From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Ottawa before. We show up, we diagnose it straight, and we fix it right.

We're Halo Water Proofing — a OH-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Ottawa-area foundations, and exactly how to stop it.

Every technician on our Ottawa crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Most Ottawa customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Ottawa customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Ottawa-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Ottawa storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Ottawa call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Ottawa crews trace back to a drainage issue.
Every Ottawa property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Ottawa emergency crews extract standing water first, then diagnose the entry point so it doesn't happen again next storm.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Ottawa crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Most sump pump failures we see in Ottawa happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →Some Ottawa lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →Older Ottawa homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →Commercial properties in Ottawa carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.

You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Ottawa property.

No verbal estimates that change later. What's quoted for your Ottawa job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
There's no verbal quote that magically grows once the crew arrives at your Ottawa property — the written estimate is the final word.
Because we're actually based near Ottawa rather than routing calls through a national center, we can usually get someone out the same day you call.
Our repairs come with written, transferable warranties — a real asset if you sell the Ottawa property later.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.
We can supply the photo documentation and repair scope most Ottawa, OH carriers ask for before approving a claim.
Word of mouth is still how most Ottawa customers find us, which keeps our standards higher than a big out-of-town franchise.
"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
