PVC Windows
Our PVC windows combine energy efficiency with security, featuring A+ energy ratings and multi-point locking systems. Available in casement, flush sash, and sliding sash designs, they offer customisation through colour options and woodgrain finishes. Designed to reduce noise and drafts, these windows enhance home comfort while requiring minimal maintenance.
Composite Doors
Composite doors provide ultimate security with multi-point locking systems and durable construction. Available in 32 designs and 31 colours, they offer aesthetic flexibility while maintaining strength. The doors incorporate decorative glazing options and weather-resistant materials, ensuring long-term performance and enhanced kerb appeal for residential properties.
Conservatories
We design and install bespoke conservatories in Victorian, Edwardian, or custom styles. Constructed with reinforced PVC, these extensions offer year-round usability and added property value. Our service includes planning permission assistance and seamless integration of energy-efficient warm roofs for improved thermal performance in existing conservatories.
Flat Roof Repairs
Specialising in EPDM rubber and GRP fiberglass flat roof systems, we provide durable, leak-proof solutions with 20-year guarantees for rubber roofs. Fiberglass options offer 50+ year lifespans with seamless, low-maintenance coverage. Both systems ensure weather resistance while maintaining structural integrity for domestic and commercial properties.
Triple Glazing
Triple glazed windows deliver 40% greater thermal efficiency than A-rated double glazing, reducing energy bills and condensation by up to 80%. The enhanced insulation lowers external noise pollution while maintaining security features. Ideal for properties in noisy areas or those seeking improved thermal comfort throughout the year.
