3 Common Causes of Chimney Deterioration

Post by : Admin


If you have a chimney in your home, you may not think much about its condition — until you notice deterioration. Chimneys are made of sturdy materials like brick and mortar, but they can still be damaged if they’re not properly cared for.

In this blog post, we’ll discuss some of the most common chimney deterioration causes.

Cracked or Spalling Bricks

Bricks are the most common type of material used to build chimneys. Over time, however, bricks can crack or spall (flake or scale), leading to further deterioration of the chimney.

Brick chimneys should be examined as soon as possible once the homeowner discovers the damage, such as cracks. If these issues aren’t addressed, the chimney might deteriorate to the point of collapse.


Your chimney is constantly exposed to the elements, which can lead to moisture damage and deterioration over time. Here are some of the most common causes of moisture damage to your chimney:

Cracks in the Chimney Brickwork

Like any other type of masonry, bricks can crack over time. These cracks can provide a path for water to enter your chimney and cause further damage. You can contact a CT chimney sweep for your repairs!

Animal Nests

Animals love to nest in warm, dry places like chimneys! Unfortunately, their nests can block the flue and prevent proper ventilation, leading to moisture buildup inside the chimney, which can cause extensive damage.

Cracks in the Chimney Flue

Another common chimney deterioration cause is cracks in the flue. Over time, the constant exposure to heat and cold can cause the flue to crack and crumble, eventually leading to a collapse.

In addition, water can seep into these cracks and cause even more damage. If you notice any cracks in your chimney, look up chimney repair near me because it’s important to have them repaired as soon as possible to avoid further damage.


Chimney deterioration causes are not unknown. It is a common problem for homeowners, but fortunately, it can usually be prevented with regular maintenance and inspections.
