Halo Water Proofing has been the Duluth area's go-to call for Exterior Waterproofing because we answer the phone, show up on time, and stand behind the work.

Halo Water Proofing is a licensed and insured Exterior Waterproofing company built around one idea: show up when you say you will, explain the problem in plain language, and fix it so it stays fixed.

We don't send apprentices to figure it out on your dime. Every Duluth 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 Duluth technicians hear about most often before an inspection.
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 Duluth-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
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 Duluth 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 Duluth every day.
Storm season in Duluth, MN means our emergency line gets busy fast — we triage calls by severity so active flooding at your Duluth address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in Duluth, 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 Duluth happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →Some Duluth 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 Duluth 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 →We work directly with Duluth property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Duluth crews follow on every job.
You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Duluth property.

No verbal estimates that change later. What's quoted for your Duluth 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 Duluth property — the written estimate is the final word.
Our trucks stage locally around Duluth, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
