Basements flood, crawl spaces flood, and parking garages flood — usually at the worst possible hour. Our New Lisbon, IN technicians are staged and ready to respond the moment you call.

SGP Waterproofing is a licensed and insured Waterproofing contractor serving homeowners, property managers, and commercial building owners across New Lisbon, IN. 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.
We keep our crews local rather than routing calls through a national call center, which means the technician who answers your questions on the phone is often the same person standing in your basement two hours later. That continuity cuts down on the miscommunication that drags out so many waterproofing jobs.
Freeze-thaw cycles, seasonal rainfall patterns, and water table depth all shift how urgently a given crack or seep needs attention in New Lisbon, IN 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.
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 New Lisbon, IN inspection is checking for that kind of prior patch job before we recommend anything new.

Most New Lisbon, IN 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.
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.
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.
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 New Lisbon, IN clients request most often.
Once the water is out, we run air movers and dehumidifiers to bring humidity down before mold has a chance to establish itself in drywall or subfloor.
Most New Lisbon, IN 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.
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 New Lisbon, IN 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.
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.
You get a flat-rate, itemized quote before any work starts — no verbal estimate that changes once the crew shows up.
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.
Because our crews are based in and around New Lisbon, IN, we're not routing your call through a national scheduling system that books you two weeks out.
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.

Every interior drainage system, sump installation, and crack repair we complete in New Lisbon, IN comes with a written, transferable warranty — useful if you sell the property before the coverage period ends.

"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."
— New Lisbon 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."
— New Lisbon 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."
— New Lisbon 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."
— New Lisbon Customer
"Our parking garage had a persistent leak coming through the deck above the lower level. They installed a membrane system and coordinated the work around tenant parking so nobody was displaced."
— New Lisbon Property Manager

— New Lisbon Homeowner
For active flooding we prioritize same-day dispatch across our New Lisbon, IN coverage area; routine inspections usually book within 48 hours.
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.
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.
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 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.
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.
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.
