Chase
The outside structure of the chimney which can be wood, Masonite, stucco, brick, stone, block and is hollow between the flue and the outer wall.
Flue
The lined opening from the fireplace to 4 or more inches above the crown wash. A Masonry system is lined with flue tiles while manufactured or z/c systems have double or triple wall metal flues.
Crown Wash
The layer of cement at the top of masonry chimneys. Manufactured system chimneys have a metal top.
Crown
The upper rows of bricks on a masonry chimney.
Flue Cap
A metal cap with mesh to act as an approved spark arrestor as specified by building code.
Damper
The structure opens and closes to allow the smoke to go up the flue to the outside.
Firebox
Holds the grate and is where the wood is put to burn.
Common Chimney Problems
Rusted/broken damper
Normally caused by water entering the flue or rough treatment
Animals/birds in the firebox
No flue cap at the top or a cap with no mesh
Damaged back wall
Moisture enters the flue and seeps behind the back wall. Over time, heat and cooling from fires expands and contracts the back wall causing the damage.
ALL of the above common chimney problems can be solved with a good flue cap.
Damaged Crown Wash
Age, weather and inadequate thickness are the normal reasons for the Crown Wash to fail.
Cracked Flue Tiles
This type of damage is often caused by a chimney fire(s).
