Tuckpointing and repointing in Toronto
Mortar does not last as long as brick. On a typical Toronto home, mortar joints start deteriorating after 25 to 30 years. Freeze-thaw cycles crack them, rain washes them out, and eventually you can poke mortar out with your finger. Once the joints go, water gets behind the brick, and that is when the real damage starts — spalling brick, rotting framing, interior moisture problems.
Tuckpointing and repointing fix this by removing the old mortar and replacing it with fresh mortar. We do this work across the GTA on homes, commercial buildings, and heritage properties.
Tuckpointing vs. repointing
The terms get used interchangeably, but they mean different things. Repointing is the standard repair: grind out the damaged mortar to a depth of about 20 mm and pack in new mortar. The new mortar matches the existing colour and joint profile as closely as possible.
Tuckpointing is a decorative technique that goes a step further. After filling the joint with mortar that matches the brick colour, a thin line of contrasting mortar (usually white or cream) is applied along the centre of the joint. This creates the visual illusion of very fine, precise joints. It was common on Victorian-era brick buildings and is still used in heritage restoration.
Both processes protect the wall the same way. The difference is cosmetic.
Why it matters
Mortar joints are the weak point in any brick wall. They are designed to be the sacrificial element — the mortar absorbs moisture and freeze-thaw stress so the brick does not have to. But once the mortar fails, all that stress transfers to the brick. That is when spalling starts.
Repointing early, while the mortar is just cracked or recessed, costs a fraction of what brick replacement costs after the damage has spread. A few hundred dollars per section now versus thousands later.
Chimney tuckpointing
Chimneys are usually the first part of the house to need repointing. They sit above the roofline, exposed to wind and rain from all sides. The mortar deteriorates faster up there than anywhere else on the building.
We repoint chimneys regularly as part of our chimney repair work. Often the chimney needs repointing plus a new cap, new flashing, or crown repair — we handle all of it in one visit.
Signs you need tuckpointing
Walk around your house and look at the mortar joints. Here is what to watch for:
- Mortar that is cracked, crumbling, or recessed more than a few millimetres from the brick face
- Mortar you can scrape out with a key or screwdriver
- Gaps between the mortar and the brick — especially visible on horizontal joints
- White staining on the brick (efflorescence) — a sign that water is moving through the wall
- Damp spots or peeling paint on interior walls near the brickwork
If you see any of these, it is time to get the joints looked at. Earlier is cheaper.
Mortar matching
Getting the mortar colour right matters. A fresh bright white joint on a 60-year-old wall with weathered grey mortar looks patched, not repaired. We match the mortar colour to the existing joints as closely as possible — both the dry colour and the cured colour, which can be different.
The mortar type matters too. On heritage buildings built before the 1920s, the original mortar was lime-based. Using modern Portland cement mortar on these buildings is a mistake — it is too hard, traps moisture, and cracks the old soft brick instead of the joint. We use lime mortar on these properties.
Our process
We start by inspecting the wall and identifying which areas need repointing. Sometimes it is a few sections; sometimes it is the entire elevation. We quote by area, so you know exactly what you are paying for.
The old mortar gets ground out with a grinder or cut out by hand, depending on the joint size and the brick condition. We clean the joints, dampen them, and pack in fresh mortar in layers. The final step is tooling the joint to match the existing profile — concave, flush, raked, or struck depending on the original style.
We work section by section, scaffolding as needed. Cleanup happens daily.
Why hire a professional
Repointing looks simple, but doing it wrong causes more damage than doing nothing. Grinding too deep cuts into the brick face. Using the wrong mortar type traps moisture. Sloppy joint profiles look bad and do not shed water properly.
The mortar mix, the grinding depth, the joint profile, the curing conditions — all of these affect how long the repair lasts. Our masons have been doing this for years and know how to get it right the first time.
What a project looks like
A small residential job — one elevation of a two-storey house — usually takes two to three days. Larger projects, full-house repointing, or commercial buildings take proportionally longer. We schedule work in dry weather; mortar needs proper curing conditions to achieve full strength.
We set up scaffolding or work from ladders depending on the height. Drop cloths protect landscaping and walkways below. When we leave, the wall looks right and the mortar is sound.

What causes mortar to deteriorate?
Moisture, freezing, poor installation, or incompatible mortar mix.
Do all mortar joints need to be replaced?
Only damaged mortar is removed, unless full repointing is required.
