Chimney Crown Repair in Houston, TX

The chimney crown is the sloped concrete or mortar slab that covers the very top of your masonry chimney. It is built to shed rainwater away from the flue and the brick below, so once it cracks, water has a direct path into your chimney and home.

Look for visible cracks or crumbling on the crown, water stains or dripping in the firebox, white chalky staining called efflorescence on the brick, and spalling or flaking brick near the top of the chimney. Any of these point to a crown that needs attention.

Minor cracks can usually be sealed with a flexible, waterproof crown sealant. If the crown is severely cracked, crumbling, or was built without the proper overhang and slope, a full rebuild is the longer-lasting fix. Our free camera inspection tells you which one your chimney needs.

Sealing a cracked crown costs less than a full rebuild, and the final price depends on the size of your chimney and the extent of the damage. You get a clear, itemized quote after your free inspection, before any work begins. Call 281-904-4674 to schedule.

A properly sealed or rebuilt crown with a quality waterproof coating can last many years. We recommend reapplying a crown coat every few years to keep water out as part of your regular chimney maintenance.

Houston's heavy rain and freeze-thaw swings put constant stress on chimney crowns. Once water gets through a crack, it can rot framing, rust the damper and firebox components, and spall the brick below. Catching crown damage early is far cheaper than repairing the water damage it causes.
