There are many steps to replacing torsion springs, but overall it's a simple, straightforward process. If you're inclined to attempt it, find a good online video tutorial (preferably done by a garage door pro) that walks you through the entire process, including how to buy the right size of springs. You can also buy new springs and any related parts online, along with the most important items that you need: the two solid-metal winding rods that you use to wind and unwind the torsion springs.

Test the garage door opener while the door is down. Push the wall button to operate the door opener. If the opener operates, the binding was setting the internal safety mechanisms off, alerting the opener not to close. Raise the door slightly and jiggle the emergency cord to lock the carriage back over the carriage base, and attempt to operate the door with the motor.

Sometimes, you’ll notice that your garage door closes all the way and then immediately goes back up instead of staying in the closed position. This issue usually arises with brand new garage doors that were just installed or older models that may need to be reset. If this happens, the most likely culprit is the open and close limit settings of your garage door opener.


A garage door that has a broken spring has nothing to support its weight. The size of the door and the type of spring system determines how difficult opening the door will be. A garage door should not be opened until the spring is repaired. However, when you need to get your car out of the garage, it may be necessary if you cannot wait for the repairman. Use extreme care when opening a garage door in this manner.
If you have a steel door, but want the look of a wood one, it is not necessary to change your entire garage door. Often, it may be possible to mimic the look of wood with skillful painting. Your local home improvement store may be able to provide good advice about the type of paint and brushes needed to mimic the look of wood for your particular door material.
If you have a garage door opener and you suspect a spring has broken, do not disconnect the opener from the door (by pulling the red emergency release handle) while the door is open. If you do, the door can come crashing down under its nearly full weight, with nothing to stop it. This is an extremely dangerous situation. It is never safe to leave the door open when a spring has broken because someone might try to close the door without realizing how heavy it is. Or, they might pull the emergency release handle on the opener.
These instructions were first posted in 2005, and they were updated in August of 2008. I have been frank about the hazards of garage door repairs and about my own accidents incurred while replacing torsion springs. For what it's worth, you might be surprised to know that I, too, have benefitted from producing these instructions. I have not had any garage door accidents since we first published these on the web in 2005. And, in as much as I have helped keep other DIY-ers out of the emergency room, I consider myself somewhat of a medical practitioner.
On average, to have your springs replaced on your garage door will vary anywhere from $200 to as much as $400 if you were to hire a professional.  Breaking the costs down, the springs, depending on the part needed and the size, will cost about $20 to $60 each.  Add in the labor, which can be $45 to $85 per hour, depending on your location, can bring the grand total to the estimate noted.   A tilt-up door, on average, will be about 20 to 30 percent less than a roll-up door.
For example, low headroom garage doors often have cable drums on the outside of the end plate and the torsion springs usually wind down rather than up. They normally have left wind springs mounted on the left side of the spring anchor bracket and right wind springs mounted on the right side of the bracket. The first part on the shaft beyond each torsion spring is the end bearing plate. Just beyond the end bearing plate is the cable drum. On these the cable often runs on the front of the cable drum. The bottom of the cable is attached to a bracket that wraps around the front of and outside the vertical track.
Unlike torsion springs, replacing extension springs has long been given the "green light" for DIYers, primarily because you can complete the job without having to deal with spring tension. The general process is simple and safe: open the door to relieve the spring tension (and secure it open with C-clamps in the tracks); disconnect the spring from the track bracket and the spring pulley, and disconnect the safety cable from one end; install the new spring, reinstall the pulley, and reconnect the safety cable, and you're done.

However, when a car is trapped inside, then it must be opened; otherwise, taking a cab or bus would be the only option left. Opening it would require help from another adult person or should be done by technicians. And every attempt in opening it, safety precautions should always be the first thing in mind. Never rely on garage entry openers when the spring is broken since it can cause falls and accidents. If the homeowner is not confident to open it or has no time to do it, it is always wise to call a technician. http://www.youtube.com/embed/Z_eZc-kh40c


Locating a contractor - there are many professional overhead garage door companies. It is always advisable to contact at least three different agencies and request a bid or quote for the work.

Standard prices range from: https://www.youtube.com/watch?v=Z_eZc-kh40c&app=mobile
Garage door springs don’t require extensive care and maintenance. However, they also can’t be left entirely to their own devices. Spraying the springs with WD-40 is a good place to start. It’s also a good idea to check the balance of the garage door every year. To do this, simply lift the garage door up about halfway and let go. If the springs are in good working condition, the door should remain still. If the springs are beginning to weaken, the door might sag or fall. By taking these basic steps, you can preserve your door springs for longer.

