Licensed & insured in WI · 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 Grand Marsh 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 Grand Marsh 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.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Grand Marsh crews hear about most.
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.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Grand Marsh sump pump that never rests is usually undersized or nearing the end of its life.
This is one sign we tell Grand Marsh customers never to wait on — wall movement tends to progress, not resolve on its own.
Peeling paint near the floor upstairs is one of the last signs Grand Marsh homeowners connect to a basement problem.
No two Grand Marsh basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Grand Marsh emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
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 →Some Grand Marsh properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Older Grand Marsh homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.
Get a Crawl Space Quote →We can phase larger Grand Marsh commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.

"Straightforward commercial quote, professional crew, no back and forth."
