What to do next
Test your home
Radon levels vary between neighboring houses, so area data can't tell you your own home's level. A short-term test takes 2 to 7 days in the lowest lived-in floor. A long-term test (90 days or more) gives a more reliable average.
If your result is 4 pCi/L or more, fix it
A certified professional installs a sub-slab system: a pipe and a quiet fan that pull radon from under the foundation and vent it above the roof. It usually takes a day; the costs are above.
It works: across Pennsylvania, the typical level dropped from 7.7 to 1.0 pCi/L after mitigation, and 95% of homes ended up below the action level.
Use a certified professional
Pennsylvania requires radon testers and mitigators to be certified. The state publishes the list of certified mitigation firms by county.
