Halo Water Proofing has been the Markham area's go-to call for Basement Waterproofing because we answer the phone, show up on time, and stand behind the work.
Halo Water Proofing started as a small IL crew and grew because Markham 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 Markham 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 Markham technicians hear about most often before an inspection.
Odor is often the first sign Markham customers notice, well before any visible water shows up.
Hairline cracks can widen over a Markham winter's freeze-thaw cycle and become active leak points by spring.
Efflorescence is a clear sign that water is actively passing through your Markham 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.
This is one sign we tell Markham customers not to wait on — wall movement tends to progress rather than resolve on its own.
These signs upstairs are often the last clue Markham homeowners notice, even though the moisture issue started in the basement months earlier.
Every Markham property is different — soil, slope, foundation age, water table depth. We size the fix to the actual problem, not a one-size package.
Standing water in your basement doesn't wait for business hours, and neither do we. Our Markham emergency crews extract standing water first, then diagnose the entry point so it doesn't happen again next storm.
Call for Emergency Service →Hairline cracks are how most Markham 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 →Most sump pump failures we see in Markham happen during the exact storms that need them most — a battery backup closes that gap when the power drops.
Schedule a Pump Inspection →Some Markham 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 Markham crews encapsulate the space fully — floor, walls, and vents — so moisture stops migrating into your living areas.
Get a Crawl Space Quote →We work directly with Markham property managers and business owners on below-grade waterproofing, parking structure sealing, and large-scale drainage corrections — scheduled around your operating hours.

You call +1-866-476-1348 and talk to a real technician who asks the right questions to understand what's likely happening at your Markham property.
A technician inspects the Markham property in person, checking the foundation, drainage, grading, and any active moisture before recommending a fix.
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 Markham property — the written estimate is the final word.
Our trucks stage locally around Markham, which is why emergency calls typically get a technician on-site in under two hours, not "sometime tomorrow."
Our repairs come with written, transferable warranties — a real asset if you sell the Markham property later.
If your Markham basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
We can supply the photo documentation and repair scope most Markham, IL carriers ask for before approving a claim.
Our name is on trucks driving around Markham every day — we don't cut corners on a job our neighbors will see.
"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."
"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."
"Crawl space smelled awful for years. Encapsulation crew did a clean job and the smell is completely gone upstairs now."
"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."
