If you’re trying to budget for sash window repairs in Edinburgh, the honest answer is: it depends entirely on what needs doing. A single cord replacement can cost as little as £80. A full frame restoration with draught proofing and re-glazing on a period sandstone villa can reach £1,400 or more. This guide breaks down the real costs — and what drives them.
Sash Window Repair Cost Summary (Edinburgh, 2025)
| Job Type | Cost Range | Notes |
|---|---|---|
| Single cord replacement | £80 – £150 | Per sash; half day |
| Full cord & weight overhaul | £250 – £450 | Both sashes; one day |
| Draught proofing (per window) | £150 – £280 | 18mm brushpile seal |
| Timber rot section splice | £200 – £600 | Depends on extent |
| Full sash restoration | £600 – £1,400 | Frame, cord, glass, draught seal |
What Affects the Cost?
Three factors drive the final price of any sash window repair in Edinburgh: the extent of damage, access and window size, and the materials required.
Extent of damage. A window with two failed sash cords costs far less to repair than one with rotted sills, failed putty, and seized pulleys. The longer damage is left unaddressed, the more expensive the repair becomes — a £150 cord job neglected for three years can become a £600 timber repair.
Materials. We use pre-stretched waxed cotton sash cord (6mm) and European Redwood (Pinus sylvestris) for frame repairs — the same materials used originally. These cost more than modern alternatives but produce repairs that last decades, not years.
Listed buildings and conservation areas. Working on Category A or B listed properties in Edinburgh’s conservation areas does not increase the cost of repair itself, but may require additional care and documentation. It does not require any planning consent for like-for-like repairs.
Can I Get Multiple Windows Done More Cheaply?
Yes. Most tradespeople — including us — will reduce the per-window rate when working on multiple windows in a single visit. A tenement flat with six sash windows repaired in one visit will cost noticeably less per window than a single one-off job. It also means less disruption to you.
Repair vs Replacement: The Cost Comparison
Replacing a traditional Edinburgh sash window like-for-like costs between £1,500 and £3,500 per window depending on size and specification. Full period-correct replacement of all windows in a four-bedroom Marchmont flat could cost £20,000 or more. Repair almost always costs a fraction of this — and in conservation areas and listed buildings, replacement often requires consent that repair does not.
