A chimney liner, also known as a
chimney flue, is made out of clay, ceramic or metal pipe that runs down the
center of a chimney. The chimney liner’s purpose is to direct the flow of
combusted fuel products up and out of the home and to protect the chimney walls
and surrounding home structure from heat, fire and corrosion. Over time, or from
intense heat or cold, a chimney liner can become damaged or cracked.
There are a number of chimney liner repair options you can consider in the
invent it is determined that your chimney liner is damaged in some way. However
it is important to note that when repairing a chimney liner, a chimney flue
liner needs to be properly sized to maximize the efficiency for your particular
heating appliance, be it a wood stove, oil or gas burning furnace, etc. Check
with a chimney professional before deciding upon the right chimney liner repair
course of action.

Chimney Liner
Repair Options
Metal chimney liners, normally constructed out of either stainless steel or
aluminum, are probably the most commonly used in chimney liner repair. Metal
chimney liners, when properly installed, are extremely safe and rugged.
Stainless steel chimney liners can be used for gas, oil, or wood burning stoves
and furnaces. The less expensive aluminum chimney liner is sometimes used in
certain gas stove applications.

Cast-in place chimney liners are
commonly used to repair masonry chimney flues. Cast-in place chimney liners
involve inserting a cylindrical bladder into the damaged chimney flue and then
pouring a lightweight, castable, cement like product down the existing chimney
flue. The bladder is then removed to create a smooth and seamless chimney liner.
Two of the particularly good benefits with this type of chimney liner repair are
(1) that this type of chimney liner can be used with all types of fuels and (2)
it improves the structural integrity of the masonry fireplace.
So if an annual chimney inspection reveals a cracked or broken chimney liner,
don’t put off repairing the chimney liner, and check with a chimney professional
first to see what is the best chimney liner repair solution for your particular
situation.
