Certified Radon Mitigators
in Boulder, Colorado

Boulder County is one of Colorado's highest-radon jurisdictions, with Precambrian granite from the Flatirons and Front Range underlying much of the city and surrounding communities. Many Boulder homes — particularly older properties in Mapleton Hill, University Hill, and East Boulder — have never been tested despite sitting in one of the most radon-active geological zones in the country. The city's progressive building codes and green construction practices haven't reduced radon risk, which comes from soil and rock rather than building materials. Boulder residents should test before assuming lower levels.
