Halo Water Proofing has been the Sun Prairie area's go-to call for Wet Basement Repair 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.
We don't send apprentices to figure it out on your dime. Every Sun Prairie 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.
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."
Hairline cracks can widen over a Sun Prairie winter's freeze-thaw cycle and become active leak points by spring.
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.
Flooring that's cupping or warping near an exterior wall is a common clue our Sun Prairie crews trace back to a drainage issue.
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.
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 battery backup units so your basement stays dry even if the power goes out mid-storm.

"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."
