It is common to find that old chimneys are in a poor condition and can leak fumes, particularly if the flue is not lined. Over time hot smoke, tars and acids eat into the chimney walls and erode mortar joints causing staining to the exterior stone or brickwork, and leakage of dangerous fumes into the property. Large and uneven flues can also create poor up draught causing smoke to blow back into the room.
It was only in 1965 that Building Regulations required new chimneys to be built with suitable flue liners to protect the chimney structure and provide a smooth flue for efficient performance of the heating appliance.
Old chimneys should be checked by a professional competent person before being put back into use. This should identify what work or repairs are needed. It is prudent, and often essential, to fit a new liner to provide a smooth sealed flue way that ensures maximum safety and efficiency. Most stove and fire manufacturers require their appliances to be used with chimneys that have a suitable liner.
