Chimney Crown Repair in Suffolk County
The chimney crown is the concrete slab that seals the top of your chimney masonry around the flue liner opening. A properly built crown slopes away from the flue to direct water off the chimney. Many Suffolk County homes — especially those built in the 1940s–1970s — have incorrectly built crowns: too thin, with vertical edges instead of overhangs, or made with mortar instead of concrete. These crowns crack within years. Once cracked, every rain event sends water directly into the chimney structure, deteriorating liner, mortar, and brick from the inside. Crown repair or replacement stops this immediately.
