From a hairline crack in the block wall to three inches of standing water in the crawl space, our Broadway, OH crews handle it with the same flat-rate pricing and same-day dispatch every time.

SGP Waterproofing is a licensed and insured Waterproofing contractor serving homeowners, property managers, and commercial building owners across Broadway, OH. 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 Broadway, OH 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 Broadway, OH 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 Broadway, OH 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 Broadway, OH's seasonal moisture swings tend to speed the timeline up.
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.
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 Broadway, OH homes.
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 Broadway, OH 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.
A burst window well seal or a failed check valve can put inches of water in a basement in under an hour — our emergency crews carry truck-mounted extraction pumps and moisture meters to start mitigation the same day you call.
Most Broadway, OH 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.
Low-pressure epoxy injection bonds structural cracks back together, while polyurethane injection is better suited for cracks that are still actively leaking.
We install heavy-gauge vapor barriers, seal foundation vents, and add a dedicated sump basin so a damp Broadway, OH crawl space stops feeding moisture into the floor joists above it.
Exterior French drains paired with corrected grading are usually the first thing we recommend for a property that's flooding from the outside in, not the inside out.
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.
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.
We quote the whole job as one flat number, so the price on the invoice matches the price we quoted on day one.
Same-day availability isn't guaranteed on every job, but our Broadway, OH dispatch is built to prioritize it whenever the situation calls for it.
Every technician trains on interior drain tile installation, sump system sizing, and crack classification before they lead a job on their own.
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.

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


Our Broadway coverage area extends through most of the surrounding Broadway, OH 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.

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.
We handle active flooding, sump pump failures, and failed foundation walls with same-day dispatch, portable extraction pumps, and temporary water mitigation.
We avoid quoting ballpark numbers over the phone because two basements with the same symptom can need very different fixes.
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.
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 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.
We can walk your specific setup during an inspection and tell you honestly whether your existing drain needs a pump added.
Warranty length and coverage vary by service type, and we'll spell out the specifics in writing before the job starts.
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.
