Colonies · Main Door · Tenement Ground Floor · From £1,295 per window
Edinburgh's colony flats — Stockbridge, Abbeyhill, Restalrig, Leith and Hawthornvale — are unusual: two-storey terraces with separate upper and lower flats, each with its own external door. Many sit in conservation areas. Main-door tenement flats share similar quirks. The windows are often smaller than tenement parlour sashes, with mixed casement and sash patterns, and need joiners who recognise the typology before they quote.
Built between 1860 and 1911 by the Edinburgh Co-operative Building Company, colony flats are stone-built terraces of two-storey blocks, with lower flats accessed at street level and upper flats accessed by external stone stairs. Windows are typically a mix of two-over-two sash and case at the front and smaller casement windows to bathrooms and stairs. Many are now in conservation areas (Stockbridge Colonies and Abbeyhill Colonies both designated).
Main-door flats are ground-floor tenement flats with their own street entrance rather than a shared close. Window challenges include security (street-facing ground-floor glass), retained heat (often the coldest flat in the stair due to less neighbour insulation) and access (we can work from outside on a street-facing main door without scaffold). Common upgrades: laminated security glass, slim-line double glazing for warmth, brush-pile draught-proofing.
Stockbridge Colonies, Abbeyhill Colonies and Restalrig conservation areas all require prior approval for replacement windows on principal elevations. Timber, original astragal pattern and matching paint colour are standard requirements. We handle the prior-approval paperwork as part of every quote. Rear elevations (the gardens behind the terraces) usually fall outside the requirement.
Sash cord renewal £185 per sash; brush-pile draught-proofing £245 per pair; slim-line double glazing retrofit £445 per sash; casement window replacement £695-£995; full sash replacement £1,295-£1,695 per window. Most colony flats need a combined scope across 4-8 windows; expect £4,000-£8,500 for a full upgrade.
Main-door and lower colony flats with street-facing glass benefit from laminated security glass — a clear plastic interlayer between two panes that resists impact and stays in place even if shattered. Adds £85-£145 per pane over standard glazing. Insurance discounts often available with proof of installation.
Stockbridge Colonies (Reid Terrace, Hugh Miller Place, Rintoul Place, Bell Place), Abbeyhill Colonies (Maryfield, Albion, Lyne, Moncrieff), Restalrig Colonies, Leith Colonies (Hawthornvale, Trafalgar Street), and main-door tenements across Marchmont, Bruntsfield, Newington and Leith.
Listed-building paperwork sorted for us, original sashes saved, and the front room is no longer a wind tunnel. Brilliant from quote to completion.

Quietest the house has ever been. Bay windows look stunning, and the survey caught a lintel issue two other firms missed.
