Why Radon Testing is a Must in Fort Collins

When most people think about hidden dangers in their homes, mold or asbestos often come to mind first. But in Fort Collins, Colorado, there’s another invisible threat that often goes unnoticed—radon gas.
​
Radon is colorless, odorless, and impossible to detect without testing. Yet, it is one of the leading causes of lung cancer in the United States and is found at particularly high levels across Colorado.

​The good news? Testing is simple, affordable, and the first step toward ensuring a safe home.

Key Takeaways

• Radon gas is the #1 cause of lung cancer among non-smokers in the U.S.
• Nearly 50% of Fort Collins homes test above the EPA’s action level of 4 pCi/L.
• Homeowners can use DIY kits or hire certified professionals for testing.
• Mitigation systems can reduce radon levels by up to 99%, and assistance is available for qualifying households.​
• Experts recommend testing every 2–3 years, and always after renovations or before buying/selling a home.

What Is Radon, and Why Should You Care?

Radon forms naturally when uranium in the soil breaks down. It seeps upward through soil and rock and can enter your home through foundation cracks, gaps around pipes, and unfinished flooring.

Unlike carbon monoxide, radon doesn’t cause immediate symptoms—it works slowly, making long-term exposure especially dangerous.

According to the EPA and the Colorado Department of Public Health and Environment (CDPHE), radon exposure is linked to 21,000 lung cancer deaths annually in the U.S.

Why Fort Collins Homes Are at Higher Risk

• Colorado’s geology makes it one of the states with the highest radon levels nationwide. In Fort Collins specifically:
  
  
• About 1 in 2 homes test above the EPA’s recommended action level.
  
  
• Radon affects all types of homes—new builds, old homes, and even houses without basements.
  
  
• Local agencies such as the City of Fort Collins Air Quality Program and Larimer County Environmental Health provide discounted test kits and mitigation resources.
  ​
• Even brand-new homes are not immune—every home should be tested.

How to Test for Radon in Fort Collins

Professional Radon Testing

• Affordable and easy to find in stores or through local programs.
• Short-term kits (2–7 days) offer quick results.
• Long-term kits (90+ days) provide more accurate averages.
• A smart starting point if you’ve never tested before.

DIY Radon Test Kits

• Conducted by certified specialists in Fort Collins.
• More accurate, especially for real estate transactions.
• Includes detailed reports and recommendations for mitigation.

What If Your Radon Levels Are High?

If results are 4 pCi/L or higher, the EPA and CDPHE recommend taking action immediately.

Common mitigation strategies include:

• Sub-slab depressurization: A pipe-and-fan system that vents radon outdoors.
• Sealing foundation cracks: Reduces radon entry points.
• Improved ventilation: Helps dilute indoor concentrations.

📌 Cost: Most Fort Collins systems cost $800–$1,500

How Often Should You Test?

• Every 2–3 years if below the EPA’s action level.
• After renovations or HVAC changes.
• Whenever buying or selling a home.

​
Because radon levels fluctuate, long-term testing gives the most accurate results.

Final Thoughts

Radon may be invisible, but the risks it poses are undeniable. With Colorado’s geology and Fort Collins’ high radon levels, testing is not optional—it’s essential.
