Over time the cement cap can develop cracks and it can also lose its cementatious value, causing it to turn sandy.
All of these scenarios are possible entry points for water. I recommend replacing the cement cap every 20 years.
Much of my work comes from inferior brick such as Old Chicagos and Sandlimes.
Wide Chimneys are very suceptible to Water Damage as they are a large target for rain water.
Raincaps are available for installation on top of fireplace flues and screens for above the furnace flues.
The chimney was hit by lightning. The top 23 ft. was rebuilt with matching brick and the following 20 ft. below had the mortar joints ground and tuckpointed.

This chimney was leaning away from the
house due to an inadequate footing.
The chimney was removed to the ground as well as the foundation and footing, before it was determined why the foundation failed below the chimney.
After installing a proper foundation, the chimney and both fireplaces were then rebuilt.
We used a more durable brick than the high maintenance Used Chicagos.
