Window & Door Fabricator for Trade & Commercial

Fabricating uPVC and aluminium windows and doors for the trade nationwide


Window and Door Fabricator

GJB is a window and door fabricator which was established in 1990 to make uPVC windows for the trade.  Over the years two separate parts of the business emerged, with GJB Developments supplying the trade and GJB New Build supplying and fitting windows and doors for house builders.

In 2017, Roy Frost bought GJB and put it together with Listers Central Limited and The Big Trade Counter as part of the GJB Holdings Group.  Roy Frost has many years of industry experience after 12 years on the Board of Directors of a large retail company and 5 years as MD of a profile systems company.  Roy’s aim is to be ‘the easiest fabricator to deal with’.

Helping our Customers so they can fit more Windows and Doors

‘Window and door fabricators need to deliver quality products with short lead times, but we also need to help our trade customers’, says Roy Frost.  In order to fulfil this aim, GJB has developed Easy Connect, which is an instant pricing app, so that customers no longer have to work for quotes.  We also provide free Easy Marketing support to our customers.  We do the hard work for you to help you sell more!

Product development and investing in machinery is also key to what we do at GJB.  We constantly update our product range to ensure we fabricate the best range of windows and doors on the market and deliver them to our customers across the UK.  We employ around 120 people at our factory in Essex and have a base in Bedfordshire too where customers can order and collect their windows and doors.

Wide range of Window and Door Brands

Windows and doors fabricated by Listers Central Ltd in Staffordshire are also available to GJB customers.  This means we supply a wide range of brands including The Residence Collection, Solidor, Rayners, Sheerline, Veka Halo as well as our main product lines from Eurocell.

GJB New Build is based in Norwich, and supplies and fits windows and doors fabricated by GJB across the East of England.

A supplier is only as good as the materials they work with. That’s why we’ve handpicked some of the UK construction industry’s most recognisable and respected brands like Residence and Eurocell, applying our decades worth of manufacturing skill to produce the best results.
