windows worth preserving
Belgravia and the surrounding SW1 postcodes represent some of London's finest Georgian and Victorian architecture. Grand stucco-fronted terraces, elegant garden squares and discreet mews houses define an area built to last — and whose original sash windows were made to the same standard.
Around Eaton Square, Chester Square, Belgrave Square and the surrounding streets, original sash windows survive in varying condition — some well maintained, others in need of careful restoration after years of deferred work.
Much of Belgravia sits within Conservation Areas and contains many listed buildings. Original sash windows are integral to the character of these properties — and replacement work may require consent and should be checked before proceeding.
What we do —
done properly
Every service carried out with care and precision
Draught Proofing
Cold draughts and outside noise reduced significantly — without changing the appearance of your windows. We replace staff bead and parting bead with precision brush pile seals and fit a brush seal at the meeting rail.
Sash Cord Replacement
Windows that slam shut or won't stay open — fixed properly. We replace both sash cords on both sides and rebalance both sashes as standard. One visit, done properly.
Glass Replacement
Cracked, broken or misted panes replaced carefully — preserving the original timber frame. Heritage glass available for Conservation Areas throughout Belgravia.
Timber Repair & Repainting
Rotting timber repaired, not replaced wherever possible. The tall Georgian sash windows found throughout Belgravia often suffer from paint build-up at the meeting rail, failing cords and swollen frames — the result of years of deferred maintenance. We work carefully to restore rather than replace, preserving the original timber wherever possible.
Slimline Double Glazing Upgrade
Upgrade single glazing to slimline double glaze units — fitted within the existing frame, preserving the original look entirely. Better insulation, less noise, no change to the character of your property.
Full Sash Replacement
When a window is genuinely beyond saving — we supply and fit heritage timber sash windows made to match the original design of your property. Not uPVC. Timber, made properly.

Working in
Belgravia's
protected streets
Much of Belgravia sits within Conservation Areas administered by the Royal Borough of Kensington and Chelsea and the City of Westminster. There are many listed buildings across Belgravia and the wider SW1 area — and any work affecting their appearance requires careful consideration.
In many cases, draught proofing, cord replacement and careful like-for-like repairs can be carried out without changing the appearance of the window. For listed buildings, flats, replacement work or properties under specific restrictions, we always recommend checking the correct consent requirements before work begins.
