Materials Conservation Co., LLC

Materials Conservation Co., LLC recognizes that no two conservation strategies are identical; each must respond to the particu¬lar challenges of location, material, condition and environment. As such, we aim to design and implement conservation programs that meet the specific needs of each project. Materials Conservation respects traditional craftsmanship and original intent and endeavors to conduct repairs that are mechanically, historically, and aesthetically sensitive. At the same time, Materials Conservation aims to implement the most effective yet least aggressive conservation practices possible. This includes using methods and materials that do not have an adverse effect on historic materials, retaining as much original material as possible, and adhering to the precept of re-treatability. We are dedicated to advancing the field of preservation and architectural conservation through the testing and research of new materials. Materials Conservation adheres to both the Secretary of Interior’s Standards for the Treatment of Historic Properties and the American Institute for Conservation of Historic and Artistic Works’ Code of Ethics and Guidelines for Practice.
