Your chimney system is made of many working parts, that together do a very important job. Without your chimney the byproducts from your fire would be released into your home, causing health risk and increased chance of faq-chimney-crowns-img-boston-ma-billy-sweet-chimney-sweepfire. An important part of the chimney that keeps it working properly is the chimney crown, and it should not be overlooked.

What is a Chimney Crown

The chimney crown is a masonry slab that covers the top of the chimney from the flue liner to the edge of the chimney. The crown is designed to keep water from entering the flue, and guides the water instead to the roof. The chimney cap prevents water from entering the flue from the sky, and the crown prevents water from entering the flue from the edge of the chimney.

The chimney crown should be professionally installed, and is made specifically for each chimney. If the chimney crown is not the correct size or installed incorrectly then water will not only enter the flue, but can also pool around the chimney and penetrate the flashing.

Water and Your Chimney

Water damage is the single worst enemy of your masonry chimney. It can cause parts to rust, masonry to weaken and crumble, walls and ceilings to leak, and more. Avoid this costly damage by getting the job done right the first time.

Hire a Professional

A general contractor may be unfamiliar with chimneys, chimney crowns, and other vital chimney parts. To ensure that you’re getting the proper taper, overhang, and materials call Billy Sweet Chimney Sweep. A proper chimney crown should be constructed of a Portland cement-based mixture and cast or formed so it provides an overhang projecting behind all sides of the chimney by a minimum of two inches. Also, the flue liner should project above the crown a minimum of two inches.

A CSIA Certified Chimney Sweep® (CCS)  can not only construct a proper chimney crown, but is also experienced in assessing damaged crowns as well as repairing them.

Signs Your Chimney Crown Needs Repairs

Cracks, crumbled masonry, or chipping and flaking—known as spalling—as well as chimney leaks and leaks around the crown itself is cause for repair. An experienced and professional chimney sweep can assess damage and offer a fair rate to repair or replace the chimney crown. If damages are not extensive, our technician can apply a simple crown coat sealant, which will seal cracks, creating a water-proof barrier.

Your trusted chimney sweep will quickly assess damage and offer a repair plan that you can feel comfortable with. Our top priority at Billy Sweet Chimney Sweep is the safety of our customers.
