A straight install - same size opening, no header or track rework - runs a predictable chunk of a day once we're on site. Older homes sometimes add time: a 1990s frame can be slightly out of square, or the header isn't built for a heavier insulated door, and we have to shim or reinforce before the new door goes up. We won't know which until we're standing in front of it.
We travel from Buford for every Auburn job - there's no local branch, no truck parked nearby waiting. At 11 miles out, Auburn jobs get scheduled on the same run as Flowery Branch and Oakwood stops, not worked as a one-off trip. That keeps the cost down but it does mean install dates get planned around the route, not booked same-morning. If your opener dies and the door won't move at all, say so when you call - that changes how we prioritize the stop.
