Why Mortar Fails Over Time
Toronto’s Weather and Ageing Construction Can Weaken Brick Joints
Over time, exposure to moisture, temperature changes, and natural wear causes mortar joints to crack, shrink, or fall out. In Toronto and the GTA, freeze-thaw cycles are especially harsh on masonry, allowing water to enter gaps and damage the surrounding bricks. Homes built decades ago may also have outdated mortar mixes that deteriorate faster.
When mortar starts to fail, the structure becomes vulnerable. That’s where our repointing and tuckpointing services come in. Repointing involves removing the damaged mortar and applying new, properly matched mortar to restore the strength and stability of your brickwork. Tuckpointing takes it a step further with a decorative finish that improves the appearance of older or heritage properties.
We service all types of masonry in Toronto, Etobicoke, Scarborough, North York, Vaughan, and surrounding areas — helping homeowners extend the life of their walls, chimneys, steps, and facades with clean, professional repair work.
The Importance of Using Lime Mortar on Clay Brick
Breathable Mortar Means Longer-Lasting Masonry and Less Damage Over Time
Traditional clay bricks are designed to breathe — they naturally absorb and release moisture. That’s why we always use the proper lime-based mortar when repointing or tuckpointing older homes. Unlike modern cement mortars, lime mortar is softer and more flexible, allowing movement and moisture transfer without cracking the bricks.
Using the wrong type of mortar or sealing bricks with paint traps moisture inside the wall, which leads to spalling, crumbling, and costly damage. If your home was built with clay brick, especially in older Toronto neighbourhoods like High Park, East York, or The Annex, it’s critical to use lime mortar that respects the original building materials and allows the masonry to function properly. We specialize in using traditional techniques and breathable mortar mixes to preserve your home the right way.
