Spring index lower limit: DASMA standard 102-2004 provides a lower limit of 6 for the spring index, which is symbol C in our formulas above (section 9.3). Other interesting items in this standard include an upper limit for how much the door sags when raised (no more than 1/120 of its width, section 9.2.1), that each of the two bottom brackets should sustain twice the door assembly's weight (section 9.2.2) for a total safety factor of about 4, and that the lift cables should provide a safety factor of 5.
When you install a new garage door, replace all the hardware as well. If your automatic opener doesn’t have an automatic reversing system that includes photoelectric eyes, replace it. Doors with openers also require two extra pieces of hardware that you’ll see in Photo 4: a support strut (usually included in the door kit) and an opener bracket (not included). For doors with torsion springs located over the door, spend the $50 or so to have a garage door professional release the tension.
Note the left winding cone with red spray paint. This shpritz of paint is applied to create fear and doubt in the mind of the do-it-yourselfer. Sometimes it is a color code for the wire size (using a DASMA standard, red indicating 0.2253 inch diameter wire). Sometimes it indicates the winding direction: red may indicate right-hand winding, but don't rely on that; do you own independent analysis. Sometimes it is a manufacturer's private code for another dimension than wire size. This color code is for the installer's information when the spring is new; I would not depend on interpreting the color code properly on an old spring, since one can't be certain of a correct interpretation without documentation from the original supplier.

Cost was $88 for 2 pairs of springs, plus $21 shipping. (I had to order 2 pairs to meet the $50 minimum order.) They came with new cones inserted as shown at that price, so I didn't bother trying to remove and reuse the old cones to save a few dollars. The cones are quite difficult to remove from old springs and to insert in new ones, and the spring supplier will have the right tooling to do that easily. That was the best price I could find on the Web at the time, and didn't seem out of line with what parts like this might cost at at the building supply (if they only sold them). Contractors buy these much cheaper in quantities; they're just an ordinary high-carbon steel wire turned on a winding machine. I also found Web sites asking a lot more money, obviously trying to cash in on search-engine traffic from do-it-yourselfers. Others report that some local dealers sell springs at retail, but at a high price that eliminates any economy versus having them installed.
While you can certainly redo any security features on your garage door, it is often wise to replace the entire door if in fact that is the way a burglar gained access to your house. A new security code may seem like enough, but you don’t know how the thief figured out the old code in the first place. If the motor was disengaged, the issue might be a design flaw in the door itself. The best way to ensure that the thief doesn’t return or another thief doesn’t take advantage of the same unknown security weakness is to install a new door. Again, doing so with give you access to the kinds of robust security features that are being installed and implemented in the newest garage doors on the market.

Not only was the upward-lifting garage door and the electric garage door opener invented by Overhead Door Corporation’s founder C.G Johnson in the 1920s, but we also have a tradition in excellence for garage door repair, service and maintenance. Even with the most reliable products problems can arise and when they do it’s important to know who to contact to fix these issues while providing solutions to prevent future complications.

The one excuse that makes the most sense is, "if we sell springs to a do-it-yourselfer, and he gets hurt installing it, we could get sued." I can sympathize with someone who wants to sell only to the trade and not bother with the risk of a spurious product liability lawsuit from an ignorant member of the public. But the lawn-mower dealers have figured out how to manage that kind of exposure, so this is not an absolute barrier to retailing garage door parts to the public. It doesn't explain why torsion springs at retail are virtually non-existent.
Winding "up" starts out easy. It finishes at the proper number of turns, by which time you are pushing against the maximum torque. Count the turns of spring winding from when the springs are slack. To be sure you're winding the right direction, all you have to remember is that proper winding makes the spring smaller in diameter and longer in length as it twists "in". On the standard door (most common), this means you push the winding bars up to wind up the spring, which is an easily remembered rule. This is very apparent and should be verified during the first few easy turns. You can also think about the correct winding direction in mechanical terms, namely which way the reaction of the spring will torque the shaft and drums, which in turn will lift the cable. This should all make perfect sense before you attempt the manipulations.
You must use springs that are matched to the weight of the door. You cannot compensate for the wrong size spring by adjusting the number of winding turns. If you do not know a proper spring size, then you or your spring supplier must calculate a proper size (see below) based on an accurate weight (within 5 pounds) of the door. So you must then in turn have an accurate weight.

