Restoration and building maintenance specialist Stone Technical Services (STS) has completed a project for St Paul’s Cathedral.
The Country Durham-based firm worked on the Chapter House, the main office for the cathedral, installing a new lightning protection system on the building originally designed by Sir Christopher Wren in the 17th Century.
Closer to home in the North East, the firm has recently finished restoring the decorative cupolas on Darlington Library, a Grade II-listed building on Crown Street while in North Yorkshire STS’s conservation experts are carrying out surveys and masonry repairs at Ripon Cathedral.
STS managing director Dave Stone said: “Working on a listed building demands an exceptionally high level of skill and expertise. It always requires very specialist work, often by hand, and there can be many pitfalls if the job isn’t done correctly.
“We’re working on some incredibly historic buildings and we always get to know the full history beforehand and work empathetically to ensure no disruption to the aesthetic.”
