Summary = Conservation and restoration works to St Lawrence Jewry, London, This project marks the largest phase of work to the building since the reconstruction by Cecil Brown in the 1950's.

Location = London

Challenge = The surviving Wren masonry suffers from heavy carbon staining and discoloration along with a pattern of defects

Solution = Under instruction from The City of London Corporation, Bakers recently started a large restoration project at St Lawrence Jewry, which stands in the yard of the Guildhall. The 18 month project is designed to return the Church to a sound state of repair and safeguard it for future generations.

St Lawrence Jewry, the official church of the Lord Mayor of the City of London, was first built in 1136 in the east end of London - the old Jewish quarter. It was rebuilt in 1677 by Christopher Wren after it was destroyed in the Great Fire of London, and reconstructed by Cecil Brown in 1957 after it was badly damaged in the Second World War.

Conservation and Restoration of St Lawrence Jewry, London

This project marks the largest phase of work to the building since the reconstruction by Cecil Brown in the 1950's. Many of the finishes to the roofs, gutters, cupola and spire date from then and are therefore towards the end of their service life, evidenced by the water ingress that has been an increasing problem in recent years. The surviving Wren masonry suffers from heavy carbon staining and discoloration along with a pattern of defects known as "corrosion jacking", caused by concealed iron cramps rusting, expanding and subsequently splitting and cracking the stonework.

Conservation and Restoration works

The Church will remain open during phase one of the project. Phase one works will involve the cleaning and repair of the masonry elevations, tower and carved stonework; structural work, re-roofing and thermal upgrading of the lead covered Nave; re-roofing of the Commonwealth Chapel, Vicarage apartment and to the south-west of the tower; repairs to the timber framed, lead-clad cupola and spire; replacement of lead gutters and downpipes; overhaul, cleaning and repair of all stained and plain glass windows; replacement of lightning protection; and the repair and structural strengthening of decorative fibrous plaster ceilings. Phase two which is due to start next year will involve all internal works.
