Chimneys need to be swept in order to allow free passage of dangerous combustion gasses. Regular cleaning of the chimney will remove soot and creosote, helping prevent dangerous chimney fires. Cleaning the chimneys regularly will also ensure that your wood-burner continues to perform well. Chimney sweeping will remove bird nests, cobwebs and other blockages.
Chimney Sweeping frequencies will depend on a number of factors, such as, the type of fuel you are burning, the duration of use, the moisture content of the fuel and the type of chimney you have. The guide for chimney sweeping frequencies when burning wood is quarterly when in use, and when burning coal, it is recommended that the chimney is swept annually.
