From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Merrill before. We show up, we diagnose it straight, and we fix it right.

Halo Water Proofing started as a small WI crew and grew because Merrill customers kept referring us to neighbors — that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Merrill 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 Merrill 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 Merrill-area homes.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
A pump under constant strain tends to fail at the worst possible time — usually during the next big Merrill storm.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Merrill call we prioritize fast.
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 Merrill every day.
When your Merrill basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Hairline cracks are how most Merrill 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 Merrill after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Merrill basement floor — one of the most reliable long-term fixes we install.
Ask About Drain Systems →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Merrill crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →Commercial properties in Merrill carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.

You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Merrill property.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
No verbal estimates that change later. What's quoted for your Merrill job is what's invoiced.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
There's no verbal quote that magically grows once the crew arrives at your Merrill property — the written estimate is the final word.
Our trucks stage locally around Merrill, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
We can supply the photo documentation and repair scope most Merrill, WI carriers ask for before approving a claim.
Our name is on trucks driving around Merrill every day — we don't cut corners on a job our neighbors will see.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
"Crawl space smelled awful for years. Encapsulation crew did a clean job and the smell is completely gone upstairs now."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"French drain install took two days like they said it would, not five. Yard was put back together better than before."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
