CHIMNEY CROWN REPAIR IN DORCHESTER, MA
Your chimney crown is the first line of defense against water damage. Cracks and deterioration lead to costly repairs. Fix it now before it's too late.
What Is a Chimney Crown?
The chimney crown is the concrete or mortar slab that covers the top of your chimney. It surrounds the flue liner and slopes away from it to direct water off the chimney structure. A properly constructed crown is essential for keeping water out of your chimney system.
Unfortunately, many chimney crowns are built with inadequate materials or poor construction techniques. Over time, crowns crack, chip, and deteriorate—allowing water to seep into the chimney structure where it causes extensive damage.
Signs Your Crown Needs Repair
Crown Repair vs. Crown Replacement
Crown Repair: If your crown has minor cracks or surface deterioration, we can apply a flexible crown coat sealant that bridges cracks and prevents water intrusion. This is the most cost-effective solution for crowns with minor damage.
Crown Replacement: If your crown has major structural damage, large cracks, or missing sections, full replacement is necessary. We remove the old crown and pour a new one with proper materials, slope, and overhang to protect your chimney for decades.
Why Crown Repair Matters
Water is your chimney's worst enemy. When water enters through a damaged crown, it saturates the masonry and causes:
- Freeze-thaw damage that cracks bricks and mortar
- Rust damage to dampers and other metal components
- Deterioration of the flue liner
- Mold and mildew growth
- Structural damage requiring expensive rebuilds
