Radon Mitigation in New Freedom, PA 17349

New Freedom is the southernmost borough in York County, just above the Mason-Dixon line on the Heritage Rail Trail, and it sits on the same fractured schist and gneiss that gives Shrewsbury and Glen Rock their high radon numbers. DEP data for the 17349 ZIP code consistently shows a majority of tested basements above the 4.0 pCi/L action level, and readings above 20 pCi/L are not unusual on the ridges east of the borough toward Stewartstown. Many New Freedom residents commute to Baltimore, and Maryland buyers moving north are often surprised by how routine radon mitigation is here.

The borough core is railroad-era homes from the late 1800s on stone and brick foundations with shallow basements; the surrounding Shrewsbury Township developments off Route 851, Franklin Church Road and Main Street are mostly 1990s–2010s colonials with poured basements and often a passive stub pipe. Stone foundations get extra floor-wall sealing and sometimes a sub-membrane crawl space system; newer homes typically need a high-static fan on the existing rough-in plus a post-mitigation test. Homes on wells in the township should add a water radon test.
