A straight swap - same size opening, new door, same track - is typically a single visit. Add a full track replacement, a header repair, or an opener swap and you're looking at more time on site, mostly because of how the jamb and header were framed originally, which varies house to house even within a neighborhood built in the same few years. Houses from 2004 tend to have squarer openings than the 1960s and 70s stock common elsewhere in the territory, which usually means less shimming and fewer surprises once the old door comes down.
What we can't tell you from here is how fast we can get a crew to a specific address on a specific day - that depends on the schedule that week, not on anything about Hampton itself, and we're not going to promise a response time on this page that we can't back up.
