Why Do Bricks Spall?

Chimney brick spalling is when the bricks begin to flake and crumble. In advanced stages, you may notice some bricks come loose or go missing altogether! This can happen for several reasons, but the most common reason is the weather. 

When moisture becomes trapped inside the bricks and then the temperature drops below freezing, the water in the bricks freezes. Since frozen water expands, when those bricks thaw, they become brittle and flake apart. 

Homes with frequent freezes and fluctuating temperatures will see chimney spalling much faster than warmer, more stable climates. If you live in an area with harsh winters, keep an eye on the damage starting around crowns, brickwork, and flashing.
