Crowns are concrete slabs that cap the brickwork off at the top of your chimney. Chimney crowns are a very important part of your chimney. They prevent water from entering the void in your chimney and support the top of you systems flue. Repairing chimney crowns can be done by sealing the cracks, applying Crown Coat, or replacing the old damaged crown with a new one. At A-1 Safety Chimney Service, Inc. we recommend that you have your crown inspected at least once a year to prevent costly repairs by catching issues with you crown early.
