Double Glazing: Repair or Replace? (Costs Compared)
Repair or replace your double glazing? When a £70 sealed unit swap beats a £500 window — costs compared, and honest advice on which…
Read the guideWindow won't shut, misted, or the lock's broken? We repair hinges, locks, handles and sealed units. Honest advice, then a fixed quote.
A window that won't shut, has gone misty, or won't lock is more than a nuisance — it's cold air, a security worry and a higher energy bill. The good news is that most window faults are repairable, and repairing is nearly always cheaper than replacing the whole window.
Prices are typical, not a quote — we confirm the fixed price before any work.
| Fix | Typical price |
|---|---|
| Misted double-glazed unit (per unit) | £55–£145 |
| Window hinge pair | from £75–£145 |
| uPVC lock or handle | from £75 (adjust) / £85 (handle) / £115 (mechanism) |
| Full window replacement | £350–£900 |

Call us if the window won't shut, won't lock, is misted between the panes, or you can't reach it safely. We'll tell you plainly whether it's a simple fix or a full replacement — and we'll only ever suggest replacing when repair isn't worth it.
Call our team or request a callback and tell us what the window's doing.
