UPVC Windows
Our A+ energy-rated UPVC windows combine modern insulation technology with classic aesthetics. Each installation features multi-point locking systems and draft-free designs, reducing energy bills while enhancing security. Available in 16 standard colours with optional Georgian bars or obscure glass, these windows suit both traditional and contemporary properties. Our factory-trained installers complete most window replacements within 1-2 days, with minimal disruption to household routines.
Conservatories
Tailored conservatory solutions transform living spaces with year-round usability. Our designs incorporate thermally efficient warm roof systems that maintain comfortable temperatures. Available in Victorian, Edwardian, and lean-to styles, each structure uses low-iron glass for maximum clarity. The 28mm double-glazed units reduce external noise by 35dB, creating peaceful indoor environments. Installation typically completes within 3-4 weeks from initial survey.
Home Extensions
Bespoke home extensions maximise property potential through innovative design. Our HUP! system combines steel frames with insulated panels for rapid installation - typically completing 3m x 3.5m projects in 6-8 weeks. Full electrical and plumbing integration available, with options for underfloor heating and smart home automation. Each extension includes full building regulation compliance certification.
Roof Systems
Warm roof conversions transform conservatories into functional living spaces. The multi-layer construction achieves U-values below 0.18W/mK, exceeding building regulations. Available with integrated LED lighting and ventilation systems, these roofs come with 10-year performance guarantees. Our team typically completes roof replacements within 2-3 days, including full waste removal.
Composite Doors
Security-enhanced composite doors feature 70mm polyurethane cores for superior insulation. Available in 12 standard designs with custom colour matching options, these doors incorporate 3-star Yale locking systems as standard. Our installers complete most door replacements within a single working day, including threshold adjustments and weatherproofing treatments.
