Every spring, All American Chimney Service gets calls from customers about leaky chimneys. During the winter, chimneys can suffer a lot of spalling damage, which is when the water that has been absorbed in the bricks and mortar freezes, expands, and then thaws to create cracks and gaps in the chimney masonry work. These cracks and gaps allow water to leak into your chimney and cause even more damage. While this can be a common cause of chimney leaks, they can occur in other areas too. Our Chimney Safety Institute of America (CSIA)-certified chimney experts have years of experience in diagnosing and repairing chimney leaks. We would like to tell you about the most common sources of chimney leaks to help you find the leak in your chimney.
Gaps In The Bricks and Mortar
As we said earlier, spalling damage can create gaps and cracks in the bricks and mortar joints that allow water to easily leak into your chimney and home. According toImproveNet, water can enter into a broken mortar joint, travel through the brick holes, and be directed to a ceiling or wall. This can cause water stains on your ceilings and walls and even rotting of the wood in places. All American Chimney Service can repair the damaged bricks and mortar joints of your chimney to keep these leaks from occurring.
Damaged Chimney Crown
Sitting at the top of your chimney, the chimney crown is made of mortar and serves as the cover of your chimney that keeps water, birds, and animals from getting into the chimney. Since the crown is made out of mortar, it can also suffer from spalling damage and become cracked, which lets water enter your chimney. If you see water in the bottom of your firebox, you most likely have a damaged chimney crown. Not only can All American Chimney Service repair damaged crowns, but we can also construct and install a new one if your crown is damaged beyond repair.
The area where your chimney meets the roof is a very vulnerable area for water leaks, which is why you need a customized flashing system here. Consisting of metal sheets that wrap around the chimney, a flashing system forms a watertight seal of your chimney. Flashing can become damaged by weather and animals. When flashing is bent, water can easily get through the gaps and enter your home through the chimney. All American Chimney Service offers flashing installation and repair services that will keep your chimney safe from water leaks.
