From a hairline crack to a fully soaked crawl space, our Green Lake crew has seen it and fixed it. No guesswork, no scare tactics — just a clear plan and a fair price.
Licensed & insured in WI · 24/7 dispatch
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.
Our Green Lake crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
We've worked on foundations from decades-old Green Lake 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.
📞 +1-866-476-1348Most Green Lake calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Green Lake basement, even if the floor looks bone dry.
Stair-step cracking in block foundations is one of the most common early signs our Green Lake crews see.
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 Green Lake 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.
Whatever's going on with your Green Lake property, chances are we've already fixed something similar nearby this month.
A flooded Green Lake basement doesn't wait for morning, and neither do we. Our crews extract it fast and start drying the space the same visit.

Every Green Lake 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."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Sump pump inspection was thorough and they didn't try to sell me a new one when mine just needed a part replaced."
We back our Green Lake work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
