Radon Mitigation in Hanover, PA

A Town Built in Layers

Hanover sits in the southwest corner of York County, close to the Adams County line and not far from Maryland. The borough dates back to the 1760s, and the Hanover Historic District around the center of town holds brick and frame houses, many with Pennsylvania German roots.

What makes Hanover interesting for radon is that it kept building through every era. Walk outward from the square and you’ll pass Victorian homes, then bungalows and Cape Cods, then the ranches and split-levels that went up from the 1950s on. Penn Township and West Manheim Township added newer subdivisions around all of it. Different decades, different foundations, and different ways for soil gas to get in.

Victorian and Early Brick Homes

The oldest houses near the center of town usually have masonry foundations, often stone, under brick walls. Basements tend to be low, crowded with mechanicals, and sometimes finished with a floor that was poured long after the house went up. Radon moves through the gaps in old stone and along the edge of that later floor. On these homes we spend extra time sealing and extra thought on where the pipe can go without chopping up a tight basement.

Bungalows and Cape Cods

The early 20th century and postwar houses are smaller, with full basements and usually block or poured walls. They’re often the most straightforward radon mitigation jobs in town. The thing to watch is hollow concrete block. Soil gas can travel up inside the block cores, so the top of the wall and any open block need attention along with the slab.

Ranches and Split-Levels

Split-levels are where a one-size system fails. A typical split has a basement under one section, a slab under another, and a garage slab on the end. A suction point in the basement may pull that slab down nicely and barely touch the family room. We check how far suction reaches before we promise a result, and add a second point where the house needs it.

Additions Built Decades Later

A lot of Hanover houses have a kitchen or family room addition on the back, built on a slab or over a crawlspace. That addition is its own foundation area. It’s one of the most common reasons a radon system brings the basement down but the house as a whole still tests high.

What We Look at in a Hanover Home

• Every foundation area, including additions and any enclosed porch
• The condition of stone or block walls, and any dirt floor sections
• The sump pit and floor drains
• Where a fan can mount outside the living space and where the pipe can run
• Whether the basement is finished, and how the family uses it

Test First if You Haven’t

If you don’t have a number yet, begin with radon testing. If you have a system and the gauge on the pipe reads level on both sides, the fan has likely quit, and a radon fan replacement is the fix. We handle both for Hanover homeowners as part of our York County radon mitigation work, with free same-day estimates.
