Halo Water Proofing has been the Sun Prairie area's go-to call for Foundation Crack Repair 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 Sun Prairie-area foundations, and exactly how to stop it.

Every technician on our Sun Prairie 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.
📞 +1-866-476-1348Most Sun Prairie customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
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 Sun Prairie 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 Sun Prairie lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Sun Prairie call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Sun Prairie 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 Sun Prairie emergency crews remove the water first, then diagnose the source 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 Sun Prairie crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Sun Prairie after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Sun Prairie basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Sun Prairie 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 Sun Prairie 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 Sun Prairie 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.
No verbal estimates that change later. What's quoted for your Sun Prairie job is what's invoiced.
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.
A local dispatch model means the technician who answers questions about your Sun Prairie job is the same one who shows up to do it.
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.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Word of mouth is still how most Sun Prairie 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."
"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."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
