Halo Water Proofing is a WI-licensed Interior Drainage System company that treats every Green Bay job like it's the only one on the schedule.
We don't run a bidding war between crews. The Green Bay technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Green Bay homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Most Green Bay calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue Green Bay homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our Green Bay crews see.
Efflorescence is a reliable early sign that water is moving through your Green Bay foundation wall right now.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
This is one sign we tell Green Bay customers never to wait on — wall movement tends to progress, not resolve on its own.

No two Green Bay basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Green Bay basement doesn't wait for morning, and neither do we. Our crews get it out and start drying the space the same visit.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
