Radon Mitigation for Colorado Homes — Outlaw Radon

Step 1

Get your number
Send us your test result — from a DIY kit, a home inspection, or a real estate transaction test. We don't perform testing ourselves, so there's no incentive to talk up a number.

Step 2

Diagnose
If it's above the EPA action level, we walk the foundation to find how gas is getting in, and size a system for that specific house.

Step 3

Mitigate
A sub-slab depressurization system is installed and vented above the roofline, then verified with a follow-up test to confirm the number dropped.

Step 4

Ready when you are
Most systems are quoted within a day or two of sending your results. Breathe easy, live safe.

What is radon, and why does it matter here?

Radon is a colorless, odorless radioactive gas that forms naturally when uranium in soil and rock breaks down. It seeps up through the ground and can build up inside homes through foundation cracks, sump pits, and other small openings — completely undetectable without a test. The EPA calls it the second-leading cause of lung cancer in the U.S. overall, and the leading cause among people who’ve never smoked, estimating it contributes to roughly 21,000 lung cancer deaths every year. Nationally, about 1 in 15 homes has an elevated level — in Colorado, that number runs far higher.

Nearly every county in Colorado, Weld and Larimer included, is rated EPA Zone 1 — the agency’s highest radon-potential category. Larimer County’s own health department reports an average indoor radon level of 7.8 pCi/L, nearly six times the national average of 1.3 pCi/L. None of that means your specific house has a problem — only a test can tell you that — but it’s why testing matters more here than in most of the country.

Zone 1

Milliken and most of Northern Colorado sit in the EPA’s highest radon-potential category.

4.0 pCi/L

The EPA’s recommended action level. Above it, mitigation is worth doing — below it, we’ll tell you that too.

90%+

Typical radon reduction from a correctly designed mitigation system, verified with a post-install test.

Services

Three things we install and service, all aimed at keeping soil gas and groundwater out of your living space.

Radon Mitigation

Sub-slab depressurization systems sized to your foundation and soil.

Sump Pumps

Installation and service for sump pits — a common radon entry point and a water-management necessity.

Crawlspace Ventilation

Sealed vapor barriers and mechanical ventilation for crawlspace foundations.

Why "Outlaw"

The radon industry runs on fear — inflated readings, systems sold to houses that don’t need them, and quotes that change depending on who answers the phone.

We only do mitigation, and we don’t test. That means we never have an incentive to talk up your number, because we’re not the ones who measured it. Bring us your result, and we’ll give you an honest read on whether a system is worth installing — and a fair quote if it is.
