Halo Water Proofing has been the Larsen area's go-to call for Wet Basement Repair because we answer the phone, show up on time, and stand behind the work.

Halo Water Proofing is a licensed and insured Wet Basement Repair company built around one idea: show up when you say you will, explain the problem in plain language, and fix it so it stays fixed.

We don't send apprentices to figure it out on your dime. Every Larsen 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.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Larsen technicians hear about most often before an inspection.
Odor is often the first sign Larsen customers notice, well before any visible water shows up.
Stair-step cracks in block foundations are a common early warning sign we see across Larsen-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Larsen storm.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Larsen every day.
When your Larsen basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew fast, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Hairline cracks are how most Larsen basements start leaking. We use epoxy injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Larsen after heavy rain. We install dual-pump systems so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →Some Larsen lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Larsen crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We work directly with Larsen property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Larsen 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 Larsen property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
No verbal estimates that change later. What's quoted for your Larsen job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
A local dispatch model means the technician who answers questions about your Larsen job is the same one who shows up to do it.
Our repairs come with written, transferable warranties — a real asset if you sell the Larsen property later.
If your Larsen basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We can supply the photo documentation and repair scope most Larsen, WI carriers ask for before approving a claim.
Our name is on trucks driving around Larsen every day — we don't cut corners on a job our neighbors will see.
"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
Whether you're in the older, established parts of Larsen or a newer subdivision still settling, our crews have likely already worked on a foundation like yours nearby.
