Chimney Crown Repair

Repair or rebuild of the crown — the concrete cap covering the top of the chimney — to stop water intrusion.

New flue tile extension on a repaired chimney crown

The crown is the sloped concrete or masonry cap on top of the chimney structure (different from the flue cap). It's the single most exposed surface on the chimney, and cracks in the crown are one of the most common sources of water damage inside the chimney system.

We repair minor cracking with a waterproof sealant application and rebuild crowns that have deteriorated beyond a simple patch.

Frequently Asked Questions

What's the difference between a chimney crown and a chimney cap?

The crown is the concrete/masonry surface covering the top of the whole chimney structure. The cap is the smaller cover, usually metal, that sits over the flue opening itself. Both matter, but they're different components.

Can a cracked crown really cause that much damage?

Yes — water entering through crown cracks can freeze and expand in winter, accelerating masonry damage throughout the chimney, not just at the top.
