About Rapid Radon Relief
Rapid Radon Relief is a veteran-owned, locally owned radon mitigation company serving the Denver area from Thornton. It tests, inspects and installs hundreds of mitigation systems a year, using installers certified through the National Radon Proficiency Program, and it is fully insured. Systems come with a 10-year warranty on the fan and a lifetime warranty on the system, and the company guarantees the new system will bring radon well below the EPA guideline of 4 pCi/L.
