Customer called out for a service because the door was sitting crooked, when I got out on site noticed they had two single stall doors on extension springs. During my inspection, I found that one of the extension springs and the cabling were removed from one of the doors which was causing the door to sit on level. These doors being that they are original to the house, the replacement was suggested not only due to the age, but due to the cost of what part replacements needed to be done, measurements were taken a new door estimate was typed up and sent over to the customer.
