Several types of carpenters are involved in the process of building structures such as homes, offices, factories, or other dwellings. One such professional is the trim carpenter, who is generally responsible for the last phases of construction that involve finishing touches such as installing trim, making furniture, finishing walls, constructing railings, and building various components that make the space more attractive, usable, or otherwise livable. A trim carpenter may or may not work on site at a project; many of the items he or she will make will require large, bulky tools that cannot be transported, so much of his or her time will be spent in a workshop.
One of the specialties of the trim carpenter is, unsurprisingly, installing trim. This includes baseboards, molding, door trim, and other finishing accents in a home. The process of installing such trim can be tedious, and the trim carpenter will need a keen eye for detail, an ability to take precise measurements, make measurements by eye, and operate various tools to create clean cuts and attractive fittings. In this case, the trim carpenter will work onsite with tools such as chop saws, mitre saws, nail guns, hammers, and sanding units such as palm sanders.
In some cases, the trim carpenter may also be required to install cabinets and window casings. The cabinets may or may not have been built by the carpenter himself, but he or she will be responsible for their proper installation and, if necessary, adaptation to a space. Window casings are structures that ensure a window fits snugly and properly into a space; this job is important not only for aesthetics, but also for efficiency. Heat can be lost through the window casings if they are not built correctly, which can lead to higher heating costs in the winter. Conversely, cool air can be lost through the casings, meaning cooling costs in the summer may be higher.
Sometimes a trim carpenter will work in a woodworking shop to create attractive accents for a home. Mantelpieces, railings, or even pieces of furniture can be fabricated for a space without the carpenter ever even visiting the space. He or she may need to work with blueprints or plans, which means this type of carpenter must have strong math skills and an ability to read complex building plans or schematics. Trim carpenters are likely to work with complex machinery such as computer numeric control (CNC) machines that operate off computer software.
