Gillette, Wyoming, sits in the heart of the Powder River Basin, a region known for its coal, oil, and natural gas deposits. While the area is not widely recognized for high radon risks like parts of the Midwest or Northeast, the U.S. Geological Survey and EPA radon zone maps classify Campbell County (where Gillette is located) as a Zone 2 area, meaning predicted average indoor radon levels between 2 and 4 pCi/L. However, local geology includes uranium-bearing sedimentary layers, and homes built on or near these formations can experience elevated radon concentrations. In fact, radon tests conducted in Gillette have occasionally reported levels above the EPA action level of 4.0 pCi/L.
The real estate market in Gillette is active due to energy industry employment, with a mix of older homes (built before radon-resistant construction standards) and newer developments. Home buyers and sellers are becoming more aware of radon testing requirements, especially for real estate transactions. Mortgage lenders in Wyoming do not mandate radon testing, but buyer requests are growing. Additionally, Wyoming’s cold climate means homes are tightly sealed for much of the year, which can trap radon gas. As awareness increases, the demand for professional radon testing and mitigation services in Gillette is on the rise. Starting a radon testing business now positions you to capture this growing market.
Unlike some states, Wyoming does not have a specific state-level radon certification or licensing program for radon testing professionals. The Wyoming Department of Health does not mandate a state exam or license. However, the EPA recommends that all radon testing be performed by professionals certified by a nationally recognized program. The two main certifying bodies are the National Radon Proficiency Program (NRPP) and the National Radon Safety Board (NRSB). Obtaining certification from either organization is highly recommended to build credibility and ensure you follow standard protocols.
To operate lawfully in Gillette, you must obtain a general business license from the City of Gillette. Visit Gillette City Hall or the City Clerk’s office (or their website) to apply. You will need to register your business name (if using a DBA), provide proof of liability insurance, and pay a modest annual fee. Additionally, Wyoming requires all businesses to register with the Wyoming Secretary of State for a Certificate of Authority or for a limited liability company (LLC). For a radon testing business, an LLC is a common choice for liability protection. You must also obtain a Wyoming Sales Tax License from the Wyoming Department of Revenue, even if you provide only services; some products like test kits may be subject to sales tax.
Carry general liability insurance (at least $1 million) and professional liability (errors and omissions) insurance specific to radon testing. Homeowner associations or real estate brokerages may require proof of insurance before you test properties. You should also establish a written testing protocol that follows EPA and your certifying body’s standards (e.g., closed-house conditions, placement of devices, duration).
