Colorado Radon Company

Colorado Radon Company tests for and mitigates radon from Denver and Westminster across the Front Range, with same-week service offered in Winter Park, Fort Collins, Denver and Castle Rock. Most systems use sub-slab depressurization, a pipe through the foundation slab connected to a continuously running fan, and the company also handles crawlspace work and radon system inspection and repair. Follow-up testing is done 24 to 48 hours after installation to confirm the reduction. It serves homeowners, home buyers and sellers, real estate agents and home builders, offers low-level guarantees and firm all-inclusive prices, and gives free estimates. Installers are certified by the National Radon Proficiency Program. Rated 4.9 from 146 Google reviews, 142 of them five stars and 3 one star.
