Wet basement? Cracked foundation? A Halo Water Proofing crew can be at your Markham property within hours — upfront pricing, no guesswork, no pressure.
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.
A musty smell in the basement or crawl space is usually moisture you can't see yet, not just "old house smell."
Stair-step cracks in block foundations are a common early warning sign we see across Markham-area homes.
That white chalky film on basement walls is efflorescence — mineral deposits left behind as water evaporates through concrete.
A sump pump that never stops cycling is often working harder than it should, or is undersized for your Markham lot's water table.
If a foundation wall looks like it's leaning or bulging inward, that's beyond a simple seal and needs a full assessment.
Flooring that's cupping or warping near an exterior wall is a common clue our Markham crews trace back to a drainage issue.
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.
When your Markham 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 →Hairline cracks are how most Markham 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 →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 →An interior drain tile system channels water to a sump pump before it ever reaches your Markham basement floor — one of the most reliable long-term fixes we install.
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.
We walk the space with you, point out what we find, and explain it in plain language — no jargon, no pressure.
No verbal estimates that change later. What's quoted for your Markham job is what's invoiced.
Our crew completes the work, cleans up the site, and walks you through the warranty coverage on what was installed.
We quote the job in writing after inspecting it in person, so what you agree to on the phone or at your door is what shows up on the final invoice.
A local dispatch model means the technician who answers questions about your Markham job is the same one who shows up to do it.
If a covered repair fails, we come back and make it right. That's written into every contract, not just promised on the phone.
If your Markham basement just needs a $200 crack seal instead of a $12,000 system, that's what we'll tell you.
Filing a water damage claim in Markham, IL can be confusing — we've done it enough times with Markham adjusters to help you avoid common denials.
