A granite installer handles the installation of granite in a house or place of business. Your responsibilities in this career could extend to the installation of other materials such as marble, quartz, or other natural rock or synthetic materials. Property owners often use granite in countertop and kitchen designs. In this job, your duties are to load material into your vehicle, drive to the work site, remove the existing countertop or kitchen accents if necessary, and then install the new granite. At some companies, your job could include preparing the granite for installation at the warehouse before loading it on your vehicle.
