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

Halo Water Proofing started as a small NY crew and grew because Ontario customers kept referring us to neighbors — that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Ontario job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Ontario technicians hear about most often before an inspection.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Stair-step cracks in block foundations are a common early warning sign we see across Ontario-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 Ontario storm.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Flooring that's cupping or warping near an exterior wall is a common clue our Ontario crews trace back to a drainage issue.
Every Ontario 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 Ontario emergency crews extract standing water first, then diagnose the entry point so it doesn't happen again next storm.
Call for Emergency Service →Freeze-thaw cycles in Ontario, NY push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Ontario after heavy rain. We install battery backup units so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Ontario basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →A damp, uninsulated crawl space under a Ontario home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →Commercial properties in Ontario 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.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Ontario crews follow on every job.
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 Ontario property.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
Because we're actually based near Ontario 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 Ontario property later.
If your Ontario basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We can supply the photo documentation and repair scope most Ontario, NY carriers ask for before approving a claim.
Our name is on trucks driving around Ontario every day — we don't cut corners on a job our neighbors will see.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"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."
