Just bought a property where a double glazing pane in the living room needs replacing. TBH, the whole window frame and all the panes could do with replacing, as the frame is an ugly white uPVC. But there's alot of window and alot of frame, so can't just afford at the moment to replace. So I'm currently looking to just replace the double glazing pane. Does anyone have any recommendations on how to go about? Call a local DB company? Or just measure, order online, and install myself? And how to measure? And what kind of costs am I looking at? The pane itself measures approximately 67.5cm wide and 83.5cm tall. Not quite sure how thick the panel is though... Any advice?
