Broken Springs Garage Door Specialist

One spring broke but since I was doing three doors he gives me a good price. He removed the springs and told me the bearings need changing. He then told me I should change the wheel, the cables and the brackets at the bottom. I then asked how much all this will cost. He contacted the office and he told me $500, later he said $550. He said for $650 he would replace the rollers. To my surprise he replaced wheels on only two doors, replaced cables and brackets on only one door.
