Halo Water Proofing has been the Sun Prairie area's go-to call for Basement Waterproofing because we answer the phone, show up on time, and stand behind the work.
Halo Water Proofing started as a small WI crew and grew because Sun Prairie customers kept referring us to neighbors — that's still how most of our work comes in today.
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.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Sun Prairie technicians hear about most often before an inspection.
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.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Sun Prairie storm.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
These signs upstairs are often the last clue Sun Prairie homeowners notice, even though the moisture issue started in the basement months earlier.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Sun Prairie every day.
Storm season in Sun Prairie, WI means our emergency line gets busy fast — we triage calls by severity so active flooding at your Sun Prairie address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in Sun Prairie, 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 →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 →Older Sun Prairie homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →We work directly with Sun Prairie 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 Sun Prairie crews follow on every job.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"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."

"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."
