Are leaning chimney stacks 🏠 cause for worry?
The quick answer is not always…
A small degree of lean is quite common in old properties. But in some cases, a leaning chimney stack could indicate underlying issues that need attention.
How can you tell if a chimney is leaning too far, you may ask?
As an official guideline, a lean of more than 1mm in 100mm is deemed unsafe, but in reality it is often still considered stable.
It is best to get a professional surveyor to determine if it poses a significant risk. As part of our pre-purchase surveys, we carefully examine chimney stacks, checking for any excessive lean and ensuring it's clearly documented in our reports.
