House Builders

Dependable fabrication and supply for builders

Guaranteed to simplify the building process


At GJB Window Systems, we understand that windows and doors are just a small part of what builders and self-builders need to consider in the wider scale of things. Despite this, we remain committed to delivering and supplying the specified product to site when and where required, offering advice on aspects like surveying, installing, and systems choice while helping you specify and order the right products for your project.

Supplying the perfect finishing touch to building projects

When appropriate, we prefer to be involved with a building project’s development as early as possible, letting us account for such factors as frame style, glass options, and other minute details. Whether commercial or residential, PVCu or aluminium, GJB Window Systems has proven the perfect supplier for house builders in the past and are primed to do so again.
