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

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

Every technician on our Greendale 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 Greendale 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 Greendale-area homes.
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 Greendale call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Greendale 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 Greendale every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Greendale 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 Greendale, WI 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 Greendale after heavy rain. We install battery backup units 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 Greendale basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Greendale crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We work directly with Greendale property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
