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.
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.
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.
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.
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.
When replacement is unavoidable, we supply made-to-measure 2-over-2 Victorian-pattern sashes in engineered Accoya or laminated European redwood. 28mm astragal bars, period-correct mouldings, brass hardware, factory-finished in heritage colour. Conservation-compliant on every Edinburgh Victorian conservation area. From £1,495 per single sash, £1,895 for oversized parlour windows.
