We built SGP Waterproofing around one idea: a homeowner or property manager in Glenolden, PA shouldn't have to wait three days for someone to look at a wet wall.

SGP Waterproofing is a licensed and insured Waterproofing contractor serving homeowners, property managers, and commercial building owners across Glenolden, PA. 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 Glenolden, PA response time beats most of the national franchises operating in the same zip codes.
Freeze-thaw cycles, seasonal rainfall patterns, and water table depth all shift how urgently a given crack or seep needs attention in Glenolden, PA specifically. We track these patterns because they change how we prioritize scheduling during storm season versus a slow drip in the middle of a dry month.
Because we've worked enough Glenolden, PA basements to recognize patterns, we 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. That context shapes whether we recommend a small crack repair or a full interior system.

Most Glenolden, PA 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.
That damp, earthy smell in a finished or unfinished basement is usually mold or mildew feeding on moisture that's already gotten past your walls.
Efflorescence forms when water carries dissolved minerals through porous concrete and leaves them on the surface as it dries — a clear sign moisture is actively passing through.
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.
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.
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.
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 Glenolden, PA 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.
Interior drain tile systems, sump pump installation, and vapor barrier wall systems make up the bulk of our residential basement work across Glenolden, PA neighborhoods.
Parking garages, below-grade retail space, and multi-family basements need waterproofing membranes and drainage systems rated for continuous traffic and higher hydrostatic load.
Crack injection is often the most cost-effective Glenolden, PA 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 Glenolden, PA crawl space stops feeding moisture into the floor joists above it.
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.
Once installation wraps, we test the sump pump under load and walk you through the warranty paperwork before we leave the site.
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 out-of-town jobs.
Our crews run truck-mounted extraction units, moisture meters, and thermal imaging cameras — not a shop-vac and a guess.
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.

We document every job with photos, moisture readings, and a copy of the warranty terms, so there's a paper trail if you ever need to reference the work again.


Our Glenolden coverage area extends through most of the surrounding Glenolden, PA communities. Give us a call even if your address falls just outside the zone below; we'll let you know honestly if we can reach you same-day.

"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."
— Glenolden 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."
— Glenolden Seller
"The crawl space under our addition never dried out properly. Full encapsulation with a dehumidifier fixed it in one visit."
— Glenolden 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."
— Glenolden 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."
— Glenolden 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."
— Glenolden Homeowner
Response time depends on call volume and severity, but emergency water intrusion always jumps the queue ahead of routine estimates.
We quote the full scope in writing after the inspection, so there's no hourly billing or surprise change orders once installation starts.
Our emergency response covers water extraction, temporary pump-outs, and emergency crack sealing to stop active intrusion until permanent repairs are scheduled.
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.
We repair cracks of nearly any size — hairline cracks are often the easiest and least expensive to seal with polyurethane or epoxy injection before they widen.
The right system depends on access, budget, and what's actually driving the water in — we'll explain the trade-offs before you decide.
A single crack injection can be done in an afternoon, while a full interior drainage system typically runs two to three days start to finish.
We're happy to provide the documentation adjusters typically request, though we recommend confirming your specific coverage details directly with your insurance provider.
We can walk your specific setup during an inspection and tell you honestly whether your existing drain needs a pump added.
Yes, every interior drainage, sump, and crack repair job comes with a written warranty, and terms are explained in full before you approve the quote.
We assess the water depth and source first, since active groundwater intrusion changes how we sequence the encapsulation work.
Commercial scheduling is handled separately from residential dispatch so larger projects get the coordinated planning they need.
