Background-checked Larsen technicians · 24/7 dispatch
Halo Water Proofing is a WI-licensed Emergency Waterproofing company that treats every Larsen job like it's the only one on the schedule.
Every Larsen technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
We've worked on foundations from decades-old Larsen homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
Talk to a real Larsen technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Most Larsen calls didn't start with a flood — they started with one of these small signs weeks or months earlier.

That white powder on basement walls is mineral residue left behind as water passes through the concrete.

These upstairs clues usually show up months after the basement moisture problem actually started.

Ask About Crack Repair →Most Larsen pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
