Services
Aluminium Windows
Our aluminium windows combine slim sightlines with exceptional durability. The thermally efficient frames resist warping and require minimal maintenance while allowing maximum natural light. Ideal for modern and traditional properties, these windows enhance security and reduce energy bills through advanced insulation technology.
Composite Doors
Manufactured from 100% recycled materials, our composite doors offer superior security with multi-point locking systems. Available in various styles and finishes, they provide excellent thermal performance and weather resistance. Each door is customisable with decorative glass options and hardware to match individual preferences.
Glazed Extensions
We design and build modern glass-roofed garden rooms, orangeries, and traditional conservatories. Our extensions maximise natural light while maintaining thermal efficiency. The complete service includes planning permission assistance, structural engineering, and integration with existing property architecture for seamless transitions.
Triple Glazing
Our triple-glazed units feature three panes of glass with argon gas fills for superior thermal efficiency. Reducing heat loss by up to 40% compared to double glazing, these windows lower energy bills while minimising external noise. Ideal for period properties requiring enhanced insulation without compromising aesthetics.
Conservatory Installation
We construct traditional conservatories with uPVC or aluminium frames, offering both modern and heritage designs. Optional WARMroof insulated tile systems provide year-round usability. Each installation includes energy-efficient glazing, secure locking mechanisms, and customisable internal finishes to match client requirements.
