Halo Water Proofing has been the trusted call for Foundation Crack Repair across Markham because we answer the phone, show up when we say, and stand behind the work.
Background-checked Markham technicians · 24/7 dispatch
Halo Water Proofing started small in the Markham area and grew because customers kept referring us to their neighbors — that's still how most of our work comes in today.
We don't run a bidding war between crews. The Markham technician who inspects your property is the same one who does the repair, start to finish.
We've worked on foundations from decades-old Markham homes to brand-new builds still settling into their soil, so whatever your basement is dealing with, we've likely seen a version of it nearby.
Talk to a real Markham technician today, not an automated queue. We'll explain what's going on and get you scheduled.
📞 +1-866-476-1348Water problems build slowly before they become emergencies. These are the clues our Markham crews hear about most.
If the basement smells damp no matter the season, water is likely finding a way in somewhere you can't see.
Stair-step cracking in block foundations is one of the most common early signs our Markham crews see.
That white powder on basement walls is mineral residue left behind as water passes through the concrete.
A Markham sump pump that never rests is usually undersized or nearing the end of its life.
If a foundation wall looks like it's curving inward, that's beyond a simple patch and needs a real assessment.
Flooring that's cupping near an exterior wall often traces straight back to a basement moisture issue below.
No two Markham basements are the same — soil type, age of the home, water table. We match the fix to your actual problem.
Storm season keeps our Markham emergency line busy — active flooding always jumps ahead of routine inspections in the queue.

You'll talk to a person, not a script — enough of a conversation to know what to expect before anyone shows up.
A Markham technician walks the property, checks the foundation and drainage, and explains what's found in plain language.
The number you approve is the number you're billed — no change orders once the crew shows up.
Once the job's done, you get written proof of what was installed and exactly what the warranty covers.
We've heard every Markham horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
We quote the job in writing after seeing it in person, so there's no surprise on the final invoice.
A local dispatch model means the technician who answers your questions is the same one who shows up.
Our major repairs come with written, transferable warranties — useful if you sell the Markham property later.
Our technicians are trained to diagnose accurately, not to upsell — that changes the advice you actually get.
Filing a claim can be confusing — we've walked Markham customers through this process many times.
Every Markham job reflects on the next referral, so we treat each one like it matters.
"Woke up to a wet basement and had someone out by mid-morning. No pressure, no upsell, just fixed it."
"Fair price, on time, cleaned up after. Wish every contractor worked this way."
"Crawl space smelled bad for years. After encapsulation, the smell upstairs is completely gone."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"Expected a huge bill for three cracks, only one actually needed injection. Appreciated the honesty."
"Insurance claim was stressful until they stepped in with photos and a written scope. Approved within a week."
"Crew was respectful of our landscaping during the drain install and left the yard looking better than before they started."
Every Markham technician we send is background-checked and trained on the systems we install, so the crew that inspects your property is the same one that fixes it.
