We diagnose the actual water source before we quote anything — no guessing, no upsell, just a plan sized to your basement.
Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.
We're bonded and insured for both residential and light commercial basement work across Greenville, NC.
Our Greenville, NC crews are staffed locally, so a wet basement call doesn't sit in a national queue for a week.
No hourly billing and no change orders once your basement floor is already open.
We use pin-type moisture meters and a flashlight-and-crowbar inspection to trace water back to its real entry point.
Every Greenville, NC Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
The core fix for most Greenville, NC basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.
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.
A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.
Poor window well drainage is one of the most overlooked Greenville, NC 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.
A technician walks the basement with a moisture meter, checking walls, floor, and cove joints to trace the water back to its actual source.
We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.
You'll get warranty paperwork and a walkthrough of how the system works so you know what to expect going forward.

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.
We keep the cut as narrow as possible and clean up debris before leaving the site.
Larger basements or those needing extensive crack repair can take a bit longer — we'll give you a realistic timeline in the written quote.
Not always — an isolated, non-leaking crack can sometimes be handled with injection alone.
We provide photos and moisture readings that many Greenville, NC homeowners have used to support a claim.
Warranty terms are often transferable if you sell the property later.
