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.
Every technician on our Andover crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
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.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Even small cracks are worth a second look — they rarely stay small once seasonal ground movement gets involved.
Efflorescence is a clear sign that water is actively passing through your Andover foundation wall, even if you've never seen standing water.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
This is one sign we tell Andover customers not to wait on — wall movement tends to progress rather than resolve on its own.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
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.
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 →A tired or undersized sump pump is the #1 reason we get emergency calls in Andover after heavy rain. We install right-sized primary pumps so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →Some Andover lots need both an interior and exterior system working together — we'll tell you honestly if that's the case rather than selling just one.
Ask About Drain Systems →A damp, uninsulated crawl space under a Andover home drives up humidity, invites mold, and wastes energy year-round. We seal it with heavy-duty vapor barrier, address any standing moisture, and can add dehumidification if needed.
Get a Crawl Space Quote →Commercial properties in Andover carry bigger stakes when water gets in: inventory, tenants, downtime. We scope commercial jobs with the same crew leads who run our residential work, backed by written specs and timelines.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Andover crews follow on every job.
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.

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.
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.
Our repairs come with written, transferable warranties — a real asset if you sell the Andover property later.
We'd rather earn a repeat customer with an honest small fix than push a system you don't need.
