Installation gets scheduled around the opening, not the calendar. Once we know the rough size and condition of your current door and frame, we can tell you whether this is a straightforward swap or a frame job that needs more time on site. Older openings - especially on houses from the earlier end of that 1938 to 2013 range - more often need carpentry work before the new door goes up, and that changes how much time we block for the job.
We work across the Columbia service area, including the six named sections of town where most of the 1980s and 90s housing stock sits. If you're closer to Mount Pleasant, Thompson's Station, Lynnville, Lewisburg, Chapel Hill, or Summertown, say so when you call - distance affects how early in the day we can get a crew to you, not whether we'll come.
