Halo Water Proofing has been the Windsor area's go-to call for Interior Drainage System 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 Windsor 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 Windsor 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 Windsor 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.
Hairline cracks can widen over a Windsor 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.
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 Windsor 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 Windsor every day.
When your Windsor basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Freeze-thaw cycles in Windsor, WI push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
