Our reputation
John Williams has acheived full membership status of the Glass and Glazing Federation, an independant body set up under the auspices of the Office of Fair Trading, who maintain a strict code of ethical practice for the industry.
This reassurance means our customers can buy with absolute confidence - a first class product, well constructed and installed.
We not only aim to provide quality products and service, but safety and security are very important features we incorporate into our designs. All our windows and doors are supplied with a purpose-built shoot bolt, 4 point locking mechanism with key locking handles. All glazing is internal so no worries there, the units cannot be removed from the outside. High security friction stays keep the windows in the position you choose, so you can select the degree of ventilation you want, without fuss.
John Williams also supply Ultima E Glass as standard. This revolutionary heat reflective glass actually reflects generated heat back into the room, thus reducing your fuel bills and increasing your comfort. We also offer a wide range of obscure glass units for privacy, and solar control units to help protect your furniture if required.
With a comprehensive range of additional extras, John Williams spoil you for choice! Whether you are looking to maintain or change to a period appearance we have an extensive range of decorative lead finishes to suit your style.
Coloured lead designs are our speciality and with the latest in computer technology we can reproduce virtually any design you wish. The Heritage Collection from John Williams combines the traditional with the benefits of high technology.
Choose the outstanding value and quality of John Williams, you simply couldn't make a better choice.
