uPVC Windows
Our A-rated uPVC windows offer exceptional thermal efficiency, with u-values as low as 0.8W/mK. Designed to reduce energy bills and noise pollution, they enhance security and add value to your property. Manufactured in Great Britain, these durable windows are available in casement, sliding sash, and tilt-and-turn styles to suit both traditional and modern homes.
Composite Doors
Our composite doors combine strength, insulation, and aesthetic appeal. Featuring a galvanised steel core for security, they resist warping and require minimal maintenance. Available in various finishes and styles, including bi-folding and French doors, they improve energy efficiency and provide a secure, stylish entrance to your home.

We design and install bespoke conservatories, including Edwardian, Victorian, and lean-to styles. Using Ultraframe systems and Guardian Warm Roofs, our conservatories offer year-round comfort with superior insulation. Customisable to fit unique spaces, they add living area and natural light while maintaining structural integrity and energy efficiency.

Wouldn't hesitate to recommend Graham and Dave who replaced our secondary glazing. Both were really nice, very professional, have done a cracking job.

We contacted Darren Young to price for a new Composite front door. From advising on products to completion of the work, we were kept fully informed.
