Radon Testing in Boulder That Delivers Clear Answers, Fast

Why Boulder Residents Search for 'Radon Testing'

Boulder sits in one of Colorado's EPA-designated Zone 1 areas—meaning it has the highest potential for elevated radon levels. Radon is a naturally occurring radioactive gas that seeps into homes and commercial buildings through foundation cracks and unsealed soil contact points. You can't see it or smell it, but long-term exposure is the second leading cause of lung cancer.

Whether you're buying a home near Table Mesa, renting a basement apartment in North Boulder, or evaluating an office in Gunbarrel, radon testing gives you the knowledge you need to take action—or breathe easier.

Our Approach

Think of radon like smoke from an underground fire—you can't see it, but it can fill your house. We place a tamper-resistant monitor in the lowest livable space for 48 hours, during which time windows remain closed and normal living conditions apply.

After the test, we download the data and analyze it for peaks, fluctuations, and average exposure. We then explain what it means—and if mitigation is recommended.

How Much Does It Cost?

Radon testing is one of the most affordable risk-management tools you can get. Our rates are competitive and can be bundled with a home inspection or environmental screening package.

Frequently Asked Questions

Is radon a real concern in Boulder?

Absolutely. Boulder is in a high-risk zone, and elevated levels are common even in newer homes or well-sealed buildings.

How long does a radon test take?

Standard testing lasts 48 hours. We use continuous radon monitors to collect hourly readings over that period.

What’s considered a “high” radon level?

The EPA recommends mitigation for any reading at or above 4.0 pCi/L. However, even levels between 2.0–4.0 may justify action depending on your exposure.

Do you install radon mitigation systems?

We don’t install systems directly, but we refer licensed, experienced radon mitigation professionals and can retest after installation to confirm success.
