Scuffed walls and scratched floors are one of the most common casualties of a DIY furniture move. Doorframes, stairwell corners, and tight hallway turns are usually where the damage happens — often from misjudging how much clearance a large piece actually needs.
Simple prep goes a long way: measuring doorways and hallways before moving day, removing door hinges if a piece is close on clearance, and using furniture sliders or moving blankets on flooring that scratches easily.
Experienced movers plan the route before lifting anything, which is often the real difference-maker. Knowing exactly how a couch or dresser needs to be angled through a doorway ahead of time prevents a lot of the trial-and-error that leads to dings and dents.
