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.
