Window Repairs

Window 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.

Common window problems we fix

  • Misted or "blown" double glazing — condensation trapped between the panes means the sealed unit has failed and needs swapping for a new one.
  • A window that drops or won't shut — usually worn hinges.
  • A stiff or jammed hinge — hinges wear out over time and stop opening smoothly.
  • A broken lock or handle — the window won't secure properly.
  • Draughts — worn seals or a sash that's dropped out of line.
  • Cracked or broken glass — single or double-glazed panes replaced.

What it typically costs

Can you fix it yourself?

Some window jobs are DIY-friendly:

  • Cleaning and lubricating tracks and hinges often frees a stiff window.
  • Tightening a loose handle is a quick screwdriver job.

But a couple of jobs genuinely can't be done at home:

  • A failed sealed unit can't be DIY-fixed — the glass is factory-sealed and needs a glazier to swap it.
  • Safety glass and any window you can't reach safely should be left to a professional.

When to call a professional

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.
