What Is Radon and Why Is It Dangerous?

Radon is a naturally occurring radioactive gas that forms when uranium breaks down in soil, rock, and water. It enters homes through cracks in foundations, gaps around pipes, and other structural openings.


The problem?


Radon is completely odorless, colorless, and tasteless, which means the only way to detect it is through proper testing.


Health Risks of Radon Exposure


Long-term exposure to high radon levels is the second leading cause of lung cancer, according to the EPA. Even moderate levels over time can increase health risks significantly.


Why Radon Is Common in Colorado


Homes in Colorado, including Denver metro areas, often have higher radon levels due to local geology. That’s why radon testing is not just recommended, it’s essential.

When Should You Get a Radon Test?

You Should Schedule Radon Testing If:


  • You’re buying a home

  • You’ve completed renovations (especially basements)

Testing is quick, affordable, and can prevent serious long-term health consequences.

Understanding Your Radon Test Results

Radon levels are measured in picocuries per liter (pCi/L).


EPA Guidelines:


  • 0–2.0 pCi/L: Low risk (ideal range)
  • 2.0–4.0 pCi/L: Moderate risk (consider mitigation)
  • 4.0+ pCi/L: High risk (mitigation recommended)


If your home tests at or above 4.0 pCi/L, taking action to reduce radon levels is strongly advised.

What Happens If Radon Levels Are High?

If elevated radon levels are detected, don’t panic, radon issues are very common and fixable.


Common Radon Mitigation Solutions:


  • Sub-slab depressurization systems
  • Vent pipe systems with fans
  • Sealing foundation cracks and openings
  • Improving home ventilation


We provide clear recommendations and can guide you toward the next steps to reduce radon levels effectively.
