    Default Crack in Chimney Flue

    I have a wood burning fire place that was inspected and cleaned last winter. Inspection came back that it had hairline cracks in the liner or flue that makes it inoperable because gases would leak into the house and it needs a new liner. My question is, aren't the clay liners in the chimney simply stacked on one another and thus there is a horizontal "hairline" crack between each of the liners already?

    The clay liners are basically there to "form" the chimney. Once they are cracked then you begin to have creosote buildup. Your best bet is to get a chimney flue liner. I would recommend contacting ChimneyLinerDepot.com. They helped me a lot when I put in my flue liner last fall. I found to that they had the lowest prices and best customer service.

    Howdy the liners are usually cemented together. The cracking is from too hot of fire, accelerants used to start the fire, wear, setteling of the chimney etc.
