From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Andover before. We show up, we diagnose it straight, and we fix it right.
Halo Water Proofing started as a small MN crew and grew because Andover customers kept referring us to neighbors — that's still how most of our work comes in today.
We don't send apprentices to figure it out on your dime. Every Andover job is run by a technician who has done this exact repair dozens of times, with a supervisor who signs off before we call it finished.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Most Andover customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
Hairline cracks can widen over a Andover winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Andover foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Andover lot's water table.
This is one sign we tell Andover customers not to wait on — wall movement tends to progress rather than resolve on its own.
Flooring that's cupping or warping near an exterior wall is a common clue our Andover crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Andover every day.
Storm season in Andover, MN means our emergency line gets busy fast — we triage calls by severity so active flooding at your Andover address jumps the queue ahead of routine inspections.
