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.
Every Lannon 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 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.
📞 +1-866-476-1348Most Lannon calls didn't start with a flood — they started with one of these small signs weeks or months earlier.
A musty smell usually means moisture is already moving through your Lannon basement, even if the floor looks bone dry.
Small cracks in a Lannon foundation rarely stay small — seasonal ground movement tends to widen them over time.

A Lannon 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 Lannon schedule.

From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Lannon crews handle most.
A flooded Lannon basement doesn't wait for morning, and neither do we. Our crews pull the standing water and start drying the space the same visit.
Get Emergency Help →Seasonal ground movement in Lannon tends to widen existing cracks over time, so sealing early usually costs less than waiting.

Book a Pump Check →For yards fighting bad grading, an exterior French drain intercepts water before it ever touches the foundation wall.

We've heard every Lannon horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
We're not routing your call through a national center — the person who answers is close by.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
If your Lannon basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We can supply the documentation most carriers ask for before approving a Lannon claim.

"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
