What Causes Chimney Damage?
All year long, your chimney is exposed to a variety of weather conditions. The main concern is water damage. Liquids leak in between the bricks from melting ice and snow or precipitation. When the water freezes and thaws again throughout the freeze-thaw cycle, it results in a phenomenon called spalling. When spalling occurs, your masonry will eventually need services for reconstruction.
Brick or stone that has been spalled on its surface will pop, peel, or flake. This can eventually lead to the masonry crumbling. Leaks and water damage within the house might result from cracked masonry work as well. Usually, damaged masonry needs total reconstruction. Both the interior and exterior of your chimney are impacted by moisture. Even the inside metal components might rust as a result of water.
Your mortar joints could be badly impacted by the weather that comes with changing seasons, leading to cracking or disintegration. The presence of gaps between bricks is a typical indicator of this. Additionally, you might see some cracking. Damaged mortar joints allow moisture to enter your chimney, which causes the aforementioned issues.
