The ground under Columbia

Susquehanna river terraces

Sand and gravel terraces stepping down to the Susquehanna, with older stone and rubble foundations.

The water table here rises and falls with the river. In a wet spring it can sit above your basement floor, which pushes water up through the slab and through the joints of a stone foundation rather than in through a crack. River-town housing stock is also the oldest in the county, so the foundation itself is usually mortar and field stone with a century of erosion behind it.

What we install in Columbia

Sub-slab drainage with a high-capacity sealed sump and battery backup, mortar repointing on stone walls, and encapsulation where the space is unfinished.

Most common call here

  • Damp slab in the middle of the floor, not just at the walls
  • Water rising through the floor rather than running down a wall
  • Crumbling mortar or loose stone in the foundation wall
  • Standing water that stays for weeks in spring

Questions from around Columbia

Straight answers

Do you actually work in Columbia?

Yes — regularly. Our office is at 2348 Harrisburg Pike in Lancaster, and Columbia (Columbia Borough) is a routine stop for our crews. Ask for the Columbia photos when the estimator comes out.

What does a job in Columbia usually cost?

It depends on how much wall needs draining and what the ground is doing. The estimate is free and in writing before anything starts, there is no money down, and financing is available.

Why does my neighbor need a different system?

The water table here rises and falls with the river. Two houses on the same street can sit on different grades and take water differently, which is why we read the water path before quoting.

How fast can you get here?

Free estimates in Columbia are usually within a few days, and we run 24/7 emergency service when there is active water in the house.

Is the warranty transferable if I sell?

Yes. The waterproofing warranty is for the life of the home and transfers to the next owner, which is worth having in hand at closing.
