Misted Double Glazing
Condensation between the panes means the seal has failed. We replace just the glass unit and leave your frames in place — a fast, affordable fix across Central Scotland.
Find out more →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.
- Most units replaced in under an hour
- 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
