Protecting Family Health: Radon Mitigation for a Multi-Generational Home

When Kathy built her home in 1993, radon wasn’t on her radar. But after her husband’s passing in 2017 and with her son now living in the basement, she wanted to be sure her home’s air was safe. A mid-June charcoal test showed radon levels at 6.5 pCi/L; above the EPA action level of 4.0, which meant it was time to take action.

Our team designed a single-point sub-slab depressurization system, using the existing sump basin in the southwest corner of the basement as the extraction point. We sealed the sump with a new airtight lid and planned the exhaust routing to exit either out the back or west side of the home, minimizing both visual impact and piping length. A 16x20 BEZ air cleaner was also installed in the HVAC system to help improve overall indoor air quality. With this tailored radon mitigation setup, Kathy’s home now has a long-term solution to reduce radon levels, protect her family’s health, and ensure safe air for years to come.
