Every Chimney Needs A Chimney Liner!

If you have a fireplace and chimney system, you must have a chimney liner! Chimney flue liners are standard in chimneys today and are required by most fire codes. Without a properly functioning chimney liner, you’re setting yourself up for serious chimney damage and serious danger!

What Does A Chimney Liner Do?

A chimney liner’s main purpose is to protect the masonry structure from the heat and combustible byproducts that come with a fire. Without it, your masonry would quickly deteriorate, and nearby combustibles would be exposed to dangerous temperatures. Additionally, an unlined chimney will encourage creosote to build up more rapidly on the uneven surface of the masonry, and will allow dangerous gases and smoke to seep into your home. Creosote is an organic, tar-like substance that is deposited on the inside of your chimney as the smoke that carries it cools while moving up the chimney. Once enough of this builds up, a stray spark or the heat of the fire itself can ignite it and quickly lead to a house fire.

The Three Main Types Of Chimney Liners

Clay Tiles:
Clay tile liners are quite common among chimneys, as they are customizable and readily available. While they are not bad chimney liners, they do have some disadvantages:

  • Clay tiles are highly susceptible to damage as a result of changes in temperature. Over time, these tiles have a tendency to crack and fracture, negating their effectiveness and exposing the masonry underneath.

  • They can also allow combustible byproducts to get into cracks and seams, which can cause problems for a masonry chimney and pollute the air in your home.

In some cases, your clay tile liner may be able to be repaired and resurfaced using the innovative HeatShield® product. Learn more about this option here!

Metal chimney liners are used mostly in new builds or when the clay tile liner of an existing chimney is beyond repair. They are incredibly durable and versatile – in fact, stainless steel liners are safe for use with wood-burning, gas, and oil appliances. Aluminum, which is relatively inexpensive, is not safe for use with all fuel types, so if you’re considering a fuel switch at any time, an aluminum liner may not be your best choice. Here at London Chimney, we install and highly recommend Dalsin Stainless Steel Liners and M-Flex Stainless Steel Liners.

Cast-in-place liners are made of a concrete-like substance that is applied directly to the interior of your chimney. These liners are very effective as they are seamless and durable. On older chimneys, they can even increase the structural stability and integrity! Cast-in-place liners are some of the most popular liners available today.

How Do I Know Which Liner I Need?

A certified chimney sweep (like the ones at London Chimney Services) can inspect your chimney, determine the health of your existing chimney liner, discuss your use and plans, and weigh the pros and cons of each option available to you. If your liner is damaged, our techs have the knowledge and expertise to recommend a solution that will work best for your individual needs.
