Halo Water Proofing has been the Grand Marsh area's go-to call for Exterior Waterproofing because we answer the phone, show up on time, and stand behind the work.
We're Halo Water Proofing — a WI-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Grand Marsh-area foundations, and exactly how to stop it.
We don't send apprentices to figure it out on your dime. Every Grand Marsh job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Grand Marsh technicians hear about most often before an inspection.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Stair-step cracks in block foundations are a common early warning sign we see across Grand Marsh-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Grand Marsh lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Grand Marsh call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Grand Marsh crews trace back to a drainage issue.
Every Grand Marsh property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Grand Marsh emergency crews remove the water first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service →Freeze-thaw cycles in Grand Marsh, WI push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Grand Marsh lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →For Grand Marsh properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.

Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Grand Marsh crews follow on every job.
We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Grand Marsh property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
There's no verbal quote that magically grows once the crew arrives at your Grand Marsh property — the written estimate is the final word.
A local dispatch model means the technician who answers questions about your Grand Marsh job is the same one who shows up to do it.
