Radon Mitigation in Colorado Springs, CO

The standard fix for a Colorado Springs home with a basement or slab-on-grade foundation is sub-slab depressurization. A suction point is cut through the concrete slab, 3-inch PVC runs from that point up through the house or along an exterior wall, and a radon-rated fan pulls soil gas out from under the slab and vents it above the roofline. The pressure difference means radon takes the pipe instead of the cracks in your foundation.

A complete install usually takes a single day. CDPHE puts the typical Colorado cost at roughly $1,200 to $2,500, with around $1,500 being the most common all-in figure. Operating cost runs a few dollars a month in electricity.

A proper install includes a post-mitigation retest, normally a 48 to 96 hour measurement confirming the level dropped below 4 pCi/L, and a written guarantee tying the price to that result. If a bid does not mention the retest, ask why before you accept it.

What pushes the number up: crawl space work, homes with more than one foundation type, long horizontal pipe runs, finished ceilings with no clean path for the pipe, and exterior routing that has to satisfy an HOA architectural committee.

What brings it down: an unfinished basement with open joists, a straightforward exterior wall route, and a home built after about 2000 that already has a passive radon stack roughed in and only needs a fan added.
