Background-checked Sullivan technicians · 24/7 dispatch
Halo Water Proofing is a WI-licensed Emergency Waterproofing company that treats every Sullivan job like it's the only one on the schedule.
We don't run a bidding war between crews. The Sullivan technician who inspects your property is the same one who does the repair, start to finish.

One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Sullivan crews hear about most.
A musty smell usually means moisture is already moving through your Sullivan basement, even if the floor looks bone dry.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
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.
Peeling paint near the floor upstairs is one of the last signs Sullivan homeowners connect to a basement problem.
Whatever's going on with your Sullivan property, chances are we've already fixed something similar nearby this month.
A flooded Sullivan basement doesn't wait for morning, and neither do we. Our crews pull the standing water and start drying the space the same visit.

Every Sullivan 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."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
