Chimney Crowns and Caps
The crown seals the top of the masonry and sheds water. The cap covers the flue. A cracked crown or a missing cap lets rain into the chimney, which is behind much of the damage we repair.
- CrownPoured or cast, sloped with a drip edge
- CapStainless or copper, with a screen
- PurposeShed water, keep out animals and debris
- SealFlexible sealant where the crown meets the flue

Common questions
How do I know my crown is bad?
Look for cracks, gaps between the crown and the flue and bits of crumbling cement. A good crown is smooth and overhangs the brick.
Can a cracked crown be repaired?
Small cracks can be sealed. Larger damage means rebuilding the crown, which is a small job compared with the damage it prevents.
Is a cap really needed?
Yes. A cap blocks rain, animals and sparks, and it is one of the cheapest ways to protect a chimney.
