Question 1

How to measure your wall correctly

Accepted Answer

Use a steel tape measure pulled across the top of the wall at its widest point. If the wall has been rendered or pointed over time, that can add 10mm to 20mm to the nominal width. Measure in two or three places along the run because walls are not always perfectly uniform.

Question 2

What to do if your wall is a non-standard width

Accepted Answer

If your wall width does not match any standard stone width allowing for the right overhang, you have three options. You can cut stones on site using a diamond blade, which is practical but creates waste. You can order a custom width if your supplier offers it, which suits large projects. Or you can adjust the wall slightly where it is at the foundation stage, which is the easiest solution if you are building rather than renovating.
