What you pay comes down to two things: how many rollers are shot, and whether the track or hinges went with them. Orchards houses cluster around a 1998 build year, newer than the service area's overall median of 1994 and younger than most of the 1980s-90s stock that makes up the bulk of the area. That means the rollers in a lot of Orchards garages are still the original builder-grade steel wheels on steel track - stamped hinges, no sealed bearings, nothing upgraded since the house went up. Steel rollers of that generation wear as a set, not one at a time, so a job that starts as 'one noisy roller' usually ends as a full-set swap once a tech is up on the ladder looking at the other nine. Nylon rollers cost more per unit but run quieter and don't need the track lubricated as often, which matters if the door sits in a garage that doesn't get much airflow. We don't price over the phone without seeing the door - a bent track changes the job, and we won't quote a number we can't stand behind once we're on site.
