4 Common Issues in Old Chimneys champion chimneys

If you have a chimney that was built a long time ago, be sure to look out for these common problems

If you own an older house, you will have different responsibilities than those who own newer homes. Newer homes are usually built following modern building codes and using materials that conform to today’s standards. However, with all the charming characteristics of old homes, some unique problems need to be addressed. Older chimneys were constructed with fewer regulations and requirements than the chimneys of today. If you have a chimney that was built a long time ago, be sure to look out for these common problems. Keep reading to learn more.

Masonry Cracks

No matter how sturdy your masonry may appear, constant exposure to weather, heat, and moisture damages brick structures. The worst problem they encounter, especially in harsh winters, is moisture entering the flue and seeping between bricks. Even without freezing temperatures, water can cause cracking in bricks. However, it worsens when the water freezes and expands, forcing gaps in the bricks and masonry. It is essential to have regular maintenance on your old chimney to check for, and repair cracked masonry. You should also install a chimney cap to keep away moisture.

No Chimney Liner

It is incredibly common for older chimneys to be unlined. Chimney linings help prevent toxic gases from leaking back into your home, threatening your health and safety. Unlined chimneys can also build up dangerous levels of creosote and tar that pose a fire risk as they cling to the bricks. If your chimney doesn’t have a liner, you should have one installed as soon as possible to protect your home.


The older your home, the more likely it is to find potential pyrolysis complications. Pyrolysis is a chemical reaction that causes organic materials, such as wood, to decompose when exposed to heat over a long period of time. After decades of constant fireplace use, the flammable construction materials near the fireplace become so dry that they can ignite easily. If you suspect your chimney is at risk of pyrolysis, you should schedule a chimney inspection.

Leaning Chimney

A strange slant on the chimney signifies that your chimney is beginning to lean away from the house. The cause of this is usually a deterioration of the chimney’s foundation, and it will require masonry work to put it back in place. A leaning chimney places enormous stress on the side of your home, and when the chimney does fall, it can take large pieces of the wall with it. Of course, a collapsing chimney is extremely dangerous to any people or property who might be nearby when it happens.
