'Double glazing repairs' covers a lot of ground, so it helps to narrow it down. If you can see condensation or a milky haze trapped between the panes, that's a blown sealed unit. If the window is hard to shut or won't lock, it's usually the espagnolette gearbox, hinges or a dropped sash needing adjustment. If a pane is cracked, it's a reglaze. All of those are jobs we do day in, day out.

Replacement salespeople have an obvious incentive to write your windows off. We don't sell new windows, so our answer is always the cheapest sensible fix. Where a frame genuinely is beyond repair we'll tell you straight and you can go to a supplier with an honest second opinion in hand.
