Looking for composite doors in Londonderry? S&K Glazing has been installing across County Londonderry for over a decade. Composite doors combine a solid timber core, GRP outer skin and high-density polyurethane foam insulation — making them stronger, more secure and more energy-efficient than any single-material door.

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 doors and glass extensions in Londonderry, residential property style typically drives the design brief across Northern Ireland — whether that's contemporary aluminium bifolds spanning a garden-facing rear elevation, slim-frame sliding doors that maximise glass area on a modern extension, or heritage French doors fitted to a period façade. Most commonly we're working across BT47 and BT48 postcodes. Typical lead time from survey to install: 4-6 weeks for standard configurations, 8-10 weeks for bespoke or large-span builds.
