Window Repair - what to expect

Window repair rather than full replacement makes sense when the frame is sound but a specific fault has appeared - a blown seal, a broken hinge, a misted double-glazed unit, or a mechanism that no longer closes flush. Most repairs are under £250 and done in a single visit; replacement only makes sense once repair costs approach 50% of a new window.

The commonest fault by far is a blown seal - the sealed unit has failed and moisture has got in, showing as permanent misting between the panes. This is a glass-unit replacement, not a frame job: the existing frame stays in place, the failed unit comes out, and a new sealed unit goes in. Around £120-£180 per average unit, done in under an hour once the glass has been made to size.

The next commonest calls are for friction stays (the hinges holding a casement open), gearbox mechanisms, and cill or beading damage from historic water ingress. All are repairable in-situ for well under £200 in most cases. Anything involving a rotting timber cill or a cracked frame usually pushes past the repair-vs-replace threshold.

Typical UK price range for window repair: £89 - £250 installed. Actual figures for your city sit on the city page below.

Before you commit - four things to check

  • Get a written diagnosis before authorising work - some 'blown seal' calls turn out to be internal condensation, which is a ventilation issue, not a glass one.
  • Ask how long the replacement sealed unit is guaranteed for - a decent installer will match the original 10 year seal warranty.
  • For urgent work (broken glass, window that won't lock), most installers charge a call-out fee of £45-£85 on top of the repair.
  • If more than a third of your windows have blown seals, replacement usually beats piecemeal repair - not always, but often.
