John Canning & Co. provided architectural conservation treatment services at Yale’s Schwarzman Center. The team restored the ornamental plaster, masonry, metal, and wood, and cleaned and repaired any areas of damage or deterioration. Affected areas were test cleaned using multiple methods to determine the best approach. Based on these results, a treatment plan was developed and carried out by Canning to restore the historic architectural features and return the space to its original appearance. Architectural details were highlighted by the conservation cleaning, gilding, decorative finishes, and overall repair.
