What Causes a Leaky Chimney?

Do you have a masonry chimney? If you do, you may already know that the likelihood of having a leaky chimney can be quite high. Why are masonry chimneys so likely to experience water leaks? The Chimney Safety Institute of America (CSIA) answers this question by stating that water is the biggest enemy of a masonry chimney. Every component of your chimney can possibly suffer expensive and extensive damage when water penetrates into your chimney. Stained ceilings or walls, loose bricks and chipped mortar on the exterior of your chimney, and musty or moldy odors coming from your fireplace are all signs of a leaky chimney. If you have seen any of these signs, it is crucial to contact a professional chimney company like Hudson Chimney to locate the source of the leak and make repairs so that your fireplace and chimney system can function safely and properly. But, what exactly can lead to a leaky chimney? We would like to tell you four problems that allow water to easily penetrate your chimney.

1. DAMAGED OR MISSING CHIMNEY CAPS

Chimney caps are your least expensive preventive measures against water penetration because they cover the top of your chimney. Freezing temperatures and destructive animals trying to get into your chimney can cause cracks and other damage your chimney cap. When your chimney cap is damaged (or even worse, missing completely), water from rain and melted snow can easily get into the masonry work of the interior of your chimney. Hudson Chimney offers a wide variety of chimney caps, and our certified technicians can install a custom-fitted cap to protect your chimney from water leaks.

2. DETERIORATED CHIMNEY CROWNS

Located directly beneath the chimney cap, a chimney crown is constructed from concrete and used to seal the opening of your chimney. Unfortunately, your crown could be made from the wrong or ineffective material, or it could be improperly installed. In these situations, damage and deterioration will occur sooner than later, and you will have an opening to your chimney where water can easily enter. The masons at Hudson Chimney can repair damaged chimney crowns as well as correctly install custom-made crowns to keep the water out of your chimney.

3. DAMAGED FLASHING

Flashing is sheeting made from metal that is placed between your chimney and your roof to protect this area from water leaks. Easily improperly installed, not every chimney company will the time to customize the flashing itself for a perfect fit. Our technicians will customize flashing by carefully measuring each part of your chimney and its surrounding areas on your roof so that it fits exactly and leaves no holes or cracks, which allow water penetration of your chimney.

4. WORN OUT MORTAR JOINTS

Water deteriorates the essential mortar joints that hold your chimney together and creates holes and cracks within the masonry. In the winter, water trapped in your chimney freezes and thaws, which leads to the bricks breaking and crumbling, and this will cause even more water leak problems. Fortunately, Hudson Chimney can do masonry repairs using the tuck pointing process. Once we have completed these repairs, we can apply a waterproofing treatment that will ensure that your masonry work in your chimney is protected from any water leaks in the future.
