Should You Waterproof Your Chimney

The bricks and mortar of a masonry chimney are porous and absorb large amounts of water. Waterproofing your chimney can extend the life of the exposed chimney walls. A common brick is like a sponge, absorbing water and wicking moisture to the chimney interior. The filling up with water then drying out wears the brick down causing chips, cracks and sometimes even breaking the brick in half or breaking pieces off. This wet/dry cycle also effects the mortar joints that hold the bricks together. As this mortar deteriorates, bricks loosen and can even fall out if not addressed. This water penetration can cause interior and exterior damage to your home and chimney. Of course, those homeowners who have annual inspections as recommended will know well in advance that these types of chimney repairs are coming and can plan to get repairs done as required.

Material Must be Breathable

There are many products that say they are waterproof, but you must be careful because not all chimneys are made up of the same materials. While brick and mortar are the favorite, there are also stucco and concrete chimneys that need to be waterproofed with a different substance. The product we use is breathable so, though it stops water from entering, it allows the smoke and carbon monoxide to flow through the brick and escape the chimney through the walls. It also allows the brick to move naturally with the seasons. Contact us and ask us more about what we can do for you in regard to waterproofing your chimney.
