Glendale may be small in size, but its homes and buildings are not immune to Colorado’s widespread radon concerns. With Colorado ranked among the highest-risk radon states in the country, testing is not just recommended—it’s essential.



Whether you’re living in a high-rise condo off Cherry Creek Drive South, managing a multi-unit complex near Leetsdale Drive, or selling a home near Infinity Park, A-1 Radon Testing Company is your trusted partner for local, expert radon testing.

Radon is a radioactive, odorless gas produced by the natural decay of uranium in soil and rock. It seeps into buildings through cracks in foundations, plumbing gaps, and even through well water—and it can accumulate to dangerous levels if left unchecked.

Here’s why radon testing is especially critical in Glendale and surrounding areas:

• Colorado is a Zone 1 EPA-designated state, meaning it’s at the highest risk for radon exposure.
  
• Over 50% of tested homes in the Denver area exceed the EPA’s action level of 4.0 pCi/L.
  
• Radon is the #1 cause of lung cancer among non-smokers.
  
• Even modern, well-sealed homes and condos in Glendale are vulnerable.
  
  

Our certified radon testing provides accurate, EPA-compliant measurements to keep your indoor air safe and protect the health of your family, tenants, or staff.
