Wet basement? Cracked foundation? A Halo Water Proofing crew can be at your Dunlap property within hours — upfront pricing, no guesswork, no pressure.

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

Every technician on our Dunlap 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 Dunlap 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 Dunlap customers notice, well before any visible water shows up.
Hairline cracks can widen over a Dunlap winter's freeze-thaw cycle and become active leak points by spring.
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.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Dunlap call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Dunlap crews trace back to a drainage issue.
Every Dunlap 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 Dunlap emergency crews pump out the basement first, then diagnose the entry point so it doesn't happen again next storm.
Call for Emergency Service →Freeze-thaw cycles in Dunlap, IL push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
