After the construction crew finishes their work, there may, and most likely will be, a certain amount of debris left over. This could include extra nails on the floor, pieces of wood, or even unused cabinetry. Before real cleaning can take place, all of this must be swept, or sometimes shoveled, out into dumpsters. Once this step is complete your new space will start to take shape as an actual livable or workable area.
In this step, it’s also a good idea to wipe down all windows, countertops, and other visible surfaces. This isn’t the final clean, of course, but heavy dust on windows and surfaces you may be touching could make cleaning in phase two more difficult.
