Interior drain tile, sump basins, and vapor barrier wall systems installed by technicians who've done this hundreds of times in Gaston, SC basements.
We've seen enough Gaston, SC basements to know that a wet spot in one corner rarely tells the whole story. Before we recommend drain tile or a sump upgrade, we trace the water back to where it's actually entering, not just where you noticed it.
We're bonded and insured for both residential and light commercial basement work across Gaston, SC.
Most inspection requests get a same-day or next-day appointment, not a two-week wait.
You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.
Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.
Every Gaston, SC Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.
Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.
Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.
We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.
Poor window well drainage is one of the most overlooked Gaston, SC basement leak sources, and it's often the cheapest fix on the list.
You describe what you're seeing — a wet spot, a musty smell, standing water — and we get a rough read on urgency before dispatching anyone.
We also check exterior grading and downspouts, since a lot of basement leaks start outside, not inside.
You'll see drain tile footage, sump specs, and labor broken out separately, not one vague lump-sum number.
You'll get warranty paperwork and a walkthrough of how the system works so you know what to expect going forward.

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