We built SGP Waterproofing around one idea: a Hollansburg, OH property owner shouldn't have to wait three days for someone to look at a wet wall.

We're a licensed, insured Waterproofing outfit built around Hollansburg, OH properties specifically — the clay-heavy soil, the seasonal freeze-thaw cycles, the older basements with parged walls that were never meant to hold back a modern water table. Every technician on our crew has logged real hours crawling through wet crawl spaces, not just reading about them.
Because we staff locally instead of subcontracting out to whoever's available, the estimate you get over the phone tends to match the invoice you get at the end of the job — no surprise line items, no upsell script.
Older Hollansburg, OH 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 Hollansburg, OH 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 Hollansburg, OH'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.
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.
We scope every Hollansburg, 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.
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.
We install interior perimeter drain systems tied into a sump basin, then finish the walls with a dimpled vapor barrier so any residual moisture is directed down, not trapped behind drywall.
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 Hollansburg, OH 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.
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.
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.
Every technician trains on interior drain tile installation, sump system sizing, and crack classification before they lead a job on their own.
Warranty callbacks get the same dispatch priority as a new emergency, because a repeat leak is still an active problem for you.

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


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