Hanover and Penn Township form the second-largest market in York County, and the geology under them is a patchwork: the Hanover-area limestone belt runs through the borough and east toward Spring Grove, while diabase and Triassic sediments push in from the Adams County side around McSherrystown and Conewago Township. That patchwork is why Hanover radon readings are so inconsistent — we have tested new homes in the developments off Baltimore Street and Grandview Road at 3 pCi/L and older homes a mile away on Broadway at 25 pCi/L. There is no way to know without a test.
Hanover's housing stock ranges from dense 1890s–1930s brick rowhomes and doubles around the square and along Carlisle, Baltimore and Frederick Streets — stone foundations, low ceilings, sometimes shared basements — to sprawling 1990s–2010s subdivisions in Penn and West Manheim Townships with poured foundations and, in many cases, passive radon rough-ins that just need a fan. We install both, and we handle the Hanover-area farm properties toward Abbottstown and Spring Grove that combine a stone basement, a crawl space addition and a private well in one job. Systems in Hanover follow the same DEP standards and come with the same post-mitigation test and guarantee as everywhere else we work.

Radon Mitigation in Hanover — Local Notes
- •Downtown Hanover rowhomes with shared basements need suction on each side of the party wall.
- •Penn Township subdivisions built after 2005 frequently have passive rough-ins — check the basement for a capped 3-inch PVC pipe labeled 'radon' before assuming you need a full install.
