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

Halo Water Proofing started as a small IL crew and grew because Mount Olive 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 Olive 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 Olive customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
Odor is often the first sign Mount Olive 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.
It's easy to dismiss efflorescence as harmless dust, but it actually signals active moisture movement through the wall.
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 Mount Olive 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 Mount Olive every day.
Storm season in Mount Olive, IL means our emergency line gets busy fast — we triage calls by severity so active flooding at your Mount Olive address jumps the queue ahead of routine inspections.
Call for Emergency Service →Hairline cracks are how most Mount Olive basements start leaking. We use hydraulic cement injection to seal the crack from the inside out, stopping the leak at the source instead of just painting over the symptom.
Get a Crack Assessment →Already have a sump pump that's failing or too small for your Mount Olive 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 Olive 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 Olive 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 Olive commercial projects around business hours or tenant schedules so operations aren't disrupted mid-project.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Mount Olive crews follow on every job.

"They came out the same afternoon I called about water coming in during a storm. Explained everything before they touched anything. Basement's been bone dry since."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Crawl space smelled awful for years. Encapsulation crew did a clean job and the smell is completely gone upstairs now."
"Managed our building's parking garage waterproofing project. Kept to the schedule, communicated well with tenants, minimal disruption."
"We had three foundation cracks and expected a huge bill. Turned out only one needed injection — they didn't try to sell us on the other two. That honesty is rare."
