Services
Windows
Our uPVC windows combine German engineering with UK manufacturing to meet Document L regulations. Available in casement, sliding sash, and flush sash styles, they feature multi-chamber systems for A+ energy ratings. Thermal insulation reduces heating bills by minimising heat loss while weathertight seals eliminate draughts. Customisable in white, golden oak, and rosewood finishes with optional RAL colours.
Composite Doors
Thermally efficient composite doors have solid cores and 70mm steel-reinforced frames. They exceed security standards with multi-point locking systems and Secure by Design certification. Available in woodgrain and white finishes, these low-maintenance doors resist weathering. Optional aluminium thresholds accommodate wheelchair access without compromising aesthetics.
Conservatories
Tailor-made conservatories in lean-to, Georgian, Edwardian, and gable styles enhance property value. Factory-assembled roofs ensure precise fitting, while Pilkington glass options improve thermal efficiency. Designs incorporate seasonal light changes and stained glass features. Full-service installation includes planning, surveying, and minimal-disruption fitting for year-round usability.
Roofline Products
BBA-approved uPVC soffits and fascias protect against weather damage with 10-year material guarantees.

Complete roofline overhauls include repairs to rafters and bargeboards, ensuring long-term structural integrity and aesthetic appeal.

Aluminium and uPVC bi-fold doors create seamless indoor-outdoor spaces with slim profiles and 7m maximum width. Their stacking mechanism maximises opening space while maintaining security.
