Brick Replacement: Cost, Methods, and When to Replace Bricks

Not every worn-looking brick needs to come out, but some do. Knowing when brick replacement is the right call, and when repointing or patching will hold, saves Toronto property owners from either overspending on unnecessary work or underinvesting in a repair that fails within a season. At Automatic Masonry, we assess properties across Toronto and the GTA to give owners a clear answer on which approach is right.

This guide covers the situations that require new brickwork, the process involved, what drives the overall cost, and the specific circumstances that call for specialist approaches.

When Is It Necessary?

Repointing addresses failing mortar. Crack stitching stabilizes movement. But there are situations where the brick itself is the problem, and no amount of patching will hold.

Spalling and face loss. When the outer face of a brick has broken away due to freeze-thaw damage, the exposed inner material is too soft and porous to remain in service. There is no reliable way to restore it. The brick needs to come out.

Through-cracks in the brick body. Hairline cracks in mortar joints can be repointed. But a crack running directly through the brick itself means that brick has lost structural integrity. Leaving it in place creates a weak point that widens with each winter.

Rotten brick replacement. In older Toronto buildings exposed to persistent moisture, bricks can become saturated and begin to soften from the inside out. This is a common requirement at basement level, around grade foundations, and anywhere drainage has been inadequate over the years.

Failing window sills. Window sills receive a disproportionate share of water exposure. If the sill is not properly pitched to shed water away from the wall, saturation and decay follow. Brick window sill replacement is frequently needed where the original sill detail was inadequate or water has been pooling without attention.

Firebox deterioration. Firebox bricks are exposed to extreme heat cycles and combustion acids. Fireplace brick replacement requires refractory materials specifically rated for high-temperature use, not standard facing brick.

How the Process Works

Replacing brickwork is a skilled trade process. Matching the original material and executing the removal without disturbing surrounding courses takes experience and the right tools.

Assessment and Sourcing

Before work begins, a competent contractor will assess the scope and source matching bricks. Colour, texture, size, and porosity all affect how well a new brick integrates with the surrounding wall. In Toronto, where many properties use brick types no longer in production, finding a close match can take time. Using obviously mismatched material undermines both the visual result and, in some cases, structural compatibility. For heritage properties, our guide on heritage masonry restoration covers the specific challenges of working with original building materials.

Removal

Each brick is carefully cut and chiselled out without disturbing the surrounding courses. Rushing the removal can shift adjacent bricks and expand the scope of the job significantly.

Bedding and Jointing

The new brick is set in fresh mortar matched to the surrounding joints in strength and composition. On older buildings where lime-based mortars were originally used, matching the mortar correctly is essential. A mortar that is too rigid relative to the surrounding material will concentrate stress at the repair and cause further cracking.

Once set, joints are finished to match the original profile, and the surface is cleaned carefully for a consistent result.

What Affects Brick Replacement Cost?

Several variables determine what a project will cost in the GTA.

Number of bricks. A handful of isolated replacements is a very different scope from an entire course or section. The more bricks involved, the more labour and material the job requires.

Accessibility. Ground-level work is straightforward. Anything above the second storey requires scaffolding or lifts, which adds considerably to the total.

Brick sourcing. Standard modern brick is readily available. Matching a heritage type may require time and add to material costs.

Type of work. Work at the foundation level often involves more prep than facade repairs. Window sill and firebox repairs each carry their own material requirements and preparation steps.

Mortar matching. On heritage buildings, correctly matching mortar composition adds a step but is non-negotiable for a lasting result.

A reliable contractor will want to understand the full scope before quoting, whether through a site visit or a detailed photo assessment.

Frequently Asked Questions

How do I know if a brick needs to be replaced or just repointed?

If the mortar joints are failing but the bricks are intact, repointing is usually sufficient. If the bricks are cracked, spalling, or softening, replacement is the correct fix. A professional inspection will confirm which applies.

Can I find matching bricks for an older Toronto property?

In most cases, a close match can be sourced, though heritage types may take more time. Experienced local contractors typically have established suppliers and salvage sources. Searching for brick replacement contractors with heritage experience in your area is a good starting point.

What is involved in rotten brick replacement?

The process involves removing the deteriorated material, cleaning out the cavity, addressing any drainage issues, and bedding new bricks in compatible mortar. Simply fixing the surface without correcting the source of persistent moisture will lead to the same problem recurring.

Is fireplace brick replacement different from standard work?

Yes. Firebox applications require refractory brick rated for high temperatures and combustion acids. Standard facing brick is not suitable for these conditions. Make sure any contractor you hire specifies the correct materials.

How long does the work take?

A small number of isolated replacements can usually be completed in a day. More extensive work may take several days depending on scope and curing requirements.
