Halo Water Proofing has been the Andover area's go-to call for Crawl Space Encapsulation because we answer the phone, show up on time, and stand behind the work.
We're Halo Water Proofing — a MN-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Andover-area foundations, and exactly how to stop it.
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.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Andover technicians hear about most often before an inspection.
Odor is often the first sign Andover customers notice, well before any visible water shows up.
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
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.
These signs upstairs are often the last clue Andover homeowners notice, even though the moisture issue started in the basement months earlier.
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.

We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
No verbal estimates that change later. What's quoted for your Andover job is what's invoiced.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
There's no verbal quote that magically grows once the crew arrives at your Andover property — the written estimate is the final word.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"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."
