The craft — works manual, extract

What a leaded light is

A leaded light is a window made of separate panes, each held in an H-section strip of milled lead called a came. The joints are soldered where the cames cross, and the finished panel is cemented — putty worked under the leaves of the lead — so the window stands weathertight without a bead of sealant anywhere in it.

Leaded lights fail slowly. Lead fatigues, cement dries out, panels bow away from their fixings. A bowed panel is rarely a lost panel: taken back to the bench, it can be opened, rebuilt on its original cutline in new lead, and reinstated with the glass it was born with.

That has been the work of this firm since 1974 — leaded light restoration, stained glass repair and conservation, and new leaded lights, all of it cut and built in our own York workshop.

Glossary — from the works sheet

Came
Milled lead strip, H-shaped in section, that carries each pane. Matched like-for-like in repair.
Crown glass
Glass spun by hand into a disc, giving the swim and bullseye of period windows. Salvaged and held in stock.
Cementing
Putty cement brushed under the leaves of the came, then blacked off. What makes a panel weathertight.
Horseshoe nails
Flat-sided nails that pin the panel to the bench while it is built. They leave no mark on the glass.

The Victorian panel over our door went away in pieces and came back true. The replacement quarries were matched from their own salvaged stock; we cannot tell which panes are new.

E. Marsden Bishophill, York · March 2025

The condition report photographed every panel before a tool was lifted. Our architect called it the clearest survey he had seen.

M. Calvert, churchwarden North Yorkshire · November 2024

Dust sheets down at eight, swept out by half past four, and a note left of exactly what had been done. Method throughout.

J. Pemberton, trust secretary York · June 2025

They argued us out of replacing the glass and repaired it instead. The draught has gone, and the glass is the one the house was built with.
