Radon Mitigation in Spring Grove, PA

A Mill Town on Codorus Creek

Spring Grove is a borough west of York on PA Route 116, sitting along Codorus Creek with Jackson Township around it. For generations the town’s story has been tied to its paper mill, and the older streets near the center are part of the Spring Grove Borough Historic District. The homes there are older, many of them brick and frame with masonry basements. Farther out, Jackson Township adds postwar homes and newer subdivisions.

That mix gives Spring Grove a bit of everything. But one feature deserves its own section: the sump pit.

The Sump Pit Is Often the Biggest Leak

Plenty of basements in this part of York County have a sump pit and a pump. The pit is a hole in the floor that opens straight to the soil and the drain tile under the house. Left open, or covered with a loose lid, it’s often the single largest radon entry point in the basement.

It also matters for how a system works:

• Open pit, new system: the fan pulls basement air down through the pit instead of soil gas from under the slab. The system underperforms. We seal the pit with an airtight lid that still allows access.
• Drain tile around the footing: in some houses, suction through a sealed sump carries into the drain tile around the whole foundation, which can extend the system’s reach.
• Sump replacement later: a plumber swaps the pump, pulls the lid, and doesn’t reseal it. You may hear air hissing around the edge. The gauge on the radon pipe may change. This is one of the most common reasons an existing system stops working well.

Older Spring Grove Homes

The older houses near the center of town need the same care as any old York County basement: sealing along stone or masonry walls, attention to the joint where a later floor meets the original wall, and a pipe route planned through a basement that wasn’t designed for one. Old floor drains and abandoned pipe openings get checked too.

Postwar Homes in Jackson Township

The ranches and two-stories outside the borough usually have block or poured basements. Hollow block walls can carry soil gas upward inside the cores, so we look at the top of the block wall and any open block along with the slab. These tend to be good candidates for a single well-placed suction point, especially with a sealed sump helping.

Where to Start

If you haven’t tested, begin with radon testing. If your result is 4.0 pCi/L or higher, we’ll look at the sump, the drains, and every foundation area before quoting radon mitigation. And if you already have a system and something changed after sump or plumbing work, that’s a radon fan replacement and repair visit.
