The leading chimney industry expert, the Chimney Safety Institute of America (CSIA) has declared that water is the worst enemy of your masonry chimney. From the first early signs of water penetration damage such as loose bricks and mortar to serious, extensive and expensive trouble like tilted or collapsed chimney structure, water leaking into your chimney can cause an enormous amount of destruction. You may have even seen signs of water leaks on the exterior of your chimney such as deteriorated mortar joints and loose bricks after winter is over. When water gets into the bricks and mortar of your chimney and freezes, expands, and thaws, it causes stress and spalling damage to the masonry work and structure. Luckily Mr. Smokestack is ready to help keep the water out of your chimney. We would like to share with you three water leak preventive measures recommended by the CSIA.
The solution to keeping water out of your chimney can be the simple and inexpensive professional installation of a new chimney cap. Responsible for important tasks like protecting your chimney from penetrating water and invading birds and animals, helping keep a proper draft, and preventing sparks from exiting your chimney to possibly ignite a fire, chimney caps come in a variety of different metal materials and types. Mr. Smokestack sells and installs various chimney caps, and our certified chimney technicians will know exactly which cap is the perfect fit for your chimney. Constructed from galvanized metal, stainless steel, or copper, chimney caps also vary in type, such as a standard cap, a chimney cap damper, a spark arrestor, a draft-increasing chimney cap, or a custom-made cap. The staff at Mr. Smokestack will aid you in selecting the best cap for your chimney, which we will install.
Keeping water from pooling in the seams where your chimney meets the roof, correctly fitted and installed flashing also protects your chimney from water leaks. Providing professional custom flashing construction and installation, the technicians at Mr. Smokestack Chimney Service use several layers of metal flashing that has been carefully cut to match our measurements of the area. We start with placing L-shaped step flashing around the bottom of your chimney by integrating it within your roof shingles. Next, we install counter flashing on top of the step flashing into the mortar joints of your chimney. After the flashing has been placed, all of its edges are covered with protective caulk to ensure your chimney is protected from water penetration.
A professional application of a waterproofing formula to your chimney can reduce the need for repairs and extend the life of your chimney. With years of expertise and experience, the specialists at Mr. Smokestack use a waterproofing sealant that has been especially made for masonry chimneys and is 100% vapor permeable. This is essential because it allows your chimney to “breathe” by letting vapors and gases escape while protecting the masonry work from water penetration. An affordable investment, waterproofing will save you dollars in future repair work from water leak damages.
