Licensed & insured in WI · Written pricing
We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Every Green Bay technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
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.
Talk to a real Green Bay technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Green Bay homeowners.
A musty smell usually means moisture is already moving through your Green Bay basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Green Bay schedule.
Peeling paint near the floor upstairs is one of the last signs Green Bay homeowners connect to a basement problem.
Whatever's going on with your Green Bay property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Green Bay emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Seasonal ground movement in Green Bay tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →Most Green Bay pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →Some Green Bay properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →A damp Green Bay crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →We handle below-grade waterproofing for Green Bay property managers and business owners, scheduled around your operating hours to limit disruption.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Green Bay horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
We're not routing your call through a national center — the person who answers is close by.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
If your Green Bay basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Word of mouth is still how most Green Bay customers find us, which keeps our standards high.
