Chimney repair and rebuild in Toronto
Chimneys take more punishment than any other part of a house. They sit above the roofline, fully exposed to wind, rain, snow, and freeze-thaw cycles. The mortar joints erode, the brick spalls, the cap cracks, the flashing separates from the roof. Eventually, water gets inside the chimney structure and the damage accelerates.
We repair and rebuild chimneys across the Greater Toronto Area. Residential and commercial. From repointing a few deteriorated joints to a full chimney teardown and rebuild from the roofline up.
Common chimney problems
Most chimney issues we see in the GTA come down to water getting where it should not be:
- Cracked or missing mortar joints — the most common problem, and the starting point for most chimney damage
- Spalling brick — surface flaking caused by moisture freezing inside the brick
- Cracked or missing chimney cap — allows rain and snow directly into the flue
- Failed flashing — the seal where the chimney meets the roof separates, letting water into the attic and wall cavity
- Deteriorated flue liner — cracks in the liner let heat and gases escape into the chimney structure
- Leaning or shifting chimney — usually caused by foundation settlement or failed mortar on one side
Catching any of these early is cheaper than waiting. A few hundred dollars in repointing now can save thousands in rebuild costs later.
What we repair
Our chimney work covers the full range:
- Tuckpointing — grinding out old mortar and replacing it with fresh, colour-matched mortar
- Brick replacement — removing damaged bricks and setting matching new ones
- Chimney cap repair and replacement — concrete or metal caps that keep water and animals out
- Flashing repair — resealing the junction between chimney and roof
- Crown repair — fixing the sloped concrete or mortar top of the chimney
- Full chimney rebuild — tearing down the damaged section (usually above the roofline) and rebuilding with new brick and mortar
- Flue liner installation — stainless steel or clay tile liners
How we inspect chimneys
We start with a visual inspection from the ground and the roof. We look at the mortar joints, brick condition, cap, crown, and flashing. If the chimney is actively leaking, we check inside the attic space for water damage and trace it back to the source.
For older chimneys or ones with suspected flue problems, we may recommend a camera inspection of the interior. This shows cracks, blockages, or creosote buildup that are not visible from outside.
After inspection, you get a clear report of what needs fixing now, what can wait, and what it will cost. No guesswork.
Chimney and fireplace connections
Chimney problems and fireplace problems are often connected. A cracked flue liner affects how the fireplace drafts. A deteriorated chimney crown lets water down into the firebox. We look at the whole system, not just the visible damage.
If you are getting your chimney repaired and the fireplace needs attention too, we handle both in the same project. One crew, one quote, one timeline.
Chimney rebuilds
When the damage is too extensive for repair — crumbling brick on multiple sides, severely leaning, structural cracking — a rebuild is the right call. We tear down the chimney to sound masonry (usually at or just above the roofline), then rebuild with new brick, mortar, flashing, cap, and crown.
We match the new brick to the existing house as closely as possible. On heritage homes, that may mean sourcing salvaged brick or custom-manufacturing to match the original. The rebuilt chimney looks like it has always been there.
Maintenance and prevention
Have the chimney inspected once a year, ideally before heating season. Clean the flue if you burn wood — creosote buildup is a fire hazard. Check the cap and crown for cracks after winter. Keep an eye on the mortar joints — if you can poke mortar out with a screwdriver, it is time for repointing.
A chimney that gets regular attention will last 50 years or more between major repairs. One that gets ignored can need a full rebuild in 15.
Caps, crowns, and flue liners
The chimney cap sits on top of the flue and keeps rain, snow, birds, and debris out. Metal caps with mesh screens are the most durable option. The crown is the sloped concrete or mortar surface around the cap that sheds water away from the flue opening. Both need to be intact for the chimney to stay dry inside.
Flue liners protect the chimney walls from heat and combustion gases. Clay tile liners are standard in older homes. Stainless steel liners are used for relining when the original is cracked or missing. We install both types.
