J.M. Glass specialise in the intricate process of preserving, repairing, and enhancing stained glass windows and leaded glazing panels that have deteriorated or suffered damage over time. In addition, we can undertake minor stone and wooden window repairs, and all associated metal work restoration.

Traditional leaded windows are cherished for their craftsmanship and historical significance. With over 15 years experience, Jim has a wealth of knowledge in the restoration of historic windows, and supply of new glazing, casements and steel frames for both existing and new windows.

Jim is experienced in the art of traditional face putty glazing, used in the installation and maintenance of windows with individual panes of glass separated by wooden or metal mullions. This method can be used for both single and double glazing.

We understand the intrinsic value of windows in heritage properties., and are able to undertake the delicate process of installing double glazing directly into stone windows. This innovative approach both retains the character of the building and significantly improves insulation.

In addition to breathing new life into existing panels, Jim undertakes bespoke commissions. We also offer the innovative option of encapsulating stained glass panels within double glazing, allowing the timeless beauty of stained glass to grace any modern home while fully complying with modern-day building regulations.
