Clay liner tiles are relatively inexpensive-about $10 for a typical 24â²-tall unit. But what you save on materials will most likely exceed the cost of installation labor. Clay flue liners are hard to retrofit in an existing chimney, especially if it isnât straight.lay liner tiles are relatively inexpensive-about $10 for a typical 24â²-tall unit.
