Common Repairs to Chimney Liners

Common Chimney Flue Liner Repairs

 Although many people have chimneys in their homes, most do not know much about the parts that comprise them. One of the most important parts of a functioning chimney is the flue liner. This is a layer, usually made of clay, metal, or ceramic tile that covers the inside of the chimney. Its function is to protect the inner wall of the chimney as well as to contain combustible materials while sending them out of the home. Keeping the chimney flue liner in good working condition is essential to having a safe chimney.

Prior to the 1940’s, it was not mandatory for homes to have liners in their chimneys. This is why tragic house fires were so common in the middle part of the Twentieth Century. Someone who is living in a home that was built before the 1940’s should have their chimney inspected and make sure that it has a liner to begin with. If it does not, one must be installed before the fireplace can be safely used.

In most cases, the flue liner needs to be replaced or repaired because of normal wear and tear from years of use. In this case, the liner will simply start to wear away or, in the case of an older tile liner, it will begin to crack. This is dangerous because the liner will not be able to contain hazardous gasses the way that it is supposed to. These materials may be allowed to ignite, causing a devastating chimney fire.

Combustible gasses themselves will eventually take their toll on the liner, which is another thing a professional inspection should catch. When this happens, the connection between the liner and the wall of the chimney weakens, causing it to become loose. Although the cause is different, this creates more or less the same effect as an eroding liner. It can be extremely unsafe and a chimney in this condition should not be used under any circumstances.

When the time comes to repair or replace the chimney liner, people with metal or tile liners in their homes find that it is best to make a complete change. Today, it is often recommended that these liners be replaced with ones that are made of clay. The reason is that clay is extremely durable and can withstand not only exposure to combustible materials but also to extremely high temperatures. If someone installs a new clay liner in their chimney, they can expect that it will remain in good working condition for about fifty years.

While making the switch, it is important to avoid fire hazards by completely removing all pieces of the old liner. It is also necessary to measure the chimney precisely and account for any irregularities, such as a crooked chimney. In order to function safely, the liner must fit the chimney exactly. These repairs are extremely complicated and it is not recommended that they are done as a do it yourself project. A profession should always be employed to do this precise work and make sure that it is safe before use.

Although many people are not aware of the condition of their chimney liner, it is a very important safety issue. An annual chimney inspection will give insight into whether or not any repairs or a complete replacement is necessary. These days, many homeowners opt for a clay liner because it is durable and will most likely last for the duration of their time in the home.
