Halo Water Proofing has been the trusted call for Exterior Waterproofing across Windsor because we answer the phone, show up when we say, and stand behind the work.
Licensed & insured in WI · 24/7 dispatch
Halo Water Proofing started small in the Windsor area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Windsor crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
Our Windsor crew leads carry years of hands-on repair experience, not just sales training — which is why the advice you get on-site tends to match what actually needs fixing.
Talk to a real Windsor technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Most Windsor calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
Odor is often the very first clue Windsor homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
Efflorescence is a reliable early sign that water is moving through your Windsor foundation wall right now.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Windsor schedule.
These upstairs clues usually show up months after the basement moisture problem actually started.
No two Windsor basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Windsor 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 Windsor properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →Musty smell upstairs with no obvious source? Check the crawl space first — it's usually the culprit.
Get a Crawl Space Quote →We handle below-grade waterproofing for Windsor property managers and business owners, scheduled around your operating hours to limit disruption.

A real technician asks the right questions to understand what's likely happening at your Windsor property before anyone drives out.
No jargon, no pressure — just a clear look at what's actually going on.
No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Windsor horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
A local dispatch model means the technician who answers your questions is the same one who shows up.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
We'd rather earn a repeat Windsor customer with an honest fix than push a system you don't need.
Filing a claim can be confusing — we've walked Windsor customers through this process many times.
Word of mouth is still how most Windsor customers find us, which keeps our standards high.
"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."
Every Windsor technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
