Our story

For more than three decades, Joseph Sembrat has conserved objects and places of cultural significance — guided by one conviction: a historic object's value lives in its original material, and that material deserves expert, patient care.

He co-founded Conservation Solutions, Inc. (CSI) — recognized for work on national monuments, public sculpture, and the artifacts of the R.M.S. Titanic — which became part of EverGreene Architectural Arts in 2018, where he served as Principal Conservator. Preservation Solutions carries that work forward, partnering with owners, institutions, and public stewards to assess, plan, and treat each piece with care that honors its history and secures it for generations to come.

Joseph Sembrat

President & Principal Conservator

Joseph Sembrat is the founder and Principal Conservator of Preservation Solutions, with more than three decades conserving some of North America's most significant cultural heritage — from the masonry and sculpture of Parliament Hill's West Block and Canada's National War Memorial to monuments, glass mosaics, bronzes, and historic artifacts. A Fellow of the American Institute for Conservation and holder of a Master of Science in Historic Preservation, he works fluently across stone, metal, mosaic, wood, and mixed-media, leading complex projects from first assessment through final treatment.

His approach is defined by restraint and rigor — careful documentation, analytical testing, and reversible treatments, with deep respect for original fabric at the center of every decision. Over his career he has earned the trust of federal agencies, museums, and municipalities, making the fewest, most considered interventions a piece needs to survive for the next generation.
