We built SGP Waterproofing around one idea: a South Carolina, SC property owner shouldn't have to wait three days for someone to look at a wet wall.
Every SGP Waterproofing technician working in South Carolina, SC carries the same licensing, the same insurance coverage, and the same set of tools whether the job is a single cracked footing or a full interior drainage system. We built the company on the idea that a homeowner shouldn't need three quotes and two weeks of waiting to get an honest answer.
Our dispatchers know the difference between a slow seep that can wait until morning and an active flood that can't, and they route calls accordingly. That triage system is the reason our average South Carolina, SC response time beats most of the national franchises operating in the same zip codes.
Older South Carolina, SC neighborhoods often have block foundations poured decades before modern drainage codes existed, while newer subdivisions tend to run poured concrete with a perimeter drain that was installed correctly but has since clogged with silt. Knowing which era of construction you're dealing with changes the repair plan before a single tool comes out of the truck.
We also see a lot of properties where a previous waterproofing attempt only addressed the symptom — a topical sealant painted over a cracked wall, for example — without solving the pressure or grading issue causing the crack in the first place. Part of every South Carolina, SC inspection is checking for that kind of prior patch job before we recommend anything new.
Water damage rarely announces itself with a flooded basement on day one. It usually shows up as one of these smaller signals first, and South Carolina, SC's seasonal moisture swings tend to speed the timeline up.
A persistent musty smell almost always means moisture is present somewhere in the wall assembly, even if you can't see a wet spot yet.
Those white, chalky mineral deposits on block or poured concrete walls are salt left behind after water has migrated through the concrete and evaporated.
Small stair-step cracks in block walls or vertical hairline cracks in poured walls tend to widen over a season or two as hydrostatic pressure keeps pushing.
Drywall that feels soft, bubbles, or shows a tide line near the floor is already absorbing groundwater — by the time you see it, the insulation behind it is usually soaked too.
A window well that fills with water during heavy rain is putting direct pressure on the glass and frame, and it's one of the most common entry points we find in older South Carolina, SC homes.
Puddling near the foundation that doesn't drain within a few hours usually means grading, gutters, or a failing perimeter drain — and it's the fastest path to a flooded basement.
Every job starts with the same on-site inspection, whether it's a single crack or a full interior drainage retrofit. Below are the services South Carolina, SC clients request most often.
Active flooding gets priority dispatch. We arrive with submersible pumps, air movers, and moisture-mapping tools to stop the water first and diagnose the long-term fix second.
Interior drain tile systems, sump pump installation, and vapor barrier wall systems make up the bulk of our residential basement work across South Carolina, SC neighborhoods.
Commercial jobs typically pair exterior membrane work with an interior collection system, since most existing commercial structures can't be fully excavated without major disruption.
Crack injection is often the most cost-effective South Carolina, SC repair when the crack is isolated and the wall itself hasn't bowed or shifted.
We install heavy-gauge vapor barriers, seal foundation vents, and add a dedicated sump basin so a damp South Carolina, SC crawl space stops feeding moisture into the floor joists above it.
Extending downspouts another six to ten feet away from the foundation solves more South Carolina, SC drainage problems than people expect, and we'll usually check that before recommending anything more invasive.
A dispatcher walks through symptoms with you on the phone so the crew that shows up already has a rough idea what they're dealing with.
A technician maps moisture readings, checks grading, and identifies whether the source is groundwater, surface water, or condensation.
We put the scope, materials, and price in writing so you can compare it against anyone else's estimate line for line.
Most residential jobs finish in one to three days, and we walk the property with you afterward to confirm every drain, pump, and seal is working.
You'll know the total cost before we start — no hourly billing, no surprise add-ons once the walls are already open.
Same-day availability isn't guaranteed on every job, but our South Carolina, SC dispatch is built to prioritize it whenever the situation calls for it.
We also carry Category 1, 2, and 3 water classification protocols for jobs where the source water isn't clean groundwater.
We stand behind the installation with a written warranty, and we'd rather send a crew back for a free fix than lose a customer over it.
Warranty terms vary by scope of work, and our technician will walk through exactly what's covered before you sign off on the quote — nothing vague, nothing left to interpretation.
Our South Carolina, SC coverage spans dozens of cities and the unincorporated areas between them. If you're unsure whether we reach your address, call and we'll tell you honestly.

"We had water coming in around the window well every time it rained hard. They regraded the area and sealed the well, and we haven't had a drop since."
— South Carolina, SC Homeowner
"The crack in our basement wall had been leaking for a year before we finally called. Injection took less than an afternoon and it's been dry since."
— South Carolina, SC Seller
"Our crawl space had standing water and a mold smell we couldn't get rid of. They pumped it out, encapsulated the whole thing, and added a dedicated sump discharge line."
— South Carolina, SC Homeowner
"Our old sump pump died during the biggest storm of the year and we got water in the finished basement. They replaced it with a battery backup system so we're covered even during a power outage."
— South Carolina, SC Customer
"Property management hired them to fix water coming through the garage ceiling. They scheduled the membrane work in phases so we never had to close the whole garage."
— South Carolina, SC Property Manager
"They found the actual source of the dampness instead of just recommending a dehumidifier and calling it done. Been dry for over a year now."
— South Carolina, SC Homeowner
Most South Carolina, SC emergency calls get a technician on-site within a few hours; non-urgent inspections are typically scheduled within one to two business days.
Pricing is disclosed in full before you sign anything, and we walk through each line item so nothing is a surprise later.
We handle active flooding, sump pump failures, and failed foundation walls with same-day dispatch, portable extraction pumps, and temporary water mitigation.
Cost depends on square footage, the type of system needed, and whether the fix is interior drainage, exterior membrane work, or both — we won't quote a number without an in-person inspection first.
No crack is too small to inspect; catching it early usually means a smaller repair bill down the road.
We install both — interior drain tile and sump systems for most residential jobs, and exterior membrane or French drain systems when the source is surface water or when excavation is practical.
Most residential interior drain tile or sump installations finish in one to three days; larger commercial membrane projects can take longer depending on square footage.
We're happy to provide the documentation adjusters typically request, though we recommend confirming your specific coverage details directly with your insurance provider.
A French drain without a sump pump just relocates water to one spot; the pump is what actually discharges it away from the home.
We back our work with a written, often transferable warranty — useful if you sell the property before the coverage period runs out.
Standing water doesn't stop us from starting; we extract it as the first step, then proceed with vapor barrier and drainage installation.
Commercial scheduling is handled separately from residential dispatch so larger projects get the coordinated planning they need.
One call gets you a licensed technician, a written quote, and a same-day time window.
