Virgo Chimney Sweep will be able to advise you on how often to sweep your chimney during the appointment.
How often to chimney sweep will depend on a number of factors including: type of fuel, appliance used, duration of use, moisture content of wood and type of chimney.
Use the correct fuel and if using wood it must be very dry or else it will cause tar build-up on the flue surface.
Sweeping your chimney will help in the prevention of chimney fires and reduce the risk of dangerous fume emissions from blocked heating appliances, flue-ways and chimneys.
Clean chimneys are safer and help your environment by assisting the complete combustion of the fuel.
Soot is an insulator and a clean stove will be more efficient heating your home.
