From a hairline crack to a fully soaked crawl space, our Green Bay crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Licensed & insured in WI · Real warranties
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.
📞 +1-866-476-1348Most Green Bay calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
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.
This is one sign we tell Green Bay customers never to wait on — wall movement tends to progress, not resolve on its own.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
Whatever's going on with your Green Bay property, chances are we've already fixed something similar nearby this month.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
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 →Older Green Bay homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
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.
A real technician asks the right questions to understand what's likely happening at your Green Bay property before anyone drives out.
No jargon, no pressure — just a clear look at what's actually going on.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
You get documentation of the work plus a real warranty — not just a handshake.
Plenty of companies advertise Exterior Waterproofing in Green Bay — here's what actually separates the ones worth calling from the ones that aren't.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
Our crews stage locally near Green Bay, which is why most emergency calls get a technician on-site in under two hours.
Warranty terms are explained in plain language before you sign, with no fine-print surprises later.
We'd rather earn a repeat Green Bay customer with an honest fix than push a system you don't need.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every Green Bay job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Straightforward commercial quote, professional crew, no back and forth."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every Green Bay contract we sign.
