Chimney cleanout doors & openings: this article describes chimney cleanout access doors or ports. We explain that in addition to using the chimney cleanout as a service port to remove debris that has fallen to the bottom of a masonry chimney, the cleanout door and the type of debris found inside can tell us something about the condition of the chimney flue even though we cannot see most of it. Also see How to Inspect a Barometric Damper for another spot where it may be possible to inspect for clues about the condition of a chimney and its safety.
These articles on chimneys and chimney safety provide detailed suggestions describing how to perform a thorough visual inspection of chimneys for safety and other defects. Chimney inspection methods and chimney repair methods are also discussed.

All chimneys must have a cleanout at least 12" below the lowest appliance inlet opening. A fireplace is considered as access for cleaning. Cleanouts must have metal or pre cast concrete doors that can be secured tightly
In the photo at above left, the chimney cleanout is easy to find and the door is in place and closed; look inside for clues of flue damage and also for the presence of a flue liner if this is a single-brick wythe flue.
In the photo at above right the home made cleanout door was a metal scrap propped against the chimney. It has fallen open, and we see some masonry debris that has fallen down the flue.
