Restore Your Chimney's First Line of Defense
Since 2015, The Chimney Guards has helped homeowners throughout San Francisco and surrounding Bay Area cities prevent water damage and extend the life of their chimneys through reliable chimney crown repairs. The crown is one of the most critical—and often overlooked—parts of your chimney. When it fails, your entire chimney system is at risk.
Whether it’s a small crack or significant deterioration, we have the experience and tools to repair or rebuild your crown for long-lasting protection.
Why Chimney Crown Repair Is So Important
The chimney crown is the concrete or mortar top layer that seals the opening around the flue and slopes outward to divert water away from the chimney structure. Over time, the crown can develop cracks from weather exposure, freeze-thaw cycles, or poor construction.
If left unrepaired, a damaged crown can:
Allow water to penetrate the bricks and mortar
Lead to leaks inside your chimney or home
Cause internal rusting and decay
Accelerate brick spalling and mortar erosion
Increase the risk of structural instability
Repairing the crown early helps avoid much more expensive repairs down the road.
Our Chimney Crown Repair Services Include:
At The Chimney Guards, we offer a full range of chimney crown repair options tailored to the level of damage and your chimney’s design:
Crown Sealing: For small cracks, we apply a flexible, waterproof sealant that prevents further moisture penetration and damage.
Crown Resurfacing: For worn or weathered crowns, we apply a durable cement coating that restores the surface and enhances water resistance.
Crown Rebuilding: If your crown is severely cracked or crumbling, we’ll remove the damaged material and rebuild it with high-quality concrete, properly shaped and sloped for water runoff.
Crown Inspection & Maintenance: We also offer annual inspections to catch minor issues early and keep your chimney sealed and protected.
All work is done to code using professional materials designed to withstand the Bay Area’s unique climate conditions.

Frequently Asked Questions About Chimney Crown Repair
What is the purpose of a chimney crown?
The chimney crown protects your chimney from rain and moisture by sealing the top and directing water away from the structure.
How do I know if my chimney crown is damaged?
Visible cracks, chips, or flaking concrete are signs. Water leaks and rust inside the fireplace may also indicate crown issues.
Can a damaged chimney crown cause leaks?
Yes. A cracked or deteriorating crown is one of the most common causes of chimney leaks.
Is sealing the crown enough, or will I need a rebuild?
It depends on the severity of the damage. We’ll inspect the crown and recommend either sealing, resurfacing, or rebuilding.
How long does a chimney crown repair last?
With proper materials and installation, crown repairs can last 10–20 years or more—especially with regular inspections.
What materials do you use for crown repairs?
We use high-strength concrete and professional-grade crown sealants designed to withstand temperature changes and moisture.
Do chimney crowns come standard with every chimney?
They should, but some older or improperly built chimneys may lack a proper crown, which we can install for added protection.
