Radon Mitigation
Protect Your Home and Health
In Utah, 1 in 3 homes has elevated radon levels. The EPA recommends action for levels at or above 4.0 pCi/L. Radon is a naturally occurring, cancer-causing gas that seeps into homes through cracks, plumbing penetrations, concrete floors, heat ducts, and especially exposed crawl spaces. Free Testing for Utah Homeowners At High Mountain Mitigation, your family’s safety is our top priority. That’s why we offer free radon testing to any homeowner in Utah.
