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.

Caps, Covers, & Damper Repairs

Living in the south, mainly along the Gulf Coast, then you know there are lost of rain storms. Actually, we get more rain than anywhere else in the country, including Seattle. The ranking of the most amount of rainfall goes as follows: Mobile, Pensacola, and Seattle in 41st.

This region has such a big deal about rain when it comes to chimneys and fireplaces. As the Chimney Safety Institute of America explains, “water, not fire, causes most chimney damage.”

“Whether masonry or factory-built,” says the CSIA, “prolonged water exposure can result in cracks or gaps in chimneys where creosote can collect and increase the risk of fire or where noxious gases can escape into your home and expose your family to carbon monoxide.”

Fireplaces, Chimneys and Leaks

In basic terms the problem with fireplace and chimney leakage is that water combines with the creosote that remains from fires to form an acidic mixture. Over time that mixture can eat out the silica in the mortar joints.
Once the joints are no longer secure, moisture — remember all that Gulf Coast rain — can get into the house through the chimney. For example, if water comes in through the chimney and is released under the shingles it can lead to the need for a roof replacement.

Also, without proper sealing, heat from fires can travel into areas which should not be exposed to heat, dry out wood, and in some cases actually cause the wood to catch on fire.

In fact, according to a staff report by the US Consumer Product Safety Commission, there are about 22,000 fires a year which are associated with fireplaces, chimneys and chimney connectors. Such fires can cause substantial damage and in some cases may lead to fatalities.

Also, without caps it does happen that birds and animals get into fireplaces. Sometimes nests are built and in some cases animals unable to get out die inside chimneys and fireplaces. Noises and odors can result from such problems.

Caps, Covers and Dampers

You can protect your household with caps, covers and dampers. Caps with spark arresters are devices that go over the flue. They keep out both moisture and animals, plus they help prevent sparks from leaving the chimney. Covers are at the top of the chimney, go around the flue, and protect against moisture. Dampers are inside the chimney itself. They can help create a proper draft to achieve the best fire, plus when closed they prevent animals from getting into the house.
