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.

Typically, it will cost less to install a steel garage door without an opener than to install a custom wood door with a garage door opener. Recent innovations have also yielded high-tech doors with thick insulation and energy-efficient glaze, as well as finished interior surfaces and other significant upgrades. These are more expensive doors, but they are also extremely durable.

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.
After you’ve ordered your new garage door, we’ll perform a site inspection to confirm your door size. We’ll contact you to schedule the installation, and our professional installers will do the rest. They’ll deliver your door, take down the old door, reconnect your opener if there is one, seal your perimeter and provide a final walk-through where they’ll clean up the area and haul away your old door. Additional fees for haul away may apply in some markets. We are happy to provide answers to questions you may have at the time of your garage door and opener installation.

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.
The classic telephone bait-and-switch: This time-honored swindle, also called "false advertising", can show up in the garage door business. Here's how this scam works: When you call and say you have a broken spring, and ask for a repair price, you are told over the phone that the price is X dollars, which typically might seem a little better than the competition. When the repairman shows up, after looking at your broken door, he will casually and matter-of-factly tell you it will cost 2X. If they told you over the phone that it would cost X, well, that was only for one spring, and he must (he must, mind you) install not just one, but two. He will act surprised if you object, as if you should have known that from what you were told over the phone. If you expected to really pay just X, it was your fault for misunderstanding because you don't know anything about how garage doors should be repaired. (You will feel intimidated at this, since you honestly don't know anything, else why would you have called a repairman? Intimidation is a powerful tool against customer resistance.) If your door used only one spring to start with, he will insist on converting yours to two, telling you it is safer the next time a spring breaks. If you originally had two springs, he will tell you that he must replace both springs, and you must therefore pay double what was quoted. While it is true that converting or replacing both springs is a good idea, the bait-and-switch pricing is not. The "bait" is the low price quoted to you over the phone, which they never intended to honor, and the "switch" is switching the price to something higher on a pretense. This method of selling is literally criminal (for example, see Florida Statutes 817.44, all states have similar laws), but a service business can usually avoid detection or prosecution because there are no printed advertisements or other tangible evidence, just one-on-one phone calls. If you find yourself in the middle of this trap, then the proper response is to dismiss the repairman without paying a nickel. Don't expect that you will be able to negotiate a fair price with someone who is using criminal business methods. Certainly don't expect that he will accept a lower price because you accuse him of false advertising. If you absolutely cannot wait for another service call, then you'll have to accept the fraud, in which case you should do so quietly. People that use these methods typically have ways to mentally justify their behavior to themselves as a reasonable business practice, and won't react well to your suggesting otherwise, even though they are in fact small-time criminals, not shrewd businessmen.
The most common grade of torsion springs have an expected life of about 10,000 cycles. The hardened and tempered steel experiences tremendous forces each time the door opens or closes. Gradually, the steel fatigues with each flexure, and eventually cracks and breaks, usually releasing its stored energy in an instant with a horrific "sproing" noise or bang. If you average about two car trips per day, opening and closing the door a total of 4 times daily when you come and go, then that expected life becomes 2500 days, or only about 7 years. If you have an automatic opener, then if you're like me, you tend to cycle the door even more frequently, and can expect the need for spring replacement even sooner. Moreover, my three-car garage has three doors, so on average I can expect a repair job every few years. Over a lifetime, it is very economical to do these repairs myself.
Replacing or repairing garage door panels help the garage door operate properly. This means less headaches just trying to get through the day. In addition to ease of getting in and out of your home replacing or reparing garage door panels help preserve the value of the home. Curb appeal matters, especially if the home is going to end up on the market for sale. Any exterior improvement you do to the front of your home pays dividends in your curb appeal. That being said, garage door panel repair is one of the highest dollar fixes you can do for your garage door. The cost to repair the panel is directly associated to the repairman's hourly rate. Installation of new panels start at $240 for a 9' panel and $690 or more for a 16' panel. If you are thinking about replacing your panels, think twice, you might be able to get a brand new garage door for about the same price. Check your options with your professional before replacing your panels.
I was careful not to assume that the previous installation correctly oriented the right- and left-hand springs on the correct sides of the center bearing plate. They could have been installed backwards by an incompetent installer, resulting in them having been wound looser (larger diameter coil) instead of tighter (smaller diameter coil) than when in their relaxed state, and if so I would have corrected them on the new installation. The proper orientation of the springs applies their reaction torque from tighter winding such that it turns the drums to lift the door. Verifying this is a rather simple exercise in mechanical visualization, but does require some care to be certain of correctness. If you were to install the springs backwards, and then start to wind them in the wrong direction, then the torsion bar will start winding the drums backwards, and not holding against the vise pliers, which should be obvious to inspection. Winding a spring backwards also tends to screw the spring off the cones; this error cannot proceed too far before the spring slips off the cones.

