Radon Mitigation in Monument, Colorado

Monument sits high on the Palmer Divide at the north end of El Paso County, a town that began as a railroad stop in 1872 and incorporated in 1879. Today it anchors the Tri-Lakes area between Colorado Springs and the Douglas County line, and its homes sit directly on the granite-derived terrain that makes this county a radon hot spot.

No agency publishes a Monument-only radon number, so the honest yardstick is the county figure below. We connect Monument homeowners with independent, Colorado-licensed mitigation contractors for free written quotes.

Why radon collects under Monument

Radon is produced by the decay of natural uranium in rock and soil, and the Colorado Geological Survey notes it occurs in all parts of Colorado. The Palmer Divide country around Monument is built from sediment shed off the Front Range, and the USGS identifies weathered Pikes Peak granite as a source of uranium and its decay products. Soil gas moving through that material collects under tightly built homes, especially in winter when heated indoor air pulls air up from the soil.

Local housing and what it means for mitigation

Monument pairs a small 19th-century rail-town core with the subdivisions that arrived as the Tri-Lakes area grew in recent decades. For mitigation, the split matters less than the foundation under each house: homes with basements typically take a sub-slab suction point and a vent run to the roofline, sump-equipped homes can often use a sealed sump lid as the suction route, and slab or crawlspace sections get their own treatment. A licensed contractor confirms the layout during the diagnostic visit.

Verify Your Contractor's Colorado Radon License

Since July 1, 2022, Colorado law has required anyone performing radon measurement or radon mitigation services for hire to hold a state license through the Department of Regulatory Agencies' Division of Professions and Occupations. The requirement was created by House Bill 21-1195. Before you sign anything, check the license and ask these three questions. A licensed contractor will welcome all of them.

  1. 1 May I see your current Colorado radon license number?
  2. 2 Is the person doing the work the licensed individual?
  3. 3 Will you retest after installation to confirm the reading dropped?

Monument Radon Questions

Is radon worse in Monument than in Colorado Springs?

No primary source publishes a Monument-specific average, so no one can honestly claim the town runs higher or lower than the city. What is documented: over 40 percent of El Paso County homes tested from 2005 to 2023 exceeded the EPA action level, per El Paso County Public Health, and that county figure is the right planning assumption for Monument.

Does the Palmer Divide elevation change how a system is installed?

The mitigation method is the same active soil depressurization used across the county. What changes on the Divide is winter: long heating seasons strengthen the stack effect that pulls soil gas indoors, which makes the post-installation retest an important confirmation that the system handles worst-case conditions.

Where can Monument residents get a radon test kit?

El Paso County Public Health sells test kits at its laboratory at 1675 W. Garden of the Gods Road in Colorado Springs, and CDPHE offers free kits, one per household per year, while supplies last. For a real estate transaction, a licensed measurement professional provides a defensible 48-hour monitor test.
