What Does a Chimney Pot Do?

A chimney top helps direct smoke up and away from your home, ensuring effective draught and safe ventilation. If it becomes ineffective, it can lead to poor indoor air quality, damp, or even structural damage.

Common Clues Your Chimney Pot Needs Replacing

• Fractures—Long-term weather exposure can result in cracks, which may get worse in colder months, letting water into the flue.


• Loose or leaning pots—Usually a sign of damaged mortar, posing a fall hazard to people and the structure itself.


• Signs of damp—Often means the pot is no longer aligned properly against rainwater.


• Blocked flue from birds—May obstruct the flue. Contemporary replacements with built-in guards can keep birds out effectively.

Reasons to Choose Replacement

While short-term fixes may work in the short term, a replacement chimney pot is generally more reliable. It ensures greater draught stability, and protects the chimney stack as a whole.

How to Select the Best Chimney Pot

Choosing the here right pot means looking at more than just its design.

• Build quality—Clay remains a solid choice due to its thermal resistance.


• Diameter—Needs to fit the flue size. An incorrect size may affect draught.


• Visual match—Pots are available in traditional or contemporary styles to match the existing roofscape.
