Stained Glass Restoration - Returning Stained Glass Windows to there original beauty

Re-leading stained glass windows can return them to their original beauty and prevent further glass breakage for another 100 years - making the investment more cost effective than most major building repairs.

The following is a description of Classic Glass Ltd.'s re-leading process:

  • Document existing installation of stained glass windows and surround.        
  • Label all panels and openings.
  • Remove stained glass panels from exterior of framework utilizing scaffolding or lifts.
  • Assess stability, and stabilize if necessary stained glass panels prior to removal.
  • Package stained glass windows in protective packaging for safe transportation to studio.
  • Templates and measurements of openings and arc of frame will be taken at job site to insure proper fit at re-installation.
  • Once at studio, the stained glass windows will be assessed for replacement materials, and materials will be ordered.
  • Stained glass windows will be documented and completely dismantled.
  • Broken glass will be replaced or leaded, depending how it effects the design, to be determined on a case-by-case basis.
  • Mismatched glass (previous replacements) will be replaced.
  • Each individual piece of glass will be cleaned.
  • Stained glass windows will be completely re-leaded using lead came to match original profile.
  • Stained glass windows will be puttied/cemented on both sides as per the specifications with a mixture of linseed oil, calcium carbonate, and blacking.
  • Apply new flat steel re-bar to back (outside) of the stained glass panels.
  • Polish and clean stained glass windows.
  • Package stained glass windows in protective packaging for storage and safe transportation to job site.
  • Re-install panels utilizing scaffolding or lifts.
  • Install rubber shim blocks to align panels as much as possible.
  • Re-glaze stained glass windows into opening.

The process is based on the Stained Glass Association of America standards and guidelines for restoration of stained glass windows.
