Crown Repair/Replacement

The mortar crown, often called a crown cap, is a concrete-like surface at the top of your chimney. Its job is to shed water away from the flue and also keep water from entering the chimney chase. Cracks or missing pieces in the mortar crown can lead to extensive water damage in your chimney. Mortar crowns may be repaired with traditional masonry products or a specialized waterproof procedure called Crown Seal.
