My sons just had a new composite door installed with frame. Clearly the frame is not square, (fitters trying blame it on the plasterer boarding the ceiling in the same room) .
The thickness of the frame is larger than that of the door by around 4mm so the keep to the frame does not reach far enough forward as can be seen below.
This means the door part contacts the frame when closed and is marking the plastic. The latch can be caught behind the edge of the profile leading to it breaking. It also has only one rubber seal and no draught excluder.
The fitter says it is correct, any thoughts?
