The chimney crown is one of your chimney’s most important defenses against weather and intruder-related damage and decay. Unfortunately, not all crowns are created equal, and not all crowns provide the same level of protection. Is your chimney crown living up to its duties?
The chimney crown refers to the concrete area at the top of your chimney, just below the cap. If designed and installed properly, the crown will work to divert water away from the masonry of your chimney and away from your home, and will also help to keep animals and debris from entering the chimney system. It’s not common to find a chimney without a crown, but it is common to find a chimney with a sub-par or deteriorating crown.
A good, properly designed and installed chimney crown should be built of a quality concrete and mesh/fiber mix, and should be smooth and sloped, to encourage water runoff. It’s also incredibly important that the crown be of proper thickness, and that it be properly sealed and extend past the masonry of the chimney. Unfortunately, we find that many chimney crowns are too thin and flat, inadequately sealed, and simply end where the chimney ends. Crowns like that never last for long, and can quickly deteriorate and lead to leaks. Is your chimney adequately protected?
If your chimney crown is cracked or crumbling, or if you notice any discoloration on your masonry (i.e. change in brick shade, white staining, or signs of vegetation), it’s highly likely that you have a water problem, and that your crown needs repairs or a complete replacement.
Because water is so damaging to your chimney system and home, it’s important that you seek professional help as soon as you notice any of these signs. The technicians at A-1 Chimney Specialist have extensive experience identifying leaks, and can repair or replace your crown quickly and properly. We will not only provide you with a crown that is built to last, but we can also make waterproofing recommendations to further protect your chimney.
