We have a crack running down the back of our property and it runs from the
bottom right of the window to the top right of the patio doors, it has cracked
one brick right down the middle. The crack was there when we moved in 3 years
ago and has not noticeably moved.

We recently had a home buyer survey carried out and he was not sure if it was
settling or something more serious.

Any suggestions would be appreciated.
