Sash Window Repair Edinburgh

Fixed price · No day rate · Heritage joiners

Sash window repair in Edinburgh covers four faults that come up again and again: snapped cords, seized pulleys, rotten timber on the bottom rail or cill, and rattle from worn parting beads. Heatscape's vetted heritage joiners survey every sash on the window, give you a fixed price per fault, and most flat repairs are done in a single visit with dust contained on site.

We repair Edinburgh sash and case windows to last another century — warmer, quieter, no rattles, no draughts. Call 0800 193 1505 or request a fixed-price survey.

What a proper sash repair looks like

A traditional sash and case window has six wearing parts — the two sashes, the parting bead, the staff bead, the cords and the cast-iron weights in the box. On an Edinburgh tenement that's typically 90 to 140 years old, more than one of these has usually failed by the time you call. A proper survey opens the box, inspects the weights and pulleys, sounds the timber for rot and checks the meeting rail for square — rather than treating the visible symptom alone. You get a written quote that itemises every fault and a fixed price to put each one right.

Sash cord and pulley renewal

A snapped sash cord is the single most common Edinburgh sash repair we see. Cord typically lasts 40 to 60 years; once one breaks, the partner cord and the other sash are usually close to failing too, so we always quote to renew all four cords on a pair of sashes. We use 8mm braided polyester as standard, or waxed cotton on listed properties where the council requires a traditional finish. Pulleys are dismantled, cleaned, re-greased and re-wheeled where the axle is worn.

Rotten timber and splicing

Rot almost always starts at the lower rail of the bottom sash, the cill, or the bottom of the box pulley stiles where rainwater drives in. We never use polyester resin filler on heritage sashes — it traps moisture and accelerates rot beneath. Instead, the affected section is cut out cleanly, a matched-grain seasoned softwood splice is scarfed in with marine-grade adhesive, planed flush and painted with a breathable linseed-oil paint system. A typical bottom-rail splice saves the whole sash from replacement.

Draught-proofing as part of the repair

Adding brush-pile draught seals while the sashes are out is the single best-value upgrade we offer. Routed channels carry siliconised brush pile along the meeting rail, parting beads and bottom rail. You keep the original glass and timber but lose around 80–90% of the draught — and the sashes glide more smoothly than they have in decades. We almost always recommend adding this to a repair visit because the labour is already in the room.

Conservation areas and listed buildings

Repair work that uses original parts and like-for-like materials is permitted-development in most Edinburgh conservation areas and on most Category B and C listed buildings — no consent needed. We confirm the status of your property before quoting, and if the council requires a notice or listed-building application, we handle the paperwork as part of the project. There's no separate planning fee charged to you for a like-for-like repair.

Frequently asked questions

Can rotten timber sash windows be repaired?
Almost always, yes. Heritage joiners cut the rot out and scarf in a matched-grain seasoned softwood splice with marine-grade adhesive. Only when more than 60% of the sash framework has gone do we recommend replacement of that sash — and even then, the other sash in the pair usually saves.
Can sash windows be repaired from inside the flat?
Yes. Cord renewal, pulley overhaul, parting-bead and staff-bead replacement, draught-proofing and most timber splices are all done from inside — no scaffold, no carpet lift, dust contained on site. We only need outside access when the cill or external casing has rot.
How long does a sash window repair take?
A single-sash cord renewal is around 90 minutes. A full pair-of-sashes overhaul with cord renewal, pulley clean and draught-proofing is around half a day. A flat with six sash windows can usually be repaired and draught-proofed in two days.
What's the cheapest way to make a sash window warmer?
Brush-pile draught-proofing while the sashes are out — typically £185 per window — removes around 80–90% of the draught without touching the original glass or timber. It's the highest-value heat-loss upgrade you can do without going to secondary glazing or slim-line double glazing.
Do you work across all Edinburgh postcodes?
Yes — every EH postcode from EH1 to EH17 plus EH28, EH29 and EH30. We also cover Midlothian, East Lothian and West Lothian for sash and case work.
Is Heatscape the joiner, or do you sub-contract?
Heatscape manages the project: we survey your sashes, write a fixed-price scope and the work is carried out by vetted heritage joiners, glaziers and window installers from our partner network. You always know who's working on your property before they arrive.
