A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.
Both springs broke on my double door, and I had no idea who to call. I asked my smart phone for garage door repairs and they gave me one company listed in Lebanon. I called and set up an appointment with the tech and he said he would be there in an hour. After 4 hours I called and they got me to the tech and here is what he said after my 4 hour wait: "We can't do that, you will need to call someone else." I asked if he needed to reschedule, and he said, "No, call some other company." My temperature was high and I looked on my computer and Precision came up on the screen. I looked it over real good, checked the reviews and called them on Saturday morning. They said a tech could be out by noon. The tech called at 10:30 and said he could be here by 11am if that was alright. It was. John showed up at 11, we greeted each other, I felt good as soon as I met him. He looked over the door, sure enough both springs broke, cable off. He gave me 3 options: just fix the springs and cable; do that and change out the rollers which were clearly rusted and lots of play; and do that with a life-time warranty. No pressure, he was ready to do whatever I said. I told him the first option for now, and he went right to work. My wife and I discussed that our door was over 14 years old and has had no maintenance at all, and we decided to have the warranty. No problem. John was through and thorough in no time at all. The door sounded amazing, we had gotten so used to the noise, until it was not there any more - smooth and quiet and efficient. I am so thankful the other company blew me off, so that I came in contact with Precision. Great job. I will recommend them to everyone. 5 STARS ALL THE WAY!
Incredible service. I heard the garage door spring break and knew it needed to be fixed. As it was Saturday at 12:15 I figured I would find someone to fix it next week. Did a Google search, found Precision and made a call. They sent Aaron right away (no extra charge for weekend or immediate service) He changed my broken spring as well as the spring on the other door, at my request, and was finished by 1:30. Aaron was very professional and did a great job, I'm a very happy customer.
You can choose from three basic types of steel door: (1) steel only; (2) steel with insulation on the inside; and (3) steel on both sides with 1-3/8 to 2 in. of insulation. Other features that add to the cost are thicker insulation and windows, especially insulated windows. The do-it-yourself tensioning systems also add a little to the door’s cost. Be sure to specify exactly what you want.
