Here's a view of my door and its broken torsion spring. This door is 10 feet wide and 7 feet high, constructed of 3/4 thick hollow wood panels inside with 3/4 inch plywood siding outside to match the house exterior. This is original to the house which was constructed in 1978, and is much heavier (238 pounds, as I measured later as described below) than the steel doors most common today in new construction. The 10-foot width is a little larger than usual for a one-car garage; such doors are typically only 7 or 9 feet wide. The ceiling height is 9 feet, providing 18 inches clearance above the torsion shaft. This is in a 3-car garage with 3 separate extra-wide doors. Every man's dream! ('cept when the door is broke.)
Install the vertical roller tracks first by wrapping the curved lip around the rollers. The top of these tracks should be approximately 8 in. below the top of the top section. Wait to install the upper tracks until this step is complete. Check the level of the top section to make sure the tops of the vertical roller tracks are level with each other. The bottom of the roller tracks should be at least 1/8 in. off the concrete floor. After leveling and mounting these tracks, install the upper roller (horizontal) tracks.
Since their invention in the 1920s, electric garage door openers have come a long way. Garage door openers work by using a trolley connected to an arm that attaches to the top of the garage door and slides back and forth on a track, which opens and closes the garage door. When operating the motor, a chain or belt turns and pulls the trolley along the track. A good garage door opener will have a horsepower of 1/2 HP, 3/4 HP, or 1-1/4 HP. Garage door openers have the ability to open and close a limited number of times in power outage emergencies. Security is something else to consider when purchasing an opener. It's helpful to have sensors that will stop the operation of the garage door when a person, vehicle, or other obstacle is in the way.
Garage door springs come in two styles: torsion (see above), which mounts on the header above the door, and extension (Photo 1), which floats above the upper roller track. In the past, extension springs were safer to install but didn’t have containment cables running through the center of the spring. Without cable, these springs become dangerous, heavy whips when they break. They also tend to be noisier than torsion springs, and we recommend you use them only if you don’t have the 12 in. of headroom above the door that a torsion spring requires.
When ordering springs, be aware that a number of different sizes of springs will make proper replacements, not just the specific size being replaced. The wire size, winding diameter, and length can be traded off to make springs of varied geometry but equivalent torque characteristics. This will also affect the expected lifetime (in cycles) for the spring(s). Since the critical specification for a replacement is the weight it is designed to bear, not the sizes per se, there are likely several stock sizes that replace a given old spring. The spring distributor's inventory may happen to offer only a different size with an equivalent weight-bearing specification. One has to judge whether to trust the advice of the seller in such situations. The seller should have the data to know what substitutions are proper.

Clopay, a garage door manufacturer, provides online installation manuals for their products. These include excellent mechanical diagrams and brief instructions for winding torsion springs on their doors. Of course, this is specific to their product designs, which may or may not match what you have. Note that some of their products involve the "EZ-Set assembly option" mechanisms that use a geared housing for winding (instead of standard winding cones) and non-standard geometry for the drums. Clopay should get an award for at least acknowledging in their instructions that you might be able to install your own new door (although they insist you must not take out an old one if it has torsion springs).

Even if one could somehow stretch and clamp the springs to the proper extra length, the process would still be more trouble, and there would be little or no reduction of risk. Lifting the full weight of the unsprung door by hand and clamping it in the raised position is dangerous in itself, and creates the same amount of stored energy as winding the springs, ready to slip out of your hands. Many doors won't travel far enough up the track to provide clearance to access the springs. You're also going to have to deal with winding stiff steel cables onto both lift drums at once without any resistance to maintain tension. Finally, even if you managed to complete the installation with the door raised, you then have to lower the massive door against an untested balancing torque. If you've made a mistake, then that massive door has nothing but your skeletal force applied through your meat clamps (hands) to prevent it from falling down and crushing whatever is in the way (perhaps your feet?).

How many times a day do you open or close your garage door? You probably don’t even know because we take our garage door for granted until…. Until it doesn’t go up… until it doesn’t come down… until it gets noisy, difficult to open by hand or some other problem develops. You need help – and if you’re locked in or locked out, you need help in a hurry. You need A-Authentic Garage Doors. Here’s why:
Prices, like the garage doors themselves, run the gamut. You can pay as little as $400 for a door that you install yourself, or several thousand dollars for a high-end premium door that includes all the bells and whistles, including installation. A mid-range, 16-by-7-foot door will typically cost from $750 to $1,500, installed. Premium insulated steel doors run from $750 to $3,500. According to Remodeling Magazine’s 2017 Cost vs. Value report, the average national cost of a garage door replacement is $3,304.
Those who benefit from this anti-competitive behavior have many excuses for it. They claim that the product is too dangerous and infrequently needed for the public to purchase directly. They say the job is hazardous and requires techniques and tools with which the amateur will rarely practice, which is true. They write me in anger saying I don't understand how expensive it is to put a truck on the road with a technician and parts and salary and benefits and insurance and advertising and every other common business expense. They say it will take the homeowner hours of effort to do this safely and correctly, while they can do it in a fraction of that time and at a price that isn't worth the effort to save. But should they set themselves up as the judge of what you can and cannot do? Of what is an economical use of your time? Imposing minimum order quantities or charging retail prices for small orders is legitimate; inquiring into the purchaser's background is not.
With hundreds of moving parts that are all required to work together, it's no surprise that garage doors may need occasional repair and maintenance.

Insulation, which increases energy efficiency and can help to lower utility bills, is crucial when a garage door is attached to the home. In this case, doors with high R-values are preferred. This means it has insulation that can keep the heat in. The higher the R-value, the better insulated your garage will be against outside noise and cold and hot air.
This is the electric opener which operates this door. I'm picturing it here because you pull the rope to disconnect the trolley, run the trolley under power to the fully-open position, and then disconnect power before working on the door. Then you should lock the door down with either the security lock or with Vise-Grips or C-clamps. This avoids the door lifting when you don't expect it as you are applying spring adjustments. It you were to foolishly overwind the spring without the door locked down, you could possibly find the door trying to leap up to the raised position when you aren't prepared. That would likely knock your grip off the winding rods, with potentially disastrous results. I like to work under the safety principle that serious accidents should be physically possible only when you make two or more stupid mistakes at the same time.

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.
With garage door installation costs, these numbers also include the actual purchase of the new door and other hardware, including the tracks, adhesives, connectors and fasteners. Keep in mind that if these numbers seem extreme, garage door replacement and upgrades can yield, on average, one of the highest returns on investments for homeowners — with an expected 85 percent.
Remember, not all garage door springs are alike. They are not one size fits all. If yours breaks, make a note of the brand and color code on the spring you need to replace. We'll get you the garage door opener parts you need, from seal kits to torsion and extension spring kits. Save money by replacing garage door hardware instead of replacing the whole unit.
