Radon mitigation across Colorado Springs
The Pikes Peak region sits on some of the most radon-productive geology in Colorado, a state that already reports among the nation’s highest average indoor levels. Elevated results here are common rather than exceptional.
Housing spans the historic Old North End and downtown neighborhoods, vast military-adjacent development around Fort Carson and the Academy, and newer growth north toward Monument. This hub routes El Paso and Teller counties.
Radon in Colorado Springs & the Pikes Peak Region
EPA places El Paso County in Zone 1 of its Map of Radon Zones, its highest predicted category. The Front Range’s granitic, uranium-bearing soils are the reason, and Colorado’s state radon program reports that a majority of homes tested statewide come back at or above the action level. Individual homes still test the full range.
Who may do the work in Colorado
Colorado does not license radon professionals at the state level. The state radon program instead directs homeowners toward nationally certified professionals credentialed through NRPP or NRSB. Ask any bidder which national certification they hold, confirm it is current, and apply the same scrutiny to the written design, warranty terms, and whether a post-mitigation verification test is included.
Radon in a Colorado home sale
Colorado requires sellers of residential real property to give buyers a radon warning statement and the state’s radon brochure before a sale, and the standard seller’s property disclosure addresses radon testing and mitigation. Colorado does not require a seller to test or to mitigate — the response to an elevated result is negotiated like any other inspection finding.
Why results vary across Colorado Springs & the Pikes Peak Region
Colorado Springs sits at the foot of Pikes Peak, and the granite forming the mountain is itself relatively uranium-rich. The Dawson Arkose beneath much of the city is composed largely of material eroded off that granite, so the source rock and the soil derived from it share the same chemistry — an unusually direct explanation for a metro's radon. East of town the Pierre Shale produces expansive claystone; the Ute Pass fault runs along the mountain front through Manitou Springs.
Housing stock and foundations here
The city holds prewar brick and frame housing on block and stone in the Old North End and downtown, an extensive postwar ranch belt, and large tracts of 1990s-forward construction on the north and east sides. Crawlspaces are common across the older housing, and structural floors over voids appear in newer construction on expansive claystone east of the city. Monument and the northern corridor carry newer subdivisions; Manitou Springs is a compact historic town on steep ground with foundations cut into slope; Woodland Park is mountain property.
Does new construction change the answer?
Newer north-side and Monument construction mitigates conventionally where there is a basement and by membrane where there is a crawl or a structural void. The Pikes Peak granite beneath is unchanged by the build date. This market sees heavy relocation traffic — much of it military — and buyers arriving from low-radon parts of the country frequently assume a new house in a new subdivision is a low-radon house. In this region that assumption is expensive.
When to test in Colorado Springs & the Pikes Peak Region
The heating season produces the strongest stack effect and the most conservative closed-house readings. The Front Range's wide daily swings and chinook wind events move house pressure noticeably, which makes short-term results noisier here than in steadier climates — a real argument for confirming borderline numbers. During a chinook or a warm winter week, resist opening the house up mid-test.

Colorado Springs & the Pikes Peak Region questions
Which communities does this market route?
Five published city guides across El Paso and Teller counties, plus additional ZIPs — Falcon, Woodland Park, Black Forest, Security-Widefield, and north and south Colorado Springs sectors. The quote form resolves any address definitively.
We are PCSing to Fort Carson or the Academy. How fast can this be handled?
Installation is typically one working day, and the full sequence — quotes, install, verification retest — commonly fits inside a few weeks. Flag your deadline in the request so contractors with near-term availability self-select. We do not promise turnarounds on a contractor’s behalf.
Does elevation affect radon here?
Not directly. Radon comes from uranium decaying in soil and rock beneath your foundation. What matters in the Pikes Peak region is the granitic, uranium-bearing geology and how each house handles air pressure — not altitude itself.
Is a crawlspace with a plastic vapour barrier already mitigated?
No. A vapour barrier laid loose for moisture control is not a mitigation membrane — it is usually unsealed at the perimeter, unsealed at the seams, and not connected to any suction. A mitigation membrane is sealed at the perimeter, at every seam, and around every pier and penetration, with a fan drawing beneath it. The materials look similar; the installation is entirely different.
We are relocating here from a low-radon area. Is testing worth it?
Yes. Colorado reads high across most of its counties, and the Pikes Peak region has a well-understood geological reason for it. Whatever was customary where you came from, testing during your inspection period here is ordinary practice and costs little relative to the transaction. Ask for a measurement by a nationally certified professional rather than relying on a prior owner's recollection.
We are on a tight military relocation timeline. What is the fastest responsible path?
Run the confirming test and the quoting simultaneously rather than in sequence, and ask bidders for a written design based on a site visit rather than a phone estimate. Make mitigation and a post-mitigation verification test a condition of closing so the outcome is documented even if the work finishes after you take possession.
