Radon mitigation in Colorado Springs
The Pikes Peak region has an unusually direct radon story: the granite that forms the mountain is relatively uranium-rich, and much of the soil in the city is eroded from it. Mitigation here is common, well-practiced work.
The city holds prewar brick and frame housing on block and stone foundations 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. Monument and the northern corridor carry newer subdivision building; Manitou Springs is a compact historic town on steep ground; Fountain and Woodland Park are distinct in their own ways.
What mitigation involves here
The design question is almost always foundation type. A conventional basement takes conventional sub-slab depressurization. A crawlspace takes a sealed membrane with suction drawn beneath it. A structural floor over a void takes the same membrane approach in a tighter space. A house with both a basement and a crawlspace is two zones, and whether one fan can serve both depends on whether they communicate and what the diagnostic shows. Colorado issues no state radon license, so verify a current NRPP or NRSB certification before you compare anything else. Crawlspaces are common across the older housing here, and structural floors over voids appear in newer construction on expansive claystone, particularly east of the city. Basements are typical in the postwar and newer stock. Manitou Springs’ steep, narrow lots and historic housing produce foundations cut into slope with stone walls and irregular floors.
Deciding whether you need it
Whether a specific house in Colorado Springs needs a system is settled by a measurement at that address, never by a county map — EPA recommends fixing at 4 pCi/L and considering action between 2 and 4 pCi/L. Requests from El Paso route to independent businesses that hold a current NRPP or NRSB mitigation certification; because Colorado does not issue its own radon license, that national certification is the credential to verify. Colorado Springs sits at the foot of Pikes Peak, and the granite that forms 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. East of town the Pierre Shale produces expansive claystone, and the Ute Pass fault runs along the mountain front through Manitou Springs.
Who may legally do the work
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 Mitigation questions in Colorado Springs & the Pikes Peak Region
Is a crawlspace with a plastic vapor barrier already mitigated?
No. A vapor 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.
What makes mitigation different in Colorado Springs?
Newer subdivision basements are easy to route in, subject to HOA appearance rules. Older neighborhoods have usable lots and light appearance constraints. Manitou Springs and the Woodland Park area present mountain and hillside constraints — steep lots, limited exterior routing, and access that occasionally affects how materials reach the site.
Does Radon Connect do the mitigation work?
No. Radon Connect is a free referral service — it does not test, inspect, design, or install anything. Your request goes to no more than three independent businesses serving Colorado Springs, each holding a current NRPP or NRSB mitigation certification, and each quotes you directly. The contract, the price, the schedule, and the warranty are between you and the contractor you pick.
