Conservatories
Our bespoke conservatories combine modern insulation technology with classic design elements to create year-round usable spaces. Available in Victorian, Edwardian, lean-to, and gable-end styles, each structure features thermally efficient glazing and decorative cornice options. Customers can choose from multiple roof styles and internal pelmet configurations to match their property's aesthetic while benefiting from 25% faster installation times compared to traditional extensions.
Garden Rooms
Custom-built garden rooms provide versatile living spaces with superior thermal efficiency and minimal disruption to main residences. Constructed using insulated concrete foundations and independently wired for utilities, these structures maintain comfortable temperatures year-round. Available with bi-fold doors, triple-glazed windows, and bespoke interior layouts, they serve equally well as home gyms, studios, or guest accommodations while retaining 90% of their value during property sales.
Double Glazing Repairs
We offer comprehensive double glazing maintenance including sealed unit replacement, lock upgrades, and draught-proofing services. Our technicians carry stock parts for most major window brands and can complete emergency glass replacements within 48 hours. All repair work maintains original manufacturer warranties and improves thermal efficiency by up to 30% through modern low-E glass upgrades.
Aluminium Windows
Slim-profile aluminium windows provide enhanced security and durability while allowing maximum natural light entry. Available in powder-coated RAL finishes, these windows feature multi-point locking systems and argon gas-filled units achieving U-values as low as 1.2W/mK. Their corrosion-resistant frames require no painting and maintain structural integrity for over 35 years in coastal environments.
Conservatory Roofs
Thermally efficient roof systems transform outdated conservatories into comfortable living spaces. Options include tiled roofs with integrated skylights, glass roofs with solar control glazing, and hybrid lantern designs. All replacements meet current building regulations and reduce heat loss by 60% compared to original polycarbonate roofs while maintaining natural light levels through optimised glazing ratios.

Can garden rooms be installed in stages?

What security features do your doors include?
