What a chimney pot actually does
The pot extends the flue above the stack, improving draw for an active fireplace and helping keep wind-driven rain out of the chimney opening — it's a functional part of the chimney, not just decoration.
Choosing the right pot
Pot style, height and clay type should match both the property's period and the flue's actual requirements, particularly on listed or conservation-area properties common across parts of Bristol.
Installation and flaunching
A new pot is bedded into fresh flaunching — the mortar collar at the top of the stack — which needs to be shaped correctly to shed water away from the pot rather than pooling around its base.