The national average for garage door repair cost is between $80 and $110. Some of the factors that affect your garage door repair cost are the type of springs (most often torsion or extension), the size and weight of the door, and the door material. Many garage door pros will charge a service fee to visit your house and determine the problem. Often, the service fee includes a set amount of labor. One example of this is an $80 service fee that includes the first hour of work plus testing and inspecting your garage door and garage door opener, while another pro may charge $150 for the same standard service call.

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.
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.
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.[7]
Aging garage door springs cause the door to effectively "weigh" more as the steel loses its resiliency. With new springs, a heavy garage door should take no more than about 10 pounds of force to lift into an open position. With springs nearing the end of their lifespan, the force required to lift the door can be considerably more, since a garage door may weigh 200 pounds or more.
If you have a single-car garage, an extension spring will do the job. If you’re looking for a smoother motion and an ability to lift heavier doors, you may be better off selecting the torsion spring option. And if you have a two-car garage, your door will likely be too heavy for an extension spring. In this case, the torsion spring is the better choice.
Maybe the battery died or a spring broke, but you can't get into the garage to even see what the problem is. If the garage door is the only way in or out, or if you can't find the key to the door, you'll have to either find a way to break in or call a locksmith. As a preventative measure, it's smart to keep a spare key or install an emergency key release that would allow you to release the emergency disconnect to the operator so you can manually raise the door.
11.2b If the springs you installed are too strong, and if you wind the springs the correct number of turns, the door will not stay down nor half way. The garage door will be hard to close. DO NOT REMOVE MORE THAN HALF A TURN OF SPRING TENSION TO CORRECT THE PROBLEM. Here's why. If you remove 3/4 of a turn to get the door to stay closed, and then if you open the door, it will get heavier as you open the door, and once open, the cables will come off the drums. This could create as much as a day's extra work. It could also cause door damage and/or result in serious injury. Do not use the door! Get different springs!
Homeowners have long been warned that torsion springs are extremely dangerous to work with and that replacing them must be left to a professional. But these claims are somewhat exaggerated. If you understand how they work, and you pay attention to what you're doing, you can replace them safely and surprisingly easily. Granted, they're a little spooky to work with at first (partly due to their reputation), but this is a good thing—you really don't want to forget that they're under tension. Thinking about every step — before you take it — is the key to staying safe.

Garage door problems don’t have to mean the end of the world. Garage door repair is typically a one-day process and can be done for only a few hundred dollars. Common garage door repair requests include fixing slow or erratic garage doors, addressing strange sounds coming from the garage door or motor, fixing cosmetic damage such as dents or scrapes, repairing broken doors that are stuck open or closed, and troubleshooting inoperable doors.

The average cost is $190 for 2 springs in the Detroit area. This is for steel doors weighing under 140 lbs or known as a standard spring which fits 90% of all doors. The remaining 10% are wood doors or large heavy insulated doors. Expect to pay an additional $60 - $100 for a set of these. Garage Door Companies rarely carry these springs on their vehicles or stock them. Therefore, they either buy them locally at a premium or special order them. Regardless, its an additional trip that gets figured into the cost.
On one-piece doors with side springs, you open the door to relieve the spring tension, and simply swap out the springs on the opener-arm mechanism; there are no cables or pulleys to deal with, and the springs have internal safety rods. Some doors have tensioners that maintain moderate tension when the door is open all the way, and on these you'll have to loosen the tensioner in order to remove the spring.

The technician did a wonderful job - arrived on time and completed the job in less than 2 hours. I would have given him a 5 on everything if he had returned to add the additional piece (a piece that is fixed to the door frame for better insulation) to my door on the outside on the day he said he would come back. The piece he brought was of wrong color and he said he would be back with the right color the first day after New Year's Day to put up the piece. I hope he can come back soon.

6.13 Lower the second bar to the top of the garage door as you did the first bar. If your shaft is distorted inside the cone, you may need to tap the bar with a hammer as you unwind the spring. Maintain a firm grip on the bar; keep it firmly inserted completely into the cone; and be prepared at all times for the cone to slip, break, explode or snap loose from the shaft and jolt the bar down. https://www.youtube.com/watch?v=Z_eZc-kh40c&app=desktop
Roller doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings.[4] Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.
The winding and unwinding is done at a metal fitting, called a winding cone, attached to the outside end of the spring. You stick a winding bar into one of the four holes in the cone and use the bar as a lever to turn the cone. Once you've completed a quarter turn, insert the other bar into a different hole in the cone and let the bar lever against the closed garage door to hold the spring tension. This allows you to move the original bar to repeat the process, alternating the bars with each quarter-turn. It takes about 30 quarter-turns to fully tension a standard torsion spring. https://youtube.com/e/Z_eZc-kh40c
