Their job is to make the transition smooth (unlike what he did for them) but they certainly will want to reinforce the furniture and have washable paint on the walls in rooms where he has been known to throw food. When Joe and Jill walked to the entrance at the White House on Biden's inauguration they had to wait for someone to answer the door; as he departed Trump had insisted to the staff that they all take the day off. Fortunately some of the staff knew what was up and were ready. Trump also didn't attend Biden's inauguration, as most former presidents have when their successor is sworn in. I'm curious to see if Biden attends (or if Trump makes a fuss and excludes him?) Such a cretin.
