Why Radon Testing Matters
Invisible & Odorless
Radon gas has no color, odor, or taste — the only way to know your home’s level is to test it.
#2 Cause of Lung Cancer
Radon causes approximately 21,000 lung cancer deaths per year in the US, second only to smoking.
Mitigation Works
EPA-certified mitigation systems can reduce indoor radon levels by up to 99% in most homes.
Test Your Home First
EPA recommends testing before calling a mitigation contractor. Short-term test kits are inexpensive and give you the data you need.
Short-Term Test Kit
2–7 day test. Mail-in lab analysis included. Fastest way to get a result.
Long-Term Test Kit
90+ day test. More accurate average reading for your home year-round.
Continuous Monitor
Real-time digital display. Track radon levels 24/7 after mitigation.
Test first. If results exceed 4 pCi/L, use the directory above to find a certified mitigation contractor in your area.
Don’t Wait — Test Your Home for Radon
Radon is responsible for more deaths than drunk driving every year. Find a certified specialist in your state and get tested — it’s quick, affordable, and could save your life.
