Halo Water Proofing has been the Markesan 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 started as a small WI crew and grew because Markesan customers kept referring us to neighbors — that's still how most of our work comes in today.
Every technician on our Markesan crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Markesan customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Markesan customers notice, well before any visible water shows up.
Hairline cracks can widen over a Markesan winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Markesan foundation wall, even if you've never seen standing water.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Markesan call we prioritize fast.
These signs upstairs are often the last clue Markesan homeowners notice, even though the moisture issue started in the basement months earlier.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Markesan every day.
Storm season in Markesan, WI means our emergency line gets busy fast — we triage calls by severity so active flooding at your Markesan address jumps the queue ahead of routine inspections.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Markesan crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Markesan lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →Some Markesan 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 →Older Markesan homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.

Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Markesan crews follow on every job.

Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.

Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
