Chimney Crown Repair & Rebuilding

A lot of major chimney problems begin with a cracked or deteriorated chimney crown. Chimney Sweep Inc. of Lakeside, CA, has been solving chimney crown issues for our customers since 1985. If it’s time to repair or rebuild your crown, call in the experts.

What Is a Chimney Crown?

Chimney crowns are cement slabs that cover the entire top of the chimney except for the flue openings. When built correctly, crowns are sloped so water can run off them.

The purpose of a chimney crown is to keep water and debris out of a chimney's interior and away from the brick and structural rebar below the crown. When water moves in, serious trouble can follow:

Brick and mortar damage
Chimney liner damage
Fireplace damage
A chimney that begins to lean
A chimney collapse
Damage to the walls and other building materials of the home
Musty odors and mold growth

How Do Chimney Crowns Become Damaged?

We’ve seen crown damage from all kinds of sources, including:

Inferior materials used in building the crown
Improper workmanship
Lightning strikes
Pounding hail
Year after year of rain and high air temperatures
Old age

Chimney Crown Repair Projects

When a crown has minor cracks, it can often be repaired. After repairs are made, we like to use a product called CrownSeal by ChimneySaver, a leader in protective solutions for chimneys.

When applied properly, CrownSeal carries a 10-year warranty. It creates a flexible covering that will not break should materials beneath it shift. The color of the sealant is that of natural cement and mortar.

Chimney Crown Rebuilding Projects

When a crown is severely deteriorated, our experienced masons will correctly remove the old crown and lay a strong Portland Cement-based mortar crown. The new crown will provide superior protection for many years and look good while doing it.
