A chimney liner is an important part of your fireplace system. According to the Chimney Safety Institute of America, a chimney liner acts as a protective barrier to your masonry chimney. It protects against the flue gases that a fire produces. These gases can cause serious damage to the mortar joints inside your chimney. Also, causing enough breakdown that they can leak back into your home. And if that’s not enough of an issue, this can also shorten the workable life of your chimney.

Another reason that chimney liners are important? They make your chimney run more efficiently. A chimney needs the correct sized flue in order for modern wood stoves and fireplaces to run correctly. If your chimney flue is not the correct size, a properly sized chimney liner can solve the problem. It will allow for your chimney to increase efficiency. Incorrectly sized flues can cause not only creosote buildup, but also increased carbon monoxide production.

Although most new homes have a chimney liner already installed, if you own a home that was built earlier than the 1940’s, it is very possible that your chimney does not have a liner. The best way to know if you need a chimney liner? Have a professional, like the CSIA certified professionals at the Chimney Doctors of Colorado, come in and check it out! If your chimney does not have a liner, these professionals will be able to advise you on the best possible liner for your home. In addition, if your chimney does have a liner, they will be able to tell you the condition it’s in, and if it needs repairing.

According to OldHouseJournal.com, one reason that chimney liners need to be replaced is because they weren’t a part of your chimney in the first place. Another reason is that your chimney liner may have been damaged by precipitation combined with combustion gases. This causes eroding in your existing liner. Also, just like everything else in your home, age will play a role in the breakdown of your chimney liner. Once your liner has cracks or holes in it, it decreases efficiency and effectiveness.
