A straightforward opener swap, where the mounting and wiring are already sound, usually runs a couple of hours start to finish - mounting the new unit, running the safety sensors, programming remotes, and testing the travel limits.
In Combee Settlement, add time for inspecting what's already there before we touch the new unit. Given the 1971-era build pattern common in this area, we check the header board for rot or softness, confirm the electrical run can handle a modern opener's draw, and look at the track for the kind of wear that shows up after decades of a mismatched motor pulling against an old roller system.
If everything checks out, you're looking at the standard install window. If the header needs reinforcing or the wiring needs updating, that adds a step, and we'll tell you before we start, not after. The truck comes from Lakeland, about three miles out, so travel isn't the variable here - what's behind your garage wall is.
