The duration it takes for a contractor to provide an estimate can vary depending on multiple factors, including project complexity and contractor availability. In general, however, a fair estimate should take anywhere from a few days to about two weeks. During this time frame, contractors can assess the project requirements thoroughly while considering all necessary components like material quantities, permits needed, subcontractor requirements if applicable, and any site visits required for accurate measurements or evaluations. A reliable contractor will strive to provide an estimate within a reasonable period without sacrificing accuracy in order to ensure both parties have clarity regarding budget expectations before starting any work.
