The chimney crown is the concrete or mortar slab that caps the top of your chimney's masonry and directs water away from the flue opening and the brick below. Because it is constantly exposed to UV radiation, freeze-thaw cycles, and rain, the crown is one of the first components to deteriorate. Even small cracks allow water to seep in, where it freezes and expands during winter nights and aggressively widens the damage season after season.
Campbell Brothers Chimney Sweep assesses crown damage on every rooftop inspection and classifies repairs from simple sealant application for hairline cracks all the way to full crown removal and rebuild using properly mixed, overhanging concrete with a drip edge. We use elastomeric crown sealants rated for extreme thermal movement that bond to existing concrete and flex without cracking, significantly extending the life of the repair.
Left unaddressed, a failing chimney crown allows water to saturate the brick, damage the flue liner, and stain interior ceilings and walls. Because Charlotte experiences periods of heavy rainfall and occasional freezing temperatures, timely crown maintenance is a cost-effective way to prevent the far more expensive repairs that water infiltration eventually causes.
