Decorative Chimney Pots also Extend Chimney Height

As we defined at CHIMNEY CAP & CROWN DEFINITIONS, the term "chimney pot" is used to describe a decorative rain cap assembly on the top of a chimney, covering its flue and in some cases covering both the flue itself and the entire chimney top, including the chimney flue and chimney cap/crown. Typically the chimney pot also adds height to the top of the chimney flue and it may improve chimney performance as well.

Our photo (above left) of a Boston Massachusetts chimney top and Carson Dunlop Associates' sketch at above right illustrates a typical chimney pot design, a decorative treatment used at the top of (usually masonry) chimneys.

A chimney pot is often cast of concrete or constructed of fired clay in a decorative design as we illustrate further below.

What is not clear in the Carson Dunlop sketch but what you will see in our photographs below, is that most decorative chimney tops, caps, or crown assemblies cover the flue and include rain cap protection as part of their design.

Those "eye' shaped openings visible in these decorative chimney crown assemblies are the actual vents, while a domed top offers rain protection for the chimney flue. The decorative chimney top design used here overhangs the entire chimney side, providing good drip-edge protection for the chimney top and sides. - Photos ©DJF.

The chimney pots at above left, located on a Boston MA building, illustrate a crowded, possibly multi-flue chimney serving multiple apartments in a building. These chimney tops and pots are touching, crowded, some not even vertical, raising a several worries:

Either of these may in turn lead to unsafe chimney flues.
