Chimney Cap & Crown Repair

The chimney crown is the concrete or mortar wash that seals the top of your chimney stack and slopes water away from the flue opening and brick. The chimney cap sits on top of the flue and prevents rain, sleet, birds, squirrels, and raccoons from entering the flue directly. When either component fails, water pours straight into your chimney system, accelerating liner damage, rusting your damper, staining your firebox, and eroding mortar joints from the inside out — damage that can cost thousands of dollars to correct if left unaddressed.

Robert's Chimney Service repairs cracked, spalled, and failed chimney crowns using professional-grade elastomeric crown sealants and, where structural damage is too severe, full crown rebuilds with properly mixed mortar and the correct slope ratio. We stock and install stainless steel and galvanized multi-flue caps, single-flue caps with mesh animal guards, and top-mount damper caps that replace failed throat dampers and seal the flue when the fireplace is not in use.

Charlotte's summer thunderstorms and occasional winter ice accumulation are hard on chimney crowns. If your crown shows visible cracks, is missing sections, or if you've found animals or water in your firebox, call +1 (980) 480-4169 for a same-week inspection and cap or crown service.
