Protect the Masonry on Your Chimney With Water Repellent

Because chimneys are exposed to the elements, they incur all kinds of weather damage. Whether it’s the freezing temperatures of the winter or spring showers, your chimney is bound to experience structural damage over time.

Water damage, specifically, is incredibly harmful to your chimney, and it’ll require expensive repairs. Water that has managed to leak into your chimney can cause decay in the drywall, weaken the structural beam through rot, and ruin the flooring in the house under the chimney.

You can prevent paying hundreds of dollars (if not more) for repairs by either waterproofing your chimney or applying water repellent to it.

Why Is Water in the Chimney So Problematic?

Masonry made of brick and mortar absorbs rainwater and water from melting snow, similar to a sponge.

Once the water seeps into the masonry, it expands and contracts; the freezing of water in the cracks will cause the masonry to weaken and fall apart. Unless the masonry is repaired, it will lead to more structural issues in the future.

Exposure to water impacts the chimney greatly, but it also flows into other parts of the house, including the floor, ceiling, and critical structural beams.

How Does Treating a Chimney With Water Repellent Help?

Treating your chimney masonry with just about any water repellent can hamper its absorbent properties. A chimney should only be treated with a water repellent that’s specifically designed to be used on it.

Fireplaces must allow poisonous gases, heat, and water condensation to pass through them. Generic water repellents will completely seal the masonry and stop it from “breathing.” As a result, the gases, water vapor, and heat will remain in the house.
