How to Repair a Chimney Crown

Chimney crowns are more than decoration on the top of the chimney. They are designed for protection. Often damage to the chimney crown goes unnoticed because it's an area of the structure that homeowners never see unless they are on the roof inspecting the chimney.

Very small, minor cracks in the chimney crown can be reparied with a good waterproof sealant to prevent further expansion.

What Causes Cracks in a Chimney

There are multiple reasons why a chimney can get cracks. Small hairline cracks in the bed mortar can be caused by normal shrinkage of the chimney and is an easy fix. Tension on the chimney caused by wind pressure can also cause continuous cracks through the brick or block masonry. Another common cause is settlement. If the soil that the chimney rests on is not strong enough to support the massive load placed on it then it can cause issues such as cracks.

If you discover cracks in a new chimney this is typically the result of improper construction of the chimney.

Chimneys that are weakened by a defect during the building process or even by natural deterioration can be very dangerous. With little to no warning, weakened chimneys can collapse causing injury or even death.
