    Why Unlined Chimneys are Unsafe

    Do you live in an older home – one that was built 60 years ago or more?  If so, it is important to make sure that your chimney is lined.  Especially if you haven’t had it swept in the past, you may be unaware of both the state of the chimney and whether or not it is lined.  Although building codes have required chimney liners since the early part of the century, regulation of these codes was often subpar.  This makes homes constructed prior to the 1950s more likely than newer properties to be improperly lined.  

    A liner serves three important functions:C

    1. Liners protect the home from high heat transfer to other combustibles nearby.
    2. Liners safeguard the masonry from the effects of corrosive combustible byproducts.  These byproducts increase the deterioration the brickwork making its lifespan much shorter.  They also reduce the brickworks ability to block carbon monoxide and other gases from entering the living space.
    3. Liners offer better combustion leading to a more efficient fire and less creosote buildup.  Creosote is one of the leading causes of in-home chimney fires.

    Chimney liners come in three main materials: clay, cast-in place, and metal.  Hire a certified sweep to inspect the area to determine if your chimney has a proper liner.  If you do have a liner, you will also want them to make sure it is not damaged or cracked. A damaged or cracked liner can allow excessive heat transfer and creosote buildup.
