Why Choose 48-Hour Radon Testing?

Radon is a radioactive gas and the second leading cause of lung cancer in the United States. Because it’s colorless, odorless, and invisible, the only way to know if your Denver-area home or business is safe is through a certified 48-hour radon test. Our NRPP-certified inspectors use continuous monitors that collect hourly readings, delivering fast, reliable, and accurate results — perfect for real estate transactions, new homeowners, or anyone concerned about indoor air quality.

Our 48-Hour Radon Testing Process

• Certified Continuous Radon Monitors: Advanced, EPA-approved devices for real estate testing.
• 48-Hour Data Collection: Measures radon levels hourly for at least 48 hours.
• Instant Digital Reporting: Results available immediately after the test concludes.
• Graphical Data: Includes hourly levels, averages, and EPA action level comparisons.
• Clear Mitigation Guidance: If radon levels exceed 4.0 pCi/L, we provide recommendations for next steps.

Our testing meets or exceeds EPA protocols for radon testing in homes, condos, townhomes, schools, and commercial properties.
