The flue liner is an important part of any chimney system. It protects the chimney and the rest of your home from damaged caused by combustion materials. High heat, soot, and creosote can negatively impact your chimney. Additionally, a flue liner reduces the chances of a chimney fire. The best way to make sure your chimney liner isn’t damaged is to schedule regular chimney inspections. In fact, fire protection organizations recommend complete chimney inspections at least once a year. This is to ensure that all parts of the chimney system, including the liner, work properly.

What is a Flue Liner?

The flue liner, also referred to as the chimney liner, is a tube installed inside the chimney. Flue liners are made from clay tile or metals such as stainless steel. Heat, smoke, and other combusted byproducts are carried out of the chimney through the flue liner. Therefore, the liner prevents chemicals from harming your chimney walls.

Why is it Important?

The chimney liner is a very important part of your chimney and fireplace system. One reason is because it provides a barrier between the chimney walls and the harmful materials that fires produce. Direct contact from heat, soot, and other combustion materials can damage the chimney itself. Also, the chimney liner prevents dangerous gases like carbon monoxide from seeping into brick chimneys. The flue liner keeps your home and your family safe, which is why it is such a vital part of the chimney system.

How to Tell if Your Liner Needs Replaced

Like any other part of the home, chimney liners wear down over time. Lots of use, weather, and other factors can . Keep an eye out for these signs that your flue liner needs replaced:

  • Cracked or damaged clay tile liner
  • Condensation problems
  • You’ve converted your fireplace to another fireplace type or installed a fireplace insert
  • The metal flue liner is warped or deteriorating

If you notice these signs or any other damage to your chimney, contact your local chimney sweep. Your chimney sweep will thoroughly inspect your chimney and the flue liner, discussing any repairs or replacements that you need.
