Services
UPVC Windows
Our UPVC windows combine security, energy efficiency, and aesthetic appeal. Available in heritage flush sash, casement, tilt & turn, and bay styles, they feature multi-point locking systems and internal glazing beads. Supplied in multiple colours and finishes, these windows reduce heat loss while maintaining durability. Ideal for both period and modern properties across South Wales.
Composite Doors
Our composite doors offer superior strength with GRP skins and insulated foam cores, resisting forced entry and noise. Available in various designs with anti-bump cylinders, they enhance home security while improving thermal efficiency. Customisable colours and finishes ensure seamless integration with property aesthetics, making them a popular choice for homeowners.
Conservatories
We install bespoke conservatories in Victorian, Edwardian, and lean-to styles, using the Pinnacle roof system for year-round usability. Our solutions maximise natural light and living space, with options for roof replacement or full installations. Designed to complement existing architecture, they feature energy-efficient glazing and durable aluminium or UPVC frames.
Cladding
Internal and external cladding solutions enhance home insulation and appearance. Our UPVC panels require no grouting, offering easy maintenance and moisture resistance for bathrooms and kitchens. Durasid exterior cladding mimics wood grain while providing low-maintenance durability, ideal for gables, dormers, and renovation projects across South Wales.
Fascias & Guttering
Durable fascias, soffits, and guttering protect homes from weather damage while enhancing curb appeal. Our colour-matched systems resist discoloration and cracking, with 20-year guarantees. Professional installation ensures proper drainage and longevity, complementing UPVC window and door upgrades for a cohesive exterior finish.
