Chimney Repair and Rebuilding in Montréal

Common chimney problems we repair

Montréal chimneys are exposed to rain, snow, ice, and temperature swings, so they often deteriorate faster than the rest of the brickwork. On site, we most often see

• Cracked, leaning, or loose brick chimneys.

• Spalling bricks (faces popping off), missing mortar, and open joints.

• Cracked or crumbling chimney crowns and concrete caps.

• Water leaks around the chimney, damaged flashing, and stained interior walls.

• Chimneys no longer up to code height or too close to rooflines or windows.

If you notice loose bricks, pieces of mortar on the roof, or water stains near your chimney, it’s time to have it checked.

Our Chimney Repair and Rebuild Services

We handle everything from minor chimney repairs to complete rebuilds from the roofline up or from the ground up, depending on the condition of the structure. Our goal is to restore both safety and appearance while matching your existing brick or stone as closely as possible.

• Brick chimney repair: replacing loose, cracked, or spalled bricks and repointing deteriorated mortar joints.

• Chimney rebuilding: partial or full rebuilds when the structure is unstable, leaning, or severely deteriorated.

• Crown and cap replacement: new concrete crowns with proper slope and drip edge to shed water away from the chimney.

• Chimney flashing repairs: fixing or replacing metal flashing where the chimney meets the roof to stop leaks.

• Stone chimney repairs: matching existing stone, rebuilding damaged sections, and repointing joints.

• Chimney removal: safe removal of unused or unsafe chimneys when repair is no longer practical.

We always prioritize repairs where possible and only recommend a full rebuild when it’s the safest and most cost‑effective long‑term option.

Our Chimney Repair Process

We keep the process clear so you always know what is happening on your roof.
