We're Halo Water Proofing — a MN-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through New London-area foundations, and exactly how to stop it.

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 New London technicians hear about most often before an inspection.
Odor is often the first sign New London 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.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your New London lot's water table.
This is one sign we tell New London 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.
Every New London 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 New London, MN means our emergency line gets busy fast — we triage calls by severity so active flooding at your New London address jumps the queue ahead of routine inspections.
Call for Emergency Service →Freeze-thaw cycles in New London, 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 New London happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →Some New London 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 →Older New London homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →We work directly with New London property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.

You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
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 New London property — the written estimate is the final word.
Our trucks stage locally around New London, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
