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

Halo Water Proofing is a licensed and insured Exterior Waterproofing company built around one idea: show up when you say you will, explain the problem in plain language, and fix it so it stays fixed.

We don't send apprentices to figure it out on your dime. Every Waterloo 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.
📞 +1-866-476-1348Most Waterloo customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Stair-step cracks in block foundations are a common early warning sign we see across Waterloo-area homes.
Efflorescence is a clear sign that water is actively passing through your Waterloo foundation wall, even if you've never seen standing water.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Waterloo storm.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Waterloo 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 Waterloo emergency crews extract standing water first, then diagnose where it's getting in 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 Waterloo 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 Waterloo 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 →An interior drain tile system channels water to a sump pump before it ever reaches your Waterloo basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →A damp, uninsulated crawl space under a Waterloo 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 →We work directly with Waterloo property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.

"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."
