Repointing you can actually trust
Mortar is designed to be the sacrificial element — it should fail before the brick does. We rake joints to 3/4 inch, match mortar type and colour to the original, and tool the joint profile to shed water, which is what stops the freeze-thaw cycle that eventually forces a rebuild.
Every St. Catharines technician is WETT SITE-Basic certified at minimum, with two inspectors carrying full SITE-Comprehensive credentials.

Repointing in St. Catharines — common questions
How often does a chimney need repointing?+
Most GTA chimneys need repointing every 20–30 years. Exposed above-roof sections on the weather side often go first, at 15–20 years.
What does chimney repointing cost?+
Above-roof repointing runs $690–$2,400 depending on height, access, and how much of the stack is affected.
Can hard mortar damage old brick?+
Yes. Using type-S or portland-rich mortar on soft heritage brick forces moisture through the brick face and spalls it. Soft brick needs a lime-based mix.
