Jim Dossett, Senior Building Enclosure Consultant, RWDI 

During more than 15 years of project work, Jim has earned a reputation for effectively assessing and designing repairs for buildings. He is an expert in the materials and enclosure systems of buildings from the 19th and mid-20th centuries, and has in-depth knowledge about the methods and materials used in the repair and restoration of existing buildings. Our clients benefit from Jim’s holistic approach to older buildings: on every project, he strives to ensure the protection and continued use of the building by considering how its elements and systems – walls, fenestration, roofing, insulation, HVAC and lighting – function together as an integrated whole. In addition to his extensive project experience with building enclosures, Jim’s background includes several years of carpentry work as well as academic training and research in historic preservation.
