Preservation Works Ltd. specializes in historically appropriate masonry restoration and custom plaster. Sustaining our architectural heritage is of the utmost importance to us. Using our knowledge of traditional masonry construction to repair older buildings, we extend this commitment to doing things the traditional (old world) way in contemporary construction interests including decorative lime, gypsum and clay plasters, plaster repair, interior and exterior (stucco), mineral and lime paints, masonry stains and lime washes. These materials have low embodied energy (energy used in manufacturing, transportation and eventual disposal) to create beautiful and unique decorative finishes which are natural, timeless, durable, repairable and nontoxic to all of us.
