About Us


Janex have been at the heart of the window and door industry in the UK since 1992, it won’t be long until our 30 year anniversary and that is a whole lot of high performance windows and doors experience at your disposal.

Our long serving team have a wealth of experience, and have faced most issues, big and small, that crop up on site. This experience allows us to understand the challenges our clients may face and find solutions to minimise disruption and cost.

Janex work throughout the UK on all sorts of projects.  We have extensive experience in social housing, however, we have also completed large student accommodations, health centres, schools and office accommodations. We have worked successfully with many of the large contractors in the industry and you can see examples of this in our previous projects.

We work closely with many Architects and Small Builders to delivery ‘one-off’ self builds and can offer large sliding doors, bi-fold doors and shaped windows, to compliment everything from the most contemporary large self builds, to the small garden extension.  Whatever the project, large or small, everyone will experience the same quality service from the Janex team.

From Lands End to John O’Groats, we have worked throughout the country, in partnership with our reliable hauliers to deliver quality products, safely and on time, wherever you are.
