In Ridgefield, we scheduled a Continuous Radon Monitor (CRM) test for a homeowner who has not tested the property for radon in more than 20 years.

Because radon levels can change over time due to natural soil conditions, weather patterns, home improvements, and foundation changes, updated testing is an important step in understanding current indoor air quality conditions.

The homeowner wanted current information about radon levels within the home, and professional CRM testing will provide accurate measurements throughout the monitoring period. The results will help establish a clear picture of present-day radon conditions and determine whether any additional recommendations may be beneficial.

Given the amount of time since the last test, obtaining updated data will provide valuable insight into the home's indoor environment and help ensure informed decisions moving forward.

The project focuses on providing reliable radon testing and helping the homeowner better understand current indoor air quality conditions through professional monitoring.

In Ridgefield, we evaluated a two-story colonial home after radon testing measured approximately 20.3 pCi/L.

The homeowners built the house about 14 years ago and believe the property was constructed with radon-ready piping already installed beneath the foundation. During the consultation, an existing pipe stub with a tee connection was identified in the basement, indicating that the home may have been prepared for future activation of a radon mitigation system.

The home has no crawl spaces or sump systems and features a basement that is approximately 70% finished. Because much of the lower level is already completed, utilizing the existing radon-ready infrastructure provides an efficient way to improve airflow beneath the slab while minimizing disruption to finished areas.

The planned mitigation approach focuses on activating the existing piping system and routing the vent toward the backyard to maintain a clean exterior appearance while achieving effective radon reduction.

Homes that are constructed with radon-ready components often allow for a streamlined mitigation installation by building upon infrastructure already present beneath the foundation.

The project focused on converting the existing radon-ready setup into a fully functioning mitigation system to significantly reduce radon levels and improve long-term indoor air quality throughout the home.

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 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 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 Ridgefield, CT, we worked on a spacious home with an unfinished basement, measuring 3,800 square feet. The home had moderate radon levels (avg. 3 pCi/L), and the client opted for proactive mitigation.

Key factors in the job included:

• Crack sealing throughout the basement floor

• A sump pump that the client’s plumber will seal after our installation

• No existing water guard system

• Clean, open access to install a seamless system without added extraction points

This installation prioritizes long-term safety with future-proofing for possible basement finishing. With structural integrity and air quality top-of-mind, this Ridgefield home is now ready for peace of mind.

This 1992 Ridgefield home tested at 14.5 pCi/L, prompting the homeowner to act fast before listing the property. The existing radon system — a one-pipe setup with an RP265 fan — wasn’t cutting it.

We tackled the problem by adding a second extraction point inside the living space, cleaning out the existing suction point, and replacing the outdated fan with a newer model. With no encapsulation required and a sealed sump pump already in place, this upgrade prepped the home for a smoother real estate process.

This cinder block home in Redding, CT had a two-pipe radon system and a radon level of 6.5 pCi/L, but the setup needed refinement. One extraction point in the back was covered with plastic, and a third pipe was necessary for full coverage. We also encapsulated a 12x42 section of crawl space to complete the mitigation. Per the client’s request, we moved the system from the front to the back of the home, avoiding the left side bedrooms. No one was home during install—check was left inside, and the homeowner is expected to email location details. Techs were advised to check with Mel for any last-minute notes before starting.
