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

Halo Water Proofing started as a small NC crew and grew because Mount Pleasant 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 Mount Pleasant 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.
📞 +1-866-476-1348Most Mount Pleasant customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Hairline cracks can widen over a Mount Pleasant winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Mount Pleasant 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 Mount Pleasant lot's water table.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Mount Pleasant call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Mount Pleasant crews trace back to a drainage issue.
Every Mount Pleasant 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 Mount Pleasant basement floods, minutes matter for your drywall, flooring, and belongings. We dispatch a crew fast, pull the water, and start drying the space with commercial-grade equipment the same visit.
Call for Emergency Service →A cracked foundation wall isn't just a cosmetic issue — it's a water entry point and, over time, a structural one. Our Mount Pleasant crews assess whether it's a simple seal or a sign of bigger settlement issues before recommending a fix.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Mount Pleasant 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 Mount Pleasant 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 →Musty smell upstairs that you can't explain? It's usually the crawl space. Our Mount Pleasant crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We can phase larger Mount Pleasant commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
