A straight opener swap - old unit out, new belt or chain-drive in, sensors realigned, travel limits set - is a same-visit job once we're on site. We travel to Kuna from Meridian, about 6 miles out, so the job itself doesn't take longer here than it would closer to our shop; it's the same bracket, rail, and wiring work regardless of the drive to get there.
What can add time: if the existing bracket or header mount is undersized for a new, heavier-duty opener, or if the wiring at the wall station is outdated and needs replacing to work with a modern unit. We'll flag that before we start, not after we've already opened the box.
