Services
Bi-Folding Doors
Our bi-folding doors combine sleek aluminium frames with superior security features, allowing maximum natural light while maintaining thermal efficiency. Available in custom colours and configurations, they seamlessly connect indoor and outdoor spaces. Designed for both modern and traditional properties, these doors offer smooth operation and long-term durability with minimal maintenance requirements.
UPVC Windows
Durable UPVC windows provide excellent insulation and security with low maintenance needs. Available in casement, sash, and vertical slider styles, they feature multi-point locking systems and energy-efficient glazing options. Ideal for modernising older properties or new builds, these windows enhance comfort while reducing energy bills through advanced thermal performance.
Conservatories
Custom-built conservatories create year-round living spaces using thermally efficient aluminium or UPVC frameworks. Featuring insulated roofs, double-glazed units, and optional integral blinds, they blend seamlessly with existing architecture. Available in Victorian, Edwardian, and contemporary designs, these structures add property value while providing versatile additional space.
Double Glazed Units
Made-to-measure double-glazed units improve thermal efficiency and noise reduction. Options include Georgian bars, decorative glass, and security-enhanced laminated panes. Replacing misted or damaged units restores window performance, with energy-efficient coatings available to further reduce heat loss and UV damage to interiors.
Heritage Doors
Crafted timber and composite heritage doors maintain period authenticity while incorporating modern security features. Available with decorative glass options and traditional ironmongery, they enhance listed buildings and conservation area properties. Backed by long-term warranties, these doors combine aesthetic appeal with improved insulation and draught-proofing.
