In Westport, a homeowner elected to address radon levels after testing measured approximately 4.3 pCi/L during the home selling process. With a scheduled closing date of July 30, the homeowner wanted to proactively install a mitigation system to help support the transaction and provide peace of mind for future occupants.

The home features a partially finished and partially unfinished basement. After evaluating the foundation layout, a one-point radon mitigation system was recommended. The extraction point and vent piping will be routed out the left side of the home, providing an effective and discreet installation.

The homeowner had received several other mitigation proposals before selecting Apex Radon Solutions and wanted a professional solution designed for long-term radon reduction and reliable performance.

In Westport, we evaluated a colonial-style home built in approximately 1963 after radon testing measured 5.0 pCi/L.

The home contains two foundation sections and an existing water management system with water guard installed. Because homes with multiple foundations can experience varying radon entry patterns, we reviewed several mitigation approaches to determine the best long-term solution.

During the consultation, two mitigation options were discussed and quoted for the homeowner. Both options were designed to address the home's elevated radon levels while taking into account the existing foundation layout and water management system.

The proposed design includes a one-point radon mitigation system with the vent piping routed along the left side of the home. The system will create negative pressure beneath the foundation and safely vent radon gas above the roofline before it can enter the living space.

The existing water guard system will be considered during installation to ensure proper integration with the mitigation design and to maximize overall system effectiveness.

The project focuses on reducing radon levels, improving indoor air quality, and providing the homeowner with options that best fit the home's foundation configuration.

In Westport, a crawl space encapsulation project was scheduled to improve the condition and performance of the home's lower-level environment.

The work will focus on encapsulating approximately 30 feet by 5 feet of exposed crawl space wall area. Encapsulation helps create a cleaner, more controlled environment by isolating foundation surfaces from surrounding soil conditions and reducing unwanted air movement through the crawl space.

Properly sealed crawl space areas can contribute to improved moisture control, support overall indoor air quality goals, and enhance the effectiveness of any existing radon or ventilation systems serving the home.

The project was designed to address the exposed wall section identified during the evaluation and provide a durable, professional finish that supports long-term crawl space performance.

The focus of the work is to improve environmental control within the crawl space while creating a cleaner and more manageable foundation area.

In Westport, we evaluated a single-family colonial home after radon testing measured approximately 4.2 pCi/L. While the radon level is relatively modest, the home's complex foundation layout and multiple open foundation areas make proactive mitigation and encapsulation improvements an effective long-term solution.

The home features an unfinished basement, multiple crawl spaces, a sump system, and four separate foundation sections. Several exposed areas and water management channels were identified that would benefit from encapsulation to improve soil gas control and overall system performance.

The mitigation design includes a four-point radon system serving the various foundation sections of the home. The vent system is planned to exit along the left side of the house when viewed from the front.

Several encapsulation areas were identified during the consultation, including a 10' x 10' crawl space, exposed water guard sections measuring approximately 10 feet and 5 feet in length, a smaller corner area of approximately 5 feet, and an additional crawl space area measuring approximately 11' x 7' x 22'. Addressing these spaces will help improve airflow control beneath the home and enhance the effectiveness of the mitigation system.

The existing sump pit already has a lid in place and will be further sealed as part of the project. A Sedona dehumidifier installation is also planned at the sump area to help manage moisture levels and support healthier indoor air quality throughout the lower levels of the home.

In addition, a duct cleaning flyer will be provided to the homeowner during the visit.

The project focuses on combining radon mitigation, crawl space encapsulation, sump sealing, and moisture control into a comprehensive indoor air quality solution for the home.

In Westport, we planned the installation of an Energy Recovery Ventilator (ERV) to improve air circulation and overall indoor air quality throughout the home's lower levels.

The system design includes a fresh air intake and exhaust connection serving the main foundation area, along with a dedicated exhaust branch designed to pull air from the crawl space. This approach helps promote balanced air exchange while reducing stagnant air conditions in both the basement and crawl space environments.

The installation will require approximately 150 feet of ductwork to properly connect the intake, exhaust, and crawl space ventilation pathways. Two exterior vent terminations will also be installed to allow the ERV to bring in fresh outdoor air while exhausting stale indoor air.

By continuously exchanging indoor and outdoor air, the ERV will help improve ventilation efficiency and support healthier indoor air conditions throughout the home.

A Continuous Radon Monitor (CRM) will be left on-site following installation to document post-installation conditions and verify system performance.

The project focused on improving whole-home ventilation, enhancing crawl space air movement, and creating healthier long-term indoor air quality conditions.

In Westport, we evaluated an existing radon mitigation system after additional testing showed elevated readings in multiple areas of the home.

Two separate radon tests were completed — one within the finished basement area, which measured approximately 7 pCi/L, and another within the unfinished section of the basement, which measured approximately 11.7 pCi/L.

The home currently operates with a two-point mitigation system, including one extraction point in the unfinished basement and another connected to an older encapsulated crawl space beneath the home.

Because the current mitigation fan is no longer functioning properly and elevated readings remain throughout multiple foundation sections, a broader system upgrade was recommended to improve long-term airflow performance beneath the structure.

