Foundation Repairs
Repairing Cracked and Crumbling Foundation Walls
A foundation wall can fail slowly. Poured concrete cracks as it shrinks or as the soil around it shifts, concrete block opens along its mortar joints, and the stone foundations found under many older Toronto houses lose mortar until stones loosen. Freeze-thaw cycles widen every gap a little more each winter, and road salt splashed against the wall beside a driveway speeds up the damage to parging and masonry above grade.
Toronto Roofing & Masonry repairs foundation walls with the method that suits the material and the cause. That can mean sealing a leaking crack, repointing failed joints, rebuilding loose sections of stone or block, or replacing parging that has come away. Where settling or water is behind the damage, we tell you, explain the options that suit your home and give you an estimate before work starts.

Why choose us
Why Choose Us for Your Foundation Repair
Matched to the Material
Stone, block and poured concrete each fail differently, so the repair is chosen for the wall you have rather than one method for every house.
Settling Explained Clearly
If a crack suggests movement, we explain what the pattern shows and what it means for the repair before you commit to anything.
Outside Causes Considered
Where water or poor grading is feeding the damage, we point it out so the repaired wall is not left facing the same pressure.
Masonry Skills on Hand
Repointing, stonework and parging draw on the same masonry skills we use on chimneys and steps, so older foundations get a suitable mortar and finish.
