While your chimney liner may be one of the most important parts of the chimney system, it is often one of the most overlooked — one reason being because you can’t exactly look at it! The liner is the part that covers the inside of the masonry from top to bottom, working as a protective barrier.

The Liner’s Job

The chimney liner actually has multiple jobs, and they’re all very important.

  • First, the liner protects the masonry from the corrosive chemical byproducts of the fire. If allowed to sit on the masonry, soot and creosote can damage it from the inside out.
  • The liner also creates a properly-sized vent for your fireplace. Without the liner, the chimney flue may be too large, making the chimney inefficient. Or it may be rough, disrupting airflow and promoting buildups.
  • Finally, the liner serves as a barrier, protecting the home from harmful chemicals that can pass through the masonry and keeping heat from transferring to building materials in the house.

Types of Liners

Older masonry chimneys generally have clay tile liners. These work well and are quite affordable, however they do not last as long as other options, and they are not appropriate for gas or oil heat. If you have a clay tile liner, you should only be burning properly-seasoned wood.

Anderson’s Chimney and Masonry Services sees a lot of relining due to broken and worn-out clay tile. In order to reline your chimney, we may recommend one of two options.

  • Stainless Steel Liner – Possibly the most expensive option, stainless steel liners are the best and longest-lasting liner for your chimney. They are also safe for all fuel types, and can last 80 years. Your stainless steel liner can go directly over damaged clay tiles, will be insulated to keep the heat in, and keep the chimney working efficiently.
  • HeatShield Liner – HeatShield relining and repair systems offer another option that is easy to install, repairs any lining problem, and is long lasting. It’s also affordable and safe for all fuel types. At Anderson’s, we trust HeatShield because the cerfractory system has been tested in the worst conditions. Our staff have undergone extensive training in order to be HeatShield certified, and we can reline your chimney now.

If you frequently find pieces of broken clay tiles in your fireplace, your masonry is dangerously hot to the touch, or you think your chimney isn’t lined at all, you need to call a professional today. Call Anderson’s at 717-975-3526.
