I called the company hoping for a same day appointment so technician responded by being at my house in the afteroon. They arrived and started working very efficiently with one staff doing the removal of the old gear and sprocket assembly and its replacement while the other loosening the chain. Ryan lubricated both garage doors and his colleague reset the torque and speed of the machine to ensure optimal working conditions. Now the door works like a charm. Reasonable pricing among other competitors. Courteous and efficient service!
