Repointing is the structural workhorse of brick restoration. Unlike tuckpointing (which adds a decorative fine line), repointing focuses on one job: replacing failed mortar so your wall stops letting water in. It's the lower-cost option when aesthetics matter less than weather protection, and it's the right call for the majority of London Ontario homes.
What Is Repointing?
Repointing is the process of grinding out deteriorated mortar joints and refilling them with fresh mortar that matches the original mix in strength and colour. Done right, repointing extends the life of a brick wall by 30 to 50 years.
Repointing vs Tuckpointing
The two are often confused. Quick distinction:
- Repointingstructural mortar replacement. Joints match existing colour. Lower cost.
- Tuckpointingrepointing PLUS a thin contrasting line for visual sharpness. Higher cost, primarily aesthetic.
For most homeowners, repointing is what you actually need. See our tuckpointing page if you have a heritage facade where the contrasting line matters.
Signs Your Brick Home Needs Repointing
- Mortar that crumbles when scraped with a key
- Visible gaps or missing joints, water entry points
- White efflorescence on the brick face, moisture moving through the wall
- Cracks along the mortar line (not the brick face)
- Mortar dust accumulating at the base of the wall
- Damp spots inside on exterior walls
