A cabinet installer fits cupboards into kitchens, bathrooms, closets, garages, pantries, and other spaces. While their primary clientele consists of residential property owners, some commercial tenants hire a cabinet installer to install cupboards in office areas. The duties of a cabinet installer include measuring rooms and spaces to determine the materials needed, building custom and ready-made cabinets, handling the installation of parts, and applying finish such as paint or stain. You need skills with power tools and hand tools to be a cabinet installer.
