The Chimney Crown: Protecting Your Chimney from the Top Down

The chimney crown may not look like much at first glance, but it’s one of the most crucial features of your entire chimney system.
Located at the very top of a masonry chimney, the crown’s job is simple — to keep water out.

A properly built and maintained crown seals the top of your chimney, directs water away from the flue and brickwork, and protects everything below from costly damage.

Professional Crown Repair and Concrete Application

Our professional team specializes in chimney crown repair, resurfacing, and rebuilding using durable, weather-resistant materials.

When possible, we restore the existing crown using crown concrete application 0- a high-quality, waterproof concrete mix applied to seal cracks and reinforce the surface.
This creates a smooth, durable barrier that sheds water effectively and prevents further deterioration.

If the crown is too damaged, we rebuild it completely, ensuring proper slope, overhang, and seal around the flue.

Our process includes:

Cleaning and preparing the crown surface.

Applying a waterproof crown coating or new concrete layer.

Repairing cracks and sealing joints.

Installing a properly sloped surface for drainage.

Every repair is designed to extend the life of your chimney and prevent costly water damage down the line.

Protect Your Chimney Where It Matters Most

Your chimney crown may be out of sight, but it plays a vital role in keeping your fireplace and chimney dry, safe, and structurally sound.
Regular inspection and professional concrete application can save you from expensive masonry repairs later.

Our expert team ensures your crown is built and sealed to last — keeping water out and protecting your chimney from top to bottom.

and let our professionals apply durable crown concrete to keep your system strong and watertight.

What Is a Chimney Crown?

The chimney crown is a sloped layer of concrete or cement that sits on top of the chimney structure, covering the masonry and surrounding the flue tiles.

Its purpose is to:

Seal the top of the chimney to prevent rain, snow, and debris from entering.

Divert water away from the brick sides and mortar joints.

Protect the flue liner and interior chimney from moisture intrusion.

Without a proper crown, water can seep into the chimney’s masonry - leading to cracking, spalling, and even structural failure over time.

Why the Crown Is So Important

The chimney crown’s job is simple but vital: keep water out.
Moisture is one of the biggest enemies of any masonry structure. When water seeps into the bricks and mortar joints, it expands during freezing and thawing cycles, causing cracking, spalling, and leaks inside the home.

A damaged or missing crown can lead to:

Water leaks inside the fireplace or walls

Cracked or crumbling masonry

Rusting of metal components (like the damper or firebox)

Mold and odor problems

Reduced structural integrity of the chimney

That’s why our professionals always inspect the crown during chimney service visits — catching even small cracks early can prevent major repairs later.

Common Chimney Crown Problems

Over time, crowns are exposed to years of heat, moisture, and weather - and even the best-built ones eventually show wear.
Here are some common issues our team encounters:

Cracks or hairline fractures from temperature changes

Improper construction (flat instead of sloped crowns)

Erosion or crumbling concrete from poor materials or age

Gaps between the flue and crown allowing water intrusion

Lack of drip edge causing water to run down the chimney sides

These issues might start small but can quickly lead to leaks, damaged brickwork, and unsafe conditions if left untreated.

Long-Term Protection and Maintenance

A properly built and sealed crown can last decades with regular maintenance.
During routine inspections, our team checks for early signs of cracking or weather damage and applies protective treatments as needed to extend its lifespan.

By addressing small issues early, you can prevent expensive repairs - and protect your home from leaks and structural damage.
