Pay Attention to Crumbling Chimney Bricks & Mortar

Older chimneys and those that have suffered damage often show signs of crumbling within the masonry. Bricks crack and dislodge, mortar joints decay, and leave gaps. When you catch these problems early, you can prevent potentially serious and unsafe operating conditions down the line.

Even if your chimney has been damaged for some time and has significant problems, the right chimney repair and rebuilding work can restore it to safety and make it perform as it was intended.

A lot of things can affect the bricks and mortar that were used to build your chimney.

Some of the more common reasons for masonry damage and crumbling include:

  • Normal house-settling
  • Earthquakes
  • A chimney footing that was built incorrectly and/or used inferior materials
  • Poor quality workmanship or cheap materials used in constructing the chimney
  • Major hail storms
  • Lightning strikes
  • Damage that begins internally due to excess acidic creosote in the flue and other causes
  • Cracks in the masonry that allow water to infiltrate and cause more serious damage
  • Year after a year of intensely hot and cold air temperatures

As you can see by this list, many common reasons for chimney masonry damage can’t be prevented: you can’t control the weather or seismic events, and you can’t roll back the age of your chimney. However, some types of damage can be prevented – and all types of damage can be repaired.

Assessing water damage to your chimney

A very common cause of a crumbling chimney is water infiltration. A leaky chimney will continue to get worse until large sections of masonry are showing loose or missing bricks and decayed

Water erodes chimney building materials. When the water inside cracks freezes, it expands (just like ice in your freezer) and pushes out against the surrounding material, breaking it apart.

Minor cracks in your chimney often can be sealed with a waterproof compound. This will prevent further water infiltration. More serious problems can be addressed through tuckpointing, during which crumbling mortar is scraped out and replaced with a strong new compound.

When extensive damage is present, partial or complete chimney rebuilding usually is necessary to restore safety and performance to your chimney.
