Sash and case window replacements for Glasgow tenements and West End villas
The Glasgow sandstone tenement window — tall vertical two-over-two sash-and-case, often three or four metres tall — defines the West End, Southside, Dennistoun and Partick streetscapes. Many tenement blocks are B-listed, and Glasgow West and Pollokshields are conservation areas with strict frame rules. Legacy Windows is a quote comparison service that matches you with sash specialists who work with the City Council conservation team and understand slim double-glazing under Listed Building Consent.

Frequently asked questions
Do I need LBC for a Hyndland tenement sash replacement? Almost always yes if the block is B-listed or sits in the Glasgow West Conservation Area. Timber sash-and-case with slim double-glazed units is the typical approved specification. Your installer should submit drawings and glazing details before ordering.
Restore existing sashes or replace them entirely? Draught-sealing sound existing sashes runs £350 to £560 per window and cuts heat loss by around 40%. Full timber sash-and-case replacement with slim units is £1,200 to £2,110 per window. Many tenement owners in Shawlands and Hyndland restore fronts and replace rears in phases.
Do slim units meet Section 6? Slim 11-14mm units achieve around Uw 1.7 W/m²K, slightly above the 1.4 target. Section 6 permits relaxation for listed and conservation buildings when full compliance would harm character — this is routinely granted in Glasgow’s B-listed streets.
