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

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

Every technician on our Mayville 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.
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 Mayville customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
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 Mayville-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 Mayville storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Mayville call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Mayville 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 Mayville emergency crews pump out the basement first, then diagnose the entry point so it doesn't happen again next storm.
