Leaking Chimney FAQ


Here in the San Diego area, talk of the coming El Nino is a very hot topic. Since this weather event will bring more rain to our area, it is very important to be sure your chimney is in good condition. Even a small chimney leak can lead to major problems when heavy rains are in the forecast. At Weststar Chimney Sweeps, we take chimney leaks seriously for good reasons. The Chimney Safety Institute of America (CSIA) claims that water is the biggest enemy of masonry chimneys because of the amount of damage it can do. Water penetration can deteriorate your chimney so badly that it could be in danger of collapsing. This is why it is essential to ensure your chimney has no leaks before the arrival of El Nino. We would like to tell you more about the signs and causes of chimney leaks as well as a preventive service we provide to keep water from leaking into your chimney.

Sure signs of chimney leaks include peeling wallpaper, stains on the walls and ceilings, and dampness near your fireplace. You might even notice water standing in the bottom of your fireplace or stove. You can also see signs of chimney leaks on the exterior of your chimney. Cracked, broken, and missing bricks and pieces of mortar are the result of the damage of water penetration of your chimney. You may also notice rusting on your chimney cap or chase cover, and this also means water is leaking into your chimney.

What are the reasons behind chimney leaks?

Different things can cause chimney leaks. Most commonly, Weststar Chimney Sweeps finds chimney leaks that are caused by missing or damaged chimney caps. Cracked chimney crowns also lead to water penetration of a chimney. We have also found chimney leaks caused by damaged flashing systems and deteriorated bricks and mortar on the chimney structure. All of these problems can be solved by our CSIA-certified chimney technicians. We can install a new chimney cap to keep water, birds, and animals out of the chimney or repair cracks in chimney crowns. We can also repair damaged flashing and repoint bricks and mortar to replace the missing masonry materials.

How can Weststar Chimney Sweeps protect my chimney from water leaks?

We offer waterproofing services that can keep water from being absorbed into the bricks and mortar of your chimney. Using a formula that is 100% vapor permeable, we apply a layer of this formula to your entire chimney. Since this formula is vapor permeable, vapors and gases can still pass through the bricks and mortar and not become trapped within where they could cause even more damage. Waterproofing your chimney is an excellent way to prolong its life and to prevent water leaks from causing damage.
