Licensed and insured radon mitigation professionals protecting Billings families since day one.
Rim Rock Radon was founded with a single mission: to protect Montana families from the invisible danger of radon gas. Radon is the second leading cause of lung cancer in the United States, and Yellowstone County consistently tests above the EPA action level of 4 pCi/L. We saw the need for a dedicated, reliable radon mitigation company that Billings homeowners could trust.
From the start, we committed to doing things right. Every system we install follows EPA guidelines and industry best practices. We use only proven sub-slab depressurization technology and back every installation with a performance guarantee. Our team is fully licensed and insured, and we carry the training and certifications needed to handle any residential radon challenge.
Today, we serve all of Yellowstone County and surrounding communities including Laurel, Lockwood, Shepherd, Park City, Columbus, Red Lodge, Hardin, and Roundup. We have helped hundreds of homeowners reduce their radon levels and breathe easier in their own homes.
Trusted by homeowners across Billings and Yellowstone County for reliable, guaranteed radon solutions.
Fully licensed and insured radon mitigation professionals following EPA and state guidelines for every installation.
We guarantee radon levels below 4 pCi/L after installation or we return to fix it at no additional charge.
Most radon mitigation systems are installed in a single day. Your home is fully usable immediately after.
No-obligation radon assessments. We inspect your home, explain your options, and provide upfront pricing with no hidden fees.
