What We Do — and What We'll Tell You to Get for Free
We design and install radon mitigation systems, perform licensed radon measurements, and repair or replace aging systems and fans — for homes across the Roaring Fork Valley and the Crystal River Valley, and nowhere else. Working one market means we know its quirks: hillside walkouts with three foundation types under one roof, rocky sub-slab conditions that punish lazy suction-point choices, design-review boards that care where a pipe runs, and second homes that sit closed for months.
Here's what we don't do: sell you a test you could have gotten for free. The City of Aspen hands out kits year-round at City Hall, Pitkin County distributes them every January, Garfield County and CLEER in Carbondale stock them year-round, and Eagle County offers them at locations including the El Jebel Community Center. If a free kit fits your situation, we'll point you there first — every time. Our job starts when the number comes back high, when results conflict, or when a real-estate deadline needs a licensed measurement that stands up. That's not charity; it's how you build a radon company people in a small valley actually trust.
Licensed — Please Go Check
Since July 1, 2022, Colorado law HB21-1195 has required anyone performing radon measurement or mitigation for hire to hold a state license through DORA, built on national NRPP certification. We don't just comply with that law — we campaign for it. Before you hire any radon contractor, including us, look them up on DORA's Check a License tool. It takes two minutes, it's public, and it instantly filters out the anyone-with-a-drill operators the law was written to stop. A contractor who hesitates when you ask for their license number has answered your real question.
Verification Testing, Always
Every installation we do ends the same way: a 48-hour post-mitigation test that produces a number, not a promise. NRPP-certified methods govern the whole job — diagnostics and sub-slab communication testing before we drill, fan placement outside the living space per code, sealed pipe runs, a manometer you can read at a glance — but the verification test is the part we consider non-negotiable. You should never have to take a contractor's word that a radon system works. Mitigated homes typically land under 2 pCi/L, often under 1, and you'll see yours in writing.
