Composite Doors
Our 44mm composite doors combine GRP finishes with stainless steel hardware for unmatched durability. Certified energy-rated and hurricane-tested, they resist extreme weather while enhancing home security through ERA Vectis locking systems. Each door includes a break-in guarantee for complete peace of mind.
Conservatory Installations
From sunrooms to orangeries, we create bespoke conservatories using thermally efficient materials. Our full-service approach covers design, planning compliance, and installation, with repair options available for existing structures. All installations meet FENSA building regulations.
Double Glazing Repairs
We address broken seals, damaged frames, and faulty mechanisms in double-glazed units. Our technicians restore energy efficiency and security while extending the lifespan of existing installations, avoiding unnecessary replacements.
Secondary Double Glazing
Ideal for listed buildings, our retrofit secondary glazing improves insulation without altering original windows. This solution reduces noise pollution by up to 70% while maintaining historical integrity and compliance with conservation area guidelines.
Porches
Custom-built porches enhance property aesthetics and security. Available in traditional or modern designs, our installations feature thermally broken aluminium frames and toughened glass for year-round durability and improved energy efficiency.
