From Surprise to Solution: Tackling High Radon in a Home with Additions

After 15 years in their home, this family was shocked when a radon test revealed fluctuating levels between 10–25 pCi/L—despite having a passive system. Their children’s bedrooms are in the lower level, so health concerns were top of mind. The homeowner had already taken initiative by adding a fan to the passive system, but discovered it wasn’t addressing two key radon chambers in the home’s large rear addition.

Radon Defense Midwest stepped in to design a two-point mitigation system for the addition, along with an ERV for improved air circulation. With thoughtful placement and homeowner collaboration, this project reflects what’s possible when experience, concern, and the right team come together.

This client has just purchased a new home and wanted to ensure that it was free from any potential health hazards. He contacted Radon Defense Midwest and had a mitigation system installed since he realized what radon can do to the body. The team was efficient and professional, and the client was happy to see the radon levels drop to safe levels.

The client was well aware of radon and is scared by its future effects if left uncontrolled. So he made the decision to test, mitigate and contact his local radon mitigation specialists (us). We were able to explain how the installation process would be and he agreed to it. We were able to install a single-point system around the eave with a sub-slab extraction point. 

Andrew and Jordan did a great job with this encapsulation and mitigation system. 

Lakefront Log Cabin Gets Discreet Radon Mitigation Without Sacrificing Aesthetic

Tucked away at the bottom of a steep gravel drive, a beautiful two-story log cabin overlooking the lake was experiencing elevated radon levels of 11.6. With no warranty on levels and a fully finished basement, the homeowner took proactive steps to ensure the safety of the space. A single sub-slab extraction point was installed in the HVAC room, with careful planning around washer/dryer placement to maximize effectiveness. The system was routed discreetly—cored through the poured wall and run behind exposed exterior logs to preserve the cabin’s rustic charm. Though no one was home during the installation, everything was carefully coordinated. The homeowner also invested in a 20x25 BreatheEZ filter and UVC light system for their primary residence in Des Moines.
