing radon mitigation system originally installed by another company after the homeowner reported increased fan noise since installation.

The visit focused on determining whether the system could be serviced or if a fan replacement might eventually be needed to restore quieter and more consistent operation.

At this stage, the appointment remained a diagnostic service visit only, allowing the system to be inspected and reviewed with the homeowner before any replacement work would be considered.

The goal was to assess overall fan performance and help determine the best long-term solution for maintaining effective radon mitigation while reducing operational noise.

In Greenwich, we worked on a property with multiple structures, including a main home with an existing passive radon system and a separate indoor pool area without passive mitigation in place.

To improve performance in the main home, a radon fan was added in the attic to convert the existing passive setup into an active mitigation system. The attic area included extensive spray foam insulation, requiring careful planning for fan placement and pipe routing.

The upgrade was designed to improve airflow beneath the foundation and provide more consistent radon reduction while utilizing the existing passive piping already installed in the home.

A post-mitigation radon test kit was also left behind so updated levels can be monitored after the fan installation.

In Wilton, we reviewed a home where radon levels tested at 4.8 pCi/L during the home sale process. The property includes a crawl space beneath the house with no traditional basement foundation.

The buyer needed a clean radon report before closing in order to help move the mortgage process forward. Due to time sensitivity surrounding the closing date, a mitigation system was planned to address the elevated levels as efficiently as possible.

Based on the available information, a one-pipe radon mitigation system was recommended for the crawl space area. The system design focuses on improving airflow beneath the home while working within the limitations of the crawl space-only foundation layout.

At this stage, the evaluation and planning process was completed remotely, with final placement details to be confirmed during installation.

In Sandy Hook, we replaced the fan on an existing radon mitigation system to restore proper airflow and maintain effective radon reduction throughout the home.

The fan replacement was completed to help ensure the system continues operating reliably and maintains consistent suction beneath the foundation.

In Stamford, we evaluated a home built around 1950 where radon levels remained elevated at 7.1 pCi/L despite an existing mitigation system already being installed.

The home has a single foundation, and the current system utilizes 4-inch Schedule 20 piping. Based on the elevated readings, additional improvements were discussed to strengthen airflow beneath the slab and improve overall mitigation performance.

Potential upgrade options included replacing sections of the existing piping, adding a second extraction point to increase sub-slab coverage, or installing a second mitigation system within the utility closet area.

The visit focused on reviewing the most effective approach for lowering radon levels further while working within the layout of the existing system and foundation design.

In Wilton, we evaluated a home built in 2009 where elevated radon levels remained present despite an existing mitigation system already being installed. The current system is original to the home, and improvements were needed ahead of the upcoming property sale.

To strengthen overall system performance, plans were made to replace the existing radon fan and add a second extraction point in the unfinished section of the basement near the furnace area.

The additional extraction point is intended to improve sub-slab airflow and provide broader coverage beneath the foundation, helping the system lower radon levels more effectively during the home sale process.

The visit focused on upgrading the original system while working within the existing basement layout and infrastructure.

In Darien, we evaluated an existing one-pipe radon mitigation system after radon levels continued testing at 6.8 pCi/L.

The home already had an active mitigation setup with a fan installed, but additional improvements were needed to strengthen airflow and improve overall radon reduction throughout the property.

As part of the upgrade plan, a second extraction point was added in the crawl space to improve sub-slab coverage and increase airflow beneath the home. The original extraction point was also opened and cleaned out to improve system performance.

Additional sealing work included creating a custom-fitted plexiglass cover for the sump pit and sealing two smaller openings in the concrete foundation to reduce potential radon entry points.

The overall system upgrade was designed to improve suction beneath the slab while tightening the foundation and crawl space areas contributing to elevated radon levels.

In Westport, we evaluated a split-level home built in 1957 where radon levels tested at 4.8 pCi/L.

The lower level of the home is being prepared for an elderly parent who will be moving into the space, making improved indoor air quality an important priority before the transition.

The home includes a crawl space beneath the split-level section of the foundation, which will be considered during the mitigation system design. Plans are also underway for future basement waterproofing improvements and a rear home addition, so the mitigation layout will need to work alongside upcoming construction and foundation updates.

