Specialty Contracting

John Canning Specialty Contracting Services

Specialty Contracting is the catchall phrase for projects requiring skill, innovation, and precision in handling the manipulation, removal, or reinstallation of historic architectural artwork and plaster, and the design, planning, and coordination of trades for restoration and new period design/build projects.

John Canning & Co. has built a reputation for innovation in solving difficult design and restoration problems. We combine our knowledge of traditional methods and materials of the past and evaluate emerging technologies of the future that, when combined, can reduce risk when mitigating complex historic interiors and artwork restoration. We’ve developed unique approaches for exterior stone repair and restoration, plaster reattachment and stabilization, and are known for project management, scheduling, and engineering complex scaffold systems that protect the public and provide access for all trades when buildings must remain operational during restoration.
