From a hairline crack to a fully soaked crawl space, our Fostoria crew has seen it and fixed it. No guesswork, no scare tactics β just a clear plan and a fair price.
Licensed & insured in OH Β· Real warranties

Halo Water Proofing is a OH-licensed Foundation Crack Repair company that treats every Fostoria job like it's the only one on the schedule.
We don't run a bidding war between crews. The Fostoria technician who inspects your property is the same one who does the repair, start to finish.
Our Fostoria crew leads carry years of hands-on repair experience, not just sales training β 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 β not a vague callback promise.
π +1-866-476-1348Most Fostoria calls didn't start with a flood β they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Fostoria basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our Fostoria crews see.
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.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
Whatever's going on with your Fostoria property, chances are we've already fixed something similar nearby this month.
A flooded Fostoria 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 βNot 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 βAlready have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check βFor yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options βOlder Fostoria homes with vented crawl spaces see the biggest swings in seasonal humidity β encapsulation closes that off for good.
Get a Crawl Space Quote βWe can phase larger Fostoria commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote βNo pressure, no scripts β just what actually happens once you call +1-866-476-1348.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
No jargon, no pressure β just a clear look at what's actually going on.
No verbal number that quietly grows once the truck pulls up β the written quote is the final word.
You get documentation of the work plus a real warranty β not just a handshake.
We've heard every Fostoria horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Our major repairs come with written, transferable warranties β useful if you sell the Fostoria property later.
We'd rather earn a repeat Fostoria customer with an honest fix than push a system you don't need.
Filing a claim can be confusing β we've walked Fostoria customers through this process many times.
Every Fostoria job reflects on the next referral, so we treat each one like it matters.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything β basement's been dry since."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Straightforward commercial quote, professional crew, no back and forth."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
We back our Fostoria work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