The visit focused on reviewing the foundation layout and preparing a mitigation strategy that supports both current indoor air quality needs and future home improvements.

In Trumbull, we evaluated a radon mitigation system originally installed in 2005 after the homeowner reported that the fan had become noticeably louder over time.

As radon mitigation systems age, fan performance can gradually decline, and increased operational noise is often an early sign that service or replacement may be needed.

The visit focused on inspecting the existing fan and reviewing whether the issue could be addressed through service or if a replacement would provide the best long-term reliability and airflow performance.

Maintaining proper fan operation is important for keeping consistent suction beneath the foundation and supporting effective radon reduction throughout the home.

In Fairfield, we evaluated an existing radon mitigation system originally installed by a previous homeowner after concerns were raised about visible cracking in the exterior piping.

The homeowner noted that the system had last been tested approximately three years ago and wanted to determine whether additional hidden cracks or airflow issues might be affecting overall system performance.

The service visit focused on inspecting the visible piping, evaluating system airflow, and checking for signs of additional leakage or deterioration that may not be immediately visible from the exterior.

Over time, exposure to weather and aging materials can affect exterior mitigation components, making periodic inspections important for maintaining reliable radon reduction and proper airflow beneath the foundation.

In Wilton, we evaluated a home where radon levels tested at 4.3 pCi/L after the homeowner decided she wanted to further reduce long-term indoor radon exposure.

The homeowner has lived in the property for more than two decades and noted that the home may already include a radon pipe stub installed during original construction. After reviewing the existing layout, it was determined that using the original stub location would place the system in an undesirable area of the home with difficult exterior routing and highly visible vent placement.

Instead, a cleaner and more practical mitigation layout was recommended along the left side of the home when facing the property.

The home includes a full unfinished basement with no sump pump or crawl spaces. During the consultation, accessible foundation cracks were identified for sealing to help reduce additional radon entry points throughout the basement.

The visit focused on balancing effective radon reduction with clean system placement and long-term usability within the finished living areas of the home.

In Greenwich, we evaluated a home with radon levels testing at 6.4 pCi/L where the structure is primarily built on slab construction with one smaller foundation section.

Because the home does not include a crawl space beneath the structure and does not use radiant heat within the slab, the mitigation approach focused on exterior system placement and strategic extraction point locations to improve airflow beneath the home.

The primary design included a two-pipe mitigation system installed along the exterior near the AC units. The layout required exploratory access points to better understand the slab and foundation configuration before final extraction placement.

A secondary mitigation option was also discussed that would utilize a single extraction point positioned near the master bedroom area if field conditions required an alternate approach.

The planned extraction locations include one point near the bedroom section of the home and another beneath the window area within the original foundation section. The system design also includes a muffler to help reduce operational sound and maintain quieter performance near the living spaces.

Existing exterior electrical access is available for the fan installation, and ABS piping was selected as part of the proposed exterior routing design.

In Monroe, we reviewed a home with radon levels testing at 5.6 pCi/L and an unfinished basement foundation requiring mitigation improvements.

The basement includes a sump pump area that may require sealing enhancements to help reduce potential radon entry beneath the slab. Sealing exposed sump openings is an important part of improving overall mitigation effectiveness and strengthening airflow control beneath the foundation.

The project planning focused on improving sub-slab airflow while addressing potential entry points within the unfinished basement area.

At this stage, the consultation and layout planning were completed remotely prior to the on-site installation visit.

In Norwalk, we evaluated a home built around 1930 that includes both a crawl space and a concrete foundation section beneath the property.

The home does not include a sump pump or water management system, so the consultation focused primarily on understanding the crawl space and foundation layout to prepare for possible radon mitigation improvements.

Because older homes often contain multiple foundation styles and varying airflow conditions beneath the structure, the visit focused on reviewing the most effective approach for improving sub-slab communication and long-term indoor air quality.

The project planning included evaluating both the crawl space area and the concrete foundation section to determine the best mitigation strategy moving forward.

