The Average Lifespan of a Chimney Liner

The average lifespan of a chimney liner. To keep your chimney in great shape for many years, you’ll need a high-quality, durable chimney liner. The chimney liner, or flue liner, is installed inside of the chimney, and it helps protect your chimney walls. Whether you already have a liner or are looking for one now, you’ll want to know how long it will last. 

What’s the average lifespan?

Read on to find out.

The Importance of a Chimney Liner

Liners are made of ceramic, metal, or clay, and they are required in most modern buildings. Each year, the liner must be cleaned with a professional chimney sweep, to remove any soot or creosote buildup. 

The primary purpose of the liner is to protect your home and chimney. It actually protects your home from heat transfer to combustible materials. They also protect your chimney. They offer a layer of protection for the chimney masonry, helping preserve it from damaging corrosive byproducts. Another key quality of chimney liners is that they create the perfect flue size for optimum efficiency. Properly sized liners prevent creosote buildup and carbon monoxide because they ensure the correct draft. 

The lifespan of a Chimney Liner

As you can tell, liners are very important for your chimney and home. But as a homeowner, you definitely need to know how long they last. The average lifespan of a chimney liner is 15-20 years. Typically, after two decades you should replace the entire liner. 

While the average lifespan is 15-20 years, there are many factors that will determine the lifespan of your chimney liner. Some factors that impact chimney liner lifespan include:

  • Material: Stainless steel flue liners can last much longer than 20 years compared to cast-in-place or clay tile. 
  • Quality: Very cheap liners will need frequent repairs and could require replacement in only 5 years. 
  • Maintenance: Adhering to proper chimney maintenance helps your liner (and entire chimney) last longer.
