Looking for sash window replacement in Chelmsford? S&K Glazing has been installing across Essex 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.
Chelmsford's commuter belt sits within easy reach of Stansted's flight path corridor — acoustic glazing is a major service line across CM1-CM3. We also handle the city's modern commercial centre's shopfront refurbishment and large-volume new-build residential re-glazing across the borough.
For heritage and listed-property work in Chelmsford, planning constraints frequently dictate the spec — we work within Essex 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 CM1 and CM3 postcodes. We prepare the heritage statement and Building Regulations submission alongside our quote where it's needed for East 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.