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.
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.
Some of the best garage door openers offer special features like a backup power source or a timer that automatically closes the door behind you at a predetermined time. While the door openers we reviewed vary in terms of power, noise and efficiency, they are all effective in the all-important task of letting you come and go with the simple push of a button. Here are the criteria we used to rank the top garage door openers:
Wood garage door: There’s no substitute for the distinctive look of wood. It’s typically made of moisture-resistant cedar, redwood or cypress and offers the most flexibility for custom designs. Depending on climate and exposure, wood doors require more maintenance. The average cost for a 16-by-7 double door made of quality wood: $1,200 to more than $4,000.
While winding or unwinding, one must be mindful of the possibility that the spring could break during winding process itself. If that should happen while the spring is significantly torqued, hazardous forces on the winding bar will suddenly become unbalanced, and the bar will take an unexpected jump, possibly injuring your hand or anything else in its path. At the same time, the spring remnants, although captured on the torsion bar, will create a frightening racket that would give the bravest soul a start. So your winding technique should be firmly in control of the rods, and you should not be so delicately perched on a ladder such that a startle will result in a fall.
Resetting the drums, if needed: If the drums were incorrectly set in their old positions, one must reset both drums in new positions on the shaft. This is complicated by the presence of old dimples in the torsion shaft from previous setting(s), which must be avoided lest they improperly influence the new setting of the drums. To begin this process of resetting the drums, the door must first be lowered and resting level on the floor, the spring(s) must be in the unwound condition with their set-screws loosened, and the lift cables wrapped around the drums. If for some reason the door does not rest level on the floor, such as the floor being uneven, then insert temporary shims between the door bottom and the floor to bring the door up to level. Loosen the set-screws on the drums, and turn the torsion shaft to avoid the old dimples from the set-screws in the old drum position. Tighten the set-screw on the left drum (that is, on your left as you face the door from in the garage), creating a new dimple, and apply tension to its cable with the locking-pliers technique, enough tension to keep the cable taut but not enough to start to move the door up. Attach and wind the cable on the opposite (right) drum by hand until the cable is similarly taut, and set the screw, remembering that tightening the screw will tend to add a bit of extra tension to the cable. Both drums should now be fixed on the torsion shaft, with the cables about equally taut (listen to the sound when you pluck them like a guitar string) and the door still level on the ground. Setting the left drum first, and the right drum second, will allow you to take up any slack in the cable introduced by the left drum rotating slightly with respect to the torsion shaft as you tighten the set screws. This alignment and balance of the cables, drums, and door is critical to smooth operation and proper closing. If you have a single-spring assembly, the distance along the torsion tube from the spring cone to one drum is longer than to the other drum, which allows a bit more twist to one side than the other, and you may have to compensate with the setting of the drums.
Garage Door Installation – This includes the installation of a new garage door. Includes the door itself, the track, cables, springs, hinges, handles, locks and rollers.  It is the complete service and installation of a new door. We inspect all the parts, make adjustments to fit your garage opening, and service all elements during the installation process. Plus, we check to ensure all parts are in proper working order after installed.

