Halo Water Proofing has been the Greenville area's go-to call for Exterior Waterproofing because we answer the phone, show up on time, and stand behind the work.

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

Every technician on our Greenville 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.
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 Greenville 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.
Hairline cracks can widen over a Greenville winter's freeze-thaw cycle and become active leak points by spring.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Greenville lot's water table.
This is one sign we tell Greenville customers not to wait on — wall movement tends to progress rather than resolve on its own.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Greenville property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Greenville emergency crews pump out the basement first, then diagnose where it's getting in so it doesn't happen again next storm.
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 Greenville 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 Greenville happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Greenville basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →A damp, uninsulated crawl space under a Greenville home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →We work directly with Greenville property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Greenville crews follow on every job.
We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
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.
Because we're actually based near Greenville rather than routing calls through a national center, we can usually get someone out the same day you call.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
Filing a water damage claim in Greenville, WI can be confusing — we've done it enough times with Greenville adjusters to help you avoid common denials.
Every Greenville job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"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."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"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."
"Technician actually explained why the water was coming in instead of just quoting a number. First contractor who's done that for us."
Whether you're in the older, established parts of Greenville or a newer subdivision still settling, our crews have likely already worked on a foundation like yours nearby.
