Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Andover property, gives you a straight answer, and fixes it right the first time.
Licensed & insured in MN · 24/7 dispatch
Halo Water Proofing started small in the Andover area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
Our Andover 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 Andover 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 Andover technician today, not an automated queue. We'll explain what's going on and get you scheduled.

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 Andover foundation rarely stay small — seasonal ground movement tends to widen them over time.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
This is one sign we tell Andover customers never to wait on — wall movement tends to progress, not resolve on its own.
Peeling paint near the floor upstairs is one of the last signs Andover homeowners connect to a basement problem.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Andover crews handle most.
Storm season keeps our Andover emergency line busy — active flooding always jumps ahead of routine inspections in the queue.
