uPVC Windows
Our uPVC windows offer exceptional thermal efficiency, security, and durability. Designed with UV-stabilised profiles, they resist discolouration and warping. Ideal for domestic properties seeking cost-effective, low-maintenance solutions with modern aesthetics.
Composite Doors
Composite doors combine a solid timber core with durable outer layers for superior strength and insulation. Available in custom designs, they enhance security and energy efficiency while maintaining traditional or contemporary aesthetics.
Bi-Folding Doors
Bespoke bi-folding doors create seamless indoor-outdoor living spaces. Engineered for stability and ease of use, they feature slim frames and high-performance glazing to maximise natural light and thermal efficiency.
Conservatories
Our conservatories use Guardian Warm Roofs for improved insulation, transforming unused spaces into year-round living areas. Available in modern or traditional styles, they integrate seamlessly with existing properties and include full electrical and plastering works.

Custom-built porches enhance property security and energy efficiency. We offer pitched, gable, or flat roof designs with full installation, including glazing, roofing, and electrical upgrades to meet building regulations.

1st GW replaced two 'blown' double glazed units for us. Really friendly and efficient service at a good price. We will definitely use this company again.

I required the original landing window - of wood & stained glass - to be raised & the stained glass put inside a new uPVC double-glazed window (to create triple glazing). The finished result is superb & I am chuffed that I have kept the stained glass.

Superb. John and Troy fitted my mum's new windows in her retirement flat yesterday and they look great! John and Troy were friendly and courteous throughout and left everything very clean and tidy. We won't hesitate to use 1st Glass again and highly recommend them. Thank you!

Excellent experience from start to finish, from all staff involved. Darren and Bill fitted all our new windows and frames, and 2 doors, very speedily and with absolutely minimal impact to existing decoration, and kept everything as clean as could be hoped for given the work being done. Some minor snags (probably due to long storage of window units at manufacturer) were dealt with very promptly.
