Radon testing when buying or selling a home

In many states, radon is a standard inspection item during a home sale. In Pennsylvania, the standard sale agreement includes a separate radon inspection option, sellers must disclose any known test results, and testing must be done by a DEP-certified tester.

How to do it

Buyers: schedule the radon test early in the inspection window. Results take a few days.
Use a certified tester. Their results carry more weight in negotiations.
If results are high, common options are a seller-installed system, a price credit, or an escrow for mitigation.
Sellers: if a system is installed, keep the post-mitigation test result to show future buyers.
