6-over-6 · Crown Glass · LBC Approved · From £1,895 per window
Georgian Edinburgh — the New Town, parts of the Old Town, Stockbridge, Canonmills — was built between 1767 and 1830 with characteristic 6-over-6 sash and case windows, Crown or Cylinder glass, and slim astragal bars. Almost every Georgian property is listed (Cat A or B) or sits in a conservation area, so any window work needs heritage-grade craftsmanship and full Listed Building Consent paperwork. We handle both.
Georgian sashes are taller and narrower than Victorian, divided into six panes per sash by slim astragal bars typically 18-22mm wide. Glass was Crown (hand-blown, with a central bullion) or Cylinder (flat-blown with characteristic ripple). Frames were softwood with hand-cut joints; the box was deep (140-160mm) to house heavy cast-iron weights. Modern replacements that get the proportions wrong — thicker astragals, flat machine glass, shallow boxes — look immediately wrong on a Georgian terrace.
On any Cat A or B listed Georgian property, the council will require restoration rather than replacement except in cases of total structural failure. Our restoration scope: dismantle, splice rotten timber with matched-grain seasoned softwood, renew sash cords in waxed cotton, restore original Crown or Cylinder glass (we hold a stock of period glass for replacement panes), re-bed putty in dark linseed to match original, repaint in a three-coat breathable linseed-oil system. The window comes out factory-fresh and lasts another 60 years.
Modern slim-line argon units 11-14mm deep retrofit into the original 19mm glazing rebate without changing the astragal width or the exterior profile. Centre-pane U-value drops from 5.8 to 1.2 W/m2K. On listed Georgian properties we use Slimlite Heritage or FineO units with a hand-blown outer leaf to retain the Crown-glass ripple; the council usually approves this on a case-by-case basis with a heritage statement.
When the box pulley stiles are rotten through or previous owners have already butchered the window with uPVC, we supply made-to-measure Georgian-pattern sashes in engineered Accoya or laminated European redwood. 18mm astragal bars, ovolo mouldings, brass hardware, factory-finished in your choice of heritage colour. From £1,895 per single window, £2,495 per oversized New Town parlour sash.
Every Georgian project over £4,000 includes full Listed Building Consent paperwork: heritage statement, photographic survey, scale drawings, method statement and submission to Edinburgh City Council Planning. Consent typically takes 8 weeks; we submit during the manufacture window so the consent and the joinery finish together. No separate paperwork fee — it's included in the project price.
Georgian work focuses on New Town (Charlotte Square, George Street, Heriot Row, Queen Street, Great King Street, Cumberland Street, Drummond Place), Old Town (Royal Mile flats above retail), Stockbridge (Ann Street, St Bernard's Crescent), Inverleith and parts of Canonmills. Every job is surveyed by a heritage joiner before quoting — we don't quote sight-unseen on Georgian properties.
Quietest the house has ever been. Bay windows look stunning, and the survey caught a lintel issue two other firms missed.

Door is solid, locks beautifully, and matched the listed-building colour the council insisted on. Faultless fitting.
