- Non-invasive cleaning of the polychrome areas.
- Repairs to the statues with lime mortar to prevent water from pooling around the stonework and, where possible, halt further decay. To prevent the mortar from drying out too quickly and failing, cotton wool was used around these repair sites.
- Application of a sheltercoat to protect the image screen from the weather.
The work was carried out by the Cathedral’s own stonemasons, supported by The Prince of Wales who made a donation through The Prince of Wales’ Charitable Foundation.
