Perfecting Preservation

Even after years of historic restoration of the country’s most prestigious landmarks, we remain awestruck by the majesty and history that these buildings hold, and are most honored to help keep their history alive.

Our principals are professional associates of the American Institute for the Conservation of Historic and Artistic Works (AIC). We are guided by the principle “do no harm” and advance that principle by providing treatments that are reversible and supplying owners with thorough documentation of research, conditions, actions taken, and materials used.


John Canning Co.’s reputation for fine workmanship, high standards, and professionalism has allowed the historic restoration company to choose projects with owners, architects, and other trades interested in doing quality collaborative work.

This team approach has been successful for all involved. Canning Co. continues to grow, and the workforce of talented artisans expands to meet the demand for the company’s unique combination of extraordinary skill, respect for historic integrity, and sound business management.


Our privately owned, family company is continues to be lead by family members with the assistance of accomplished professionals who are committed to upholding the quality, integrity, and accuracy that John Canning Co. is known for.

We believe in education and hire highly skilled and curious artists, artisans, and scholars and teach them how we do things – and why.


It is extremely gratifying to be a part of preserving historic buildings using our expertise in, and passion for architectural arts restoration

It is always humbling to be recognized by our peers and publications for the work we love so much.
