Now look inside,
see the problems?
we look at the interior of the same
chimney we can find a number of
imperfect conditions. Pieces are
missing from the original clay liner
and there are cracks in the clay
liner. (Old chimneys might not even
have a liner.) Mortar and bricks
are loose and falling. And there
is excessive buildup of combustable
creosote on the flue walls.
These conditions are the result
of a number of possible causes,
including: flue fires, an
improperly vented or misused stove,
poor construction, excessive moisture,
With continued use of this chimney,
any of these conditions could lead
to loss of property or life.
