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.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +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.
Stair-step cracks in block foundations are a common early warning sign we see across Andover-area homes.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Andover property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
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.
Call for Emergency Service →Freeze-thaw cycles in Andover, MN push existing cracks wider every winter, which is why we recommend sealing them before they become an active leak rather than after.
Get a Crack Assessment →Most sump pump failures we see in Andover happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →An interior drain tile system channels water to a sump pump before it ever reaches your Andover basement floor — one of the most reliable long-term fixes we install.

We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
A technician inspects the Andover property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
No verbal estimates that change later. What's quoted for your Andover job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
Because we're actually based near Andover rather than routing calls through a national center, we can usually get someone out the same day you call.

We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Word of mouth is still how most Andover customers find us, which keeps our standards higher than a big out-of-town franchise.
"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
