Licensed & insured in WI · Real warranties
Halo Water Proofing started small in the Sullivan area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Every Sullivan 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 Sullivan 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.
Talk to a real Sullivan technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Most Sullivan calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
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.
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.
This is one sign we tell Sullivan customers never to wait on — wall movement tends to progress, not resolve on its own.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Sullivan basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
Get Emergency Help →Seasonal ground movement in Sullivan tends to widen existing cracks over time, so sealing early usually costs less than waiting.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.
Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
