5 Common Chimney Safety Issues Found In Older Homes

Fireplaces are a typical feature in most older homes. Mortar and brickwork deterioration can lead to these buildings becoming more vulnerable to overheating, carbon monoxide leaks, and outdated building codes. Here are some of the most common chimney safety issues you’ll see in older homes:

Chimney Obstruction

Chimney blockage may not have immediate consequences, but it can lead to long-term problems. A chimney obstruction reduces airflow. Because gases and vapors are unable to depart the chimney, a buildup of carbon monoxide occurs.

Inadequate Venting

The most typical reason for chimney fires is a lack of ventilation in a fireplace. If the exhaust vents back up or reverse their direction, they might cause the structural supports of the chimney liner to fail, resulting in serious damage to your home’s indoor air quality.


Creosote is a black, waxy residue that builds up on creosote-treated wood near fireplaces and masonry chimneys. Creosote can lead to fires in the chimney, providing a source of ignition for combustibles elsewhere in the home, as well as toxic gases.

Masonry Chimney

Masonry chimneys are prone to deterioration over time. Damaged masonry chimneys may be unsightly as well as cause structural damage to your house in the event of a fire. Excessive wear and tear can also result in fractures, which can lead to masonry wall and foundation failure.

Cracks in the Flue

During building, cracks in the chimney flue are expected, although if they result in a full failure, they may be dangerous. Many chimney failures are caused by lath or masonry reinforcements that aren’t adequate inside the chimney.

It is critical to use safety procedures, such as inspecting the chimney for obstruction, flue failure, and chimney structure maintenance, when old homes are remodeled.
