Chimney Crown Repair and Rebuild
Chimney Crown Restoration and Rebuilding
The Critical Seal Against Connecticut Moisture
The chimney crown (the slab at the top of the chimney structure) is the primary weather shield for the masonry beneath. When a crown cracks or deteriorates, it allows water to penetrate the structure, leading to accelerated damage. We offer professional crown repair, sealing existing cracks, and complete crown rebuilding using reinforced, concrete-based materials designed to withstand freezing and thawing cycles common in Connecticut.
When minor cracking is present, we apply flexible, elastomeric crown sealants that bridge existing cracks and prevent water penetration while allowing the chimney to move naturally with temperature changes. This professional-grade restoration is crucial for maintaining the structural integrity of the chimney stack below the roofline.

Frequently Asked Questions (FAQs)
Cracks are primarily caused by the freeze-thaw cycle in New England, especially if the crown was constructed using standard mortar instead of reinforced concrete, which is not designed for continuous weather exposure.
Minor surface cracks can often be sealed with a specialized, flexible crown coat. If the crown has severe, deep cracks, missing pieces, or inadequate overhang, a complete tear-down and rebuild using reinforced concrete is necessary.
The crown should extend slightly past the chimney walls (an overhang or drip edge). This design ensures that water running off the crown drips clear of the vertical masonry, preventing erosion and saturation of the bricks below.
