Masonry Repairs & Repointing in Mississauga & Ontario

Masonry in Ontario faces a brutal annual cycle: 100+ freeze-thaw events every winter, driving rain, road salt spray, and UV that bakes mortar dry in summer. The joints go first. Once the mortar sits recessed more than 6mm below the brick face, water pools in the wall rather than shedding off, and the slow failure of the whole structure begins.

Repointing, raking out the failed mortar to 25mm depth and rebuilding with a fresh, correctly-matched mix, is the single most effective restoration any masonry building can receive. Done properly, it buys 40 to 60 years of further life. Done badly (wrong mortar type, insufficient depth, brick faces chipped in the process) it accelerates the damage.

We match mortar by era. Pre-1920s homes built with soft red brick get a soft lime-based mortar that allows the wall to flex without cracking the brick faces. Modern homes in Mississauga with hard pressed brick get a Type S cement mix appropriate to the substrate. Getting this wrong is the most common mistake amateur masons make, and the one that causes brick-face spalling in winters to come.
