From a hairline crack to a fully soaked crawl space, our De Graff crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Licensed & insured in OH · Written pricing
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
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.
Our De Graff crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for De Graff homeowners.
Odor is often the very first clue De Graff homeowners notice, well before any water is visible.
Small cracks in a De Graff foundation rarely stay small — seasonal ground movement tends to widen them over time.
Efflorescence is a reliable early sign that water is moving through your De Graff foundation wall right now.
A De Graff sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our De Graff schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two De Graff basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded De Graff basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
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 →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →A damp De Graff crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
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.
Request a Commercial Quote →Here's exactly what De Graff customers can expect from first call to final walkthrough.
A real technician asks the right questions to understand what's likely happening at your De Graff property before anyone drives out.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
Every De Graff quote is written before work starts, not estimated verbally and adjusted later.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every De Graff horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
We're not routing your call through a national center — the person who answers is close by.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
We'd rather earn a repeat De Graff customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked De Graff customers through this process many times.
Every De Graff job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every De Graff contract we sign.
