So your chimney sweep said you need to have your chimney relined… now what?
While chimney relining might seem like a daunting project with major construction, modern relining can be done easily and efficiently with a minimum amount of muss and fuss. If you are preparing to have your chimney relined, the following information can help you understand the relining process.
To understand chimney relining it is important to first understand what a chimney liner is and what function it serves.
The Chimney Safety Institute of America defines a chimney liner as “A clay, ceramic, or metal conduit installed inside of a chimney, intended to contain the combustion products, direct them to the outside atmosphere, and protect the chimney walls from heat and corrosion.”
How important is relining my chimney?
Although the tiles lining most chimneys are built to last, years of exposure to heat or corrosive byproducts of combustion can cause the chimney liner to erode or crack. When this happens, a serious safety problem is created; without the protective liner, surrounding building materials can be exposed to the heat from the fire. Likewise, gasses and smoke can sometimes escape out of the chimney and into your home. Because of this, it is important to have a damaged chimney relined as soon as possible.
Damage may not be the only reason a chimney needs to be relined; a change in the fireplace system may also require relining. Installing an insert or changing fuel sources can affect how small or large the flue needs to be. In order to maximize efficiency and prevent drafting or performance issues, your chimney may need to be relined to better fit the new fireplace.
Types of chimney liners
There are several choices when it comes to chimney liners. The type of chimney liner your home needs will depend on the type of fireplace you have as well as the level of damage to the existing chimney liner. The following are three of the most common types of chimney liners.
- Clay tile liners: Clay tile chimney liners are an inexpensive, popular choice and are standard in most masonry chimneys. Clay tile liners can deteriorate over time, especially at their masonry joints. While relining an entire chimney using clay tiles is virtually impossible because it would require removing portions of the chimney walls, it is possible to repair small sections using a HeatShield Cerfractory Resurfancing System.
- Cast in place liners: Cast in place chimney liners are created by pouring special cement directly into the flue. Special tools are then used to flatten and smooth the liner to the exact specifications of your chimney. Cast in place liners can also be used to help stabilize a damaged clay tile liner.
- Stainless steel liners: Stainless steel chimney liners are now considered to be the preferred choice for chimney relining. Stainless steel liners provide durability and safety that is unmatched by other types of chimney liners; they are designed to last longer and withstand heat better than most other liners.
