Radon Inspections

Protect Your Family with Certified Radon Testing

Radon is a silent, invisible, radioactive gas that can seep into homes through the ground. It's the second leading cause of lung cancer in the U.S.-yet it often goes undetected without proper testing. At Sam's Home and Commercial Inspectors, we specialize in professional Radon Inspections across Missouri, providing peace of mind whether you're buying, selling, or staying in your current home.

Why Radon Testing Is Crucial

Radon is odorless, tasteless, and colorless
1 in 15 U.S. homes has elevated radon levels
Only certified testing can accurately measure indoor radon
High levels can be mitigated-but only if detected
Real estate transactions increasingly require radon testing

What Our Radon Inspection Includes

Our inspections are conducted using EPA-approved, calibrated radon monitors for maximum accuracy. Each test includes:

Strategic placement of radon detection device(s)
48-hour continuous radon monitoring
Hourly readouts to detect fluctuations
Detailed reporting with EPA comparison guidelines
Certified recommendations if levels exceed 4.0 pCi/L

We use digital radon monitors-not charcoal kits-for more accurate and timely results.

Radon Testing Procedure & Prep Guide

To ensure reliable results, certain pre-test conditions and site protocols must be followed. Here's what to know:

Before Testing:

Keep windows and exterior doors closed 12 hours before test begins
Avoid using fans or ventilation systems that bring in outside air
Do not conduct major home renovations right before the test
Set HVAC to a normal, consistent setting

During the 48-Hour Test:

No opening of windows or exterior doors except for brief entry/exit
Avoid tampering with or relocating the monitor
Testing is typically conducted on the lowest livable level of the home
Devices are placed at least 20 inches above the floor, away from drafts or electronics

Failure to maintain test conditions may invalidate the results.

Understanding Your Results

Below 2.0 pCi/L: Excellent
2.0 - 3.9 pCi/L: Monitor; consider re-testing
4.0 pCi/L or higher: EPA recommends mitigation

We provide clear, same-day digital reports with actionable next steps and referrals to licensed mitigation experts if needed.

When Should You Get a Radon Inspection?

During real estate transactions (buyer or seller)
After home renovations, especially basement work
Every 2-5 years, even in previously low-radon homes
