Some of the windows in my house will not close completely unless they get a push from the outside as it is being closed.
The are replacement casement double glazed units, put in about fifteen years ago I think, long before I bought the house.
The faulty ones leave a gap of and inch or so on the hinge side.
As far as I can see there is no adjustment in the hinges - they are fixed to the frame with pop rivets.
I have seen similar hinges on sale from Screwfix and others.
Is it likely mine are worn and replacements would fix the problem, or were they installed wrongly in the first place?
