From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in De Pere before. We show up, we diagnose it straight, and we fix it right.
Halo Water Proofing is a licensed and insured Basement Waterproofing company built around one idea: show up when you say you will, explain the problem in plain language, and fix it so it stays fixed.
We don't send apprentices to figure it out on your dime. Every De Pere 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.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our De Pere technicians hear about most often before an inspection.
Odor is often the first sign De Pere customers notice, well before any visible water shows up.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
Efflorescence is a clear sign that water is actively passing through your De Pere foundation wall, even if you've never seen standing water.
A pump under constant strain tends to fail at the worst possible time — usually during the next big De Pere storm.
This is one sign we tell De Pere customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue De Pere homeowners notice, even though the moisture issue started in the basement months earlier.
Every De Pere property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your De Pere basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew fast, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our De Pere crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Most sump pump failures we see in De Pere happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →For De Pere properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our De Pere crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We can phase larger De Pere commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.

No verbal estimates that change later. What's quoted for your De Pere job is what's invoiced.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
Our trucks stage locally around De Pere, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
If your De Pere basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.

"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
