Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Theresa property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in WI · Written pricing
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.
Every Theresa technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
Our Theresa 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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Theresa crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Small cracks in a Theresa foundation rarely stay small — seasonal ground movement tends to widen them over time.
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.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Theresa basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Theresa 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 →Most Theresa pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your Theresa basement floor at all.
Talk Drainage Options →A damp Theresa crawl space drives up humidity throughout the house — we seal it completely with heavy-duty vapor barrier and add dehumidification where needed.
Get a Crawl Space Quote →Commercial water intrusion means bigger stakes — inventory, tenants, downtime. We scope commercial Theresa jobs with written specs and a real timeline.
Request a Commercial Quote →Here's exactly what Theresa customers can expect from first call to final walkthrough.
You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
We point out exactly what we find as we find it, so nothing about the diagnosis feels like a black box.
Every Theresa quote is written before work starts, not estimated verbally and adjusted later.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
Plenty of companies advertise Wet Basement Repair in Theresa — here's what actually separates the ones worth calling from the ones that aren't.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Our major repairs come with written, transferable warranties — useful if you sell the Theresa property later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Every Theresa job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"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."
"Straightforward commercial quote, professional crew, no back and forth."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
Every Theresa 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.
