FAQ

What Lancaster, PA Customers Ask Us Most About Basement Waterproofing

How much does interior drain tile installation cost?

Cost depends on linear footage, sump basin size, and whether cove joint sealing is included — we won't give a number without an in-person inspection.

Will you cut into my basement floor?

Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

How long does basement waterproofing take?

Most residential interior drain tile and sump installations finish in one to three days depending on basement size.

Do I need a sump pump if I'm just sealing a crack?

If the crack is actively weeping or part of a larger drainage issue, we'll recommend a full system instead of a spot fix.

Is basement waterproofing covered by insurance?

We provide photos and moisture readings that many Lancaster, PA homeowners have used to support a claim.

Do you offer a warranty on basement waterproofing work?

Yes, every interior drain tile and sump installation comes with a written warranty, explained in full before you approve the quote.
