Historic Restoration and Preservation Services

Contracting Services for all stages of historic restoration and conservation projects.


As a specialty architectural arts contractor, 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.

We provide contracting services for all stages of historic restoration and conservation projects from consulting, pre-construction, project management, construction, and new design.  We also assist with emergency relief and disaster assessments of historic finishes, murals/artwork and decorative elements when the need arises.
