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

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

Every technician on our Westerville crew is background-checked, factory-trained on the equipment we install, and held to the same estimate we quote you over the phone — no upsell surprises when the truck pulls up.
One call gets you a straight answer and a real appointment window — not a call-back promise.
📞 +1-866-476-1348Most Westerville customers didn't wake up one day with a flooded basement. It usually started small. These are the early signs worth calling about.
If the basement smells damp even when it looks dry, moisture is likely moving through the walls or floor somewhere.
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 Westerville foundation wall, even if you've never seen standing water.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
A bowing basement wall is a structural concern in addition to a water one — this is the kind of Westerville call we prioritize fast.
Flooring that's cupping or warping near an exterior wall is a common clue our Westerville crews trace back to a drainage issue.
From an emergency pump swap at 2 a.m. to a full exterior drainage system, this is the work we do in Westerville every day.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Westerville emergency crews pump out the basement first, then diagnose the source so it doesn't happen again next storm.
Call for Emergency Service →Hairline cracks are how most Westerville basements start leaking. We use epoxy 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 →A tired or undersized sump pump is the #1 reason we get emergency calls in Westerville after heavy rain. We install dual-pump systems so your basement stays dry even if the power goes out mid-storm.
Schedule a Pump Inspection →Some Westerville 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 Westerville 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 Westerville property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.
Request a Commercial Quote →No confusing steps, no hard sell — just the same process our Westerville crews follow on every job.
We start with a phone conversation, not a script — enough to know whether this is an emergency dispatch or a scheduled inspection.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
You receive a written, itemized quote before any work begins — the number you approve is the number you're billed.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
You get a written number before any work begins — the price you approve is the price you pay, no change-order games.
Our trucks stage locally around Westerville, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Warranty terms are explained before you sign, in plain language, so there's no fine print surprise if you ever need to use it.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.
We document the damage with photos and a written scope your insurance adjuster can actually use, and we'll walk you through the claim process.
Every Westerville job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"Called at 6am with a flooded basement and had a tech at my door by 8. No runaround, no upsell — just fixed it."
"Fair price, showed up on time, cleaned up after themselves. Wish more contractors worked like this."
"Our old sump pump died during the worst storm of the year, obviously. They had a battery backup system installed within a day. Haven't worried about it since."
"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."
"Insurance claim was a headache until they stepped in with photos and a written scope. Adjuster approved it within a week after that."
