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.
