Spearfish is in Lawrence County in the northern Black Hills. The region's geology varies a lot from one area to the next, and radon readings vary with it. Some Black Hills homes test far above the EPA's 4.0 action level, so testing is the only way to know where yours stands.
Radon is the second leading cause of lung cancer in the US after smoking, according to the EPA, and the leading cause among people who have never smoked.
Radon in Spearfish homes
- Walk-outs and slab additions. Many homes combine a basement with slab or crawl space additions. Each area may need attention.
- Cabins and second homes. If you own a cabin in the Hills, test it too, especially if anyone sleeps on the lowest level.
- College town rentals. Landlords can test and mitigate rentals the same way as owner-occupied homes.
We also take requests from Sturgis and Rapid City.
