A straight swap on a door that's structurally sound, in a home with existing 120V wiring and code-compliant sensor brackets, is a same-visit job: old unit down, new rail and motor up, travel and force set, sensors re-aimed and tested. Where it runs longer is when the existing bracket predates current sensor-height code, when the garage has a finished ceiling that needs a jackshaft or low-headroom unit instead of a standard rail, or when the circuit itself needs attention before we'll put a new motor on it. We'll walk the garage, tell you which of those applies, and quote before anything comes off the ceiling. We travel to Summerfield from our Greensboro base, about 8 miles out, so scheduling runs on the same calendar as any other stop on that route rather than a dedicated local slot.
