Radon Mitigation in Rapid City Rooted in Pennington County

Dave Harlan founded Rapid City Radon Pros after seeing how radon affects homes across Rapid City, especially older stock in Downtown and Westside neighborhoods where basements meet the county's variable soil conditions. Drawing on his local roots, he built the company to deliver straightforward radon testing and mitigation that fits the realities of Pennington County living, from Rapid Valley properties to homes in Box Elder.

The work here changes with the seasons. Frequent wind and cold winters push radon entry points in foundations, while warm summers affect how systems vent through the Black Hills terrain. Rapid City Radon Pros handles these conditions directly in North Rapid, South Rapid, and nearby Summerset and Sturgis, focusing on practical fixes rather than one-size solutions.

As an owner-operated business, the team stays hands-on with every job, providing upfront quotes and clear explanations so homeowners can inspect the workmanship themselves.

I started Rapid City Radon Pros after seeing radon issues in the older homes around Downtown Rapid City and Westside where I grew up. With roots in Pennington County and time spent in Rapid Valley, I knew the continental climate with cold winters and frequent wind called for systems that hold up in North Rapid and South Rapid basements. We handle radon mitigation and radon testing for clients from Box Elder to Summerset and Sturgis because the terrain and soil conditions here change how we seal every job. You can find us Mon–Fri 8am–6pm, Sat 9am–2pm.
