Halo Water Proofing is a IL-licensed Basement Waterproofing company that treats every Markham job like it's the only one on the schedule.
Every Markham technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.

📞 +1-866-476-1348Catching one of these early usually means a smaller repair bill and a lot less stress for Markham homeowners.
Odor is often the very first clue Markham homeowners notice, well before any water is visible.

If your pump only shuts off for a few minutes at a time, it's worth having it checked before it fails outright.
This is one sign we tell Markham customers never to wait on — wall movement tends to progress, not resolve on its own.

Whatever's going on with your Markham property, chances are we've already fixed something similar nearby this month.

Get Emergency Help →We seal active Markham foundation cracks with hydraulic cement injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →Already have a pump that's struggling? We'll test it honestly and tell you whether it needs replacing or just a tune-up.

Our crew completes the repair, cleans up, and walks you through the warranty on what was installed.
We've heard every Markham horror story about contractors who disappear mid-job or pad the invoice. Here's how we do it differently.
You get a real number before any work starts — what you approve is what you're billed.
We're not routing your call through a national center — the person who answers is close by.
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."
"Got three quotes for a crack repair. This was the only company that actually explained why the crack was happening instead of just naming a price."
"Our sump pump died during the worst storm of the year, obviously. Battery backup was installed the next day and we haven't worried since."
"Handled waterproofing for our parking structure with minimal disruption to tenants and stuck to the schedule."
"French drain install took two days exactly as quoted, and the yard looked better than before."
"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.
