From Rapid City out along the I-90 corridor to Sturgis, we test and mitigate on the same ground — and finish every install with a verification test. Find your town below.

Rapid City Radon serves Rapid City and the ring of communities where the Black Hills meet the plains: the I-90 corridor towns from Box Elder up through Black Hawk, Summerset, and Piedmont to Sturgis, plus Rapid Valley to the east. That coverage isn't arbitrary — it follows the rock. EPA and USGS mapping shows a ridge of high radon potential wrapping around the Black Hills, tracking the uranium-bearing granite core of the Hills, and these towns are built on and beside it.
The paperwork says Pennington County is EPA Zone 2, but state test data has shown a majority of local tests coming back above the 4.0 pCi/L action level — the reason we tell every caller, in every town, the same thing: the map is a prediction; your test is a fact. Wherever you are on the corridor, the job is identical — test to get a real number, install an active sub-slab depressurization system built to ANSI/AARST standards if it's high, and prove the fix with a post-mitigation test.
Home base. From Robbinsdale and the neighborhoods south of the hospital — both named in state test data as radon hot spots — to the streets under Skyline Drive and M Hill, out past the School of Mines and along Rapid Creek, we work Rapid City every day. The city's basement-heavy housing stock is exactly where our long heating season concentrates radon, and it's where most of our installs happen. Start with the Rapid City radon mitigation page, or go straight to testing if you don't have a number yet.
Each community below has its own radon page with local context — same standard of work, same verification test at the end. Pick your town, or just call.
Home of Ellsworth Air Force Base and one of the fastest-growing cities in South Dakota as the base expands for the B-21 mission. All that new construction in the Douglas School District area sits on the same ground as everything else here — new slabs don't get a pass on radon.
Box Elder radon →The unincorporated community just east of Rapid City carries a distinction nobody wants: state test data has named Rapid Valley as a local radon hot spot. If any neighborhood on this page should test before assuming anything, it's this one.
Rapid Valley radon →A Meade County bedroom community on I-90 between Rapid City and Summerset. Minutes from our home base, which makes quotes quick and single-visit installs easy to schedule.
Black Hawk radon →One of South Dakota's newest cities — incorporated in 2005 — and filling in fast with new construction along I-90 between Black Hawk and Piedmont. A brand-new house draws air from the same geology as a fifty-year-old one, so test it before you finish the basement.
Summerset radon →A foothills town in the Elk Creek area, tucked right against the edge of the Hills on I-90 toward Sturgis. That puts Piedmont homes on the doorstep of the high-radon-potential ground that rings the Black Hills — testing here is not optional homework.
Piedmont radon →The Meade County seat and home of the Sturgis Motorcycle Rally, about 30 minutes northwest of Rapid City. Full testing and mitigation service, rally season or not — same standard, same verification test.
Sturgis radon →Your address changes our drive time, not the work. Every job on this page gets the same treatment: diagnostics before drilling, a system built to the ANSI/AARST national standards, a firm written price before we start, and a post-mitigation test that proves the number came down. If you're still weighing it, start with your number — get a radon test, see what a system costs, and call us when you're ready for a firm quote.
