When chimney fires occur in masonry chimneys – whether the flues are an older, unlined type or are tile lined to meet current safety codes – the high temperatures at which they burn (around 2000′ F) can “melt” mortar, crack tiles, cause liners to collapse and damage the outer masonry material.

Most often, tiles crack and mortar is displaced, which provides a pathway for flames to reach the combustible wood frame of the house. One chimney fire may not harm a home. A second can burn it down. Enough heat can also conduct through a perfectly sound chimney to ignite nearby combustibles.

Common chimney conditions that can damage it:

  • Concrete crown cracked
  • Courses of bricks damaged
  • Flue liners cracked
  • No chimney cap
  • Presence of creosote

When the chimney concrete crown has weathered and cracked allows water to seep down into the holes of the top course (row) of brick and ultimately make its way throughout the entire masonry structure.

It is a necessary and normal occurrence for a chimney to take on a small amount of moisture, in other words, the chimney must “breathe.” The crown’s deterioration is permitting the chimney to absorb too much water.

This condition causes constant freezing and thawing during the winter months. At one time or another, you’ve probably seen chimneys where some of the brick “faces” are chipping, have completely popped-off, or have bricks missing all together. This is a condition called “Spalling,” and started because of no crown at all.

There is only one proper way to correct this problem. The old crown must be completely removed and then relayed with portland cement, not mortar. Mortar is used to lay bricks and will not stand up to the extreme temperatures and weather conditions found at the very top of the chimney.

You cannot relay a new crown directly on top of the failed one or fill the cracks with silicon sealant. If you allow either of those quick fixes to be performed, the freezing and thawing mentioned earlier will cause your money to have been wasted after one winter.
