Radon Mitigation Systems for Colorado Homes
What installation day actually looks like
Four steps from first call to a verified low reading.
Step 1
Free assessment & quote
We review your test results and foundation type, then send a written quote — no obligation, no pressure visit.
Step 2
System design
Suction points, pipe routing, and fan placement get mapped to your specific slab, soil, and layout.
Step 3
Installation day
Most systems go in within a single day, with minimal disruption to the house or your schedule.
Step 4
Verification test
A follow-up radon test confirms the number actually dropped before we call the job done.
How our radon mitigation systems work
Sub-slab depressurization — a suction point, a pipe, and a fan — is the standard, effective fix for slab-on-grade and basement foundations.
Sub-slab depressurization
Suction points beneath the slab, routed to an exterior vent, sized to your soil and layout — the standard fix for slab-on-grade and basement foundations.

Have a sump pit or a crawlspace? See our dedicated Sump Pumps and Crawlspace Ventilation pages — both often get combined with a mitigation system in the same visit.
- Sealing — Cracks, sump pits, and wall-floor joints get sealed as part of the system, not left as a gap in it.
- Fan selection & routing — Fan strength and pipe routing are chosen for your soil and layout — oversized systems just waste electricity and add noise.
Free RadonAway radon alarm
Included at no extra charge with every complete system installation — a continuous digital monitor so you can see your number, not just trust that the fan is running.
New construction
Building in Weld or Larimer County? We consult on radon-resistant design during framing — a passive vent stack and sealed slab penetrations — far cheaper than retrofitting later.
- Design review — Vent stack placement and slab penetration plan, reviewed against the foundation drawings.
- Rough-in inspection — On-site check before the slab is poured or the crawlspace is closed up.
- Baseline test — A test once the home is occupied, to confirm the passive system is working — or needs a fan added.
How to know your system is working
Every system we install has a small pressure gauge, usually a U-tube manometer, mounted right on the pipe. A steady reading means the fan is running and pulling suction from beneath your slab as designed. If that gauge ever reads flat, or the liquid column drops to the bottom, it’s usually the simplest sign the fan has stopped — worth a call regardless of who installed the system. Beyond the gauge, you can listen: a working fan makes a quiet, continuous hum, and a system gone silent is a system that’s stopped protecting your home.
We also run a follow-up radon test after every install, included in the job, to confirm your number actually dropped — not just that the fan is spinning. Most systems bring a home from well above the EPA’s 4.0 pCi/L action level down to a fraction of that. If you want extra peace of mind down the road, retesting every couple of years is a reasonable habit, especially after any remodeling, foundation work, or new cracks in the slab.
