Radon Mitigation in Briargate, Colorado

Briargate covers the master-planned north end of Colorado Springs, developed under a 1978 master plan, annexed to the city in 1982, and built out over the decades since. Its orderly subdivisions sit on the same granite-derived El Paso County soils as the rest of the region, and orderly streets do nothing to slow soil gas.

No Briargate-specific radon average is published, so the county figure below is the honest baseline. We connect Briargate homeowners with independent, Colorado-licensed contractors for free mitigation quotes.

Why radon collects under Briargate

The Colorado Geological Survey attributes radon to the decay of natural uranium present in rock and soil throughout the state, and the USGS identifies weathered Pikes Peak granite, the bedrock mass looming southwest of Briargate, as a source of uranium and its decay products. Newer, tighter construction holds conditioned air well, and in winter that same tightness strengthens the vacuum effect that draws soil gas up through slab joints and penetrations.

Local housing and what it means for mitigation

Briargate’s housing stock tracks its build-out: production two-stories from the 1980s and 1990s alongside newer phases toward the north and east. In homes of this era with basements, mitigation is usually straightforward: one sub-slab suction point, a vent run concealed through the garage or attic where the layout allows, and sealing at the slab edges. The fan and gauge typically end up out of sight, which matters in HOA neighborhoods.
