Foundation leaking? Basement smells off? Halo Water Proofing sends a real technician to your Markham property, gives you a straight answer, and fixes it right the first time.
Free, no-obligation estimates · Real warranties
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.
Every Markham technician we send is background-checked and trained on the exact equipment we install — not a subcontractor picked up for the day.
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.
Odor is often the very first clue Markham homeowners notice, well before any water is visible.
Stair-step cracking in block foundations is one of the most common early signs our Markham crews see.
It's easy to mistake efflorescence for harmless dust, but it actually signals active moisture movement.
A pump under constant strain tends to fail during the exact storm that needs it most.
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.
A flooded Markham basement doesn't wait for morning, and neither do we. Our crews get it out and start drying the space the same visit.
Get Emergency Help →We seal active Markham foundation cracks with polyurethane injection — stopping the leak at its source instead of patching the surface.
Ask About Crack Repair →A failed sump pump is the top reason for emergency calls across Markham after heavy rain — we install pumps sized to your actual water volume, plus battery backup for power outages.
Book a Pump Check →An interior drain tile system routes water to a sump pump before it reaches your Markham basement floor at all.

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."

"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."
