In Wilton, we evaluated a home built around 1985 after the homeowner continued experiencing elevated radon levels around 5.2 pCi/L despite already having an active mitigation system in place.

The homeowner explained that multiple previous mitigation attempts had already been made, including recent service work involving fan replacement, sump sealing, and vent pipe adjustments.

Additional waterproofing and basement system recommendations had also been discussed by other contractors, but the radon levels remained higher than the homeowner was comfortable with.

Because the homeowner works from home and spends significant time inside the property each day, finding a dependable long-term solution was especially important during the consultation.

The existing system currently operates with a single extraction point and an XP201 fan. After reviewing the airflow conditions and ongoing radon readings, additional system expansion was recommended to improve sub-slab communication beneath the home.

The updated plan includes adding a second extraction point within the utility room area toward the front portion of the house to improve airflow coverage beneath additional sections of the foundation.

The existing fan setup will also be reevaluated during the visit to determine whether upgrading to a stronger fan model may improve overall suction performance and help strengthen long-term radon reduction throughout the home.

The project focused on expanding the existing mitigation system and refining airflow performance to provide a more effective long-term indoor air quality solution.

In Wilton, we evaluated a home after radon levels tested at approximately 11 pCi/L shortly after the property was purchased.

The new homeowner wanted the mitigation work completed before moving into the home to help improve indoor air quality from the start of occupancy.

The property includes three separate foundation sections, including two concrete crawl spaces and one primary basement foundation area. Because homes with multiple foundation sections often experience uneven airflow beneath the structure, a broader mitigation layout was recommended to improve long-term radon reduction performance.

A three-point radon mitigation system was designed with vent routing planned along the left side of the home. Within the main basement foundation, the primary system placement was planned behind the basement stair area to maintain a clean and practical installation layout.

During the consultation, portions of the lower-level areas were also identified as candidates for future encapsulation improvements to further strengthen airflow control beneath the home. Separate planning and pricing discussions were completed for those future encapsulation phases, though the initial work will focus only on the mitigation system installation itself.

The project focused on creating strong airflow communication beneath all three foundation sections while preparing the home for healthier long-term indoor air conditions prior to move-in.

In Wilton, professional dryer vent cleaning service was scheduled to help improve airflow efficiency and support safer operation of the home’s laundry ventilation system.

Over time, lint and debris can gradually build up within dryer vent lines, reducing airflow performance and placing additional strain on the dryer system. Routine cleaning helps improve ventilation efficiency while supporting better long-term appliance performance.

The service visit focused on inspecting and cleaning the dryer vent pathway to help restore proper airflow throughout the system and reduce excess buildup within the vent line.

Maintaining clean dryer vent systems is an important part of supporting healthier indoor air conditions and improving overall home safety.

The project centered on restoring proper ventilation performance and helping maintain reliable long-term operation of the home’s laundry system.

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 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 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.

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.

A Wilton homeowner reached out concerned that his radon mitigation fan—originally installed around 20 years ago—was no longer working. Without needing an initial site visit, he sent a photo of the existing fan setup. We advised that the issue likely warrants a full fan replacement and gave upfront pricing: $185 for diagnostic service or $695 for replacement. The technician was instructed to text upon arrival, as either the homeowner or his wife would be available during the visit. The photo confirmed the need for evaluation, and we’re prepared to act swiftly upon arrival to ensure proper radon mitigation is restored.

In Wilton, CT, we worked on a 1950-ish split-level home with a radon reading of 2.6 pCi/L. Though below the EPA’s threshold, the homeowner wanted peace of mind. A two-pipe system was installed, with one line running through a crawl space that required concrete patching in certain areas for better suction and sealing.

The system exits the left side of the home, carefully routed in the middle of the stair section to the right of the front door, discreetly positioned in a fenced section of the exterior. The layout supports future maintenance while maintaining aesthetics.

We also ensured clear communication with the homeowner—texted Michael upon arrival as instructed.

This Wilton property, built in 1959, had a radon level of 4.1 pCi/L. The homeowner, preparing to sell, requested a fan replacement and sump pump sealing to bring the system back to optimal condition.
The house features two foundations and has both a sump pump and water guard, which the seller plans to further seal with CT Basement Systems. We also left a monitoring machine on-site to allow for accurate post-installation retesting.

In Wilton, CT, a 1956 ranch-style home faced a challenging radon level of 7.4. With no existing sump pump, our task was to design a radon mitigation system that could efficiently reduce indoor radon levels while integrating smoothly with the home's structure. The solution involved running the mitigation pipe through the interior, exiting through the garage roof. Wide Melissa, the homeowner, facilitated the process by providing access through the right side door of the house. Our team ensured floor protection with tarps and executed a flawless installation, plumbing the radon reduction system through the roof for optimal performance and minimal visual impact. This project highlights our expertise in customizing radon mitigation solutions tailored to specific home layouts and homeowner needs.

In tackling the radon issue in a 1961 Wilton home with a level of 7.3, we provided a customized approach that resonated with the homeowner’s needs. During the consultation, the placement of the radon system was strategically decided to ensure efficiency and homeowner comfort. Special attention was given to sealing potential entry points for pests, particularly following an incident with a bat. The project also included sealing the sump pump and addressing inaccessible areas around the basement, with plans for further action based on the homeowner's ongoing feedback and a full water test scheduled for the next visit. This comprehensive approach highlights our commitment to detailed, client-focused service and ensuring long-term safety and satisfaction.

When Melanie visited the Wilton property for a consultation, homeowner Matthew emphasized the importance of both safety and aesthetic appeal in the installation of a radon mitigation system. Taking these factors into account, our installation team designed a system that not only addressed the radon levels effectively but also maintained the home’s visual integrity. The system was installed in the utility room with the vent pipe directed towards a downspout, cleverly hiding the fan behind a lattice fence. Aware of the large basement size, we also discussed the potential addition of a second system, ensuring the homeowners are prepared for comprehensive radon mitigation if needed. This thoughtful planning and execution underscore our commitment to delivering solutions that meet both safety standards and homeowner expectations.
