How to Fix Stiff or Loose uPVC Window Hinges

A common problem for uPVC windows is that they are either too stiff and hard to open. They are too loose and can blow open in the wind or a breeze. Or, they won’t stay open. These are all very easy problems to resolve in a few minutes with a screwdriver.


uPVC casement windows have what are known as friction stays on the hinges. These operate by adding friction to make the window stiffer to open or the opposite, less friction, making it easier to open.


To fix a stiff or loose window, simply turn the screw the right way to adjust the friction stay on the window hinge.
