Background-checked Larsen technicians · Written pricing
Halo Water Proofing is a WI-licensed Sump Pump Installation 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.
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 Larsen 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 Larsen foundation rarely stay small — seasonal ground movement tends to widen them over time.
Efflorescence is a reliable early sign that water is moving through your Larsen foundation wall right now.
A Larsen sump pump that never rests is usually undersized or nearing the end of its life.
A wall that's starting to bow is a structural issue on top of a water issue — this jumps to the front of our Larsen schedule.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Larsen crews handle most.
Storm season keeps our Larsen emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →We seal active Larsen foundation cracks with polyurethane injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Most Larsen pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →Some Larsen properties need both systems working together — we'll say so honestly instead of selling just one.
Talk Drainage Options →A damp Larsen 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 →We can phase larger Larsen commercial projects around business hours or tenant schedules so operations keep running.
Request a Commercial Quote →Here's exactly what Larsen customers can expect from first call to final walkthrough.
