When it comes to the condition of your chimney, there may be hidden hazards. The chimney liner, which runs the length of the flue, serves an important role in protecting your home from the heat and gas produced by the fireplace. However, it cannot be examined without special equipment. Whether your liner is dirty, damaged, or does not meet the needs of your current fuel source, you might need to get your chimney relined.
What is chimney relining? 
The chimney liner is “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.” However, age, overuse, or lack of maintenance can all cause damage to the chimney liner.
Because the chimney liner plays such an important role in protecting your home from heat transfer, a cracked or damaged chimney liner can create a significant safety problem. Likewise, installing a new fireplace insert or switching fuel sources may also require your chimney to be relined. This can prevent drafting issues as well as ensure there will not be damage from byproducts of combustion.
Three types of chimney liners
There are three types of chimney liners that are used in homes today. The type of chimney liner your home needs will depend on the damage to the existing liner as well as the fuel source of the fireplace.
- Clay tile liners. Clay tile liners are the standard when most chimneys are built. While built to withstand heat, the masonry joints can deteriorate over time. Clay tile liners are nearly impossible to replace as they are built using sections of tiles which cannot be easily taken out or replaced. Heatshield can also be used to repair a clay tile liner without relining the entire flue.
- Cast in place liners. Cast in place liners are created by applying a cement product directly to the walls of the flue using a former. This creates a seamless, smoke tight finish that can also help stabilize a damaged flue.
- Stainless steel liners. Stainless steel liners are a more expensive relining option but provide the best durability and heat resistance. Many stainless steel liners include a lifetime warranty when they are professionally installed.
Does my chimney need to be relined?
The best way to determine if your chimney needs to be relined is through a chimney inspection. During a Level II chimney inspection, a certified chimney sweep will use technology such as closed circuit cameras in order to evaluate the entire length of the chimney liner. This allows creosote buildup, damage to the liner, or cracking joints to be discovered.
