3. My chimney is backing up – What to do?
If your chimney is drafting poorly, you notice a smoke backflow or suspicious noises - better safe than sorry: extinguish the fire immediately and have a chimney sweep come to perform a camera inspection.
The problem may be due to obstructions such as bird or insect nests mentioned above, as well as the chimney itself. For example, the company Gentleman Ramoneur can tell the story of a case where, after work on an upstairs room in a house, a brick had come loose from the inner side of the duct. It blocked the evacuation of the smoke and it had perforated the duct, which allowed soot and smoke to pass into the adjoining wall...
To ascertain the damage, Gentleman Ramoneur had to use a camera attached to the end of the flexible rods of its rotary chimney sweeping tool that transmits the image directly onto a monitor. Afterwards, this video could be used to create the insurance file against the contractor at fault.
