Why is a Chimney Liner and Chimney Lining System Important?

Believe it or not chimney liners actually play an important part in keeping your home safe.

So what is a chimney liner? First let’s define what a chimney liner actually is.

Chimney liners in your masonry chimney are built with terra-cotta clay tiles that are stacked on top of each other and mortared together. A chimney liner is a gas-tight and heat-resistant insulator that protects your home’s masonry chimney.

Another type of liner is a stainless steel liner. These are often found attached to a furnace, wood stove or fireplace. Your heating source will vent up through the stainless steel liner. It is housed inside of your existing brick structure.

New liners gives us efficient chimneys that are safe to use and solve most issues regarding drafting. If a liner is absent or has cracks, there could be heat transfer and gas leaks to combustible materials which can cause a fire seepage through your home’s brick and mortar.


What are the functions of a chimney liner?

  • Prevents damage to your masonry fireplace and chimney.- Bricks, believe it or not, are actually very porous. When you have active flames in your fireplace, the combustion creates corrosive by products. Essentially the mortar joints are eaten away by the corrosion which allows for rapid heat transfer. If this goes unnoticed or not taken care of, eventually dangerous problems like carbon monoxide can leak into your home.
  • Protects you and your home from accidental chimney fires.
    – Another reason why a liner is important, they prevent the risk of accidental fires from breaking out in your home. Chimney liners limit the heat transfers from coming into too much contact with the supporting structures or combustible framing that are near your chimney. These prevent fire hazards from breaking out.

Warning Signs Your Chimney Might Need Repairs

Usually by the time the average homeowner notices a problem with their chimney, it has probably needed some repairs for quite some time. To avoid any future repairs (big or small) be sure to be on the lookout for these signs.  

  • Damaged Lining

Unfortunately, there are usually no obvious signs that a chimney liner is damaged. In some rare cases, you may notice broken masonry in your fireplace and the debris could be bits of a deteriorating flue liner that have fallen into the firebox. Because it is usually not obvious that a liner needs to be repaired, it’s important to have a reputable chimney sweep inspect your chimney’s flue annually. To avoid harmful hazards such as creosote on your liner and home, schedule a chimney sweep to remove the soot and creosote before it turns into Stage 3 and damages your liner.

  • Water Damage

Water Damage


From something as serious as crumbling masonry to something seemingly harmless like droplets of water, both are usually reasons enough to call over a professional chimney sweep to have a look at your chimney. A certified chimney sweep will also be able to inspect your flashing, the chimney cap as well as the crown which tend to be the common causes for a leaking chimney. Other signs of a leaky chimney include:

  Water stains on masonry, walls and/or ceilings.

  A musty odor coming from within the chimney,
   clogged cleaned-out area and/or wet ashes

  To avoid some water damage have your
    chimney waterproofed professionally.

  • Wear and Tear

Damaged firebox


The firebox/fireplace is usually the part of your home’s chimney system that receives the least amount of attention even though it withstands the most heat and abuse. If built with the incorrect materials or if affected by water penetration the masonry can be damaged which can be disastrous. In order to avoid disastrous damages to your firebox, assessing the firebox as part of your monthly home maintenance is the best way to stay on top of it. You can do so by removing ashes and by looking for cracks in your chimney’s masonry.
