Wall #1: The first wall is just a fence around the property but somehow it can be moved by bare hands with a bit of force. It doesn't appear to be in immediate danger of falling over but it's wobbly it seems like the mortar between this wall and the structural wall next to it have failed. Wall #2: part of the carport structure is connected to this and seems like a whole bunch of bricks have decided to give way. Can't be moved at all but because of the movement, the picket fence gate next to it no longer sits straight. I'm not 100% sure if this bit of the wall is used to support the carport. So...do I need a builder or structural engineer to sort this out? Thanks in advance.
