Stained glass businesses design, make, repair and restore decorative glasswork for homes, churches, public buildings and commercial premises. Work may include traditional leaded windows, painted or kiln-fired designs, coloured glass panels, door inserts, screens and smaller decorative pieces. Customers may ask for a new design made to measure, or for a replacement panel to match existing glass and architectural features. Services commonly include measuring and fitting, cutting and assembling glass, leading or copper-foiling panels, and carrying out repairs to cracked glass, damaged leadwork or loose frames. Restoration may involve documenting and carefully dismantling a panel, cleaning or replacing glass, strengthening the structure and reinstalling it. Some businesses also provide advice on protecting historic stained glass, make replicas from existing designs, or teach practical stained-glass techniques through workshops.
