Services
Windows
Our UPVC and aluminium windows combine durability with aesthetic appeal, featuring reinforced frames and weather-resistant seals. Available in Georgian bars, diamond lead patterns, or modern designs, they enhance thermal efficiency and security. Each installation includes a 10-year guarantee for lasting performance.
Doors
PVC-U doors with galvanised steel reinforcement and advanced locking systems ensure security and insulation. Options include solid panels, clear glass, or decorative designs. Double seals prevent draughts, while internal insulation reduces heat loss, improving energy efficiency for residential properties.
Conservatories
Custom conservatories blend white or woodgrain finishes with glass or polycarbonate roofs, creating versatile living spaces. Designed to connect homes with gardens, they feature durable materials and energy-efficient glazing. Ideal for extending lifestyle areas with natural light.
Rooflights
Rooflights enhance natural light in kitchens, bathrooms, or extensions. Suitable for flat roofs or new builds, they feature sealed glass units and weatherproof designs. Available in various sizes to complement modern or traditional properties while improving spatial perception.
Fascias
Durable UPVC fascias protect roof edges from weather damage while maintaining a clean exterior finish. Resistant to rot and discolouration, they require no painting and integrate seamlessly with existing guttering systems for long-term functionality and aesthetic appeal.
