Chimney Caps

A chimney cap is a protective covering installed at the top of your chimney to prevent water, debris, and animals from entering. It plays a crucial role in maintaining the safety and efficiency of your chimney system.

We help homeowners protect their chimneys with durable, properly fitted chimney caps.

chimney Cap Installation & repair services

Properly installing or repairing a chimney cap requires a combination of precise measurements, technical expertise, and strict safety precautions. Because the cap sits at the absolute highest point of your home, it bears the brunt of harsh weather and requires a rock-solid fit to prevent leaks, draft issues, or detachment during high winds. Below is a step-by-step overview of how professionals inspect, repair, and securely mount a chimney cap for long-term protection. Our services include:

Chimney Crown

A chimney crown is the top protective layer that seals and shields your chimney from water damage and weather exposure. Proper chimney crown maintenance helps prevent costly structural issues and extends the life of your chimney system.

We help protect your chimney crown by addressing key issues early before they turn into major repairs.

Chimney crown installation & repair services

Repairing or installing a chimney crown demands meticulous masonry technique, specialized materials, and precise slope engineering. Because the crown sits continuously exposed to severe thermal cycles and harsh weather, taking shortcut methods with standard mortar or spackle will quickly lead to failure. Below is how trained technicians inspect, patch, or construct a durable, custom concrete crown built to last.

Common warning signs include:

If you notice these issues, your chimney crown likely needs immediate attention to prevent further damage.

Frequently Asked Questions

What is the difference between a chimney cap and a chimney crown?

The chimney crown is the flat or sloped concrete slab that covers the top of the brick-and-mortar structure to protect the brickwork from rain. The chimney cap is the metal cover mounted above the open flue pipe(s) to keep water, animals, sparks, and debris from falling directly inside the venting system. Think of the crown as the roof of your chimney, and the cap as the umbrella over the flue pipe.

How do I know if my chimney cap or crown is leaking?

Common signs of a leaking cap or crown include water or dampness inside the firebox, rust on the fireplace damper, a musty odor coming from the hearth, water stains on adjacent ceilings or walls, and crumbling mortar/flaking bricks (spalling) near the top of the chimney.

Can I repair a cracked chimney crown myself, or does it need to be replaced?

If the crown only has minor hairline cracks, it can usually be repaired and sealed using a specialized, flexible elastomeric crown sealant to stop water intrusion. However, if the concrete is crumbling, missing chunks, or structurally failing, a partial patch won’t last, it will require a complete tear-off and a fresh pour of reinforced concrete by a professional.

Why can’t I just use regular mortar to fix my chimney crown?

Standard masonry mortar is designed to bind bricks together, not withstand pooling water, harsh freeze-thaw cycles, and direct sun exposure. Mortar absorbs moisture quickly and will crack within a few seasons when exposed on top of a chimney. A proper crown requires a high-strength, fiber-reinforced Portland concrete mix (or elastomeric masonry sealants for minor repairs).

How often should chimney caps and crowns be inspected?

They should be inspected at least once a year during your routine professional chimney inspection and sweep. Catching minor cracks in a concrete crown or a loose seal on a chimney cap early prevents thousands of dollars in water damage to the underlying masonry and interior walls.
