Halo Water Proofing is a OH-licensed Foundation Crack Repair company that treats every De Graff job like it's the only one on the schedule.
Every De Graff technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old De Graff homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our De Graff crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your De Graff foundation wall right now.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our De Graff crews handle most.
A flooded De Graff basement doesn't wait for morning, and neither do we. Our crews get it out and start drying the space the same visit.
Get Emergency Help →Seasonal ground movement in De Graff tends to widen existing cracks over time, so sealing early usually costs less than waiting.

Book a Pump Check →Some De Graff properties need both systems working together — we'll say so honestly instead of selling just one.
