Chimney Liner Installation

Deteriorated Flue Tile

Deteriorated Flue Tile

According to the Chimney Safety Institute of America, chimney liners are defined 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.” Since the early part of the 20th century, building codes have recommended that chimney liners be installed. Modern building codes mandate chimney liners, although you will still find chimney liners absent in some older homes and buildings.

The Importance of Having a Functioning Liner

Chimney liners are important because they protect the house from the heat transfer. Hot gases can escape from the chimney into the walls of your home, catching the roof, wood framing or other structures on fire. Chimney fires are among the most devastating types of home fires and can quickly cause widespread destruction. A chimney liner’s function is to contain the hot gases and combustibles, keeping them safely away from the flammable structures in your home. Without a properly functioning liner, these gases can contain CO2, which can leak into the home without anyone knowing.

The Acidic Mixture

A chimney liner can also protect your masonry from the corrosive buildup that happens as a natural byproduct of combustion. Creosote, the tarlike substance that collects on the walls of your chimney from burning wood and other combustibles, is acidic and will eat away at the mortar joints from inside the chimney. If you have a ceramic or clay flue liner, the mortar holding the joints together are susceptible to this acidic mix as well. We can get a great view of this on the video scan done during a level 2 inspection.

Chimney liners also help to ensure that your chimney functions properly. A liner makes sure your chimney’s flue is correctly sized so that the appliances it serves operate efficiently. A chimney must have proper draft to make sure that dangerous gases exit the home and a properly-functioning liner helps with this. If you are having draft issues when starting or maintaining your fire, this is a potential reason as well.

An incorrectly-sized liner can cause an excessive buildup of creosote, damaging your chimney structure and possibly even causing the production of carbon monoxide. The liner of a chimney is hardly ever thought of as an important part of the functioning whole, but the truth is, it is overlooked at your peril.

Our expert chimney professionals can install a new liner in your chimney with a minimal amount of mess and disruption. For total replacement or new liners we recommend steel chimney liners. For ceramic or clay liners we will need to do a thorough video inspection to see the stage of potential damage to make a recommendation. We can do a tear-out-and-replace with a steel liner or possibly be able to repair with a method called HeatShield®.
