Services
Conservatories
We design and construct bespoke conservatories that create additional living space while maximising natural light. Our options include Edwardian, Victorian, lean-to, and gable-ended styles, all featuring energy-efficient glazing and durable UPVC frames. Each installation includes a ten-year guarantee against fading or warping.
Home Extensions
From single-storey kitchen extensions to multi-room orangeries, we deliver custom-built home extensions across Merseyside. Our services include full project management, planning permission assistance, and integration of energy-efficient materials. Projects typically cost between 20,000-70,000 depending on complexity.
UPVC Windows
Our made-to-measure UPVC windows feature fusion-welded joints and multi-chamber sections for superior insulation. Available in casement, sash, and tilt-and-turn styles, they incorporate dual compression seals to prevent draughts and come with A++ energy ratings.
Composite Doors
We install Rockdoor composite doors with GRP skins and reinforced aluminium frames. These doors offer enhanced security through multi-point locking systems while maintaining thermal efficiency. Available in various colours and finishes with optional glass panels.
Bifold Doors
Our thermally efficient bifold doors create seamless transitions between indoor and outdoor spaces. Available in 2-7 panel configurations up to 6m wide, they feature low-threshold tracks and weather-resistant seals. Ideal for modernising kitchens and living areas.
