Working across London, Billing Chimneys provides professional and reliable chimney services, including the fitting of cowls and chimney caps. There is such a wide variety of caps and cowls available and we will ensure the most appropriate product is used for your specific needs.
Billing recommends that a cowl is fitted to a live flue in order to protect it and to improve its efficiency. Similarly, a cap is fitted primarily to keep an unused flue ventilated. Both caps and cowls will prevent debris build up which in a live flue can cause blockages and potentially chimney fires. One of the main culprits in this is birds’ nests and a cap or cowl will stop nesting in the first place. Another purpose is to prevent moisture getting into the flue from elements such as rain and snow. This moisture can cause damage to mortar and mould and mildew build up, especially in an unused flue. It is essential that caps and cowls are fitted and secured correctly.
The best kind of flue is an efficient one and cowls are great where there have been issues with draught. Some types are wind driven to improve the draw especially in windy conditions. These can be rotary or mechanical types. Complimentary to this they will also prevent wind-induced down draught, a condition that can send smoke back into a room. Where a flexible steel liner has been fitted a cowl is important.
