I have recently noticed that on some on my windows that the double glazing is no longer sitting flush in the frame.
Hopefully this can be seen from the pics. You can see that the frame is bulging in the middle, and has shifted in the corners.
There are no visible cracks in the walls at all, and the only thing that I can see that is wrong is with the metal frame of the dbl glazing
I at at a loss as to why this is happening.
Is anybody able to say what is going on? and if I have a major problem.
Thanks
