Custom Radon Mitigation System Improves Health and Comfort for Longtime Homeowners

An elderly couple, married for 62 years and living in their home for over 50, became increasingly concerned about their indoor air quality — especially since they spent much of their time downstairs. A radon mitigation plan was carefully designed around their needs. A single-point depressurization system was installed, utilizing the existing sump pit in the northeast corner. Due to its irregular shape, a custom sump lid was crafted to ensure a proper seal. The radon exhaust was routed neatly through the same corner, with a soffit penetration to maintain the home’s exterior appearance. Additional crack sealing throughout the basement further strengthened the system’s effectiveness. With the new system in place, they now enjoy a safer, healthier environment for years to come.

In order to guarantee radon levels under 4.0 pCi/L we need to seal any exposed dirt in the home, like in an crawlspace. We have encapsulated this crawlspace with 20 mil plastic to prevent anything from coming through.

This customer's radon gas mitigation system has an extraction point in their sump pump. In order to effectively vent the radon gas, we redirected the flow of air around the sump pit with the sump pump and installed clean space sealant around the sump pit extraction point to direct the radon gas into the extraction point in the sump of this home.

Everything went great

Lance and Cole did a great job getting this crawlspace encapsulated and installing this radon mitigation system
