Halo Water Proofing has been the Ottawa area's go-to call for Exterior Waterproofing because we answer the phone, show up on time, and stand behind the work.

We're Halo Water Proofing — a IL-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.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +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.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
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.
This is one sign we tell Ottawa customers not to wait on — wall movement tends to progress rather than resolve on its own.
Flooring that's cupping or warping near an exterior wall is a common clue our Ottawa crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Ottawa every day.
Storm season in Ottawa, IL means our emergency line gets busy fast — we triage calls by severity so active flooding at your Ottawa address jumps the queue ahead of routine inspections.
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 →Already have a sump pump that's failing or too small for your Ottawa lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →For Ottawa properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
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 →We can phase larger Ottawa commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

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.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
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.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
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.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
