Chimney Rebuilds
A failing chimney doesn't stay contained, it takes your roof, ceilings, and appliances with it, and it fails fast once it starts. Most masons patch it and leave. We rebuild it once, to last, brick matched to your home so it's actually solved
A chimney rebuild is the full dismantling and reconstruction of a chimney when the masonry has deteriorated past the point a repair can hold.
Most Toronto chimneys were built in the 1890s–1960s: soft brick, lime mortar, no liner. Under freeze-thaw, that combination doesn't fail gradually, it fails exponentially. Water gets in faster than the chimney can dry, each freeze widens the gap, more water gets in. A chimney sound for eighty years can be unsafe within three winters, often with no warning until a lean, a crack, or a ceiling stain shows up, by which point the damage has usually spread to the roof deck and interior.
We recommend against partial rebuilds. The brick just below visible damage is almost always near the end of its own life, and scaffolding and access cost the same whether we replace ten courses or the whole stack. So a partial repair just delays the same job at a worse price. Every rebuild is full, to code, with a 10-year structural warranty.
- The chimney has visibly shifted or pulled away from the house
- More than 30% of mortar joints have eroded past 1 cm on any face
- Brick is spalling, crumbling, or shedding loose material at the roofline
- Missing courses or stepped cracking are visible from the roof
- Prior repairs have failed twice or more within five years
- Water is entering the attic or upper rooms through the chimney chase
We follow the same written process on every rebuild. No surprises on scope, schedule, or price.
Assessment
Full inspection, cap to base, written scope before any work starts. Drone photography where roofline access is limited.
Material match
Brick sourced and matched to your home's existing colour, texture, and joint profile — confirmed before scheduling.
Deconstruction
Fully dismantled. Contained dust and debris, no slurry in your yard or eaves.
Rebuild
Laid to Ontario Building Code with matched mortar, finished to read as original to the house. Liner installed concurrently where required.
Structural warranty
Written on every rebuild
Liner warranty
When installed concurrently
Brick & mortar matching available
Colour and texture assessed on-site
Isolated, surface-level mortar erosion is repairable. Structural movement, missing courses, or brick failing across multiple faces means a repair won't hold, and we recommend a rebuild. We document both with photos before you decide.
Because the brick below the damaged section is almost always near the end of its life too, even where it looks fine. A partial rebuild fixes the visible problem and leaves the same failure to happen again in a few years, at the same access cost you already paid once. A full rebuild costs more up front and less over ten years.
Usually, Toronto was/is built with a fairly consistent set of regional brick types from the late 1800's to the present day. A large portion of Toronto's old housing stock has modern brick equivalents that look close enough that they wouldn’t be noticeable from the ground.
If you’d like a closer match, we can source original reclaimed materials from the same time period the structure was originally built. This ensures sizing, composition, weathering, and patina all remain congruent with the rest of the structure.
Depends on chimney height, access, and brick type. You can expect anywhere from $25-$100 per brick.
Standard chimney's less than 48hrs. As project complexity increases, so does the timeline.
A structurally compromised chimney is often flagged during insurance renewals or a home sale. A rebuilt chimney with a documented warranty and building-code compliance can clear those flags. We provide a written completion report for your insurer on request.
Not usually. We need access to the property and, if there's a connected fireplace, to the firebox. You get a start time and a daily check-in, and scaffolding and equipment are secured each evening.
Built once. Built right.
