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.
10.6 Here you will need to do three things at once. With your left hand, lift the bar just off the top of the door and pull it toward the center of the garage door. While lifting up and back, tap the top of the bar just under the winding cone with your other bar. Pulling the bar back toward the center of the door as you tap causes the spring cone to bind on the shaft and not slip back.
You may remember a time as a kid when you and your siblings would close the garage door and run underneath it as fast as possible to make it out before the door closed. Well, on any garage door installed after 1993, that’s no longer possible thanks to two tiny photo eyes on either side of the garage entrance. These photo eyes transmit an invisible beam between each other that detects if anything is in the garage door’s path when it closes. This safety measure is there to prevent automatic garage doors from closing on top of someone or something and causing serious injury or damage to property.

"Our garage door wouldn’t shut on sunny days and the tech came out. He explained my options (swap the “seeing” sensor with the other, or replace them). He tried swapping and it was still an issue so he replaced them. In addition, he adjusted the spring because the company that installed it last year did not adjust it properly. He was here for about two hours and charged us for only the sensor replacement. Will definitely be using this company again! Highly recommend them. "


Many jobs around the house are fairly easy fixes. It’s relatively easy to clean out your fireplace, clean the leaves from the gutters or repaint a wall. It’s a different thing to replace your garage door spring. It’s careful work that is almost impossible to do correctly the first time. Garage door professionals spend a great deal of time learning how to do it properly, and even the most detailed instructions won’t make you an expert in the span of a few hours. It can be almost infuriatingly annoying at times and is simply better left to professionals.
Good response time and service; Question - I googled to find the Sears Garage Door repair phone number. During the conversation, I was unsure if this was "Sears" or a "contractor service" or other service. I had to ask if this repair person was coming from "Sears" or an independent repair. I was concerned until the service man arrived in a sears truck wearing Sears apparel. You might want the process to be more clearly identified as Sears.
If your garage door is not opening or has become jammed, you may need to replace the garage door cables. Unless you have the proper tools and know-how, this is a job best left to a professional due to the weight of the garage door and the extreme tension of the springs. The cost of repair will vary depending on your location, the length of the cables you need, and the time it takes the pro to do the replacement.
I'm getting a good laugh on all the comments on "Garage Door Nation" on how easy they or people make it sound to order and change out their torsion springs. First off, if you do your shopping, the savings is about $50 - $75 having a company do it. Is it worth the 3 days wait without the use of your garage door, the safety risk and your time doing it yourself? If yes, then go for it!
Instead, try other methods that might break the frozen connection between the door and the floor. For example, you can use a heat gun or hair dryer to melt the ice and free the door. Standard de-icing products can also work. And if you are careful not to damage the door or the seal on the bottom of the door, you can use a flat shovel or similar tool to chip away at the ice.
DIYers are generally steered away from working with torsion springs because installed springs are always under tension. To safely remove a torsion spring, you have to control the tension by holding the spring with a solid metal winding bar, then you loosen the spring from the rod and manually unwind the spring using two winding rods. The spring is potentially dangerous until it is fully unwound. By contrast, extension springs have little or no tension when the garage door is fully open.
Installing an overhead garage door requires a few tools and a friend to help. First, the lower door panel needs to be set up in the center of the doorway. The remaining panels and tracks are held in place with hinges, brackets, and screws. Set up an easy-to-install torsion spring system to ensure that your door lifts properly for many years to come.

A new garage door can add serious curb appeal, not to mention myriad home safety benefits. The cost of a new garage door will vary based on the type of garage door you want and the materials it will be made of. You can purchase a new garage door and have the pros install it for you, but proceed with caution as many installers won’t guarantee their labor if you didn’t purchase the garage door through their company. A new door (without installation) may cost anywhere from $200 to $4,000 or more, depending on size, brand and materials. Here are some examples of average new garage door costs, including installation:  
Next, if you don’t find an obstruction, check the springs. If your door has torsion springs, which are horizontal at the top of the door, you can tell they are broken by checking for a gap between the two springs. If your door has extension springs, you can check by looking to see if they are hanging on the side of the door. If you have a broken spring, you’ll need to call a pro to replace it as this is a dangerous task.

Look at the door rollers on each side of the door. All rollers should be inside the door track. If they are not, you will need to lower the door slowly by hand. If the bottom roller is out on one side, bend the outside edge of the track with a pair of vise grips and push the roller into the track before lowering the door. Bend the track edge back with vise grips.
There are two types of garage door springs: torsion and extension. Torsion springs are horizontal and located near the top of the garage door. Check for a gap between these springs indicating a break. Springs on the sides of the garage door are extension springs. Inspect them to see if one or both of them have broken. If you have a broken spring, call a garage door technician to fix it for you as soon as possible. Never operate a garage door with a broken spring; it could severely damage the door and the operating system. Never attempt to replace a broken spring on your own, either. Replacing broken garage door springs is very dangerous for anyone other than a certified, professional repair technician.
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.

