What is a Chimney Liner?

The direct venting passage from your fireplace or appliance to the top of the chimney is provided by the chimney liner. Chimney liners are available in a variety of materials. In addition, when used in conjunction with the structure of the chimney made of brick or wood, they offer an extra layer of protection between the flue gases that are being vented and your home.

There are three primary categories of chimney liners, which are as follows:
Clay tile liners are baked clay liners, often measuring approximately two feet in length, that are placed on top of one another and cemented with heat-resistant mortar. These liners are sometimes referred to as “terra cotta” in some instances. These are often located in traditional chimneys made of brick.

Cast-in-place liners are liners that are injected into the chimney to create a tunnel from the bottom to the top. These liners are manufactured from materials that are comparable to concrete and are cast in a mold. In most cases, they are replacement liners that may be discovered in old chimneys in areas where the structure requires more strength.

Liners consisting of metal, such as aluminum or stainless steel, are known as metal liners. Their major usage is to replace clay tile liners that are broken or missing, and this use makes them the most common alternative for repair or upgrade work done today.

Liner faults, regardless of how large the gap or crack is, can start a process that will progressively destroy the integrity of the chimney structure and can pose a hazard to the safety of your family by allowing carbon monoxide to flow out of the chimney. Creosote and soot, both of which are flammable, have the potential to build up outside the chimney flue liner if they are allowed to escape through these openings and accumulate there. This poses a substantial risk of fire.

In the event that the creosote were to catch fire in this area, serious damage could be caused because the fire would no longer be contained within the flue but rather spread outside the flue, directly adjacent to the primary building structure. If this were to happen, the situation would be extremely dangerous.

How Much Does It Typically Cost to Have a Chimney Liner Installed?
The cost of installing a stainless steel liner in a gas furnace normally falls anywhere between $1,800 and $2,500, while the cost of installing a liner in a fireplace can vary anywhere from $2,700 to $4,000. The liner dimensions (length and diameter), the number of appliances that need to be connected, as well as the types of connectors that are required, are the primary factors that determine the cost. The degree of complexity is also a factor.

Performing maintenance on your chimney liner
It is essential to perform regular maintenance on the chimney lining system, including inspections and cleanings. This is done to ensure the homeowner’s safety and is frequently required in order to fulfill the criteria of the guarantee for stainless steel liners. Depending on how often the appliance is used, it may be necessary to do maintenance on a solid fuel-burning device more frequently. It is necessary to do a thorough inspection and cleaning of the whole system, beginning at the connection at the appliance and working one’s way up to the liner.
