Interior drain tile, sump basins, and vapor barrier wall systems installed by technicians who've done this hundreds of times in Lexington, SC basements.
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 Lexington, SC.
Our Lexington, SC 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.
We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
The core fix for most Lexington, SC basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.
Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.
The cove joint where the floor meets the foundation wall is one of the most common Lexington, SC leak points, and we seal it as part of every interior system.
We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.
Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.
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.
We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.
Most residential basement jobs finish in one to three days, and we test the sump pump under load before we leave.

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 Lexington, SC homeowners have used to support a claim.