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.
Finally, we also carry any and every residential garage door product that you need to have a state-of-the-art, secure and safe garage door. We are proud certified dealers of Clopay doors, the most durable and versatile doors on the market. With over fifty years of garage door manufacturing experience, you can trust Clopay quality, just as you can trust our team to install these highest-quality doors.

The torsion shaft with lift drums on the ends is above the door. The standard residential door shaft is a 1-inch outside diameter hollow steel tube. The inside diameters of the bearings, drums, and winding cones are sized to loosely fit that 1-inch diameter shaft. At the center is a bearing plate, on either side of which are the torsion springs, or in some cases just one larger spring. The spring pictured on the left in the photo is broken about 1/4 of the way in from its left end. The black shaft with dangling rope and door bracket is the track for the electric opener.


And for some extra features, you'll appreciate accessing the system through the MyQ smartphone app. You can set up this Chamberlain opener to automatically close the door after 1, 5, or 10 minutes, which is great for people who are a bit forgetful. We also really like the motion-detecting control panel, which turns on lights whenever it records nearby movement.
In 1992 the United States Consumer Product Safety Commission released new rules for automatic garage door openers. Anything manufactured after 1993 was required to include either an electric eye (a pair of sensors that detect an object obstructing the doorway) or a wall-mounted control button that users hold down in order to close the door entirely. Most manufacturers opted for the electric eye method, sometimes referred to as safety sensors.

Called for an appointment and was surprised that I could have a tech come the same day. Matt arrived ahead of schedule, inspected the garage door and gave me a tune up to get things working properly again. He explained what would need to be done in the future, and the cost. I will certainly call them when the time comes to get that work done.read more

Next, the torsion shaft is reassembled with the new springs, the drums repositioned loosely on the shaft, this whole assembly slid back into the end bearings, and the drum set-screws tightened down. I tightened the set-screws about 1/2 or 3/4 of a turn after contact with the shaft, which provides a good grip, but does not distort the shaft. The drums can be set on their old positions, if they were correctly installed, which is snug up against the end bearings to remove any longitudinal play in the torsion shaft. Now the lift cable can be reattached to the drums, and a slight temporary torque applied to the shaft to keep the cable taut while the first spring is wound. This temporary torque is conveniently applied with a pair of locking pliers clamped on the shaft, positioned such that they hold the torque by pressing lightly against the wall above the door, before you start the spring winding, The locking pliers stay on the torsion shaft until you have finished the spring winding locked down the spring cone(s) with the setscrew(s), and removed the winding bars. Then you simply remove them with the release on the wrench handle. I feel that any job that doesn't require a trick manipulation with either locking pliers or duct tape (or in the ultimate case, both!) is just too boring. My trusty pliers look a trifle rusty ever since I used them to clamp something on my outdoor TV antenna "temporarily" and left them out in the weather for, oh, several years. The white stuff on the drum is paint overspray from the original painting of the garage interior.


Checking if the lift drums need resetting: The old position of the lift drums on the shaft may have slipped or otherwise lost the the proper position, requiring a reset of the drum position on the torsion shaft. You will also reset the drums if you are replacing the lift cables, since the new cables will not exactly match the length of the old ones. Problems like uneven tension on the cables, or a tilted door, or a door that doesn't easily stay aligned with the tracks, can be due to an improper "set" of the drums on the shaft. So one shouldn't assume the old positions are correct. Setting the drums on a "fresh" part of the shaft will avoid the possibility of damaging the shaft from retightening in the same dimples.

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.
Loosening or tightening the set-screws is the moment of most risk, since the end-wrench is a potential missile if you slip, and your hand is close to the cone. When the wrench is removed and only the rods are in place, it would seem that the worst that could happen is that the rod is flung out and the captive spring and cone rattle around, assuming you are keeping yourself clear of the rod's radial disk of rotation, and not leaning on the rod such as to fall into the apparatus were the rod to slip out of your grasp. The torsion shaft design has the virtue of capturing the mass of the spring and cones reliably on the shaft, preventing these parts from launching themselves as projectiles, even in an accident.

