I have a semi-detached 3 storey town house that is 13 years old. Have owned it since it was first built.
When it was new there were no cracks inside or out. In the last 6 months there has been a crack appear outside -firstly into the side of a window on the second floor, about a metre long, and then a smaller one into the corner of a first floor window. Today a third has appeared coming out of the same second floor window.
Internally, coving has started to move away from walls and split in the corners (where previously everything was smooth - now there are cracks). I also think that the architrave is coming apart at the joints (gaps where there were none before?).
I think the house is moving!! DH thinks I am being silly....
If I need to get someont to inspect- who?
