A contractor is a person or company hired to perform specific tasks or projects, often in construction or renovation. They manage the work, coordinate with subcontractors, and ensure that the project meets the agreed-upon standards and timelines. Contractors can work on residential, commercial, or industrial projects. There are different types of contractors, including general contractors, who oversee entire projects, and specialized contractors, who focus on specific trades like plumbing or electrical work. Contractors typically enter into a formal agreement or contract with their clients, outlining the scope of work, costs, and deadlines.
