What Does a Chimney Pot Do?

A chimney pot guides smoke up and away from your home, supporting effective draught and efficient flue operation. If it is damaged, it can lead to draught problems, damp, or even weather-related damage.

Common Clues Your Chimney Pot Needs Replacing

• Surface damage—Repeated freeze-thaw cycles can lead to cracks, which may worsen in colder months, letting water into the flue.


• Shifting chimney tops—Usually a caused by general wear, posing a safety concern to people and the structure itself.


• Water inside the firebox—Often means the pot is no longer providing protection against rainwater.


• Blocked flue from birds—Can block the flue. Contemporary replacements with built-in guards can deter nesting effectively.

Reasons to Choose Replacement

While minor repairs may work in the short term, a new chimney pot is typically more reliable. It ensures longer-term safety, and supports the integrity of the chimney stack as a whole.
