Damaged chimney crowns are one of the leading causes for masonry chimneys falling into disrepair. If left unattended, even minor cracking will cause deterioration by allowing rainwater to penetrate into the masonry of the chimney. A newly poured flexible seal or crown is your best bet for preventing costly masonry repairs in the future.
Chimney leaks can be caused by a number of things which often makes them difficult to pinpoint. Not knowing the source of the leak or how to address and solve the problem can be incredibly frustrating and makes repairs impossible. At Chimney cleaning Atlanta our Technicians have years of experience and knowledge to help in troubleshooting. We know where to look first and what to do when we find the cause of the leaks.
The crown is the cement layer that sits on top of the chimney stack. If it is deteriorating, too thin, or improperly sealed or cracked it can allow water into the top of the chimney.
Flashing consists of several layers of metal that overlap where the roof meets the chimney. These layers travel up the sides of the chimney a ways, and protect this sensitive area from water invasion. If the flashing is damaged or missing, leaks are inevitable. For more information on flashing, check out our Chimey Flashing page.
A chimney cap works in conjunction with the crown to keep out water, debris, and animals. When the cap is missing, rusted or damaged, it can leave the chimney vulnerable to leaks and water damage.
