Maine Radon & Water Treatment Before & After Photos

A rental property in Windham, Maine needed radon mitigation after an initial test showed levels as high as 93. The homeowner, preparing to lease the space, contacted Maine Radon and Water Treatment for a solution based on their reputation for straightforward, effective installs. Our team designed and installed a sub-slab depressurization system with a premium radon fan, including pressure field extension testing to ensure full coverage. We added critical upgrades like a fan moisture guard, critter guard, audible alarm, and a 50-foot fan extension to protect the system and ensure long-term performance. With the system in place and the manometer reading steady at 1.1, the home is now safer for tenants. Renting out a home? Make sure it’s protected—schedule your radon mitigation quote with MR today.

In Windham, Maine, a homeowner with a passive radon system wanted to take the next step in protecting their indoor air by activating the system after discovering alarmingly high radon levels between 50–60 pCi/L. They turned to Maine Radon and Water Treatment for their expertise in retrofitting and enhancing existing systems. The team assessed the current setup, reconfigured the PVC layout, and installed a premium RP-145 radon fan connected to existing wiring. To extend system life and ensure reliability, they added a fan guard moisture kit and an audible alarm to alert the homeowner in case of system failure.

Before:

Jason, a real estate agent in Windham, Maine, contacted us after a radon test in a 2001-built home came back at 13 pCi/L. The property had a full poured-concrete basement with bulkhead access and windows on two sides, and the exposed conditions along part of the foundation added complexity to the planning.

During evaluation, we noted approximately 20 feet of exposed perimeter drain, which required additional protection to ensure a proper and durable installation.

After:

We installed a sub-slab mitigation system designed around the structure and added a trench guard along the exposed perimeter drain to maintain airflow integrity and protect the system. The piping was routed cleanly, the installation blended well with the home, and the system delivered effective radon reduction.

The result was a professional, well-executed solution that kept the real estate timeline on track and provided confidence to everyone involved.

Another Windham home protected — and another smooth transaction supported with the right plan and execution.

Corrine S. in Windham, Maine already had an older water softener in place, but it was no longer addressing the full range of water quality issues in the home. Testing showed elevated iron levels, which were contributing to rust staining, along with a low pH of 6.51, meaning the water was slightly acidic and potentially harder on plumbing fixtures over time.

After reviewing the results and discussing long-term goals, we replaced the outdated system with a new 10" x 54" Evolve CR-100 system with Vortech tank and sweat jacket, along with a 4.5" x 20" sediment filter cartridge kit for additional filtration and protection.

The upgraded system was designed not only to soften the water, but also to raise the pH into a healthier range and reduce iron-related staining and discoloration throughout the home. Corrine also received a lifetime warranty service contract, giving her long-term support and peace of mind moving forward.

Now the home has cleaner, better-balanced water with modern equipment designed to improve water quality, reduce rust issues, and help protect plumbing and fixtures for years to come.

Sarah S. in Windham, Maine wanted to address elevated radon levels in a home designed as a mother-daughter suite, where the layout created a few unique challenges for system design. Testing showed radon levels at 5.0 pCi/L, above the EPA recommended action level, making mitigation the right next step for improving indoor air quality.

During planning, we found that connecting both sides of the home into a single extraction layout would be difficult because a guest bedroom sat directly between the ideal extraction point locations. Rather than force a less effective design, the homeowner decided to move forward with mitigating one side of the property for now, with the ability to evaluate additional options later if needed.

Our team designed the system around the accessible side of the home to create an efficient and practical solution while respecting the existing layout and living spaces.

Every home presents different challenges, and sometimes the best solution is a phased approach that balances effectiveness, design limitations, and homeowner goals.
