Radon Mitigation in Black Forest, Colorado
Black Forest spreads across the wooded high ground northeast of Colorado Springs, an unincorporated El Paso County community of large lots and custom homes under the pines. The same elevated terrain that gives the area its ponderosa forest also puts its homes on the granite-derived soils that drive radon across the county.
No agency publishes a Black Forest-only radon figure, so the county number below is the honest baseline. We connect Black Forest homeowners with independent, Colorado-licensed contractors for free mitigation quotes.

Radon comes from the decay of natural uranium in rock and soil, per the Colorado Geological Survey, and the sediments underlying the high ground between Colorado Springs and the Palmer Divide derive from the erosion of Front Range granite. The USGS identifies weathered Pikes Peak granite as a source of uranium and its decay products. Large custom homes with big foundation footprints have more slab area in soil contact, which is more opportunity for soil gas entry, not less.

Local housing and what it means for mitigation
Black Forest housing runs to custom builds on acreage, many with finished walkout basements, attached garages on separate slabs, and additions poured over the years. Each separately poured foundation zone can need its own suction point or sealing attention, so quotes here often hinge on how many zones the home has rather than its square footage alone. Homes on private wells should also ask their tester about waterborne radon, a separate question from soil gas.