The updated plan includes replacing the failed mitigation fan and adding a third extraction point within the finished basement foundation area. The new extraction point will require drilling through a concrete wall to improve sub-slab communication across the separate basement sections.

The encapsulated crawl space will also be inspected during the visit to verify that the vapor barrier remains securely attached and continues providing proper airflow control beneath the crawl space area. If deterioration or separation is identified, additional repair or replacement recommendations may be provided.

The project focused on restoring reliable system operation, expanding airflow coverage beneath all foundation sections, and evaluating the condition of the older crawl space encapsulation system to improve long-term indoor air quality throughout the home.

In Westport, we evaluated a home after radon levels tested at approximately 6 pCi/L despite an existing mitigation system already being in place.

The property includes three separate concrete basement sections connected to a five-point extraction system currently operating with a Legend Extreme radon fan. Because homes with multiple foundation sections can experience uneven airflow beneath the slab, maintaining balanced suction across all extraction points is especially important for long-term mitigation performance.

The consultation focused on reviewing the existing multi-point system layout and evaluating overall airflow conditions beneath the three connected basement areas to improve long-term radon reduction performance throughout the home.

With larger and more complex foundation layouts, even existing mitigation systems may occasionally require airflow adjustments, extraction cleaning, or system upgrades over time to maintain consistent performance across all sections of the structure.

The project centered on strengthening airflow communication beneath the multiple basement areas while maintaining reliable long-term indoor air quality protection throughout the home.

In Westport, we coordinated professional radon testing for a home with an existing mitigation system estimated to be approximately 20 years old.

The homeowner expressed uncertainty about whether the older system is still operating effectively and wanted updated testing completed before determining whether additional service or system improvements may be needed.

Because radon mitigation systems operate continuously for many years, periodic testing is an important way to confirm that airflow conditions beneath the foundation are still performing as intended and maintaining healthy indoor air quality throughout the home.

The testing plan focused on establishing current radon levels and evaluating overall system effectiveness before making recommendations regarding future servicing or equipment updates.

The project centered on helping the homeowner better understand the current condition and performance of the long-standing mitigation system through updated professional monitoring.

In Westport, we scheduled service for an existing radon mitigation system after the homeowner reported the need for fan replacement following approximately ten years of system operation.

Radon mitigation fans operate continuously to maintain airflow beneath the foundation, and over time, normal wear can reduce efficiency or lead to operational concerns that require replacement.

The service visit focused on restoring dependable sub-slab airflow and maintaining long-term indoor air quality protection throughout the home.

Replacing aging fan equipment helps ensure the mitigation system continues operating reliably and provides consistent radon reduction performance moving forward.

The project was planned as a straightforward service upgrade designed to maintain healthy airflow conditions beneath the home for years to come.

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 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 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.

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.

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 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 Westport, we were called in to assess a 20-year-old radon mitigation fan that had grown loud enough to disrupt daily life. Our team quickly diagnosed the issue and replaced the outdated unit with a new, energy-efficient model, restoring proper airflow and eliminating noise. No additional system modifications were required — just a straightforward swap that brought immediate results. The client now enjoys a silent, fully functioning system that meets modern standards.

In this Westport, CT home, we faced a dirt crawl space with damaged CleanSpace and drainage matting. The radon levels measured 5.3 pCi/L, requiring a reliable two-pipe system.

What made this job unique: there was no existing electrical access in the crawl space. Instead of requiring the homeowner to hire an electrician, our team built an external outlet and completed the electrical connection for the radon fan.

We entered the crawl space carefully, using full coveralls and knee protection to protect the matting. The system now exits the right side of the house, fully functional and ready to keep the air safe.

With a radon level of 3.5 pCi/L, this homeowner in Westport took proactive steps to secure their basement environment. The home, built in 1964, had an unfinished basement, two sump pumps (one already sealed), and was an ideal candidate for a two-pipe mitigation system.

We advised the homeowner to move items around the intended install zone and placed one of the pipes between two A/C units on the left exterior side of the house — an efficient and discreet placement for long-term safety.

In Westport, CT, a homeowner was dissatisfied with the noise from an existing radon mitigation fan in their 2002-built, 120,000 sq ft mansion. With an average radon level of 2.2, they aimed not only to reduce the noise but also to explore options for healthier air. Our solution involved installing a new, quieter fan and deploying three radon CRMs to ensure continuous monitoring and adjustment. Positioned in the mansion’s basketball court, gym, and wine cellar, these measures were designed to maintain optimal air quality across diverse living spaces.

In 2002, a grand Westport home spanning 120,000 sq ft faced issues with a noisy radon mitigation fan and an average radon level of 2.2. The homeowner desired a quieter and more efficient system to ensure optimal indoor air quality. Our tailored approach included replacing the noisy fan and deploying three radon Continuous Radon Monitors (CRMs) in key locations: the home's basketball court, gym, and wine cellar. This precision-targeted installation underscores our commitment to providing bespoke solutions that cater to the unique needs and amenities of luxury properties.
