Licensed Waterproofing specialists serving Newfane, NY with written warranties on every job, residential and commercial alike.

SGP Waterproofing is a licensed and insured Waterproofing contractor serving homeowners, property managers, and commercial building owners across Newfane, NY. We didn't start as a marketing company that added waterproofing to a service list — our crews came up running sump pumps, pouring interior drain tile, and injecting epoxy into foundation cracks long before the trucks had our name on the door.
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 Newfane, NY response time beats most of the national franchises operating in the same zip codes.
Soil composition changes how much hydrostatic pressure builds against a foundation wall, and Newfane, NY's mix of clay-heavy and sandy soils behaves differently depending on the neighborhood, sometimes block to block. A crew that hasn't worked the area tends to size drainage systems using generic assumptions instead of what's actually under the yard.
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 Newfane, NY inspection is checking for that kind of prior patch job before we recommend anything new.

Most Newfane, NY water intrusion problems don't start as a flood — they start small, and they get worse on a schedule. Here's what our technicians look for on a first inspection.
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.
Bubbling paint or soft drywall near the baseboards is one of the last signs to show up, which means moisture has typically been present for weeks already.
If your window wells hold water for more than an hour after a storm, that water has nowhere to go but toward the seal around your basement window.
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 Newfane, NY clients request most often.
When a sump pump fails during a storm or a foundation wall gives way, we dispatch a crew with portable pumps and extraction equipment within hours, not days.
Most Newfane, NY basements need a combination of interior drainage and a properly sized sump pump — we size the system to your square footage and soil type, not a one-size-fits-all package.
Parking garages, below-grade retail space, and multi-family basements need waterproofing membranes and drainage systems rated for continuous traffic and higher hydrostatic load.
We classify every crack before injecting it — structural cracks get epoxy, active leaks get flexible polyurethane that expands to fill voids behind the wall.
Encapsulation starts with removing standing water and debris, then sealing the space with a 12-20 mil liner and a dehumidifier sized to the cubic footage.
We trace surface water back to its source, which is often a downspout discharging too close to the foundation or a grade that slopes the wrong direction entirely.
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.
We walk the interior and exterior with a moisture meter and flashlight, tracing water back to its actual entry point instead of guessing.
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.
Because our crews are based in and around Newfane, NY, we're not routing your call through a national scheduling system that books you two weeks out.
We also carry Category 1, 2, and 3 water classification protocols for jobs where the source water isn't clean groundwater.
If a sealed crack reopens or a sump system underperforms within the warranty window, we come back and make it right at no extra charge.

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 throughout Newfane and the surrounding Newfane, NY service area, including the zip codes listed below. If you're just outside the boundary, call anyway — we often still make the trip.

"Our basement flooded during a storm at 2am and someone actually picked up the phone. The crew had pumps running before sunrise and came back two days later to install the drain tile system."
— Newfane Homeowner
"We were selling the house and the inspector flagged a foundation crack. They came out within two days, injected epoxy, and gave us documentation for the buyer's lender."
— Newfane 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."
— Newfane Homeowner
"Sump pump failed overnight and flooded part of our storage room. New pump was installed with a backup battery the same afternoon we called."
— Newfane 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."
— Newfane Property Manager
"We'd been dealing with musty smell in the basement for years and finally found out it was efflorescence building up behind the paint. Interior drain tile solved it for good."
— Newfane Homeowner
For active flooding we prioritize same-day dispatch across our Newfane, NY coverage area; routine inspections usually book within 48 hours.
Yes — every job gets a flat-rate, written quote before work begins, and that number doesn't change once the crew is on-site.
Emergency crews are equipped to stabilize the situation immediately, then schedule the permanent fix once the immediate flooding risk is under control.
Pricing varies with scope, but every Newfane, NY customer gets an itemized written estimate before any work is authorized, so there's never a guessing game.
Hairline cracks are actually the ideal time to call, since injection repair is faster and cheaper before hydrostatic pressure has a chance to widen the gap.
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.
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.
In most cases yes — a French drain collects water, but it still needs a sump pump to actually move that water out and away from the foundation.
We back our work with a written, often transferable warranty — useful if you sell the property before the coverage period runs out.
Yes — we pump out existing standing water first, then move into encapsulation and sump installation once the space is dry enough to work in safely.
We work with property managers, HOAs, and commercial building owners across Newfane, NY in addition to single-family homes, including parking structures and multi-unit basements.
One call gets you a licensed technician, a written quote, and a same-day time window.
