Wet basement? Cracked foundation? A Halo Water Proofing crew can be at your Green Bay property fast — upfront pricing, no guesswork, no pressure.

We're Halo Water Proofing — a WI-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Green Bay-area foundations, and exactly how to stop it.

Every technician on our Green Bay crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Green Bay technicians hear about most often before an inspection.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Stair-step cracks in block foundations are a common early warning sign we see across Green Bay-area homes.
Efflorescence is a clear sign that water is actively passing through your Green Bay foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Green Bay lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Green Bay call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Green Bay every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Green Bay emergency crews pump out the basement first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service →Freeze-thaw cycles in Green Bay, WI push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Green Bay lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →Some Green Bay lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Green Bay crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →Commercial properties in Green Bay carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Green Bay crews follow on every job.
You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Green Bay property.
A technician inspects the Green Bay property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
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 Green Bay, 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.

We can supply the photo documentation and repair scope most Green Bay, WI carriers ask for before approving a claim.
Word of mouth is still how most Green Bay customers find us, which keeps our standards higher than a big out-of-town franchise.
"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."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
Whether you're in the older, established parts of Green Bay or a newer subdivision still settling, our crews have likely already worked on a foundation like yours nearby.
