Video walkthroughs are faster and need no appointment, so they suit most local and mid-size moves. In-home surveys still make sense for very large or complex jobs. Phone estimates are the quickest of all, but the least reliable.
In-home surveys suit large homes, specialty items, commercial moves and high-value long-distance moves. Video walkthroughs win for local and mid-size moves, after-hours leads, busy season and out-of-area customers. A practical approach is video by default and in-home surveys for the exceptions.
