What moves the price
- Extent of the work — replacing cords is quick, a full strip-down and restoration takes days
- Rot in the timber — splicing in new wood to sills and frames adds a large part of the cost
- Draught-proofing — routing in brush seals transforms comfort but adds to the sash window bill
- Glass and putty — reglazing with heritage glass and fresh putty takes careful hand work
- Listed buildings and conservation areas — like-for-like timber and glass may be required for each window
- Size and height — large bay sashes and upper-floor windows need more time and access
Home repair prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical sash window restoration would have cost about £620 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Restore the sash windows in one programme so the specialist sets up only once
- Add draught-proofing while the sash window is apart instead of on a later visit
- Keep sash window paint and putty in good order to avoid costly timber rot
Before you book
- In a listed building, check whether listed building consent is needed before sash window work
- In a conservation area, ask the council whether like-for-like sash window materials are required
- Move furniture and curtains away from each sash window being restored
- Older sash windows may carry lead paint, so ask how the restorer controls dust
Sash Window Restoration cost: questions people ask
£120–£1,200 per window, around £400 typical. New cords cost least; a full restoration of a large, rotten window costs most.
New cords take a few hours. A full restoration takes one or two days per window, sometimes with sashes taken to a workshop.
Repairs are not normally controlled, but a listed building may need consent for anything beyond like-for-like work, and replacing windows in a conservation area can need planning permission. Check with the council first.
For sound timber, often yes. A restored, draught-proofed sash keeps the character of the house and costs less than a new timber sash.
New windows, secondary glazing and redecorating the room are priced separately. In a listed building or conservation area, check with the council before any window is replaced.
