Like all chimney components, chimney liners need to be replaced from time to time. Chimney liner replacement, however, is a crucial issue when there is deterioration. If the flue liner is not fully intact, your home and family are endangered when the fireplace is used. There are two life-threatening hazards caused by damaged chimney liners that cannot be ignored, as follows:

The Threat of a House Fire

When a chimney liner has even a tiny crack, combustible parts of the home are exposed to extreme heat. A process called pyrolysis occurs over time. Pyrolysis changes the combustible materials so that they ignite at much lower temperatures. Without any warning, a home can ignite and the fire can spread rapidly.

The Threat of Carbon Monoxide Exposure

A little crack is all it takes for carbon monoxide to leak into the living area of a home. Carbon monoxide is known as the Silent Killer, and it’s for good reason. It is odorless, tasteless, invisible, and symptomless. Therefore, victims of carbon monoxide exposure are unaware of the danger. According to the Centers for Disease Control and Prevention, at least 430 people die annually from carbon monoxide poisoning.

A Bad Fit

If you replace a fireplace or heating stove with a new appliance, a chimney liner replacement is likely needed. The manufacturer’s instructions will specify the correct size of the chimney flue that should be fitted to the appliance. If the chimney flue liner is too small or too large, the appliance will work inefficiently. It could cause condensation to build up inside the liner, as well.
