Why is a chimney sweep so important?   

1. The gradual accumulation of soot can seriously affect the way your chimney performs. Thick layers of soot of course can physically restrict the flue so there is no longer enough free area to vent the appliance properly.
    
2. In order to maintain the peak operating conditions which means free from debris, nest, birds, animals and creosote.
    
3. If the chimney is swept on a regular basis at the end of each season the build-up can be prevented. If however you are at the point where the build-up has turned into a graze, a special type of cleaning will be necessary above and beyond a regular sweep.
