Radon testing, mitigation and laboratory analysis are all certified activities in Pennsylvania, administered by the Department of Environmental Protection's Radon Division under the Commonwealth's Radon Certification Act. Certification covers both individuals and firms. If you are considering entering this trade in Pennsylvania, DEP's Radon Division is the authority on current requirements — start there rather than with a national training provider's summary.
Mitigation is practical construction work: coring slabs, running and sealing pipe, mounting fans, and carrying out the electrical work to supply them. The technical part is designing a pressure field that actually covers the whole slab, which is where experience shows and where under-designed systems fail.
This site is an information resource rather than a contracting firm, so we do not employ testers or mitigators. This page exists because people search for how to get into the trade in Pennsylvania and the answer is genuinely useful.
