Preserving the Integrity of Your Chimney Crown

A crown seal is a protective layer applied to the top surface of the chimney crown, which is the concrete or mortar layer that surrounds the chimney flue at the roofline. The crown seal acts as a waterproof barrier, preventing moisture from entering the chimney structure and causing damage to the masonry, mortar, and interior components.


Crown sealant provides a durable waterproof barrier that protects the chimney crown from rain, snow, ice, and moisture infiltration, preventing water damage to the chimney structure and interior components.

Prevention of Cracks

Applying crown sealant fills in existing cracks and gaps in the chimney crown, preventing further deterioration and structural damage caused by freeze-thaw cycles and weathering.

Increased Lifespan

A properly sealed chimney crown prolongs the lifespan of the chimney by preventing water-related damage, such as spalling, efflorescence, and mortar erosion, which can weaken the chimney structure over time.


Why is it important to have Crown Seal?

A crown seal is essential for protecting the chimney crown, which is the concrete or mortar layer that surrounds the chimney flue at the roofline. Over time, the chimney crown can deteriorate due to exposure to weather elements, leading to cracks and gaps that allow water to penetrate the chimney structure.
