What Is Chimney Waterproofing?
Buffalo, NY, is a beautiful city on the shores of Lake Erie and is drenched with history. However, the harsh winters can cause significant damage to homes and chimneys in the region. As we mentioned in our previous blog posts, masonry chimneys are particularly vulnerable to water damage, a primary concern in Western New York’s cold climate and frequent snowfall. We recommend chimney waterproofing to protect your chimney and masonry from water damage.
When waterproofing a chimney, we apply a specialized protective coating to the exterior of your chimney that prevents water from seeping into the masonry. The water-based formula also repels snow and ice. It is vital in maintaining your chimney’s structural integrity and protecting your home from water damage.
Is Chimney Waterproofing Important?
While water is the foundation of life, it is masonry’s mortal enemy. When moisture seeps into the stonework or bricks and mortar of your chimney, it can cause many problems, including:
- Efflorescence: This is a white, powdery substance that forms on the surface of masonry when water evaporates and leaves behind mineral salts that rise to the surface. It’s often the first sign that your masonry is compromised.
- Cracks and mortar joints: Water will eventually erode the mortar joints between the bricks, weakening the chimney structure and making it more vulnerable to leaks and spalling.
- Spalling: When the bricks and mortar deteriorate, the face of the bricks crumble and pops off due to spalling. It occurs when the expansion and contraction of water during freezing and thawing cracks the masonry.
- Corrosion: Water can also corrode the metal components of your chimney, such as the flashing and crown, allowing moisture to seep inside the chimney.
Should I Waterproof My Chimney?
Yes, it is important to waterproof your chimney. Even though bricks and mortar can withstand the elements, they are not entirely waterproof. Over time, exposure to rain, snow, and ice can take a toll on your chimney and make it more susceptible to water damage. The deterioration accelerates when the masonry already has some wear, such as corrosion, efflorescence, cracks, and spalling.
How Often Should I Waterproof My Chimney?
Typically, chimney waterproofing should be reapplied every 5-7 years. You should apply it more often in areas with above-average precipitation. It is also vital to have your chimney inspected by a Certified Chimney Sweep® every year to check for signs of water damage. Also, the process requires professional-grade, vapor-permeable water repellant designed for masonry chimneys. So, it is not a DIY job. Here at Felgemacher, we protect chimneys with ChimneySaver®.