In Shelton, we worked with new homeowners preparing to move into their first home after radon levels tested at 21.1 pCi/L.

The home, built in 1992, does not include a sump pump or water management system, allowing the mitigation design to focus directly on improving airflow beneath the foundation.

Due to the elevated radon levels, a two-pipe radon mitigation system was recommended with venting planned along the right side of the home. The multi-point design was selected to improve sub-slab communication and provide broader airflow coverage beneath the foundation.

The homeowners planned to complete the on-site estimate process after moving into the property so the final system layout could be reviewed within the fully accessible home.

This project focused on helping first-time homeowners create a healthier indoor environment before fully settling into the space.

In Fairfield, we reviewed a home involved in a real estate transaction after radon levels tested at 4.4 pCi/L.

To support the home sale process and improve indoor air quality, a one-pipe radon mitigation system was planned for the property. The system layout was designed with venting routed along the side of the home near the exterior electrical area to maintain a clean and practical installation path.

The project focused on creating an effective mitigation solution while working within the existing exterior layout of the property during the transaction process.

In Trumbull, we evaluated an end-unit condo after radon levels tested at 4.8 pCi/L.

The condo, built in 2002, includes a partially unfinished basement area that provided a practical location for the mitigation system installation. A one-pipe radon mitigation system was planned within the unfinished section on the right side of the home when viewed from the front of the property.

The home does not include a sump pump or water management system, allowing the mitigation design to focus directly on improving airflow beneath the slab foundation.

The planned system layout was designed to provide effective radon reduction while working cleanly within the existing basement and garage access layout of the condo unit.

In Fairfield, we evaluated an indoor air quality system where accessible ductwork may require repair or adjustment to improve overall airflow and system performance.

The inspection focused on reviewing exposed duct sections that were accessible without opening finished walls, allowing potential airflow or connection issues to be identified more efficiently.

As part of the visit, a complimentary sanitizing treatment was also included to support cleaner indoor air circulation throughout the home.

The overall goal was to improve airflow reliability while helping maintain healthier indoor air quality within the living space.

Job Story

In Fairfield, we evaluated a home with radon levels testing above 4.0 pCi/L where multiple foundation conditions were contributing to a more complex mitigation design.

The property includes a standard slab foundation area along with a separate section containing large exposed boulders beneath the home. That area, measuring approximately 23 by 13 feet, was identified for encapsulation to help isolate exposed ground conditions and improve long-term airflow control beneath the structure.

Because the home includes multiple foundation sections and varying sub-structure conditions, a minimum three-pipe radon mitigation system was recommended to provide broader airflow coverage beneath the property.

Additional radon testing was also planned in other sections of the home to better understand how radon levels may vary between the different foundation areas before final system placement is completed.

The consultation focused on developing a mitigation strategy that addresses both the slab foundation and the exposed earth and boulder section beneath the home to support improved indoor air quality throughout the property.

In Trumbull, we evaluated a home built in 1952 after a recent inspection identified radon levels at 10.3 pCi/L.

To improve airflow beneath the foundation and strengthen overall radon reduction, a two-point extraction mitigation system was recommended. Multiple extraction locations were reviewed during the consultation, including the possibility of placing an additional extraction point near the center of the basement area to improve sub-slab communication.

The home also included existing unused penetrations through the siding from previous piping, which may be incorporated into the final vent routing design to help minimize additional exterior modifications and maintain a cleaner installation appearance.

During the consultation, future basement waterproofing considerations were also discussed. Potential sump pump placement areas were reviewed so any future water management improvements can work alongside the radon mitigation system layout if needed later on.

The project planning focused on balancing effective airflow coverage, practical pipe routing, and long-term flexibility for future foundation improvements.

In Ridgefield, we evaluated a home built around 1900 after radon levels tested at 9.5 pCi/L.

The home includes an existing water management system around the basement perimeter, and additional sealing improvements are planned separately to help strengthen overall foundation protection and airflow control beneath the home.

A one-pipe radon mitigation system was designed with the extraction point planned near the sump area in the basement corner. The vent routing is planned toward the rear side of the home to provide effective sub-slab airflow while maintaining a clean exterior installation layout.

