Looking for sash window replacement in Kensington & Chelsea? S&K Glazing has been installing across Greater London for over a decade. Sliding sash windows are the architectural signature of British period properties — Georgian, Victorian, and Edwardian terraces, townhouses, and cottages.
Sliding sash windows are the architectural signature of British period properties — Georgian, Victorian, and Edwardian terraces, townhouses, and cottages. Original timber sashes often suffer from rot, draughts, rattle, and single-glazed inefficiency. S&K Glazing manufactures and installs replacement sash windows that match the original sightlines, glazing bar layouts, and sash horn profiles, but deliver modern U-values from 1.3 W/m²K and acoustic reductions up to 42dB. Available in engineered timber or slim-profile uPVC for conservation areas where uPVC has been approved.
Kensington and Chelsea's grand Georgian and Victorian houses and stucco terraces demand the highest standards in glazing — bespoke timber sashes, slimline secondary glazing for listed buildings, and discreet acoustic upgrades for Heathrow flight-path properties. We work extensively across SW1, SW3, SW5, SW7 and W8.
For heritage and listed-property work in Kensington & Chelsea, planning constraints frequently dictate the spec — we work within Greater London council's conservation area rules and listed-building consent requirements, using putty-glazed timber sashes, slim-sightline secondary glazing systems that sit invisibly behind original primary glazing, and steel-window restoration for Crittall-style frames. Most commonly we're working across SW1, SW3, SW5 and SW7 postcodes. We prepare the heritage statement and Building Regulations submission alongside our quote where it's needed for London conservation areas.
We measure the original sash, photograph architectural details (horns, beading profiles, glazing bar widths) and confirm conservation status with your local authority where applicable.
Each replacement sash is manufactured to your exact original dimensions and profile. Timber units use engineered redwood or accoya with factory micro-porous paint. uPVC units use slim heritage profiles.
Installation works elevation by elevation, typically 1-2 sashes per day. We retain original architraves and reveal mouldings wherever possible.
