How we review listings

We list companies that offer radon testing or mitigation in Colorado. Before a listing is marked verified, we confirm the business is active, check its Colorado radon license and NRPP or NRSB certification for the people doing the work, and confirm the phone number and service area.

Featured placement is labeled as featured. Payment does not change a company's certification status or reviews.
