York County, PA
Radon guidance for Dallastown, south of York on the Route 74 corridor.
Dallastown is a compact borough with a largely older housing stock, and like most of York County's boroughs it combines full basements with foundations built long before soil gas was a design consideration. That combination is the standard candidate for testing.
Something worth knowing if you are in a transaction here: radon is one of the most commonly negotiated items on a York County home sale, and mitigation is frequently handled as a seller concession. If you are selling, testing before you list puts you in a considerably better position than discovering an elevated result during the buyer's inspection with a settlement date approaching.
Independent guidance on radon testing, mitigation costs and DEP-certified contractors for homeowners in Dallastown and the surrounding parts of York County.
A seller who already knows the number controls the conversation. One who finds out during the buyer's inspection is negotiating under a deadline.
Where another party relies on the result, use a DEP-certified tester rather than a DIY kit.
Where mitigation is part of a transaction, the other side's agent will ask who did the work. A DEP-certified firm is the answer that does not create a problem at settlement.
In a sale, the post-mitigation test is not just quality control — it is the document that closes out the negotiation. Make sure you get a copy.
Ask about a test result, what a Dallastown mitigation quote should include, or how to check a contractor's DEP certification.
