However, we would like to tell you more about our chimney waterproofing. It is one of our highly recommended services. It is also highly effective when it comes to protecting the bricks and mortar joints of your chimney from water.

Why does so much chimney masonry damage happen during the winter?

According to the Chimney Safety Institute of America (CSIA), water causes a great deal of damage to masonry chimneys. Since bricks and mortar joints are porous, they easily absorb water from rain and melted ice and snow. In the winter, this absorbed water then freeze and expand as the temperature drops below freezing. As the weather warms back up, the force of the water thawing is strong enough to make the masonry materials crack and break. This process of masonry deterioration is the freeze/thaw cycles, and it occurs over the winter. If this damage is not addressed timely, it puts the structural soundness of your chimney in serious jeopardy.

How can professional waterproofing protect my chimney from masonry deterioration?

When All American Chimney Service comes to your home to perform this preventive care, we begin by scrubbing the exterior of your chimney clean. We then apply a waterproofing formula that is specifically made for chimneys to the entire exterior structure, this helps to create a barrier against water penetration. The formula we use is much better than paint or another type of sealant because it is 100 percent vapor permeable. This means vapors and gases can escape instead of becoming trapped inside the masonry materials to cause further damage. Once we have completely finish waterproofing your chimney, it is then safe from masonry deterioration for at least a decade.

Make sure your masonry chimney can withstand the cold and harsh winter weather.Contactustoday at502-435-2364at All American Chimney Service to schedule an appointment for our professional chimney waterproofing services.
