Custom Radon Mitigation for Older Homes with Limited Crawlspace Access

After years of home additions and changes, a couple decided it was time to address radon concerns and improve comfort where they sleep. Access to parts of the basement was limited, but a plan was crafted to make the most of the available entry points. A radon extraction point was installed through a storm door addition, and a second point was cored through a basement wall to reach a crawlspace beneath the master bedroom. Extra insulation was added to the rim joists in this area, helping to create a warmer, healthier environment where they spent much of their time. Despite the home’s complex layout and hidden crawlspaces, the custom mitigation solution provided peace of mind and noticeable improvements in air quality.

A Radon Mitigation Story of Health and Safety

After losing her husband to lung cancer, this homeowner became deeply aware of the risks associated with radon exposure. When testing revealed high radon levels in her rental property, she knew action was needed to protect future tenants. Between renters, she took the opportunity to prioritize safety by scheduling radon mitigation. Knowing her efforts could prevent another family from facing the devastating effects of radon brought her peace of mind. For her, mitigation wasn’t just a precaution; it was a meaningful step in creating a safer, healthier space for others. Her story is a powerful reminder of radon’s silent danger.

This project is a single point system on front corner of the house with a second sump pit that needs to be covered in Plexi in the garage. The sump inside the house is tucked away in a piece of furniture that the client built. The exit point needs to be no higher than 30 inches and under the wood to the furnace to tuck it away from the wall. Can come out as close as possible to the soil line. Mainly, the client just wants it to be hidden inside as much as possible without having to rebuild anything int he future.
