Stained Glass and Leaded Light Repair

Stained glass panels and leaded lights are a common feature of older buildings and are often valued by clients due to their historical significance or simply because of their unique and artistic appearance which adds to the character of a building.

If not correctly maintained, leaded lights and stained glass panels can become dirty and damaged over time. Working closely with Stevenson Stained Glass, Fergmann have the means to repair the existing windows, including the installation of replacement glass manufactured to be as close to the original colour and texture as possible, minor or extensive repairs to lead work and cleaning to bring out the original, eye-catching appearance of the windows. Manufacture from scratch is also possible if specifications are provided.

Sometimes the problem with leaded lights and stained glass windows is their thermal performance due to being single glazed. It is possible in some cases to have a stained glass panel encapsulated inside a double glazed unit and returned to its original position with minimal alterations to the existing window. If the stained glass panel or leaded light is too large to be encapsulated, another option would be to install a clear secondary glazed screen internally through which the original piece would still be visible.

  • New sash and case windows, casement windows and deadlights to replicate existing windows or to replicate the style of the original window which would have occupied the opening.
  • Fire rated screens which may be designed to replicate the configuration of surrounding windows as closely as possible.
  • Windows of original design by Fergmann (see West Register Street in projects tab)
  • Secondary glazing screens to improve thermal performance where existing window is a single glazed stained glass window.
  • Fergmann have the means to repair metal windows and we have developed a system for draught proofing them. In some cases it may be possible to introduce double glazing to these windows.

    “We weren’t disappointed”

    “I’ve used this Fergmann’s several times to purchase and install windows to our family home and now garden summer house. I’m a returning customer. Previously, our overall experience was first class. From enquiry, to surveying, to supply and finally installation, was flawless and on time. Tidy, professional workmanship on installation made us return, to which we weren’t let down second time round. Just recently Fergmann’s supplied and installed windows to a newly constructed summers house and again we weren’t disappointed.” – GarryM-1969 on
