Chimney Cleaning

As a guide all flues should be swept before and during the heating season, and ideally at the end of the heating season to prevent tar and soot deposits having a corrosive effect on the chimney and appliance during the dormant period.

Mechanical sweeping with brush and rods is the only method of cleaning recommended because materials other than soot can block the flue e.g. mortar, brickwork, birds’ nests. For this reason cleaning a flue using just chemical chimney cleaners or vacuum cleaning cannot be recommended as an alternative for correct chimney cleaning. (Some chemical cleaners can invalidate manufactures warranties).

Sweeping brushes should be made from suitable bristle and be of the same diameter or area as the flue being swept, and be fitted with a ball or free running wheel boss on the end to prevent scraping the flue walls, particularly at bends. Chimney manufacturers give instruction to which brush type to use on their systems. Use a qualified chimney sweep or member of NACS (National Association of Chimney Sweeps) who provide an inspection and sweeping certificate.
