Looking for casement window installation in London? S&K Glazing has been installing across Greater London for over a decade. Casement windows — hinged at the side and opening outwards — are the most common window type in modern British homes. For London properties near Heathrow, Gatwick, City, Luton, Stansted, we can specify acoustic-grade glass to reduce aircraft noise alongside thermal performance.
Casement windows — hinged at the side and opening outwards — are the most common window type in modern British homes. They offer excellent ventilation, easy cleaning, and the best thermal seal of any opening window type because compression against the frame creates a continuous draught-proof barrier. S&K Glazing installs casement windows in uPVC, aluminium, and timber across the UK, with double or triple glazing as standard.
London is our largest single market — 33 boroughs, five international airports, the M25 motorway and railway lines crossing every postcode. Our acoustic glazing dominates demand in flight-path postcodes near Heathrow (TW, UB, SW), Gatwick (RH, KT, CR) and City Airport (E16, E14). Plus commercial shopfront work across every high street and Zone 1-2 retail district.
For window-replacement work in London, the property mix across London ranges from period stock through to modern new-build, so we specify the thermal solution per property — A++ rated double-glazed sealed units for standard upgrades (U-value 1.4 W/m²K), A-rated solar-control glazing for south-facing elevations, and triple-glazed argon-filled builds achieving 0.8 W/m²K for owners targeting near-Passivhaus performance. Most commonly we're working across M25, E16 and E14 postcodes.
We measure each aperture, photograph the existing window, discuss your preferred opening configuration (top-hung, side-hung, combinations) and confirm glazing specification.
Within 24 hours we send a fixed-price quote separated by elevation, with multiple glazing options (double, triple, acoustic, low-iron solar glass).
Lead time typically 3-4 weeks. Installation usually completed in 1 day for a typical 3-bedroom home. We protect floors and dispose of all old units.
