Chimneys and venting systems should be professionally inspected after changes to a chimney or vent system, a chimney fire or purchasing a home with a chimney.
The following should be checked during a chimney inspection:
- The chimney should be capped.
- Chimney should be protruding a minimum of 3 feet out of the roof and 2 feet higher than any part of the roof within 10 feet of itself.
- The crown or chase top should be watertight.
- The exterior chimney should be checked for cracks and deteoriation.
- The flashing and counter flashing should be examined.
- Chimney lining should be checked for creosote buildup, cracks and voids. If more than 1/4″ of creosote has accumulated, the chimney should be cleaned.
- The smoke chamber should be smooth and free of cracks, voids and creosote.
- The damper should open smoothly and close tightly.
- The firebox should be structurally sound and lined with firebrick. The mortar joints should be solid and the bricks should not be loose.
- The hearth extension should be checked for proper sizing.
- Combustible material should be the proper distance from the fireplace.
- Factory-built metal chimneys should be checked for disconnected chimney pipes.
- Wood framing surrounds most factory-built fireplaces and disconnected or rusted chimney pipes can catch fire.
Now, sit back and enjoy your fireplace on those cold evenings.
