John Knight Glass Ltd

Let us introduce you to... John Knight of John Knight Glass

John Knight Glass joined the network in 2012 and are now really hitting their stride, supplying Bygone Sash Windows in Heswall, The WirrallMerseyside and the wider Liverpool area.

It’s always nice to deal with John Knight Glass on orders as the Liverpool sense of humour often has our processing team in fits of laughter. In fact the glass units in the Bygone Harmony and Symphony are now known as ‘Superman Glass’ after one of the John Knight team famously asked for 'Kryptonite' rather than Krypton in their double glazed glass units.

John and his wife Barbara, who also assists in running the business, are lovely people and really show a desire, to both succeed with Bygone and to provide a good service to their customers.

From John, Barbara and their son Greg through to Sales Manager Graham Mactaggart or anyone at John Knight Glass, there's always a great attitude and pleasant demeanour when dealing with them, as well as great customer service.
