We run this job out from Frisco, about 15 miles from Highland Village, so we build the drive into the visit rather than treating it as an add-on. There's no separate branch or depot here - one truck, one trip, and the roller work gets done in that same stop along with any track or bracket check that comes with it.
Because it's a single-service call, booking is simple: tell us whether it's one door or two, whether the noise is constant or only on the first few inches of travel (that split usually tells us if it's the rollers or something further up the track), and we'll get a truck out. We don't carry a stock of every roller size on every visit for every job type, so if your door takes an odd stem length or an unusually wide track, that can mean a short parts wait rather than a same-visit fix. Better to say that up front than to promise a fix we can't finish in one stop.
