Windows for Victorian Properties Edinburgh

2-over-2 Sashes · Tenement Specialists · From £1,495 per window

Victorian Edinburgh — the bulk of Marchmont, Bruntsfield, Polwarth, Newington, Tollcross, Leith, Gorgie and Stockbridge tenements — was built between 1840 and 1901 with characteristic 2-over-2 sash and case windows, larger panes and heavier glazing bars. These windows are usually repairable, often dramatically improved with slim-line glazing and brush-pile draught-proofing, and rarely need outright replacement.

What makes a Victorian sash window different

Victorian sashes are typically 2-over-2 (two large panes per sash separated by a single horizontal meeting rail) or, in earlier or grander properties, 4-over-4. Astragal bars are heavier than Georgian — 25-32mm — and glass is machine-rolled with subtle distortions. Frames are deep softwood boxes with cast-iron weights and brass pulleys. Most Edinburgh Victorian sashes are now 120-160 years old and have had at least one repair cycle.

Repair-first approach

Most Victorian Edinburgh sashes are repairable, even when they look terrible from inside. The four typical faults — snapped cords, seized pulleys, rotten lower rails, sloppy meeting rail — all repair for under £500 per sash and add 30+ years of life. Replacement is only justified when the box pulley stiles are rotten through or the sashes are racked beyond plane. Our survey always quotes repair as the first option.

Slim-line double glazing in Victorian frames

Victorian 2-over-2 sashes are ideal candidates for slim-line glazing because the larger pane size suits modern 14mm argon units. Centre-pane U-value drops from 5.8 to 1.2 W/m2K — equivalent to a modern A-rated window. From the street the sash looks unchanged. From the inside, condensation stops, noise drops by 8-12 dB and heat loss through the window halves. £445-£545 per sash retrofit.

Brush-pile draught-proofing

The single biggest comfort improvement on a Victorian sash for the lowest cost. Discreet brush-pile gaskets retrofit into the parting bead, staff bead and meeting rail, invisible from the room but cutting air leakage by up to 75%. Stops the rattle in a westerly gale, removes the cold draught at ankle level, and pays back in heating bills inside two winters. £245 per pair of sashes.

Frequently asked questions

How much does Victorian sash restoration cost in Edinburgh?
Typical pair of 2-over-2 Victorian sashes restored: £895-£1,295 fixed, including full strip, timber splicing, cord renewal, glass cleaning, putty re-bedding, three-coat linseed paint. Slim-line double glazing adds £350 per sash.
Are Victorian sashes worth repairing or should I replace?
Almost always worth repairing. Repair costs 40-60% less than replacement, retains the original timber and proportions, and adds 30+ years of life. Only when the box pulley stiles are rotten through does replacement become economic.
Can Victorian sashes have double glazing without changing the look?
Yes — slim-line 14mm argon units retrofit into the original 19mm rebate. The sash looks identical from the street; only the centre-pane U-value changes, from 5.8 to 1.2 W/m2K.
Do Victorian sashes need draught-proofing?
Almost always — most lose 25-40% of their air-tightness through worn beads and a sloppy meeting rail. Brush-pile draught-proofing is the cheapest comfort upgrade you can make on a Victorian flat, paying back in heating bills inside two winters.
Will replacement Victorian sashes need planning permission?
In a conservation area, yes — prior approval since May 2024 on principal and side elevations. Like-for-like timber replacement is routinely approved; we handle the paperwork.
Do you work in Marchmont, Bruntsfield and Polwarth?
Yes — most of our Victorian work is in the south-side tenement belt: Marchmont, Bruntsfield, Polwarth, Merchiston, Newington, Tollcross and Dalry. Same-week survey usually available.
