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.
Background-checked Andover technicians · Written pricing
Halo Water Proofing is a MN-licensed Foundation Crack Repair company that treats every Andover job like it's the only one on the schedule.
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.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Andover crews hear about most.
Odor is often the very first clue Andover homeowners notice, well before any water is visible.
A crack that wasn't there last year is worth a look before it becomes an active leak point.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A Andover sump pump that never rests is usually undersized or nearing the end of its life.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
From a 2 a.m. sump pump failure to a planned exterior drainage project, here's what our Andover crews handle most.
When water shows up fast, we move fast — extraction, drying equipment, and a plan to stop it from happening again.
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 →An interior drain tile system routes water to a sump pump before it reaches your Andover basement floor at all.
Talk Drainage Options →Older Andover homes with vented crawl spaces see the biggest swings in seasonal humidity — encapsulation closes that off for good.

No verbal number that quietly grows once the truck pulls up — the written quote is the final word.
You get documentation of the work plus a real warranty — not just a handshake.
We've heard every Andover horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
There's no verbal quote that grows once the crew shows up — the written estimate is final.
Our crews stage locally near Andover, which is why most emergency calls get a technician on-site in under two hours.
If a covered repair fails, we come back and fix it. That's part of the contract, not just a promise.
If your Andover basement just needs a small crack seal instead of a full system, that's exactly what we'll tell you.
We can supply the documentation most carriers ask for before approving a Andover claim.
Every Andover job reflects on the next referral, so we treat each one like it matters.
"Called during a storm and had a tech at my door within two hours. Explained everything before touching anything — basement's been dry since."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"First contractor who actually explained where the water was coming from instead of just quoting a number."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
We back our Andover work with real, transferable warranties because we plan to be here long after the job is done, not just for the one visit.
