Site clean - up includes coming in behind different subcontractors to clean up their messes and prepping the area for the next subcontractor. For example, once the flooring contractors complete their work, clean - up workers get the property ready for the painters, cabinetry workers or whichever subcontractor is coming in next. Cleaning up on site includes properly disposing of any debris and trash. Often, the clean - up worker will do a walk - through with the contractor to get an idea of exactly what the contractor expects and to receive any special clean - up instructions. The clean - up worker’s will follow up with the contractor to confirm that the clean - up job met expectations.
