Before calculating a price and timescale it is important to see the window/s to assess how much work is required. A visit is best but I can sometimes work from photographs if distance is an issue. Sometimes minor repairs can be carried out in situ, otherwise I remove the window and board up the gap securely.
Back at the studio, the window is dismantled, the glass cleaned, and the old leads sent for recycling. I re-use as much of the original glass as possible and replace badly broken pieces with a good match.
When painted areas need to be replaced, this is done using traditional techniques of kiln-fired painting and staining. The example above shows the process of restoring a vandalised Daniel Cottier window at the Church of the Holy Rude in Stirling.
