There are various reasons why you would want to change or get rid of an existing chimney pot. These reasons can be as follows:
1) To prevent water going into the flue and potentially triggering moist– A lot of chimney pots have open tops so there is direct access for water. Over an amount of time this can trigger damp to the chimney stack and surrounding locations. There is likewise the possibility of birds falling down the chimney stack. They perch themselves on the edge of the chimney pot and can the fumes can knock them unconscious so they drop the flu.
2) To prevent damage to the chimney stack– Traditional chimney pots are generally rather high and very heavy. If the mortar around the pots comes loose they can start to sway causing damage to the stack. If one of these pots falls off it can trigger remarkable damage to the chimney stack/roof/parked vehicles or even a passerby.
3) The chimney is no longer in use– If the chimney is no longer in use then there is no requirement for such a huge chimney pot to be present.
If you want your chimney pots removing for among the above reasons I recommend you change them with a 6 inch gas cowl. These are very light, simple to fit and permit ventilation in unused chimney influenza’s. They also offer adequate upward motion in the air to get rid of harmful gas and smoke from your home.
