Radon Mitigation Cost in Colorado Springs
Here is the honest version of the Colorado Springs radon cost question. The only dollar figures on this page come from the Colorado Department of Public Health and Environment, the state agency that runs Colorado's radon program, retrieved July 2026. No made-up local averages, no numbers recycled from other lead sites. El Paso County homeowners face this cost more often than most: El Paso County Public Health reports over 40 percent of county homes tested from 2005 to 2023 exceeded the EPA action level.
What the State of Colorado publishes
| Item | Published cost | Notes |
|---|---|---|
| CDPHE free radon test kit | $0 | One per household per year, while supplies last, through the state program. |
| Retail do-it-yourself test kit | About $10 to $50 | CDPHE’s published range for store-bought kits. El Paso County Public Health also sells kits at its laboratory. |
| Typical mitigation system, existing single-family home | About $1,300 to $3,000 | CDPHE’s published statewide range for traditional systems on existing homes. Your written quote is the real number. |
| Low-Income Radon Mitigation Assistance | Reduced or no cost | A CDPHE program for homeowners who qualify; the state reports mitigating over 200 homes through it in 2025. |

What moves a Colorado Springs quote inside that range
- Foundation zones. A single slab is the simple case. A basement plus a garage slab plus a crawlspace addition means multiple suction points or membrane work, and that is the biggest cost driver in this region's mixed housing stock.
- Vent routing. A straight shot up through the garage or attic costs less effort than an exterior run that has to clear rooflines and eaves on a two-story.
- Fan sizing. Tight soils and deep foundations can need stronger fans. The contractor sizes this from the diagnostic visit, not from a brochure.
- Sealing work. Older slabs in places like Security-Widefield or Manitou Springs accumulate cracks and open joints that need sealing for the system to pull effectively.
- Crawlspace membranes. Sub-membrane systems add material and labor compared to drilling one hole in a slab.
What a real quote includes
A written quote from a licensed contractor should name the suction point locations, the vent route, the fan model, included sealing, the post-installation retest, and warranty terms. Colorado requires the person doing this work for hire to hold a state Radon Mitigation Professional license through DORA, and CDPHE recommends getting multiple bids. Our license verification guide shows how to check any name in under a minute.
Start with the free part
Testing tells you whether you need to spend anything at all. CDPHE offers free kits, one per household per year, and El Paso County Public Health sells kits at its laboratory at 1675 W. Garden of the Gods Road. If the result comes back at or above 4 pCi/L, the quote itself is also free: we connect you with an independent, Colorado-licensed contractor serving El Paso County and Teller County, and you decide from there. The radon mitigation page explains the systems themselves.
