York Glaziers Trust undertakes conservation projects on behalf of owners and custodians of stained glass of all periods, in historic buildings from great Cathedrals to the smallest of parish churches, in museums and art galleries and in private collections.Based in a workshop in the centre of the historic city of York, the Trust offers a wide-ranging service, including conservation, repair and protection of medieval stained glass, of enamel painted glass of the 17th century and Georgian era, of Victorian and Edwardian stained glass, of twentieth-century windows and of historic plain glazing. Our staff also provide an unparalleled advisory service.
Modern cleaning techniques not only remove damaging corrosion deposits, but can also improve legibility, brightness and translucency of a window.
Windows can also be endangered by weakening and failure in the structure of the lead net or by failure in the window's support structure. The failure of the waterproofing of the window causes it to leak, damaging glass surfaces and surrounding stonework. The lead net is nonetheless part of the historic fabric of the window, so re-leading should be undertaken only after careful evaluation.
