Mate of mine has a uPVC bathroom window which opens such that the bottom swings out, so 2 friction hinges - one on each side, and the locking mechanism on the bottom.
When closing the window, the mushrooms of the lock are touching the frame on the left and right, but not the middle. It seems to seal the drafts ok when closed.
The handle and lock is broken as forced too many times. It was really stiff up to it's last successful use
.
The hinges seem sound, there is no wobble/movement evident, however glass is heavy, of course....
I have no issue changing the lock.
Am I likely to find that corrosion / dirt in the sliding part of the mechanism is what's forcing the mushrooms to touch [ maybe forcing has bent that a little too ], or is it more likely that the hinges are 'sagging' somehow.
