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

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

We don't send apprentices to figure it out on your dime. Every Mendon 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.
Call now and talk to an actual technician, not a script. We'll walk you through what's likely going on and get a crew scheduled.
📞 +1-866-476-1348Water problems rarely announce themselves all at once — they usually show up as small clues first. Here's what our Mendon 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 Mendon foundation wall, even if you've never seen standing water.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Mendon lot's water table.
This is one sign we tell Mendon customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Mendon homeowners notice, even though the moisture issue started in the basement months earlier.
Every Mendon property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
When your Mendon basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew around the clock, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →Freeze-thaw cycles in Mendon, MI 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 →Already have a sump pump that's failing or too small for your Mendon lot? We'll test it, tell you honestly whether it needs replacing, and size the new one to your actual water volume — not the cheapest unit on the truck.
Schedule a Pump Inspection →Some Mendon 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 Mendon homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.

"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Got quotes from three companies for a crack repair. These guys were the only ones who actually explained why the crack was happening instead of just quoting a price."
