About the service

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.

Sash Window Replacement · Luton

Working in Luton

Luton Airport flight paths affect LU postcodes across the town — aircraft noise plus M1 motorway noise drives heavy demand for our acoustic glazing. We work across both residential and commercial premises throughout Luton and surrounding South Bedfordshire.

For heritage and listed-property work in Luton, planning constraints frequently dictate the spec — we work within Bedfordshire 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 in M1 postcodes. We prepare the heritage statement and Building Regulations submission alongside our quote where it's needed for East conservation areas.

Our process

How we deliver in Luton

01

Heritage survey

We measure the original sash, photograph architectural details (horns, beading profiles, glazing bar widths) and confirm conservation status with your local authority where applicable.

02

Bespoke manufacture

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.

03

Sash-by-sash installation

Installation works elevation by elevation, typically 1-2 sashes per day. We retain original architraves and reveal mouldings wherever possible.

FAQs

Common questions

Yes — modern replacement sashes use double or triple glazing with warm-edge spacers, draught-stripping, and insulating timber frames. Whole-window U-values from 1.3 W/m²K are achievable while keeping authentic appearance.
Inside a Conservation Area or for Listed Buildings, yes — you'll need Listed Building Consent or sometimes planning permission. We handle the application drawings and specifications. For most non-listed homes, replacement falls under permitted development.
Sometimes — slim-profile heritage uPVC sashes with authentic glazing bars and horns are accepted in many (not all) conservation areas. We check with your local conservation officer before quoting.