We have garage doors in different styles, materials, colors, designs and what-have-you. If you still cannot find what you are looking for, we can always source them out for you.

Smartphone Control: Many newer garage door openers allow you to connect the device to your home's Wi-Fi network, according to RW Garage Doors. You then can open and close the door through a smartphone app. In fact, many of these apps will give you an alert on the smartphone when the garage door is open for a certain period. Some opener models even can connect to your existing Smart Home system, incorporating all your appliances on one system.

Weight and cost: The 24-inch-long spring has a calculated weight of 8.4 lbs, not counting the winding cones. At less than $1/lb wholesale, and $3/lb retail for fabricated steel products, this spring should sell for about $8 to $25 (2005 prices) each, depending on the market and source. Since a pair is required, the expected cost for a pair is $16 to $50.
Luckily, there is a bit of science to questions of garage door repair and replacement. That’s why we’ve put together this guide on when to replace a garage door. We’ll prepare you to compare repair vs replacement garage door costs. We’ll discuss the ways in which repairs are the most affordable option while also exploring those moments when replacement will in the end provide you with more value added.
Spring rate, torque, and lift: The spring rate K for these measurements is π*28.5*10^6 * (0.273)^4 / (32 * 140 * 1.72) = 64.5 IPPT. Applying 7.5 turns on this rate will yield a torque of 7.5 * 64.5 = 484 in-lb, which on the 4-inch drums (2-inch radius) yields a lift of (484 in*lbs)/(2 in) = 242 lbs. Again we find good agreement with the approximate door weight of 238 lbs.
Kevin gave 30 mins advance notice via text before arriving, and he was very friendly and knowledgeable about the Chamberlain garage door opener that we ordered on Amazon. I was pleased with the thorough model description provided, and customer reviews which helped with our decision making, and our package came on the same day that it was ordered! I liked the process of choosing 3 preferred appointment times, and receiving a confirmation email which included Kevin's picture. The install price was very reasonable, and I would gladly use your Home Service again!
Most electric garage door openers have two lights: one in front of the opener and one behind or sometimes they sit side by side. They should provide enough light for you to get into your home from your car. Generally, people don’t leave the garage light on when it’s not in use, so it’s nice to have a temporary light when you arrive home. The length of time the light stays on varies according to how it is programmed. In most instances, you don’t need more than a few minutes from the time you leave the car to when you enter your home.

If you have an oversized door, one made of a heavier material such as wood, or a one-piece door, you should consider getting something stronger. In these cases, look for a garage door opener motor rated between 3/4 horsepower and 2 horsepower. There’s nothing stopping you from using a 2-horsepower opener on a smaller door, which can make for smoother operation and a longer service life, but high-horsepower units cost more.
Screw-drive garage door openers aren't as popular as some other types, but feedback indicates that those that give the Genie Excelerator a try are largely very happy that they did. It's a fast performer, owners say, and the company claims that it can move a door at a rate of up to a foot per second. It's relatively quiet, too -- perhaps not the absolute quietest that you can buy, but certainly quieter than a chain-drive opener, and quieter than older screw-drive openers, users report.

Checking if the lift drums need resetting: The old position of the lift drums on the shaft may have slipped or otherwise lost the the proper position, requiring a reset of the drum position on the torsion shaft. You will also reset the drums if you are replacing the lift cables, since the new cables will not exactly match the length of the old ones.

Speed of a thrown winding bar:: The springs, being in balance with the door, effectively are able to launch a typical 150 lb door at 10.6 mph speed. An 18-inch long by 1/2-inch diameter steel winding bar happens to weigh about 1 pound. Since momentum is conserved, this 150:1 ratio in weight of the door to the winding bar means the fully-wound springs could potentially throw a winding bar at 10.6 mph * 150 = 1590 mph = 2332 ft/sec, assuming the energy were perfectly coupled and transferred. If the energy transfer were only 1/3 efficient, this would still be the 800 ft/sec speed of a typical pistol bullet. Except it is a foot-and-a-half metal spear, not a bullet.

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.
