Why Radon Testing Matters For Every Fort Collins Homeowner

Radon isn’t something you can see, smell, or taste — but here in Fort Collins, it’s one of the most important things homeowners should pay attention to. Colorado has some of the highest radon levels in the country, and Larimer County is officially classified as an EPA Zone 1 (High Risk) area. That means radon testing isn’t just a “good idea”… it’s a must.

What Makes Radon Such A Big Deal In Northern Colorado?

Fort Collins sits on naturally uranium-rich soil. As that uranium breaks down, it releases radon gas, which can enter homes through tiny openings like:

• Foundation cracks
• Sump pits
• Gaps around plumbing
• Crawlspaces

Even brand-new homes are not immune. In fact, local data shows that roughly half of all homes tested in Larimer County exceed the EPA action level of 4.0 pCi/L. That’s why consistent testing is so important.

The EPA classifies Larimer County as an EPA Zone 1 area, meaning we are officially a High-Risk region for elevated indoor radon levels above 4.0 pCi/L. Colorado’s soil contains naturally high uranium, which is why radon is so common here.

For homeowners, testing isn’t something to put off. Many homes in Larimer County test high without any warning signs, and mitigation is simple and highly effective once levels are identified. Colorado now requires landlords and home sellers to provide written radon disclosures, reinforcing how important this issue is for families’ health and safety.

The map above shows radon test results in Larimer County. Results below the EPA’s recommended action level are shown in blue. The average radon level in the area is 7.8 pCi/L (picocuries per liter), which is higher than the national average of 1.3 pCi/L. The EPA advises that homes with radon levels of 4 pCi/L or more should have mitigation systems installed.

Are Mitigation Systems Effective?

Yes! Radon mitigation is one of the quickest and most effective home safety upgrades you can make. Most systems can reduce radon levels by up to 99%, and many Fort Collins homes already have mitigation installed.

But here’s the key: Mitigation systems still need periodic testing to confirm they’re working as intended. Fans can fail, pipes can clog, or the previous installation can be outdated.

Peace Of Mind Starts With A Simple Test

Radon testing is fast, affordable, and one of the best health-protecting decisions a homeowner can make.

If you’re buying a home, selling a home, or simply haven’t tested in the last two years, now is the perfect time.