Most wood doors are sectional roll-up doors, though a swing-up wood door that’s meant to be painted can be affordably built in the driveway from a wood framework and plywood. Custom wood doors are typically made of durable softwoods such as Douglas fir, cedar, redwood or cypress, or from hardwoods such as oak or mahogany. Appearance-grade hardwoods are relatively expensive.

Single panel doors are constructed from one monolithic panel. From the closed position a single panel door swings up and overhead with a hinge on each side (known as jamb type hardware) to the fully open position. A disadvantage of monolithic panel doors is that the swing up arc of the door occurs partially outside the garage. This means a vehicle must stop and park several feet in front of the door to avoid being hit by the garage door when it is opened.
If your door has two springs, most professionals and research online says that replacing both springs is the best option. Most torsion springs are rated for 10,000 close/open cycles. If only one of your springs is broken, both springs are still recommended to be replaced. Considering that your second spring will break soon anyways, this added on fix is only going to cost you about $50 extra to assure that you don't have to pay another service fee for a second visit.
This page is a description of how I replaced torsion springs on a garage door. You may find that my experience either frightens you from trying such a stunt yourself, or encourages you to give it a try. You may curse me for revealing the techniques supposedly known only to the trade, or perhaps thank me for explaining how it's done. All the secrets are revealed below. Even if you hire this work out, just knowing how it is done will help you shop for the best deal and avoid falling prey to overcharging tricks.

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.

The third stage of garage door opener technology uses a frequency spectrum range between 300-400 MHz and rolling code (code hopping) technology to defeat code grabbers. In addition to transmitting a unique identifier for the remote control, a sequence number and an encrypted message are also sent. Although an intruder could still capture the code used to open a garage door, the sequence number immediately expires, so retransmitting the code later would not open the garage door. The encryption makes it extremely difficult for an intruder to forge a message with the next sequence number that would open the door. Some rolling code systems are more involved than others. Because there is a high probability that someone will push the remote's button while not in range and thus advance the sequence number, the receiver does not insist the sequence number increase by exactly one; it will accept a sequence number that falls within a narrow window or two successive sequence numbers in a much wider window. Rolling code technology is also used on car remote controls and with some internet protocols for secure sites.
Tools in Action says the Ryobi Ultra Quiet has plenty of versatility, as you can plug devices into the opener hardware, like a Bluetooth speaker, a fan, or even an 18V Ryobi cordless tool battery. When the opener has power, it will charge the battery. But if your home ever loses power, the 18V battery works as a backup to the garage door opener, allowing it to operate normally.
Capable of lifting a seven-foot garage door up to 500 pounds in weight, the SilentMax 750 comes with a number of convenience features for automatic and remote use. The included wireless keypad and dual remote controls will ​insure that you are the only one that has access to the door. Compatible with a number of in-car remote systems like HomeLink, you can also keep the remotes at home if you are worried about losing the “keys.”​
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?).
Two of the spring references specifically for the garage-door industry are the APCO Spring Manual by Bill Eichenberger, and the Torsion Spring Rate Book by Clarence Veigel; these give tables of spring sizes and torque constants. Spring engineering principles in general are described in the Handbook of Spring Design published by the Spring Manufacturer's Institute; the formulas allow you to calculate torque constants knowing only the geometry and the Young's modulus of the material. You can also find some brief spring information in standard references like Machinery's Handbook and Marks' Standard Handbook for Mechanical Engineers.
