What's happening
If you can see a gap opening between the chimney and the side of the house, or the stack is visibly tilting, the chimney is moving. Unlike most chimney issues, this one is structural — it points to a foundation, footing, or severe masonry-deterioration problem, and it tends to accelerate once it starts.
The short version: diagnose the real cause first — then fix that, not a guess. We start every job with an inspection.
What causes it
Footing/foundation settlement
An undersized or failing footing lets the heavy masonry settle and tilt.
Severe masonry deterioration
Decades of water damage and freeze-thaw rot the mortar core until the stack loses cohesion.
Water erosion at the base
Poor drainage undermines the footing over time.
Why it matters
A leaning or separating chimney can pull flashing open (causing leaks), crack interior walls, and in the worst cases partially collapse. This is the chimney problem most worth an inspection sooner rather than later.
How we fix it
We inspect to determine whether it's a footing/structural issue or masonry failure, then recommend the right path — which for a separating or leaning stack is usually a partial or full chimney rebuild on a sound base, with masonry repair where appropriate. We start with a thorough inspection.

Chimney Pulling Away / Leaning — frequently asked questions
Is a leaning chimney an emergency?
It can be. A clearly tilting or separating chimney should be inspected promptly — it's the one chimney issue we treat with urgency.
Can a leaning chimney be straightened?
Occasionally minor cases, but a stack that has structurally moved is almost always rebuilt on a corrected base for safety.
What causes a chimney to separate from the house?
Most often a settling or undersized footing, or severe long-term water/freeze-thaw deterioration of the masonry.
