Homeowner radon guide
Should I test my home for radon?
Radon cannot be reliably predicted for one home from a map, neighboring result, age, or foundation type.
Every home is different
Construction details, soil conditions, pressure, and weather can produce different results in nearby homes.
Choose the right test
Follow the device instructions and applicable testing protocol, especially during real-estate transactions.
What to do next
Use the cost estimator for planning or search for professionals whose recorded service area matches your ZIP code.
