Hi there, I need help - I am having trouble with a new UPVC door that wasn't fitted by the supplier!
The door is now kite shaped rather than rectangular and the window in the top pane no longer opens.
The builders accept that the frame is not vertical - top and bottom are horizontal but the sides lean very slightly - they say that the tolerance allowed by adjustable hinges means that this slight variation from vertical does not matter.
The door did fit perfectly initially and showed no evidence of 'leaning' on the side of the lock.
The supplier says that he will take no responsibilty for the distortion of the door as it is the result of the frame not being true.
The door is not a typical size and is 150 cms wide though much shorter than the average door, so I am concerned about the extra strain the width is putting on the hinges.
The top hinge is fully extended and has distorted.
I think that the door should have enough structural integrity to stay rectangular even with the frame not being true.
Is there a recognised tolerance that the frame can be out by??
