Radon Mitigation in West York, PA 17404

West York borough and the surrounding West Manchester and Manchester Township neighborhoods — Shiloh, Weigelstown's southern edge, the streets off Carlisle Road and West Market Street — mix tight early-1900s rowhomes on stone and brick foundations with post-war ranches and 1990s subdivisions. Radon readings vary block by block here because the limestone under West York gives way to shale and sandstone as you move north and west toward Dover, and we have measured 3 pCi/L and 30 pCi/L in houses a few hundred yards apart.

The older borough homes are the interesting installs. A stone foundation with a partial dirt floor or a slab poured decades after the house was built has more entry points than a modern basement, and getting suction to spread under a thin, cracked slab takes a diagnostic test hole or two before we choose a suction location. We have done dozens of these narrow rowhome installs in West York and York City, routing pipe up an interior chase or through the rear wall to keep the front facade clean. For the townships, standard exterior sub-slab systems on poured or block foundations are the norm, and homes with a sump pit get a sealed-lid system that doubles as moisture control.
