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.
