Follow the advice of the moving company that you book the move with. If they are a good quality, expert, best rated moving company, then they know all the things that you should do to ensure that your move is efficient. They may not always immediately offer up this advice, so make sure to ask for it. All moves are different, because of this the ideal preparation for each move will usually be slightly different. Most importantly, plan in advance for a place for the movers to park their truck that is close and easy for them to load. If you are in an apartment or condo, make sure to secure a spot for their truck with building management well in advance and secure private use of any elevator for the specific time of your move. Make sure to confirm the time for the elevator booking with your moving company, building management will not likely hold your private elevator use for the entire day.
