Methods for Fixing a Cracked Chimney

Whether gas or wood-burning, masonry fireplaces are commodious fixtures that, for many owners, are the definition of a home. However, cracks in the brick or the mortar joints between the bricks are early indicators that your chimney is in danger of failing. By filling up cracks in your brick chimney, you may prevent costly future repairs and keep you and your family safe by lowering the risk of chimney fires. Small splits that are present throughout the summer can enlarge dramatically by the following spring. The impact of rain, snow, and ice will be intensified if those larger splits in the outer block are neglected. The water then begins to make its way downward, occasionally in between the outer brick and the wall, and occasionally deeper inside, between the outer brick and the flue.

You depend on your chimney to direct smoke up and out, but if either the inner or exterior walls of the chimney crack, you could experience major issues. After 25 or 30 years of exposure, mortar joints between stones or bricks are likely to flake, wash out, or crack. What causes these fractures in your chimney? Serious issues could result. Colder climates’ freeze-thaw cycles are typically to blame. Moisture has the potential to penetrate the stonework, harming it as well as any metal fixtures it may be attached to, such as a satellite dish or lightning rod.

One reason for the disturbing, destructive feeling of a chimney fire is the cracking in a blocked chimney that extends from the flue to the outside. Those who have encountered chimney fires describe them as an instantaneous rush followed by a roar similar to a freight train. Only the fire service can put out a chimney fire once it has started because it must be put out from the top down. Any time you work on a roof, there is a chance of falling and suffering serious injuries. The higher the roof or the steeper the pitch of the roof, the greater the risk.

Blocks are held together with mortar. When the mortar is first applied, it is smooth and sturdy, but as the years go by, the elements pummel the mortar, causing it to collapse. Use a joint raker to remove the brittle, loose mortar, leaving the solid mortar in its place. Use a masonry carver and a careful touch with a hammer to remove more problematic, brittle mortar. Using a cable brush, remove any remaining mortar fragments.

You might have noticed some moisture in your attic. A leak in the chimney crown could be one of the causes. If your chimney has minute fractures, rainwater likely enters during heavy downpours. Due to shrinking, these fissures can develop even during new construction. Cracks in the mortar might also be brought on by strong winds. Mortar can take several months to achieve its maximum strength. Strong winds may cause tension during this curing phase. Due to this, contemporary builders frequently incorporate steel rods into chimneys while constructing.

Applying a transparent silane-siloxane water repellant to the bricks is one way to fix leaks in the actual bricks. Water vapor can escape thanks to the water repellant, but liquid cannot get inside the brick.
