A chimney liner, or flue, is the inner portion of a chimney that contains and channels the products of combustion.

For a chimney liner to work properly, it must be free from perforations, cracks, or damage of any kind. If it isn't intact it can allow the products of combustion, such as carbon monoxide, moisture, smoke, and creosote, to seep into the living spaces of the home, or the heat from the products of combustion to pose a fire risk to combustible materials near the flue such as framing, walls, ceilings, insulation, or floors.
