Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Markesan property, gives you a straight answer, and fixes it right the first time.
Background-checked Markesan technicians · Written pricing
Halo Water Proofing is a WI-licensed Exterior Waterproofing company that treats every Markesan job like it's the only one on the schedule.
We don't run a bidding war between crews. The Markesan technician who inspects your property is the same one who does the repair, start to finish.
Our Markesan 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 Markesan crews hear about most.
Odor is often the very first clue Markesan homeowners notice, well before any water is visible.
Small cracks in a Markesan 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.
This is one sign we tell Markesan customers never to wait on — wall movement tends to progress, not resolve on its own.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Markesan basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
A flooded Markesan basement doesn't wait for morning, and neither do we. Our crews pull the standing water and start drying the space the same visit.
Get Emergency Help →We seal active Markesan foundation cracks with epoxy injection — stopping the leak at its source instead of patching the surface.
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 →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.
Talk Drainage Options →A damp Markesan 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 Markesan jobs with written specs and a real timeline.
Request a Commercial Quote →No pressure, no scripts — just what actually happens once you call +1-866-476-1348.
We figure out fast whether this needs an emergency dispatch or a scheduled inspection.
No jargon, no pressure — just a clear look at what's actually going on.
Every Markesan 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.
We've heard every Markesan 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.
Our major repairs come with written, transferable warranties — useful if you sell the Markesan property later.
If your Markesan basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We photograph the damage and provide a written scope your insurance adjuster can actually use.
Our trucks are recognizable around Markesan — we don't cut corners on jobs our neighbors will see.
"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."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"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."
"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."
If a covered repair doesn't hold up, we come back and make it right — no arguing, no extra invoice. That's written into every Markesan contract we sign.
