Cracking
is a major problem especially in older chimneys. Many factors play a role
in the deterioration of brick and mortar. Not all bricks are created equal
!
Weak,
cracked or missing mortar will cause creasote to bleed through the chimney.
This makes for a smelly and dangerous situation. If a chimney fire happens,
the fire will follow the fuel (creasote} through the chimney wall and start
a fire in the living space.
