We built SGP Waterproofing around one idea: a property owner shouldn't have to wait three days for someone to look at a wet wall, no matter what state they're in.
We're a licensed, insured Waterproofing outfit built around local crews in every region we serve — different soil types, different freeze-thaw cycles, different generations of basement construction depending on where you are. Every technician on our crew has logged real hours crawling through wet crawl spaces, not just reading about them.
We keep crews staffed locally in each market rather than routing every call through one national center, which means the technician who answers your questions on the phone is often the same person standing in your basement a few hours later.
Freeze-thaw cycles, seasonal rainfall patterns, and water table depth all shift how urgently a given crack or seep needs attention depending on where the property sits. We track these regional patterns because they change how we prioritize scheduling during storm season versus a slow drip in the middle of a dry month.
Because our crews have worked enough basements in their region to recognize patterns, they can often tell within the first ten minutes of an inspection whether a problem is isolated or connected to a larger drainage issue affecting the whole block.
Water damage rarely announces itself with a flooded basement on day one. It usually shows up as one of these smaller signals first, and seasonal moisture swings in many regions 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.
A crack that's a sixteenth of an inch wide today can become a sixteenth of an inch wider by next spring if the pressure behind the wall isn't relieved.
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 homes nationwide.
Water that pools against your foundation after every rain is telling you the drainage system, whatever's left of it, has stopped doing its job.
We scope every job in person before quoting it, because two houses with the same symptom rarely need the same fix. These are the five services that make up most of our workload.
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 in the neighborhoods we serve.
We work with property managers on phased scheduling so a commercial waterproofing retrofit doesn't shut down an entire building at once.
If a wall is bowing rather than just cracked, we'll flag that during the inspection since injection alone won't address a structural deflection issue.
We install heavy-gauge vapor barriers, seal foundation vents, and add a dedicated sump basin so a damp crawl space stops feeding moisture into the floor joists above it.
Extending downspouts another six to ten feet away from the foundation solves more drainage problems than people expect, and we'll usually check that before recommending anything more invasive.
You describe what you're seeing and we ask a few questions to gauge urgency before anyone gets in a truck.
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.
Every quote breaks down materials and labor separately, so you can see exactly what you're paying for instead of one vague lump sum.
Local staffing means the technician answering your call today can usually be on-site the same day, not on a waitlist behind jobs from another region entirely.
Every technician trains on interior drain tile installation, sump system sizing, and crack classification before they lead a job on their own.
Warranty callbacks get the same dispatch priority as a new emergency, because a repeat leak is still an active problem for you.
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.
We dispatch crews to cities and towns across the states we operate in, with local technicians staged in each region to keep response times short no matter where you're located.
Visit any state or city page on this site for the specific coverage details in that area, or call +1-866-476-1348 and a dispatcher can confirm availability for your address directly.
"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."
— Verified 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."
— Verified Seller
"The crawl space under our addition never dried out properly. Full encapsulation with a dehumidifier fixed it in one visit."
— Verified 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."
— Verified 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."
— Verified 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."

Most 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.
Emergency crews are equipped to stabilize the situation immediately, then schedule the permanent fix once the immediate flooding risk is under control.
We avoid quoting ballpark numbers over the phone because two basements with the same symptom can need very different fixes.
No crack is too small to inspect; catching it early usually means a smaller repair bill down the road.
The right system depends on access, budget, and what's actually driving the water in — we'll explain the trade-offs before you decide.
We give you a realistic timeline in the written quote so you can plan around the crew being on-site.
We can document moisture readings, photos, and scope of damage to support an insurance claim, though coverage and claim approval are ultimately determined by your carrier.
A French drain without a sump pump just relocates water to one spot; the pump is what actually discharges it away from the home.
Warranty length and coverage vary by service type, and we'll spell out the specifics in writing before the job starts.
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.
