A single cable replacement on a door from the late 1980s is usually a contained job - pull the old cable off the drum, check the drum groove for wear, route and tension the new one, and balance test the door before leaving. Where it runs long is when the drum itself has scored from the old cable biting in, or when the opposite side cable is close enough to failure that replacing only one side just means a second visit in a few months. We'd rather tell you that up front than have you call us back in the fall. We don't log response times for this area specifically, since every job here means a trip out from Shoreline, but the work itself doesn't take longer because of distance - it's the same door and the same hardware we work on every day.
