Radon Mitigation for the Dinapolis' New Home: Addressing Crawlspace & Basement Risks

When the Dinapolis family purchased their new home, they were already one step ahead in protecting their investment and health. With radon levels testing between 10–11 pCi/L, and a 4-foot crawlspace accessible from the back of the house, radon mitigation was a clear next move. Thanks to Realtor Charlie Sutton, who had already helped the seller patch floors and seal visible cracks, the home was prepped for an efficient install. Our team designed a 2-point radon mitigation system, one extraction point in the basement and another in the crawlspace. We paid special attention to an old coal chute in the crawlspace, sealing it thoroughly to reduce radon infiltration. This approach provided a cost-effective radon reduction solution tailored to the home’s layout; giving the Dinapolis family peace of mind from the start.

Mitigating a Family Home with History

This ranch home tested at 11.5 pCi/L, and while the structure holds decades of family history, it also presents unique challenges. The original porch was enclosed to create a finished living space, but the crawlspace beneath remains inaccessible—making radon level warranties difficult.

The basement is mostly finished, except for a small HVAC room. The homeowner’s grandfather added the basement in the 1970s and later installed interior drain tile, though the sump pump is located outside. With uncertainty about where the tile runs, our team plans to extract near the plumbing stack and tie into the system if accessible.

Routing will go through the rim joist, with the homeowner assisting by relocating the water softener basin ahead of time.

This nice couple was starting their own family and just purchased their very own home. They called in for a FREE estimate and upon seeing the house, it was a large home with a big basement storage room. They did emphasize that's where they want the installation structure to pass going up to the garage. The team drafted their request and immediately had it done! We also had company -- the Annabelle Doll! Everything went well.
