Water penetration can wreak havoc on chimneys, leading to a variety of telltale signs indicating deterioration. Understanding these symptoms can help in addressing issues before they escalate into significant problems.
1. Degrading Mortar Joints
One of the initial indicators of water damage is the weakening of mortar joints. When mortar starts to decay, it loses its binding strength, potentially causing bricks to become loose and unstable.
2. Spalling Bricks
Spalling occurs when bricks start to flake, chip, or crumble. This happens because water infiltration causes masonry materials to expand and contract. Over time, this stresses the surface, leading to visible deterioration.
3. Cracks in the Chimney
Cracking is another common sign. Look for visible cracks in the chimney structure, as they can allow more water to seep in, worsening the situation. Addressing these cracks early can prevent further damage.
4. Chipping Masonry
Chipping or breaking off of masonry pieces is a clear sign of neglect and water-related damage. This not only affects the chimney’s functionality but also its aesthetic appeal and structural integrity.
Regular maintenance and inspections can identify these issues early, ensuring your chimney remains safe and effective for years to come.
How is it fixed?
Elbow grease is required to dig out the old cracked and dried grout. Repointing the chimney with new grout and fixing any broken or chipped bricks solves the water problem. After all of the entrances of water are blocked, the entire structure is waterproofed with a coating designed to last upwards of 10 years. Waterproofing chimney structures is a wise investment for your home.
A well done chimney seal will last for a decade or more. During your annual chimney sweep inspection, any issues with water or cracks will be corrected. This includes the chimney flashing area also. Water finds its way into any small openings, even if they are not obvious.
