A straightforward swap - same mounting point, existing wiring reused - is a half-day job once we're on site. Kings Grant sits about 4 miles from our Wilmington shop, so travel isn't the time sink here; the house itself is. Older headers sometimes need reinforcement before a new opener can hang safely, and if the original unit predates photo-eye sensors, we're adding that wiring from scratch, not just connecting it. Neither of those is rare in this neighborhood given the 1980 build era, so we build in time for it rather than promise a number we can't back up.