Because older homes often include varying foundation conditions and airflow pathways beneath the structure, the system design focused on improving long-term radon reduction while working within the existing basement and foundation configuration.

The homeowners had recently relocated from Florida and were working to improve indoor air quality as part of settling into their new home.

In Westport, we evaluated a home with two separate existing radon mitigation systems already installed on the property.

One system included a single extraction point but did not have a manometer installed for airflow monitoring. The second system also operated with a single extraction point and included piping running beneath an encapsulated CleanSpace area. Both exterior fans were mounted side-by-side outside the home, with one system dating back to 2012 and the other installed in 2016.

The project involved replacing both aging radon fans to improve long-term airflow performance and system reliability. In addition, both extraction points were scheduled to be cleaned to improve sub-slab communication and restore stronger airflow beneath the foundation.

During the inspection, one of the systems was found to contain standing water within the piping, indicating that drainage slope and pipe pitch would need to be evaluated and corrected if necessary to restore proper airflow conditions.

A new manometer was also planned for the single-pipe system to allow easier monitoring of system operation and suction performance moving forward.

Because groundwater conditions may also be contributing to moisture beneath the slab, future sump pump considerations were discussed as part of the long-term foundation and mitigation strategy.

In Bethel, we reviewed an existing radon mitigation system after follow-up testing continued to show radon levels around 4.5 pCi/L.

To improve airflow beneath the home and strengthen overall mitigation performance, additional extraction coverage was recommended within the crawl space areas. The updated design includes adding two more extraction points, with one planned for each crawl space section to improve sub-slab communication and expand airflow coverage beneath the foundation.

The project focused on enhancing the performance of the existing mitigation setup while addressing foundation areas that may not have been fully covered by the original system design.

A post-mitigation radon test kit was also provided to help verify system performance after the additional extraction improvements are completed.

In New Fairfield, we evaluated a home built in 1987 where radon levels have been testing between 3 and 5 pCi/L.

The home includes a single foundation and experiences a naturally high water table beneath the property, although no sump pump system is currently installed.

To improve airflow beneath the slab and support lower long-term radon levels, a one-pipe radon mitigation system was recommended along with sealing accessible foundation cracks to help reduce potential radon entry points.

During the consultation, exterior vent routing options were still being reviewed to determine the cleanest and most effective placement for the final system installation.

The project focused on improving sub-slab airflow while strengthening the overall foundation seal within the basement area.

In Greenwich, we evaluated a home built around 1960 after radon levels tested at 7.35 pCi/L shortly after the homeowners moved into the property.

The basement is currently under renovation, with the lower level opened up for construction work. This created an ideal opportunity to address radon mitigation and foundation sealing improvements before the basement is finished.

The home includes two sump pump systems with existing covers that require additional sealing improvements to help reduce potential radon entry beneath the slab. The basement also includes a perimeter water management system that will require sealing as part of the overall mitigation strategy.

A one-pipe radon mitigation system was designed with venting planned along the right side of the home to improve airflow beneath the foundation and support long-term indoor air quality improvements.

In addition to the mitigation system installation, approximately 98 feet of foundation and perimeter sealing work was identified to strengthen airflow control beneath the basement slab and around the water management system.

In Greenwich, we evaluated a historic home built around 1920 where radon levels tested at 5.0 pCi/L across a complex foundation layout that includes one main foundation area and two crawl spaces.

Because the home features older field stone foundation construction, the mitigation strategy required careful planning to improve airflow beneath multiple sections of the structure while working within the existing foundation conditions.

A three-pipe radon mitigation system was designed to provide broader airflow coverage beneath both crawl spaces and the primary foundation area. The vent routing is planned along the right side of the home behind the chimney to maintain a cleaner exterior appearance.

The home also includes a sump pump and perimeter water management system, both of which were reviewed as part of the mitigation planning process.

During the consultation, an existing ERV ventilation system was discussed after the homeowner noted limited improvement in overall indoor air quality performance. Additional foundation sealing work was also identified, including sealing a crack near the washer and dryer area around existing plumbing penetrations.

