A standard residential door raises 7.5 feet, but since the door goes horizontal this is equivalent to raising the whole door for half that distance, or about 3.75 feet. So if the door weighs, say, 150 lbs, then the energy supplied by the springs is 3.75 * 150, or about 563 foot-pounds. This is like throwing a 50-lb sack of cement up a 11-foot flight of stairs. Or catching a 50-lb sack of cement dropped from 11 feet up.
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. Garage door repair services are also required in emergency situations, like when the garage door won't operate and the car is trapped inside or you've accidentally backed into the door when it was closed. Whether it's a specific repair of your garage door opener, a broken spring that needs to be replaced, or a bent or rusted track, The Home Depot's local, licensed service providers can get the job done quickly and efficiently.

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.
Another moment of truth arrives as the winding-up of the springs begins. (I am just posing here with the camera held out in my left hand. Except for lifting the door onto the scale, this was a one-man job, including the photography.) The position of the bars in this photo was necessary to take the photo, and does not show a correct winding technique, You should not have to swing the bar up as high over the top as shown. The lower bar during winding should swing from pointing down to pointing a little past horizontal. Then you hold that bar horizontal while socketing the other bar pointing down, apply force to that (now) lower bar, then remove the (now) upper bar, wind one-quarter turn, and repeat.
Follow the manufacturer’s instructions to assemble the opener and mount the rail to the header bracket above the door. Then set the opener on a ladder where you’re going to install it. The ladder (usually an 8-footer) holds the opener in position while you measure for your lengths of angle iron. If necessary, put boards under the opener to raise it.

If your garage door is opening slowly or making a lot of noise, the problem may not be your opener. So before you buy a new one, check for broken or wobbly rollers and brackets. But don’t replace the bottom roller bracket yourself—the cable attached to it is under extreme tension. You’ll need to call a pro. If you’re replacing the rollers, get nylon rollers. They operate quieter than steel rollers and cost only a few bucks more. Next, check the torsion spring (mounted on the header above the door opening) to see if it’s broken. When one breaks, you’ll see a gap in the coils. You’ll need a pro to replace a broken spring.

Luckily, your garage door is a pretty sound investment. According to Garage Wow Now, garage doors were ranked in the top three for home improvements whose costs are recouped through increased home value. Similarly, realtors regularly increased the list price of a home with a new garage door by 1 to 4 percent! That means, if you spend $2000 on a new garage door, you can increase the value of your home by almost $8000 if you have a $200,000 home. Furthermore, compared with the other two highest rated improvements — siding replacement and deck installation — a garage door replacement is far more affordable.
The optician's trick: The serviceman looks over your door with lots of scowling, chin-scratching, and tsk-tsking. You ask, "how much?" He replies with the fair price. If you don't flinch at that price, he says, "for the parts", while quoting a large additional cost for the labor. If you still don't flinch, he adds, "each," while pointing back and forth to your pair of springs. (I hope none of you service people are reading this!) I call this the "optician's trick" after the old vaudeville joke about lenses, frames, and left/right.
It you have a tilt-up door, you are looking at a $150 - $200 repair or replacement. If it's a roll-up door it's going to cost you more. Roll-up door spring repair or replacement is usually around $200 - $250 for a 2 car door. If the brackets need to be disassembled to remove the springs due to the shaft not sliding sideways enough it will cost you an additional $50 - $100.
Critical measurements: Torsion springs come a variety of standardized sizes, so you have to carefully measure the old springs to know what to order for proper replacements. Tables of standard sizes and designs are on the Web, such as here [www.industrialspring.com]. The four critical measurements (all in inches) are: (1) the wire thickness (which I'm measuring here with a dial caliper; you can also measure the length of a number of closely stacked turns with a ruler and divide by the number of turns in the stack, measuring 10 turns this way makes the math easy), (2) the inside diameter (not outside!) of the relaxed (not wound!) coil, (3) the overall length of the relaxed (not wound!) spring coils, not including the winding cones, and (4) the right- or left-hand winding of the spring. One must glibly quote those figures to the spring supplier, otherwise one's lack of expertise will be obvious, and one will not be worthy of buying the parts.
The Certified Technician, Rey Lopez, was competent, professional, polite, and willing to work. He quickly removed the old door and installed the new one. He then explained the vast differences between what we originally had and what we'd just purchased (stronger spring/tension rates; increased viability of door opening/closing life; beefier hardware; plastic vs. nylon rollers; stronger door reinforcement). Ray performed with alacrity his tasks and then demonstrated the quiet, solid way the door retracted--no banging after the initial rise from the ground. Finally, his attention to detail was so precise that he enabled another remote controlling all three doors, plus he capped some frayed wires, thus solving the problem of why the door opened intermittently. I would rate him a "6" on a scale of "1-5", meaning he went above and beyond our expectations. His "can do" attitude, coupled with the deference he showed, will take him a long, long way. May HaShem richly bless him in his endeavors!read more

In this article, we’ll tell you the difference between a safe door and one that’s unsafe. We’ll also give you the helpful tips you’re not likely to find in the manufacturer’s instructions to correctly, and safely, install a new door with a torsion spring and do-it-yourself tensioning. Installing a new, double garage door yourself will save you several hundred dollars and should take eight to 12 hours if you’re fairly handy. You can do most of the project yourself, but you should recruit help for removing the old door.

If this manipulative, we-are-your-nanny business approach is truly in our best interests as consumers, then we shouldn't be allowed near ladders, lawn mowers, or power tools. Those products are just as hazardous and prone to misuse as torsion springs, yet no one thinks of them as forbidden. The only genuine difference is that torsion springs are a hazardous thing you need only rarely, while a lawn mower is a hazardous thing you need all the time.

I've provided this information for free, in hopes it will help you either fix your door yourself, or find a competent professional service to do it for you at a reasonable price. If you've been helped by this Web page, as many have, all I would ask is that you create a link to this page (http://www.truetex.com/garage.htm) from any pages you maintain. You will thereby help others searching for complete and reliable information on this type of repair to find it with a Web search.
Manufacturers and distributors of torsion springs believe they are better off not retailing their product directly to the public. They believe they are maintaining higher prices for their product by restricting sales "to the trade." One brochure for parts even flatly stated, "We do not sell to the end user. We protect our dealers," which would seem to be prima facie evidence of an illegal restraint-of-trade scheme. But this is an old story which is true of virtually every product and service, going back to medieval guilds and before.
This work is risky, but the risk is comparable to doing your own car repairs, or climbing on the roof of your house to clean your gutters. These are dangerous things that many people can do safely, but that safety depends on intelligent understanding and application of proper techniques. Professional door repair technicians, who are fully knowledgable, skilled, and experienced, report that they nevertheless are injured from time to time, despite their best efforts. Coldly evaluate your abilities and motivations, to judge whether you can manage the risks of this work for the benefit of the money and time you might save.
