Carpentry is a skilled trade in which the contractor's primary work he performs is the cutting, shaping, and installation of building materials during the construction and installation of kitchens, timber frames, cabinet making, concrete formwork, etc. Traditionally carpentry contractors worked with natural wood and did rougher work such as framing, but today many other materials are also used and sometimes carpentry contractors now do the finer trades of cabinetmaking and furniture building.
