// ANATOMY
Click a part of the chimney
PART 01
Chimney cap
A chimney cap sits atop the chimney to prevent rain, debris, and animals from entering.
- Rust or corrosion can weaken the cap.
- Caps can become dislodged or damaged by strong winds.
- Nests or debris can accumulate if the cap is inadequate.
PART 02
Crown
The crown is a concrete or stone slab that seals the top of the chimney.
- Cracking due to weather exposure can lead to water leaks.
- Poor construction can cause premature degradation.
- Sealant wear may allow moisture to penetrate.
PART 03
Flashing
Flashing is metal sheeting that creates a waterproof seal between the chimney and roof.
- Improper installation can lead to water leaks.
- Corrosion or rust can cause flashing to fail.
- Sealant can deteriorate over time, allowing water entry.
PART 04
Brick and mortar
The brick and mortar form the structural walls of the chimney.
- Weathering can cause bricks to crack or spall.
- Mortar joints can erode, leading to structural instability.
- Moisture penetration can lead to further deterioration.
PART 05
Flue liner
The flue liner guides smoke and gases safely outside, protecting the chimney walls.
- Cracks or gaps can allow gases to escape.
- Build-up of creosote can be a fire hazard.
- Improper sizing can lead to inefficient venting.
PART 06
Smoke chamber
The smoke chamber funnels smoke from the firebox into the flue.
- Uneven walls can cause smoke to back up.
- Creosote can build up, increasing fire risk.
- Cracks or gaps can disrupt airflow.
PART 07
Damper
The damper seals the chimney when not in use to prevent drafts and heat loss.
- Rust can make the damper difficult to operate.
- Improper sealing can lead to heat loss.
- Debris can block the damper, preventing closure.
PART 08
Firebox
The firebox is where the fire is built, and it is lined with firebrick to contain the heat.
- Cracked firebricks can lead to heat damage.
- Mortar joints can degrade, compromising safety.
- Soot and debris can accumulate, requiring cleaning.
