Chimney anatomy

01 · Chimney cap

The chimney cap sits on top of your chimney and prevents animals, debris, and rain from entering.

• Cap gets damaged or rusted
• Becomes loose or dislodged
• Clogs with debris

02 · Crown

The crown is a cement cover that sits on top of the chimney to protect it from the weather.

• Cracks develop over time
• Water seeps through
• Erosion due to weather exposure

03 · Flashing

Flashing is the metal barrier that seals the area where the chimney meets the roof.

• Leaks develop around the flashing
• Metal corrodes or rusts
• Flashing pulls away from the roof

04 · Brick and mortar

Brick and mortar form the main structure of your chimney, providing strength and stability.

• Bricks crack or crumble
• Mortar joints deteriorate
• Water damage causes spalling

05 · Flue liner

The flue liner protects the chimney walls from heat and corrosion, safely venting smoke and gases.

• Liner cracks or breaks
• Creosote buildup occurs
• Liner becomes misaligned

06 · Smoke chamber

The smoke chamber is the funnel-shaped area that directs smoke from the fireplace into the flue.

• Creosote buildup causes blockage
• Bricks or mortar deteriorate
• Smoke chamber misalignment

07 · Damper

The damper is a movable plate that controls airflow and keeps heat in when the fireplace is not in use.

• Damper becomes rusty or stuck
• Air leaks even when closed
• Handles or plates break

08 · Firebox

The firebox is where the fire burns, made of heat-resistant materials that withstand high temperatures.

• Bricks crack due to heat
• Mortar joints loosen
• Deterioration from excess moisture
