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

We're Halo Water Proofing — a MI-licensed, fully insured waterproofing outfit that's spent years learning exactly how water moves through Corunna-area foundations, and exactly how to stop it.

We don't send apprentices to figure it out on your dime. Every Corunna 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.
📞 +1-866-476-1348Most Corunna 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 Corunna customers notice, well before any visible water shows up.
Hairline cracks can widen over a Corunna winter's freeze-thaw cycle and become active leak points by spring.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
If your pump is running around the clock instead of only during storms, it's worth having it evaluated before it fails completely.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
These signs upstairs are often the last clue Corunna homeowners notice, even though the moisture issue started in the basement months earlier.
Every Corunna property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Storm season in Corunna, MI means our emergency line gets busy fast — we triage calls by severity so active flooding at your Corunna address jumps the queue ahead of routine inspections.
Call for Emergency Service →Hairline cracks are how most Corunna basements start leaking. We use polyurethane 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 →Most sump pump failures we see in Corunna happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →For Corunna 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 →Older Corunna homes with vented crawl spaces are especially prone to seasonal moisture swings — encapsulation closes that off for good.
Get a Crawl Space Quote →Commercial properties in Corunna 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.

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.
Once the repair is done, you get documentation of the work and a written warranty — not just a handshake.
There's no verbal quote that magically grows once the crew arrives at your Corunna property — the written estimate is the final word.

If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
Our technicians are paid to diagnose correctly, not to upsell — that changes the advice you actually get on-site.

Every Corunna job reflects on the next referral, so we treat each one like it's the only advertising that matters.
"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."
"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."
"Straightforward commercial quote, no back-and-forth, crew was professional the whole project."
"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."
