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

Halo Water Proofing started as a small IL crew and grew because Algonquin 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 Algonquin 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.
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 Algonquin 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 Algonquin 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.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
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 Algonquin crews trace back to a drainage issue.
Every Algonquin 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 Algonquin emergency crews remove the water first, then diagnose the entry point so it doesn't happen again next storm.
Call for Emergency Service →Freeze-thaw cycles in Algonquin, IL 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 Algonquin after heavy rain. We install right-sized primary pumps 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 Algonquin basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Older Algonquin homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
