New Construction Radon Systems, Pueblo & Pueblo West

The Cheapest Radon System Is the One Poured Into the Foundation

Retrofit mitigation means coring concrete, snaking pipe through finished space, and working around drywall. A rough-in during construction skips all of it: a gas-permeable gravel layer or a soil-gas collector mat under the slab, a tee and a vertical run of PVC stubbed up through the framing before the roof goes on, sealed penetrations, done. The incremental cost is a few hundred dollars on a build where everything else costs five figures.

Here's the honest part most builders don't say out loud: a passive stack alone doesn't always win in a Zone 1 county. Thermal stack effect moves some gas, but Pueblo soil can out-produce it. The play is passive now, test after occupancy, and if the number comes back high, a fan drops into the existing pipe in about an hour, with the wiring already waiting in the attic because we rough that in too. Owner never sees a pipe run through their new living room either way.

For Builders and Owner-Builders

We work with builders on single customs and full filings out toward Purcell and the newer Pueblo West subdivisions. You get: mat or gravel-loop layout matched to your foundation plan, rough-in at the right stage so we're never holding up your pour, labeled stub-outs your inspector can sign off at a glance, and post-occupancy testing offered to your buyers under your name or ours, your call. One custom builder we work with puts our retest report in the closing folder for every house, it's become part of his sales pitch.

Building on a crawl space design? The same logic applies with a membrane instead of a mat, see our crawl space page, and doing it before the subfloor goes down is a gift to everyone involved.

Pouring a foundation soon? Call (719) 355-3733 before the gravel goes down, the phone call is free and the timing matters.
