We had an extension built over two years ago and this last week loads of cracks have appeared especially on the old external wall that was boarded over. Whta's going wrong here can anyone help?
There's movement in the ground, possible underpinning needed.. was the footings checked when the extension was built? as it has been over two years I would possibly rule out it settling. would be an idea to get this checked..
