SNAP... bang... boom. That is the sound of a garage door torsion spring breaking. It can be a very loud noise that sounds like a firecracker or gunshot. Springs are rated for a certain number of cycles and are the first thing that will break in your garage door assembly. Broken springs are the #1 source of customer calls for garage door repair companies. If you have a broken spring, you should NEVER try to open the door, as it can be very dangerous. This repair should be left to a professional or someone with the right tools and skills.
Measure the various areas where the door will be installed: door-opening height and width, headroom (from top of opening to ceiling), and back room (length of garage). For the headroom, you should have about 10" to 12" of space, depending on the spring system you're installing. For the back room, you should have the door height, plus another 18" or more of space.

When you hire a professional, the first thing they will do is turn off the power as a safety precaution.  They will then measure the existing door springs to make sure the new springs they order or have in stock fit accordingly.  With these new springs, they will unwind the existing springs and install the new ones in its place, tightening them with screws.  When tightened, the springs will be balanced, lubricated and the springs will be wound up.  Lastly, the door will be tested and the tracks will be lubricated to move efficiently. https://youtube.com/watch?feature=youtu.be&v=Z_eZc-kh40c
"I called Garage Door Medics Sunday night to request roller replacement on my parents' garage door. I was surprised to have someone call me ...back within the hour. Jeff was able to schedule the repair for 10 am the next day. I was very happy with the prompt scheduling. Jeff arrived on time and was very compassionate and professional. He gave my elderly parents a discount on the repair, and also lubricated the door and tightened the track, as well as adjusted the sensors. Rather than replacing just the single broken roller, he advised replacing all rollers since they would most likely break around the same time. So we did. He also showed us some things to watch out for like the bowing of the spring and advised that we have the spring positioned higher when it is replaced as it is creating more tension than necessary in its current position. I was very impressed with Jeff since he didn't try to sell us a spring replacement at this time since it could last a bit longer. He understood that my retired parents had limited income. I've had other vendors try to sell me everything they could. Thanks, Jeff! "

Standard torsion springs (about $40 each) have a service life of 7,000 to 10,000 open/close cycles. However, you can buy double-life (25,000 cycles) replacement springs for about $65 per spring. If you have a two-spring setup and one spring breaks, the second spring will break soon. So replace them both at the same time. To get the right springs for your door, you'll have to provide the supplier some details. Here's how:

6.8 Properly tightened screws will loosen with less than a turn. Once you loosen a set screw, keep at least one bar in the cone AT ALL TIMES until the spring is fully unwound. Many cones have been over-tightened. The spring may unwind 1/4 turn and not unwind any more until one of the set screws is loosened some more. You may need to completely remove the set screws. The shaft may be distorted and the cone still may not unwind at all.


Usually, when a garage door spring breaks the door has already closed or come down. In some instances, however, a spring can snap while the door is closing or in motion, causing the door to fall rapidly. In these situations, the door can become a safety concern for you and your family, so you should keep your distance and call a garage door professional as soon as possible. Garage doors are very heavy and can cause injury if not handled properly. When a garage door problem occurs, call a Sears Garage Door expert to help.