The project focused on improving sub-slab airflow, strengthening foundation sealing, and addressing the unique challenges that often come with older field stone construction.

In Newtown, we evaluated a small ranch-style home built around 1959 after radon levels tested at 26 pCi/L.

Because the basement is mostly finished living space, careful planning was needed to create effective airflow beneath the foundation while keeping the mitigation system routed cleanly through the unfinished utility section of the basement.

A two-pipe radon mitigation system was designed with both extraction points planned within the unfinished basement area to improve sub-slab communication and strengthen airflow coverage beneath the home.

The vent routing is planned along the left side of the house near the existing utility equipment area, helping maintain a cleaner and more organized exterior system layout.

With radon levels significantly elevated, the project focused on creating strong airflow beneath the slab while minimizing impact to the finished portions of the basement living space.

In Stamford, we evaluated a home after radon levels tested at 8.3 pCi/L across a complex foundation layout that included multiple crawl spaces and finished basement areas.

The homeowners wanted to preserve flexibility for future basement finishing, so the mitigation design avoided the basement room with windows that may later become finished living space.

To provide stronger airflow coverage beneath the home, a four-pipe radon mitigation system was designed. The layout includes one extraction point in each crawl space along with two additional extraction points within the main foundation area to improve sub-slab communication throughout the structure.

Because of limited routing options around the property, the venting system was carefully planned along the left side of the home. The opposite side of the house includes garage access limitations, while the rear exterior contains a finished pool and patio area that the homeowners wanted to preserve aesthetically.

To maintain a cleaner appearance inside the basement, the piping layout was designed to remain tucked tightly along the upper ceiling areas wherever possible.

The project focused on balancing strong mitigation performance with future basement plans, limited routing access, and preserving the overall appearance of the property.

In Shelton, we returned to service an existing radon mitigation system after the homeowner noticed elevated readings on their Airthings monitor, with radon levels reportedly increasing to around 10 pCi/L.

The homeowner also noted concerns related to system airflow and monitoring, including questions surrounding the manometer readings and overall system performance.

During the service visit, the existing Sedona dehumidification system and radon fan setup were inspected and serviced to improve overall airflow and indoor air quality performance throughout the basement.

The inspection also identified a failed GFCI outlet affecting system operation. The outlet was replaced to restore reliable electrical service to the mitigation equipment and associated basement air quality systems.

Additional maintenance and filter evaluation for the Sedona system were also reviewed as part of the overall service process to help support continued airflow efficiency and long-term system reliability.

The project focused on restoring dependable system performance while helping the homeowner better monitor indoor air quality moving forward.

In Trumbull, we evaluated a home built in 1979 after radon levels tested at 7.9 pCi/L.

The homeowner had previously tested the property several years ago and already understood that mitigation improvements would eventually be needed to reduce long-term indoor radon exposure.

A one-pipe radon mitigation system was designed with placement planned near the basement window area to improve airflow beneath the slab while working within the existing basement layout.

The home uses a boiler and radiator heating system, which was considered during the planning process to maintain clean pipe routing and proper equipment placement throughout the utility area.

Additional testing performed in the room above the garage showed lower radon levels in that section of the home, helping provide a better understanding of how airflow conditions vary throughout the property.

The project focused on improving sub-slab airflow beneath the main foundation while creating a practical system layout that works within the existing structure.

In Redding, we evaluated a vacant home after radon levels tested at an extremely elevated 67 pCi/L.

The property already included an existing one-pipe radon mitigation system, but the current fan was no longer operating, leaving the system unable to maintain active airflow beneath the foundation.

Because of the unusually high radon levels and the limitations of the original single-point design, a major mitigation upgrade was planned for the home. The updated design includes replacing the failed fan and adding four additional extraction points throughout the unfinished basement to dramatically improve sub-slab communication and airflow coverage beneath the foundation.

The home includes a single foundation with no sump pump, crawl space, or exposed earth conditions, allowing the mitigation strategy to focus entirely on strengthening airflow beneath the slab itself.

The project planning focused on transforming the existing limited system into a much stronger multi-point mitigation design capable of addressing significantly elevated radon conditions throughout the home.

