Licensed Waterproofing specialists serving Corunna, IN 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 Corunna, 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.
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 Corunna, IN response time beats most of the national franchises operating in the same zip codes.
Older Corunna, IN neighborhoods often have block foundations poured decades before modern drainage codes existed, while newer subdivisions tend to run poured concrete with a perimeter drain that was installed correctly but has since clogged with silt. Knowing which era of construction you're dealing with changes the repair plan before a single tool comes out of the truck.
Because we've worked enough Corunna, IN 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.
Water damage rarely announces itself with a flooded basement on day one. It usually shows up as one of these smaller signals first, and Corunna, IN's seasonal moisture swings 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.
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.
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.
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.
We scope every Corunna, IN 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 across Corunna, IN neighborhoods.
Commercial jobs typically pair exterior membrane work with an interior collection system, since most existing commercial structures can't be fully excavated without major disruption.
Crack injection is often the most cost-effective Corunna, IN 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 Corunna, IN crawl space stops feeding moisture into the floor joists above it.
Sometimes the fix isn't inside the wall at all — regrading the soil away from the foundation and adding a French drain can solve a moisture problem before water ever reaches the block.
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.
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.
You'll know the total cost before we start — no hourly billing, no surprise add-ons once the walls are already open.
Same-day availability isn't guaranteed on every job, but our Corunna, IN 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.
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 Corunna, IN comes with a written, transferable warranty — useful if you sell the property before the coverage period ends.
