There is no responsible universal timeline for stained glass restoration. A single accessible panel and a multi-window church program involve different planning, approvals, material sourcing and installation conditions.
Before studio work begins
Project review, site access, documentation, measurements and scope approval all occur before removal. Equipment, temporary protection and coordination with building schedules may also be required.
What affects studio time
Panel size, number of pieces, condition of the lead, cleaning needs, painted glass, replacement matching, structural reinforcement and curing or finishing steps influence duration.
Why phases can help
For a building with many windows, a phased plan can reduce disruption and align work with funding. Priorities should be based on condition rather than visual prominence alone.
