If the ground or footing surrounding your chimney is not stable it could create the perfect environment for your chimney to shift. An unstable foundation is the leading cause in chimney shifting.

The quality of your chimney

A chimney that is not properly built from the start risks structural damage. Over time the structure could begin to lean because the masonry is not strong enough to support it


We often discuss that water is a chimney’s worst enemy and that is no different when it comes to a leaning chimney. If water damage is allowed to continue the masonry becomes damaged to the point where the structure itself may begin to collapse. As the brick and mortar decays through the freezing cycles of the winter the structure becomes less and less sound, which can easily lead to a leaning chimney.

Masonry Damage

As we mentioned above masonry damage can easily lead to a chimney leaning and eventually collapsing. The longer masonry damage goes unchecked the more dangerous the chimney can become if it is leaning, crumbling, were deteriorating in any other way.

Warning signs of a leaning chimney

While it may be obvious by looking at your chimney that it is leaning, it may not always be clear to the naked eye. If your chimney is not leaning to the point that it is noticeable simply by looking, that does not mean you are in the clear. Let’s talk about a few of the warning signs that your chimney is beginning to lean.
