Background-checked Sullivan technicians · Real warranties
Halo Water Proofing is a WI-licensed Exterior Waterproofing company that treats every Sullivan job like it's the only one on the schedule.
Our Sullivan crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.

One phone call gets you a straight answer and a real appointment — not a vague callback promise.

Odor is often the very first clue Sullivan homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
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.
Whatever's going on with your Sullivan property, chances are we've already fixed something similar nearby this month.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
