Experts in conservation.

We’re the largest firm specializing in the preservation of buildings, artifacts, and works of art in the U.S. and have contributed to the restoration and conservation of many of our country’s most significant and iconic masterpieces. From conceptual planning, surveys, and condition assessments to the implementation of conservation treatments and regular maintenance programs, we provide custom solutions for unique and complex interior and exterior heritage preservation projects.

Our conservators bring specialized education, training, and experience with historic materials to each project, leveraging EverGreene’s extensive history of conserving and restoring historic architecture and works of art. Guided by the American Institute for Conservation (AIC), the Secretary of the Interior’s Standards for Historic Preservation, the International Council on Monuments and Sites (ICOMOS), and the International Centre for the Study of the Preservation and Restoration of Cultural Property (ICCROM), our conservation work is implemented at the highest standard under the supervision of our 2 AIC Fellows and 10 Professional Associates.
