What Happens in Case of Cracks?

Foundation Not Strong Enough

Sometimes the soil underneath the base of the chimney resorts to expansion or movement or is not able to bear the weight of the chimney. This causes the foundation of the chimney to get disturbed thus leading to cracking and splitting in the brick and mortar of the chimney.

You need to get your chimney checked and sealed regularly on an annual basis because even a tiny chip can cause the moisture to penetrate leading to frozen water. This frozen moisture leads to thawing and expands the surface of the crack which leads to bigger cracks and even more cracks.

Snowfall and Bad Weather

Extreme snowfall, winters and hail can also cause cracks in the chimney as snow accumulates the chimney cap causing it to constrict and when its summers the snow melts thus loosening up which also leads to many cracks.

Improper Construction

Improper construction of the chimney in the initial stage is also a common cause for cracks in the chimney. Sometimes there is no gap in the flue liner and the chimney which can cause many cracks while sometimes heavy construction in the nearby areas of the chimney can also cause movement in the ground which leads to cracks in the chimney.

Chimney and Trees

Similarly, antenna on top of hoes can put a lot of pressure on the chimney and the collision can lead to cracks.

No Drainage System

If there is no drainage system below the chimney such as a puddle of water stands there or water does not flow away then the water can cause many expansion problems and lead to cracks in the chimney due to the foundation of the chimney being disturbed.

No Flue Liner

If there is a sudden fire near the chimney then it could also lead to cracks in the chimney. Absence of flue liner in the chimney cap also leads to cracks.
