Licensed & insured in WI ยท Written pricing

We built Halo Water Proofing around a simple promise: show up when we say, tell you the truth about what's wrong, and fix it so it stays fixed.
Every Sun Prairie technician we send is background-checked and trained on the exact equipment we install โ not a subcontractor picked up for the day.
Our Sun Prairie crew leads carry years of hands-on repair experience, not just sales training โ which is why the advice you get on-site tends to match what actually needs fixing.
One phone call gets you a straight answer and a real appointment โ not a vague callback promise.

If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your Sun Prairie foundation wall right now.
