Who’s behind this
York PA Radon Pros is run by Tom Bartokowski, a York builder who vets radon mitigation companies rather than doing the work himself. Nobody pays to be on the list. Read more on the About page or meet Tom. Run a company that should be listed? Get listed. Everything else is in the Resources index and the FAQs.
Official state and federal radon contacts, including the DEP directory and free test kits, are on our Radon Resources page.
