Looking for casement window installation in Londonderry? S&K Glazing has been installing across County Londonderry for over a decade. Casement windows — hinged at the side and opening outwards — are the most common window type in modern British homes.
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.
Londonderry's 17th-century walled city, Georgian Bishop Street, and Victorian Waterside generate heritage-led glazing demand across BT47-BT48. Listed-building consents and timber sash restoration form the bulk of our work in this Northern Ireland walled city.
For window-replacement work in Londonderry, the property mix across Northern Ireland 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 BT47 and BT48 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.
