Halo Water Proofing is a WI-licensed Interior Drainage System company that treats every Sun Prairie job like it's the only one on the schedule.
Every Sun Prairie technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Sun Prairie homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Sun Prairie homeowners.
Odor is often the very first clue Sun Prairie homeowners notice, well before any water is visible.
Small cracks in a Sun Prairie foundation rarely stay small — seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Sun Prairie basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Sun Prairie emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Seasonal ground movement in Sun Prairie tends to widen existing cracks over time, so sealing early usually costs less than waiting.

Request a Commercial Quote →Here's exactly what Sun Prairie customers can expect from first call to final walkthrough.
A real technician asks the right questions to understand what's likely happening at your Sun Prairie property before anyone drives out.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
We've heard every Sun Prairie horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Our major repairs come with written, transferable warranties — useful if you sell the Sun Prairie property later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
Filing a claim can be confusing — we've walked Sun Prairie customers through this process many times.
Every Sun Prairie job reflects on the next referral, so we treat each one like it matters.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Straightforward commercial quote, professional crew, no back and forth."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
Every Sun Prairie technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
