This was a bit of an unusual job. The stained glass windows of this magnificent church in San Mateo, CA were built with zinc rather than lead. The common problem with all these windows was that the soldering joints had given up and there was no way to get a solid bond by re-soldering.
The only solution was to be-build every window with new zinc caming and borders. There was also some mis-matched and/or cracked glass throughout which we replaced.
We removed every stained glass window, boarded up the openings with plywood and transported each window to our studio. In studio, we re-built every window with new zinc, replaced glass as needed and completed other repairs.
