We come out from Athens, about 18 miles, to handle the install. A single-door replacement on a home built in the last fifteen or so years usually goes faster than an older job because the opening is already framed to current standard sizes - no shimming a frame built before anyone agreed on dimensions. A double door with a new opener takes longer than a door-only swap. We don't quote a fixed number of hours here because every opening is different once we're actually measuring it, but we will tell you on the day, before the job starts, roughly how long you'll be without a door. If parts need to be special-ordered - certain insulated panel styles aren't on the truck - that adds lead time you should plan around before you book a date.
