St. Paul Cathedral
The facade restoration of St. Paul’s Cathedral was undertaken to protect the public from falling masonry and to repair the building in time for its 100-year anniversary.
Restoration work was divided into three zones; street level, mid level and high elevation. Stone replacement and dutchman patches were used at lower levels. Matrix was used at the highest levels to patch limestone and repair decorative carvings.
This project received multiple awards from both historic preservation and masonry trade organizations.
