There are three common reasons you may get the news that a chimney liner replacement is needed. Those reasons are deterioration, installation of a new appliance, and property transfer. Details are provided below.


The chimney liner originally built into your home was likely a clay tile liner. Most builders use clay tiles because they are both inexpensive and highly durable. Clay tile liners can last a decent amount of time, but this depends on various factors. For instance, how frequently do you use your masonry fireplace, and how well do you keep up with chimney maintenance?

No matter what type of chimney liner you have, it will eventually deteriorate. The cause of chimney liner damage might be age, moisture intrusion, or extreme temperatures, such as the intense heat caused by a chimney fire.

Your Current Liner Doesn’t Fit a New Appliance

Has a new fireplace or heating stove been installed inside your masonry fireplace? If so, the appliance must be fit to a flue of the correct size, per manufacturers’ instructions. If the chimney liner is too large or too small, the appliance will be inefficient. Other problems can also occur if the chimney liner is the wrong size, such as a buildup of condensation inside the liner. The potential issues partly depend on whether wood or gas fuels the appliance.

A New Liner is Needed for a Property Transfer

Your chimney liner must be able to pass a chimney inspection if you are making a property transfer. It is a requirement in the sale of a home.

Why is a Chimney Liner Necessary, Anyway?

A chimney liner must be intact for safety reasons. There are two primary functions of a chimney liner:

  1. Prevent combustible materials near the chimney from igniting, and
  2. Protect the occupants of the home from potentially deadly combustion fumes.

Clay tile liners make sense during construction, but the replacement of damaged clay tiles is expensive and impractical. Partial tear-down and a masonry rebuild of the chimney are necessary steps in replacing clay tiles. In the meantime, other tiles are at risk of deteriorating anytime.

Stainless steel chimney liners are durable and often come with a lifetime warranty. When chimney relining is necessary, chimney sweeps most frequently recommend a metal liner.
