I have attached photos for clarity. The majority are of the 2-storey addition that was built in the 80's, to our 1960's semi that was very poorly built.
The left wall is original house.
I should point out, the bottom floor of the extension (right) was originally a garage, now living room (back door bricked up, window extended down to give views of back garden)
What doesn't look right to me is that the lintel that would have been above the door looks like it doesn't go into the brickwork at the left. Also looks a bit odd that they cut half a brick under the lintel.
Far right of the window. Lintel doesn't appear to go far enough into the brickwork. Only a third of a brick??
Close up of crack running through brickwork.
Crack from a distance. Should we be worried? Pointings shocking isnt it? 
Kitchen window in original house. Replaced 2 years ago. Whats worrying is that row of header bricks. Whats holding them up??? Again, gotta love the pointing. Or lack thereof.
Is there anything I should be worried about?
