The stonework externally required attention and internally works were required to make it suitable for visitors to the Tower.

The complete restoration of the tower and the building of a new visitors Heritage Centre was undertaken with a £2 million grant from the Lottery Fund.

The works undertaken by SRS included the following:

• Cleaning of the Portland stone with the DOFF High Temperature Steam System.
• Cutting out and replacement of defective Portland stone.
• Repair of fractures and in-situ restoration works.
• Raking out and repointing of defective joints.
• Repair of the ground floor stucco render and repainting.
• Internal brickwork repairs.
• The supply and installation of Jura Cream cladding on a Generix system to the Heritage Centre.
