Radon Mitigation Systems in Colorado Springs
A radon mitigation system is the fix for an elevated radon reading, and Colorado Springs homes need that fix more often than most. El Paso County Public Health reports that over 40 percent of homes tested in the county from 2005 to 2023 came back above the EPA action level of 4 pCi/L. We connect you with an independent, Colorado-licensed mitigation contractor who designs the right system for your foundation and proves it worked with a retest. The quote is free and carries no obligation.
What a mitigation system actually does
Radon enters from the soil, not from building materials, so the system attacks the soil side of the equation. A pipe sealed into the ground beneath your foundation and a continuously running fan create a slight vacuum under the slab. Soil gas that would have seeped through cracks, joints, and utility penetrations gets captured and vented above the roofline instead, where it disperses harmlessly. The approach is called active soil depressurization, and it is the method the EPA describes for existing homes.
Why homes here need it
Radon is produced wherever uranium in rock and soil decays, and the Colorado Geological Survey notes it is found in all parts of Colorado. The Pikes Peak region sits against a massive granite body, and the USGS identifies weathered Pikes Peak granite as a source of uranium and its decay products. Winter makes it worse: closed-up houses and warm rising air pull soil gas indoors, which is why area health officials push testing in the cold months. Whether your home is a 1950s ranch in Security-Widefield or a 1990s two-story in Briargate, the soil under it speaks the same geology.
System types contractors install here
Active sub-slab depressurization
The standard fix for basement and slab homes. The contractor cores a hole in the slab, seals a suction pipe into the soil beneath it, and runs a continuous inline fan that vents soil gas above the roofline before it can enter the house.
Sump-based systems
Homes with a sump pit already have a route into the soil under the slab. The contractor seals the pit with an airtight lid and pulls suction through it, which often reaches the drain tile loop around the whole foundation.
Crawlspace membrane systems
Crawlspaces get a heavy plastic membrane sealed across the exposed soil, with the suction pipe drawing from beneath the membrane. This approach, called sub-membrane depressurization, treats the crawlspace like a sealed slab.
Slab-on-grade routing
Newer slab-on-grade homes without basements still draw radon through slab cracks and utility penetrations. The contractor picks a suction point near the slab center or a garage chase and routes the vent pipe up an exterior wall or through the attic.
What the contractor does, step by step
- 1
Diagnostic visit
The contractor inspects your foundation type, looks for existing test results, and checks slab openings, sumps, and crawlspaces to plan suction points.
- 2
Written quote
You get a written, itemized quote for the system design that fits your home. Nothing starts until you approve it.
- 3
Installation
Most single-family installations finish in one visit. The contractor seals accessible entry routes, sets the suction point, runs the vent pipe, and mounts the fan.
- 4
System labeling and manometer
A pressure gauge on the pipe shows at a glance that the fan is pulling. The contractor labels the system and walks you through what to watch.
- 5
Post-installation retest
A follow-up radon test confirms the level actually dropped. Keep the result: Colorado sale contracts now ask sellers to disclose known radon records.
What moves the price
Every quote reflects the same handful of variables: foundation type and how many separate slab or crawlspace zones need suction, how far the vent pipe has to travel to clear the roofline, whether the run can hide in a garage or attic, fan size for the soil under your home, and how much sealing the entry routes need. That is why a written quote from a licensed contractor beats any number you find online. For what Colorado state sources publish about typical ranges, read our radon mitigation cost guide.
