John Canning & Co. uses not only its knowledge and experience but also state-of-the-art technology to repair structural problems in fragile historic buildings.  As one of the few authorized installers for HPCS (Historic Plaster Conservation Services) we have access to a suite of products to use as additional tools on consolidation and fragile plaster projects.  John Canning & Co. implements the advanced technology of HPCS to save old plaster by addressing the problem at its root- where the plaster meets its substrate.
