Licensed & insured in OH · 24/7 dispatch
Halo Water Proofing is a OH-licensed Basement Waterproofing company that treats every De Graff job like it's the only one on the schedule.
Our De Graff crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
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.
A musty smell usually means moisture is already moving through your De Graff basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
This is one sign we tell De Graff customers never to wait on — wall movement tends to progress, not resolve on its own.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two De Graff basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our De Graff emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →We seal active De Graff foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across De Graff after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your De Graff basement floor at all.
Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial De Graff jobs with written specs and a real timeline.
