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.
Every Andover 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 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.
One phone call gets you a straight answer and a real appointment — not a vague callback promise.

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.
Efflorescence is a reliable early sign that water is moving through your Andover foundation wall right now.
A Andover sump pump that never rests is usually undersized or nearing the end of its life.

Get Emergency Help →Not every crack means a structural problem, but every crack deserves a real look. We'll tell you which kind yours is.
Ask About Crack Repair →Most Andover pump failures happen during the exact storms that need them most, which is exactly why battery backup matters.
Book a Pump Check →Some Andover properties need both systems working together — we'll say so honestly instead of selling just one.

"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
