Your chimney’s mortar crown, also called crown cap, is the surface located on the top of your chimney. It needs to be able to shed the water and prevent moisture from entering your chimney. Breaks and cracks in your chimney’s crown will slowly lead to water damage inside of your chimney. We can repair or replace your chimney cap and give it a leak-proof crown seal. The joints that are between the liner tiles will continue to break down over time. This erosion will eventually let heat, gases, or creosote enter your home. Additionally, water will freeze and thaw, leading to expansion damage. A well-maintained chimney cap will prevent moisture from entering the top and causing problems.
