How to clean a chimney

Cleaning a flue liner is a moderately challenging task and shouldn’t be performed by someone who doesn’t know what they are doing.

Flues are tubes within your chimney which carry smoke from your fire or furnace out of your building.  Chimneys are typically lined, either with ceramic flue tiles or metal.
