About Grand Junction Radon

Radon Is Personal Here

Grand Junction Radon is a local radon testing and mitigation company serving Grand Junction and the wider Grand Valley. We focus on one thing — getting the radon out of the air your family breathes — and we do it to the standards the state of Colorado and the national radon codes require. If you've just opened a high test result and your stomach dropped a little, you're in the right place. We've walked a lot of homeowners through exactly that moment, and it is almost always more fixable than it feels.

There aren't many places in America more radon-aware than the Grand Valley. Mesa County sits in EPA Radon Zone 1, the highest of the three national zones, and roughly a third of the local homes tested through the state program come back at or above the 4.0 pCi/L action level. Statewide, the Colorado Department of Public Health and Environment reports that about half of Colorado homes test above that line. This isn't a sales pitch — it's the geology of the Colorado Plateau, and it's the reason radon has been part of the conversation in this valley for generations.

Licensed, Certified, and Held to a Standard

Colorado has required radon measurement and mitigation professionals to be state-licensed since July 1, 2022, through DORA — the Department of Regulatory Agencies and its Division of Professions and Occupations. That matters. It means a radon company in this state isn't operating on good intentions alone; it's accountable to a licensing framework built around the national ANSI/AARST consensus standards and NRPP/NRSB certification. We build every system to those codes, pull the building and electrical permits the work requires, and document what we do.

We say this plainly because not every outfit working the valley holds that line. When you're deciding who to let put a permanent system on your home, "licensed Colorado radon professionals, built to AARST standards" is a fair and specific bar to hold anyone to — including us.

What "held to a standard" looks like on your house:

• Diagnostics first. We check sub-slab communication and find the right suction point so the system is sized correctly the first time.
• Permitted work. Piping, penetrations, and the electrical connection are done to code and inspected.
• Documentation. You get a record of your radon level before and after — useful for your peace of mind and for a future sale.

Why We Always Test After We Mitigate

A radon system that isn't verified is just a pipe and a fan. The only way to know a mitigation actually worked is to test the air again after it's running — a post-mitigation verification test. We include that step on every job, because a guarantee that your level will land below 4.0 pCi/L means nothing unless we're willing to measure and prove it. If a system doesn't get you there on the first pass, we adjust it until it does. That's the whole promise: not "we installed something," but "your number came down, and here's the proof."

What We Stand For

• Prove the fix, every time. Every mitigation ends with a verification test and documentation you can keep.
• Firm pricing, no pressure. You get a written price before any work starts — and an honest answer about whether you even need us.
• Built to code. Licensed Colorado work, ANSI/AARST standards, permits pulled and inspected.
• Real-estate ready. Under contract with a high result? We schedule fast and coordinate with your agent so the deal stays on track.
• Local and straight with you. We work the Grand Valley every day and we'd rather tell you the truth than close a sale.
