Signs Your Chimney Crown Needs Replacement

Warning signs

• ·Visible cracks or chunks missing from the top
• ·Brick below the crown spalling or losing mortar
• ·Water stains inside around the chimney
• ·Rust on the damper or flue tile cracks

Why crowns fail

Many crowns are built with regular mortar instead of a proper concrete mix, lack an overhang with drip edge, or have no expansion joint around the flue.

Repair or replace

Hairline cracks can be sealed with elastomeric crown coatings. Deep cracks or missing pieces call for a new poured crown with an overhang.
