chimney crown rebuldingThe chimney crown is an important part of the chimney system. It is the area around the top of the chimney that acts as an umbrella for the entire chimney structure. The chimney crown is not to be confused with the chimney cap, which is an attachment that is added to the top of the flue pipe to keep debris out of the chimney flue. The chimney crown tops off the masonry walls of the chimney with a small concrete roof that prevents water from seeping into the bricks and mortar that make up your chimney. This simple structure can actually save homeowners thousands of dollars in costly water damage repairs.

Chimney Crown Sealing

If a chimney crown becomes cracked or damaged, water and moisture can seep into the vulnerable masonry material of your chimney system and start deteriorating from the inside out. Repair or sealing is the best solution for a failing chimney crown and can save you from dealing with costly structural chimney repairs that could occur if the problem is neglected.

Chimney crown sealant can be applied to a chimney crown that has a few minor cracks. This waterproof seal helps keep water from soaking through the brick, mortar, and concrete that makes up your chimney.  Larger cracks are filled with high bond patching material and then Crown Sealing in applied over the top of the whole chimney crown. The sealant forms a waterproof membrane between the elements and your chimney. When properly applied, these solutions can add up to 15 years to the life of a chimney crown that has begun to wear.

Chimney Crown Rebuilding

If your chimney crown has begun to show its age, it may be time to replace it with a new concrete chimney cap before it is too late. If the crown has pieces missing or is lacking structural integrity, it’s best to replace and rebuild the chimney crown. Some inexperienced masons will simply use mortar mix to create a new top for the chimney. 

Chimney Crown Repair in Avon CTThe problem with this solution is that mortar mix will crack and leak very quickly since it is not a weather resistant material. A cement chimney crown that is properly designed to overhang the outside dimensions of the chimney structure is the best solution, and the one we prefer using on most chimney crown rebuilds.

Pre-cast or cast in place concrete crowns that are reinforced with steel are good solutions as well. Crowns can even be made of metal or stone, as long as they are water-tight and weather resistant. The top surface of the chimney crown is constructed to slant away from the center, diverting as much water away from the chimney as possible. This design helps keep water from running down over the bricks of the chimney, keeping your chimney structure as dry as possible.
