Services
Double Glazing
Double glazing enhances energy efficiency and noise reduction for homes. Our installations use A+14-rated glass with multi-point locking systems for security. Ideal for London and East Sussex properties near busy areas or coastal regions, they provide thermal insulation and lower energy bills.
Composite Doors
Composite doors combine durability and aesthetics with reinforced frames and weather-resistant materials. Available in UPVC, aluminium, or wood finishes, they offer enhanced security features including multi-locking mechanisms and child-safe restrictors.
Conservatories
Custom-built conservatories extend living spaces using high-quality glass and frames. Designed to match existing architecture, they feature energy-efficient glazing and durable materials, ensuring year-round usability and increased property value.
Sliding Sash Windows
Sliding sash windows blend classic design with modern functionality. Fitted with child restrictors and deep bottom rails, they are available in UPVC or wood, offering smooth operation and improved thermal performance for period or contemporary homes.
Casement Windows
Casement windows provide optimal ventilation and natural light. Available in flush or arched designs, they are crafted from UPVC, aluminium, or wood, with weather seals to prevent draughts and enhance energy efficiency.
