Radon Mitigation in El Paso County, Colorado

El Paso County is Colorado's most populous county and one of its most thoroughly documented radon markets. El Paso County Public Health places the county in EPA Zone 1 and reports that over 40 percent of homes tested between 2005 and 2023 exceeded the EPA action level of 4 pCi/L. From Colorado Springs out to the plains and up the Front Range foothills, we connect county homeowners with independent, Colorado-licensed radon mitigation contractors for free written quotes.

The geology under the county

Radon is the decay product of natural uranium in rock and soil, and the Colorado Geological Survey notes it occurs in all parts of the state. El Paso County's western edge climbs into the Pikes Peak massif, and the USGS identifies weathered Pikes Peak granite as a source of uranium and its decay products. The rest of the county, from the Palmer Divide down the Fountain Creek valley and east across the plains, is built largely from sediment shed off that granite over millions of years. Soil gas moving through this material enters homes through slab cracks, joints, sumps, and crawlspace soil, and winter heating pulls it in harder.

A county of every housing era

Mitigation contractors here work the full American housing timeline in a single service area: Victorian and resort-era foundations in Manitou Springs, postwar ranches in Security-Widefield, master-planned production homes in Briargate, new subdivisions in Falcon, and rural acreage around Peyton and Black Forest. The system design changes with the foundation, but the sequence never does: test, quote in writing, install, retest to prove the drop.
