Replace the pane, not the frame
If your double glazing has gone cloudy, misted or has water sitting between the panes, the seal has failed — not the window. In most cases the frame is perfectly sound and only the glass unit needs swapped, at a fraction of the cost of a full replacement window.
- Glass units measured for your existing frames
- Frames left exactly as they are
- A-rated and toughened glass options
- Honest advice — we'll tell you if a full window is the better call
