What Chimney Caps & Crowns Involves

The cap and crown are your chimney’s roof. The crown is the sloped slab at the very top that sheds water off the masonry, and the cap is the covered screen over the flue opening that blocks rain, animals, and embers. When either fails, water and wildlife get in — and water is the number-one cause of chimney damage in our climate. Replacing a cap or sealing a crown is a small job that prevents some of the most expensive repairs.

• Stainless-steel or copper cap sized to your flue, with animal and spark screening
• Crown repair with flexible sealant, or a full crown rebuild when needed
• Removal of any existing nests or debris before capping
• Multi-flue caps for chimneys with more than one flue
• A check of the surrounding masonry for related water damage

Signs You Need Chimney Caps & Crowns

You need cap or crown work if:

• There is no cap on your chimney, or the old one is rusted or missing screening
• You hear or find animals (birds, squirrels, raccoons) in the chimney
• The crown at the top is cracked, chipped, or crumbling
• You get rain, moisture, or a musty smell from the fireplace
• Debris or nesting material keeps falling into the firebox

• We inspect the top of the chimney, crown, and flue opening
• We remove any nests or debris safely
• We install a correctly sized stainless or copper cap
• We repair or rebuild the crown so it sheds water properly
• We confirm the flue is protected and drawing correctly

Frequently Asked Questions

What does a chimney cap do?

A cap covers the top of the flue with a screen and lid. It keeps out rain, snow, animals, and leaves, and its spark arrestor stops embers from landing on your roof.

What is a chimney crown?

The crown is the sloped concrete or masonry slab at the top of the chimney that sheds water away from the flue and brick. A cracked crown is a leading cause of chimney leaks.

Why do animals get into my chimney?

An uncapped or damaged flue is an open invitation for birds, squirrels, and raccoons looking for shelter. A proper cap with screening keeps them out for good.

How long do chimney caps last?

A quality stainless-steel or copper cap can last 15 years or more. Cheap galvanized caps rust out quickly, which is why we install stainless or copper.

Can you repair a cracked crown, or does it need rebuilding?

Minor cracks can often be sealed with a flexible crown coat. Badly deteriorated crowns need rebuilding. We will show you which yours needs rather than defaulting to the bigger job.

How much does a chimney cap cost?

It depends on flue size and material. See our pricing page for starting prices, or call (815) 305-5510 and we will size it for your chimney.

Do multi-flue chimneys need special caps?

Yes. Chimneys with more than one flue can use individual caps or a single custom multi-flue cap. We size and fabricate the right solution for your chimney.

Will a cap stop my chimney from leaking?

A cap stops rain from entering the flue directly, but many leaks come from a cracked crown, flashing, or masonry. We check all of them. See our chimney repair service.
