The torsion springs on steel rolling doors work the same way as other torsion springs in the garage door industry. When the door is closed, the spring is wound. The spring is secured to a spring anchor bracket on one end and to the shaft on the other. When the steel rolling door opens, the spring in the barrel supports most of the door weight. The remainder of this weight is lifted by the chain hoist or the operator.
The low rating on the CS is due to the fact that inwas out of town and my wife called because the garage door wouldn't open. We had repairs to the only other exit, and the CS said because it could be opened manually, it was no emergency. She was stuck in the house for over Sixteen hours. No emergency crew came out. Steve, a tech who came out the first time, fixed the door. It is not his fault CS took their sweet time to help a 45 year customer. I commend Steve. I do NOT have anything good to say about CS.

Given the complexity of a garage door and opener system, there are a variety of different areas something could go wrong. If your garage door shakes or is very loud during operation, the garage door closes all the way only to immediately open back up, the garage door opens slowly or closes too quickly, or the garage door opener and remote aren't working at all, you should seek help from a professional garage door repair specialist.
Torsion springs have three advantages over extension springs: They’re quieter, safer and easier to fine-tune. Torsion springs are quieter because you don’t have a spring knocking against a roller track. They’re safer because when a spring breaks, it usually stays on the bar. Finally, you can fine-tune the tension on a torsion spring so the door is perfectly balanced. Setting the tension on torsion springs has always been very dangerous, but torsion and extension spring systems with easy, do-it-yourself tensioning (Photo 7) are available. If you don’t use one of these DIY-friendly, easy tensioning systems (Clopay EZ-Set Spring and Wayne-Dalton TorqueMaster are two brands), you should hire a professional to release and set the tension on a torsion spring.
"The doors, tracks and openers were installed in a few hours. They look great and add so much to our exterior as well as quiet and warmer in the garage. The technicians tweaked the pad installation as we needed. They were on time, professional and courteous. I give them 5 stars. My only ding on performance was filling up our rolling recycle bin with intact noses that we had to pull out and break down. I thought the boxes would have been hauled away."
Overhead garage doors weigh hundreds of pounds, and doors that are not properly maintained or which are equipped with older automatic garage door openers can be safety time bombs. All too common are the tragic stories of garage doors injuring or even killing children or pets who found themselves underneath a closing door. Modern automatic door openers with auto-stop and auto-reverse mechanisms have greatly reduced such accidents, but mishaps can still occur if the door and door opener are not properly maintained.
Because it was a Saturday and I knew the garage door company I usually use wasn't open week-ends. I decided to look on the internet for week-end workers. The first site that came up was Precision Overhead Garage. Their website said if you call before noon, you can get an appointment that day. Even though it was 1pm, I decided to call anyway. After explaining that I couldn't close or open my garage door, they told me they would go ahead and schedule a time that day...even though it was after their same-day service cut off time of noon. They told me the technician would arrive between 3pm-5pm and he would call before coming (that was nice because I was able to run errands locally and not have to wait at home for those 2 hours). I also have to mention that although the company used an answering service to take the call and schedule the appointment, the gentleman that helped me was also very professional and courteous. Derrick, the technician that was assigned to the repair, called to tell me he was on his way. It was also within the arrival timeframe the company had promised. When he got to my house, he was polite and professional. He assessed the problem and made sure that I was clear about the cost of the repair and the cost of the service call. I agreed and he immediately went to work. He never tried to sell me any other services or parts or repairs that weren't needed. He was finished within 45 minutes and the door worked perfectly. I was able to pay with a credit card even without them being able to verify the information because it was a week-end. I was very impressed that they did that, especially because I was a new customer and had no history with them. Obviously, by my 5-star rating, I would recommend them to anyone who is looking for a professional garage door company. Thank you to Derrick and Precision Overhead Garage Door Service!!
