Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Lannon property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in WI · Real warranties
Halo Water Proofing started small in the Lannon area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Lannon crew leads have handled repairs like yours dozens of times before, and a supervisor signs off before we call any job finished.
We've worked on foundations from decades-old Lannon 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 Lannon technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Lannon crews hear about most.
Odor is often the very first clue Lannon homeowners notice, well before any water is visible.
Small cracks in a Lannon foundation rarely stay small — seasonal ground movement tends to widen them over time.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
This is one sign we tell Lannon 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.
Whatever's going on with your Lannon property, chances are we've already fixed something similar nearby this month.
Storm season keeps our Lannon emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
Get Emergency Help →Seasonal ground movement in Lannon tends to widen existing cracks over time, so sealing early usually costs less than waiting.
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 →Older Lannon homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.

Every Lannon job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"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."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"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."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
Every Lannon technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
