• Loose or leaning pots—Usually a due to high winds, posing a fall hazard to people and the structure itself.


• Signs of damp—Often means the pot is no longer sealed correctly against rainwater.


• Avian obstructions—May obstruct the flue. Modern pots with built-in guards can avoid blockages effectively.
