About Us | Badlands Radon

Your Local Radon Experts in the Black Hills

Badlands Radon is a licensed and insured radon mitigation company proudly serving Pennington County and the entire Black Hills region. We are committed to one thing: making your home safe from the invisible threat of radon gas.

South Dakota has the highest average indoor radon levels in the entire United States, with a statewide average exceeding 9 pCi/L — more than double the EPA action level of 4 pCi/L. Rapid City and Pennington County are no exception. The geological makeup of the Black Hills, rich in uranium-bearing granite, makes radon a serious concern for every homeowner in our region.

Radon is the second leading cause of lung cancer in the United States. It is a colorless, odorless radioactive gas that seeps into homes through cracks in foundations, gaps around pipes, and sump pits. Without proper testing and mitigation, elevated radon levels put your family at risk every single day.

Our team brings hands-on expertise and a deep understanding of local building conditions. Every mitigation system we design is custom-fitted to your home's foundation type and radon concentration level. We use proven sub-slab depressurization technology to reduce radon levels to well below the EPA action level — and we guarantee our results.

Whether you need a professional radon test, a full mitigation system installation, or a fan replacement for an existing system, we are here to help. We offer free estimates, transparent pricing, and same-day service availability for urgent situations.

Local Expertise

Based right here in the Black Hills. We understand the unique geology and radon challenges that affect homes in Pennington County and western South Dakota.

Serving the Black Hills with Expertise and Integrity

South Dakota's radon problem is severe and well-documented. The state consistently ranks first in the nation for average indoor radon concentrations, driven largely by the uranium-rich granite and schist that underlies much of the Black Hills region. Pennington County — home to Rapid City — sits directly on some of the most radon-prone geology in the country. This isn't a regional concern that might or might not affect your home; it's a near-universal risk for the area.

Badlands Radon was founded specifically to address this problem in the communities where we live and work. Our team has seen the full spectrum of radon challenges in Black Hills homes — from newer construction on slab foundations to older homes with block basements, from single-system solutions to complex multi-point installations for large or complicated structures. Every home is different, and we design every system to match the specific conditions we find.

When you work with Badlands Radon, you get more than a contractor who shows up and drills a hole. You get a certified professional who will explain what we found, why we're recommending a specific approach, and what you can expect from the system long-term. We believe informed homeowners make better decisions, and we take the time to make sure you understand the process from start to finish. Call (605) 640-5642 for a free estimate today.
