Maçonnerie J. Légaré is a residential masonry contractor based in Cantley, serving the Outaouais region and homeowners near Ottawa. Chimneys are one of the parts of a house we are called to most often, because a chimney stands exposed on every side and its masonry takes the full weight of freeze and thaw cycles year after year.
Our work on a chimney is masonry work. That means brick, stone and mortar: replacing units that have cracked or crumbled, repointing joints that have worn away, repairing cracks that run through the stack, and stabilizing masonry that has started to shift. Nothing more, nothing outside the trade.
Chimney repair Ottawa and Outaouais homeowners request usually starts with something small and visible — a joint you can scrape with a fingernail, a piece of brick found on the ground. We come and look at the chimney first, tell you plainly what has deteriorated, and only then put a quote together. In Cantley and across the Outaouais, that visit is how every job begins.
Most chimney masonry problems start in the mortar joints, not in the bricks. A chimney stands above the roof with no shelter on any side, so rain is driven straight into the joints and every freeze and thaw cycle loosens them a little more. Once the mortar has receded behind the face of the brick, water sits in the joint, soaks into the units and starts to break them apart.
Chimney tuckpointing, which most people also call repointing, puts sound joints back without taking the chimney down. We rake out the deteriorated mortar to a solid depth, clean the joints, then pack them with fresh mortar in layers and tool them so they shed water. The mortar is chosen to suit the existing brick or stone: a mix that is harder than the units can make the bricks crack instead of the joints.
Repointing alone is enough when the bricks are still sound. When units have spalled or cracked through, we replace them first and repoint around them. We also repair or rebuild the crown at the top of the chimney, because a cracked crown sends water straight down into the masonry below.
For brick walls rather than chimneys, see our brick repointing and masonry repair page.

Chimney masonry gives warning before it fails. These are the signs worth calling us about, and they are all things you can see from the ground or from a window.
Cracked, chipped or crumbling bricks on the chimney stack
Mortar joints that are hollow, powdery or missing altogether
Loose or shifted stone units near the top of the chimney
Visible cracks running through the chimney masonry
Pieces of brick, stone or mortar found on the roof or on the ground
Any one of these is a reason to have the chimney assessed. Masonry that is losing its joints keeps losing them, and a small repointing job left alone for a few seasons becomes a rebuild. An assessment costs you a phone call.
