About Mary
Mary Johnson serves as Research Editor at Home Project Cost Guide, where she oversees the editorial quality, data accuracy, and content structure of all kitchen and bathroom remodeling guides. With 8 years of experience in home design and renovation journalism, Mary brings a unique combination of editorial rigor and industry knowledge to the team. She specializes in breaking down complex remodeling scopes into clear, comparable cost components that help homeowners understand what drives the price of their project. Mary's editorial process emphasizes transparency — every cost range should be traceable to identifiable cost drivers, and every calculator should produce outputs that align with real contractor pricing patterns. She previously wrote for home improvement publications in Los Angeles, covering design trends, contractor selection, and renovation budgeting for West Coast homeowners.
