Our History

Our family run company has grown from a background of specialist restoration and preservation of windows and metalwork on many of the finest ecclesiastical and historic buildings. Recognised as the UK’s leading specialist in this field, Canterbury Cathedral, Windsor Castle, Tower of London, V&A Museum, Harrods were just some of the 3,000 projects we were involved with.

Fifteen years ago our company expanded into the industry of slimline steel windows and in that short time we have grown to become the largest manufacturer of W20 slimline steel doors in the world. This has been achieved by the same determination to be recognised as the leading provider of the highest quality product, by innovative engineering and recognising the importance of service to our clients.

Our clients want and deserve the best; value for money is important but quality is key to our clients.