Detailed system documentation and layout planning were also prepared as part of the installation process to support proper placement and long-term mitigation performance.

In Shelton, we followed up with a homeowner after a recently installed radon mitigation system was reported to be operating louder than expected.

Although the system was functioning properly, the homeowner wanted to further reduce operational sound levels within the living environment. To improve acoustic performance, a muffler upgrade was recommended to help soften airflow noise and create quieter day-to-day system operation.

Sound reduction can be an important part of long-term homeowner comfort, especially in homes where mechanical equipment is located near commonly used living spaces.

The planned visit focused on refining the existing mitigation setup while maintaining strong airflow performance and continued radon reduction beneath the foundation.

In New Canaan, we responded to a service concern after the homeowner reported water entering the basement through the existing radon mitigation system piping.

As a precaution, the homeowner shut the system off after noticing water intrusion associated with the mitigation setup.

The service visit focused on evaluating the source of the water entry, reviewing the condition and pitch of the existing piping system, and determining whether groundwater conditions or drainage issues may be affecting the mitigation system’s operation.

Water intrusion within radon piping can sometimes indicate drainage, condensation, or groundwater management concerns that require adjustments to airflow routing or system design to restore proper operation.

The inspection was designed to identify the cause of the issue and develop a solution that restores reliable mitigation performance while protecting the basement environment from future moisture concerns.

In Fairfield, we evaluated a complex radon mitigation challenge after recent testing measured radon levels at 9.4 pCi/L despite an existing mitigation system already being installed at the home.

The property includes a slab-on-grade foundation built over ledge conditions, along with multiple separate foundation sections beneath the structure. The current mitigation system is more than 14 years old and only actively addresses one portion of the home, although the fan itself was replaced approximately three years ago and remains operational.

The homeowner also located older testing records showing that radon levels had previously been roughly half of the current readings, confirming that conditions beneath the home have changed over time.

Because portions of the home include ductwork buried within the concrete slab and several isolated foundation areas, the mitigation redesign required advanced planning to improve airflow communication across multiple sections of the structure.

The updated strategy includes raising the existing fan and adding a second exterior extraction point to strengthen airflow beneath the currently mitigated slab section.

In addition, a separate three-pipe mitigation system was planned for a cinder block “bunker” area located near the boiler room at the front of the home. The layout includes two extraction points along the longer wall section and one extraction point along the shorter rear wall to improve airflow coverage within that isolated foundation area.

The project also includes exterior excavation work near the front of the house to support additional piping and fan placement for the expanded mitigation layout.

One remaining middle foundation section continues to present design limitations due to restricted access and limited locations for additional mitigation or ventilation equipment placement.

This project focused on redesigning and expanding the mitigation approach across multiple isolated foundations to improve long-term radon reduction throughout a uniquely challenging structure.

In Shelton, we evaluated a vacant home after radon levels tested at 24 pCi/L within the unfinished basement area.

Although there had been previous discussion suggesting the home may have included a passive radon system, a full attic inspection confirmed that no passive mitigation infrastructure was present within the property.

Because of the elevated radon levels and unfinished basement layout, a two-pipe radon mitigation system was designed to improve airflow coverage beneath the foundation and strengthen long-term radon reduction throughout the home.

Special attention was given to the exterior vent routing design to ensure the mitigation system exits through the rear of the home, preserving the preferred appearance and layout of the property.

The project focused on creating strong sub-slab airflow coverage while maintaining clean exterior system placement and preparing the vacant home for healthier indoor air quality moving forward.

In Bridgeport, we responded to a service concern involving a leaking roof boot associated with an existing radon mitigation system.

The inspection focused on evaluating the roof penetration area where the vent pipe exits the home to identify the source of the water intrusion and determine whether the flashing or boot seal had deteriorated over time.

Roof boot and flashing components play an important role in protecting the home from moisture intrusion while allowing the mitigation system to vent safely above the roofline.

The service visit was designed to identify the cause of the leak and restore proper sealing around the vent penetration to help protect both the roofing system and the interior of the home.
