Brick Is Not Waterproof
Pour a glass of water on a brick and watch. It does not run off. It soaks in. Every rainstorm does the same thing to your chimney, which stands above the roof with no eaves or gutters to protect it.
In Dallas, that water does damage two ways. In winter, a hard freeze makes the water inside the brick expand and pop the brick face off. In summer, the sun draws the moisture back out and leaves white, chalky salt stains behind. Year after year, the mortar gets softer and the bricks start to flake.
Dallas Chimney Care waterproofs chimneys in Dallas, TX with a breathable water repellent made for masonry. Rain stays out. Moisture that is already inside can still get out.
Signs Your Chimney Is Soaking Up Water
- White, powdery stains on the brick
- Brick faces that flake or pop off
- Dark, damp patches that stay wet after rain
- Moss or green growth on the chimney
- Soft, sandy mortar joints
- A musty smell from the fireplace
- Water stains on walls or ceilings near the chimney
Our Chimney Waterproofing Process
- Inspect. We check the brick, mortar, crown, cap and flashing and take photos.
- Repair first. Sealant does not fix cracks. Open mortar joints get tuckpointing, and a cracked crown gets crown repair.
- Clean. The chimney is cleaned so the product can soak in evenly.
- Seal. We apply the water repellent to the brick and mortar, and protect your roof and windows while we work.
- Check. We show you the finished work with photos.
Waterproofing Works Best as Part of a System
Sealing the brick handles water that hits the sides of the chimney. The top and the base need their own protection:
- A sound crown to shed water off the top
- A chimney cap to keep rain out of the flue. See chimney caps.
- Tight flashing where the chimney meets the roof. See chimney leak repair.
When all four are in good shape, a brick chimney can stay dry for decades.