Loosen the set screws while holding each spring with a winding bar. Position a sturdy ladder to the side of the springs, rather than working directly in front of them, for safety reasons. Put on eye protection and leather gloves. Push a winding bar into the bottom hole of the winding cone on the outside of 1 spring. Use a wrench to loosen the 2 set screws. Keep a firm grip on the bar as the the spring will expand powerfully as the screws are released. Repeat on the other side.[2]
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".

2.3 Beware of older winding cones. These older Crawford and McKee torsion spring cones were made for 5/8" bars. Sometimes, however, the holes are too small for 5/8" bars. Whatever you do, don't use a 1/2" bar; instead, grind down a 5/8" bar to fit. I recently had a McKee spring let loose after winding because I used a 1/2" bar when my 5/8" bar wouldn't fit. Just before it let loose I was telling myself, "This is not safe." And it wasn't. The only safe way to replace these older springs is to make a winding bar for each hole of each cone.

Remove the clamps and pliers from the torsion tube and track, and lift the door about 3 ft. by hand. If the door springs are properly adjusted, the door should stay in place when you let go. If the door falls when you let go, add a quarter turn to each spring. Repeat if necessary. If the door continues to open on its own, release spring tension in quarter-turn increments until the door stays in place when you let go. Then reconnect the opener.

7.2 If the spring bracket is slotted, vise grip the bracket to secure the shaft in the bracket. This will keep the shaft from possibly falling out and causing injury or damaging the garage door or shaft. You can also secure the shaft with a cable tie. Remove the bushing from the cone and leave it on the shaft next to the center spring bracket. Often the bushing gets stuck in the cone and customers will call us about getting a new bushing until they discover it is still in the cone of the spring replaced earlier.
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.
Next, if you don’t find an obstruction, check the springs. If your door has torsion springs, which are horizontal at the top of the door, you can tell they are broken by checking for a gap between the two springs. If your door has extension springs, you can check by looking to see if they are hanging on the side of the door. If you have a broken spring, you’ll need to call a pro to replace it as this is a dangerous task. https://www.youtube.com/watch?v=Z_eZc-kh40c
Vincent was professional, informative, personable, efficient, and cleaned up his work area as he worked. I told him and now I am telling you... He my "Jordan" of garages. Give him a raise or at least a bonus. Thank you for sending him for my install. I am extremely pleased with my garage opener & with his install and information I am confident in its operation. Thank you.

Because garage doors are large, heavy, and mildly complicated, most people who buy them take advantage of these services. But, if you’re pretty adept at DIY tasks, you can save some money and enjoy the satisfaction of doing the job of installing a sectional garage door yourself. (Sectional garage doors travel up and down on rollers that ride along tracks at each side of the garage doorway.)
A garage door with a broken torsion spring can fall rapidly and cause injury or death. However, the most common danger comes when your torsion springs break and you decide to undertake the repair/replace them yourself. Torsion springs can be very dangerous, and you not only need the exact tools for the job, but also need to have a good knowledge of the mechanics involved. Some of the parts involved in such a process can be life threatening, and must be handled with care and precision, which is why it is always recommended that you call in a professional, rather than trying to handle a replacement or repair by yourself. Failure to do so may leave you with injuries and/or damage to your property.

If your garage door is equipped with only one torsion spring, it will be much harder to get your door open. You will need to get 2-3 people to help lift the door up because the full weight can be anywhere from 150 to 300 pounds. We don’t recommend lifting the door when the spring break's due to the danger of it falling on someone. If you absolutely must get your garage door open, raw strength is what you need. When you get the door in the up position, use vise-grips or a c-clamp on the track below the bottom roller to hold the door in the up position.

10.8 After the cone reaches the mark, continue pulling the bar off the garage door and back toward the middle of the door with your left hand. Tighten both set screws 1/2 to 3/4 turns each after each screw first meets the shaft. This is the point at which you will feel the screw meeting resistance. If the garage door spring snakes after tightening the set screws, repeat the process and stretch the spring half as much as before. Residential torsion springs are stretched 1/8" to 1/4". Larger commercial and industrial overhead garage door torsion springs are stretched as much as an inch.
If you can hear your garage door motor running for what seems like the full amount of time it normally would take to open or close the door, but the door doesn’t move, chances are the disconnect switch has been enabled. Every garage door opener comes with a disconnect switch in case you lose power. This allows you to open or close the door manually so your car isn’t stuck in the garage until the power comes back on.
If your photo eyes are clean and the door still isn’t closing, the next thing you’ll need to do is check the alignment of the eyes. The eyes should be pointing in exactly the same direction and at the same angle. If they’re off, they won’t register that the other one is there, and it’ll assume something is in its path, causing the door to stay in the open position. When checking the alignment, measure the height of each photo eye from the ground. Use a level to make sure they’re pointing directly across at each other at the same angle. A laser level will make this part a little easier, but if you don’t have one, a regular level will work as well. https://www.youtube.com/embed/Z_eZc-kh40c
