State of the art production

Our new manufacturing facility combines technology with craftsmanship. CNC controlled machining enables perfect, precise processing of all of our aluminium profiles and plates. We have the latest kit with specifically designed tooling for our doors. With efficient calculation software and storage solutions, we minimise wastage meaning our doors are not only as eco-friendly as possible but also cost efficient meaning we can pass these cost savings on to you.

Our experienced craftsmen assemble every door by hand to ensure quality and perfection every time.
Because we source as much as we can in the UK, our carbon footprint is minimal in comparison to our competitors that build and buy their doors from Eastern Europe.
