A radon shop for Knoxville and Knox County

We're Radon Knoxville. We test indoor air and we install the fan systems that keep soil gas from using your house as a chimney. Knoxville is home base. Knox County is EPA Zone 1. Farragut, Hardin Valley, Fountain City, Bearden, and South Knox are the same county dirt with different houses.

We care about the unglamorous parts: closed-house hours, a device that is not sitting on a dryer, a crawl membrane that is actually sealed, and a mixed foundation that gets suction on both sides.

We're not a national lead form that auctions your phone number. You talk to people who schedule tests in Knox County, design ASD systems for the foundations we actually see here, and retest after the fan is in.

Tennessee does not state-license radon work. We treat that as a reason to work to recognized national standards (NRPP and NRSB), not a reason to shrug. TDEC's free kits are a good public-health tool. A purchase contract wants a documented test and a report. Both sentences can be true.

If you have a number, a foundation type, and a ZIP, request a quote. If you want the county map, start with the Knox County service area. If you want a fake reading from a zone map, we will not give you one.
