source → Get a Free Quote Credentials & details → How much does radon mitigation cost in Denver, Colorado? Based on 24 verified paid-installation prices from 3 different Colorado-credentialed contractors serving the Denver metro (2018-02 through 2025-06), the median price was $1,012, with a range of $799–$1,800. This is drawn from customer-reported prices on Angi and HomeAdvisor, not contractor-advertised “starting at” quotes, and is only published because it clears our own bar of 5+ prices from 3+ contractors — most Colorado metros don't clear that bar yet and we don't publish a number for those. What changes the price →
Source: customer-reported prices on Angi and HomeAdvisor, counted by RadonScout (see the price panel above). Does a radon contractor need a license in Colorado? Yes. Since July 1, 2022, all radon measurement and mitigation in Colorado must be done by a professional licensed through DORA's Office of Radon Professionals. Measurement licenses start RME- and mitigation licenses start RMT-.

Since Aug. 7, 2023 (SB23-206), home sale contracts carry a radon warning, sellers must disclose what they know, and CDPHE's radon brochure is required for sales and rental agreements.
Source: SB23-206 ; CDPHE, Radon and real estate . Checked 2026-11-05. Do new homes in Denver have to be radon-resistant? Not under state law: Colorado has no statewide building code, so it depends on your local code. Boulder, Longmont, Louisville, Erie, Superior and unincorporated Boulder County require radon-resistant construction in new single-family homes, and a trade-group list (as of Sept. 2021) names about 40 cities and 19 counties with a radon appendix. Check with your building department.

EPA recommends fixing a home at 4 pCi/L or higher and suggests considering a fix between 2 and 4 pCi/L. What your test number means →
