Hi anorthernguy Don’t worry about the masonry cracks these are normal for the installation method used. The sagging of the door should be addressed and it may be a matter of adjusting the hinges to get a better fit. Regards S
I stupidly googled cracks in mortar and you can imagine the results. I just didn't want to go through the whole sale to find out the house is subsiding and it all fall through.
I think it may just be the weight of the door has pulled the frame down slightly over time, I might get someone to come and have a look at the PVC and straighten it up as the lintel is still straight above it.
