Determine the inside diameter of the spring and the size of the coils. Run a tape measure across the opening at one end of the spring. Carefully measure the inside diameter of the spring so you can provide the supplier with this information. Then, use a tape measure to find the length of 10 coils on the spring. Divide the length by 10 to determine the measurement of a single coil.
Because your garage door is a major entryway to your home, it is important to keep it in good working order for your own safety, security, and convenience. Choosing the right style and appropriate materials will lessen the amount of repairs that may arise. Additionally, investing in regular maintenance can be cost-effective in the long run. If your garage door is in need of major repair, it is best to call a professional garage door repair company for assistance. Typically, the company will charge for at least one hour for making a service call. However, the benefits of a professional repair job can well outweigh any costs, as a professional can ensure the safety, security, and proper operation of your garage door.
What LCD said is more or less right. Those are the ranges you'd typically find you will have to pay, but it's important to remember that the rates vary across the country. One thing I always advice others to do is to get quotes from different contractors. It might not be the biggest job, but you'd be surprised how much difference there typically is in the quoted prices. If you check out the link I put in the resource, it'll take you to a site where you can get quotes from 4 different contractors at once. Under "Select service" you simply pick "Spring Replacement".
Most residential garage doors have one of two types of springs: torsion or extension. Torsion springs are heavy-duty springs mounted to a metal rod that runs parallel to the door, directly above the door opening. These springs are loaded, or tensioned, with a twisting action. When the door closes, cables attached to the bottom corners of the door pull on pulleys attached to the ends of the metal rod the springs are mounted on. The pulleys turn the rod, which twists the springs and creates tension. When the door is opened, the springs unwind and help lift the door. https://www.youtube.com/attribution_link?a=Z_eZc-kh40c&u=watch?v=XXXXXX&feature=share

If your garage door track is out of alignment, it can be a serious issue. The metal track your door runs on needs to be aligned properly in order for your door to move. If you see gaps between the rollers and rail, or bends in the rails themselves, you have a problem. The heavy weight of the door can compound these issues and make them worse until it becomes dangerous to operate your door.
If the door won’t move at all because of an alignment issue, then this problem isn’t one that you should try to tackle yourself. A garage door professional will have the necessary equipment needed to safely realign and repair your garage door. Additionally, if the track misalignment is beyond repair, a professional can install a new garage door track for you. http://youtube.com/e/Z_eZc-kh40c
