Halo Water Proofing has been the Green Lake area's go-to call for Sump Pump Installation 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 Green Lake customers kept referring us to neighbors — that's still how most of our work comes in today.
Every technician on our Green Lake 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.
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.
📞 +1-866-476-1348Most Green Lake customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Stair-step cracks in block foundations are a common early warning sign we see across Green Lake-area homes.
Efflorescence is a clear sign that water is actively passing through your Green Lake foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Green Lake lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Green Lake 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 Green Lake every day.
Storm season in Green Lake, WI means our emergency line gets busy fast — we triage calls by severity so active flooding at your Green Lake address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in Green Lake, WI push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →A tired or undersized sump pump is the #1 reason we get emergency calls in Green Lake after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.

No verbal estimates that change later. What's quoted for your Green Lake job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
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.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
