Signs You Need a New Chimney Liner

Your chimney might not be something you think about every day, but it plays an essential role in keeping your home safe and warm. At the heart of your chimney system is the liner—a significant component that protects your home from heat, combustion materials, and toxic gases. But how do you know when it’s time for a new chimney liner? Read on to discover the key signs homeowners should look out for.

What is a Chimney Liner, and Why Does It Matter?

Before we jump into the signs, let’s quickly understand its purpose. A chimney liner is a protective barrier, traditionally made from metal, clay tiles, or a specialized resin. It keeps heat, smoke, and harmful gases contained within the chimney and away from your home’s structure. Without it, your home could face increased risks of fire damage, carbon monoxide leaks, and expensive repairs.
