Chimney Crown Repair & Replacement in Boston, MA

The chimney crown serves as the first line of defense against water entering your chimney system. Chimney Goat offers professional chimney crown repair and replacement services in Boston, MA, ensuring your masonry is protected from the destructive effects of rain, snow, and ice.

The Role of the Chimney Crown

A properly constructed chimney crown covers the top of the masonry walls and slopes downward to direct water away from the flue and the brickwork below. When the crown cracks or deteriorates, water seeps into the chimney, leading to severe freeze-thaw damage, spalling bricks, and interior leaks. In Boston’s climate, a compromised crown can cause significant damage within a single winter season.

Crown Sealing and Rebuilding

For minor cracks, we apply a flexible, waterproof crown sealant that bridges the gaps and prevents further deterioration. If the crown is severely damaged or was improperly constructed, we remove the old material and pour a new, reinforced concrete crown with a proper overhang and drip edge. This ensures long-lasting protection and prevents future water intrusion. See our full chimney leak repair services for more information.
