From a hairline foundation crack to a fully flooded crawl space, Halo Water Proofing has handled it in Appleton before. We show up, we diagnose it straight, and we fix it right.

Halo Water Proofing started as a small WI crew and grew because Appleton customers kept referring us to neighbors β that's still how most of our work comes in today.

We don't send apprentices to figure it out on your dime. Every Appleton 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 β not a call-back promise.
π +1-866-476-1348Water problems rarely announce themselves all at once β they usually show up as small clues first. Here's what our Appleton 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 β they rarely stay small once seasonal ground movement gets involved.
That white chalky film on basement walls is efflorescence β 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 Appleton lot's water table.
A bowing basement wall is a structural concern in addition to a water one β this is the kind of Appleton call we prioritize fast.
Peeling paint low on a basement wall or warped baseboards upstairs often trace back to moisture migrating up from below.
Every Appleton property is different β soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your Appleton basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew immediately, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service βFreeze-thaw cycles in Appleton, WI 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 βMost sump pump failures we see in Appleton happen during the exact storms that need them most β a battery backup closes that gap when the power drops.
Schedule a Pump Inspection βFor Appleton properties fighting grading or drainage issues, an exterior French drain can intercept water before it ever reaches the foundation wall at all. We map your yard's slope and water flow before recommending which approach fits.
Ask About Drain Systems βMusty smell upstairs that you can't explain? It's usually the crawl space. Our Appleton crews encapsulate the space fully β floor, walls, and vents β so moisture stops migrating into your living areas.
Get a Crawl Space Quote βCommercial properties in Appleton 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.
