The door and tracks at this stage of the repair are in a minimum-energy condition. This is a good opportunity to work on any hinges, bearings, rollers, cables, or tracks that need tightening, repair, lubrication, or replacement. Again, these parts should be available from the spring source, and should be ordered based on a pre-inspection. Home-improvement stores carry some of these parts, but the type and quality may not be the best.

All measurements should be in feet and inches. Step 1, measure across the existing door or desired space for the width, then up and down for the height. The rough opening of your space should be the same size as the door. Step 2, measure the sideroom, which is the space beside your door. Measure the width of the left side, and then the width of the right side. Step 3, measure the space above the door, which is called the headroom. Measure the height of the distance between the top of the door opening and the ceiling. Step 4, measure the ceiling, which is called the backroom. You’ll need to measure the distance of the garage door opening toward the back wall of your garage. You should have 6 total measurements in all once you’ve finished measuring the space. Keep in mind that having an automatic garage door opener installed might call for additional backroom or ceiling space.

The material and style of your door as well as the replacement parts needed will impact the total cost of your project. It would cost less to install a steel door with no opener then it would to install a wood door with an opener etc... High tech doors come with enery-effecient glaze and thick insualation as well as finshed interiors and other upgrades. These doors are more expensive but are more reliable and durable.
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.
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 the United States, the Consumer Product Safety Improvement Act of 1990 required that automatic residential garage door operators manufactured on or after 1 January 1991 conform to the entrapment protection requirements of the 1988 version of ANSI/UL standard 325.[11] A requirement for redundant entrapment-prevention devices was added in 1993; such a system can use an electric eye, a door edge sensor, or any other device that provides equivalent protection by reversing the travel of the closing door if an object is detected in its path.

The technician that came out, Todd Noel, was very friendly and professional. He fixed my problem quickly and did not overcharge me for something that I did not need. He also made some great recommendations for future work. Because of his level of service and my customer experience, I highly recommend Precision and will use them again in the future.
Single panel doors can also be installed with (one piece track type hardware) that folds the door back with a single horizontal track on each side (which is mounted at the top of the wood frame) and a roller, (mounted to the top of the door on each side. A hinge on each side that attaches to the bottom of each side of garage door. Using track hardware, a car can be parked much closer to the door, as the whole door, when in the open position, rests completely inside of the garage door header. Track type hardware has much less arc when raising and lowering the garage door as opposed jamb type hardware.[citation needed]
Horsepower You’ll also want to consider the horsepower of your opener. Typically, 1/2 horsepower will work for most doors in newer homes. If you have a heavier solid wood door, though, you may want to opt for 3/4 horsepower so it can lift it with ease. You can also get 1 and 1 1/2 horsepower models, but those are a better fit for commercial or special situations.

Horsepower: The horsepower measurement, often shortened to HP, describes the power the garage door opener motor has. A motor with a greater horsepower measurement will open and close the door more quickly, while also being able to handle larger and heavier doors. Motors between 1/2 HP and 1 HP are the most common for residential garages, FeldCo says.

Modern garage door openers include basic to advanced features that improve safety and deter break-ins. Examples include an automatic stop if a descending door encounters a solid object such as the hood of a car and light beam sensors that detect the presence of an object -- or a person or pet -- and stop a garage door's downward movement before accident or injury can occur. Available security options include remote lockouts for when you will be away from home for an extended amount of time, remote codes that change after each use, and lights that turn on automatically when your garage door opens or if movement is detected inside.

It’s important to pick a door that suits the style of your house. If you live in a Craftsman bungalow, for example, you might want something that looks like the swing-out doors found on garages behind early Craftsman houses. Manufacturers of modern roll-up doors make them in styles that mimic the old swing doors, complete with faux strap hinges on the sides and a pair of handles flanking a deep groove in the center. 
Here’s an opener that comes with all the bells and whistles. Featuring an ultra quiet belt drive, you’ll be thankful you purchased one like this especially if you have a room positioned near or above the garage. It’s also got battery backup so if the power goes out, you can still get in and out with ease for up to 20 open and close cycles for the first 24 hours of an outage. And for the technology savvy will appreciate its MyQ smartphone control technology that allows you to control the door via an app on your iPhone or Android, plus you’ll receive safety notifications if you’re away from the house and the door opens or closes. And for extra peace of mind, there’s also a feature that will automatically close the door after a set amount of time — you know, just in case you forget.

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.

A rolling code is a protocol used by garage door openers to keep your door safe and secure. When the radio signals from your remote control are broadcast to your garage door opener, it uses a specific code to communicate. Older models used the same code every time, making garage door openers vulnerable to burglars using a radio frequency identifier device. 
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).
At first glance, there appears to be a wide variety of garage door opener brands, but a closer look reveals that most openers are made by just a handful of companies. For example, Chamberlain garage door openers are well regarded in their own right, but the company also makes garage door openers for Craftsman and LiftMaster. Likewise, the Overhead Door Co. manufactures Genie garage door openers in addition to its own brand.

The open-ended work-order trick: You may be very surprised if you allow work to proceed without signing a work order with a specified price. Or, you may sign a work order, and think you're protected against open-ended wallet-reaching, only to find a much higher price due at the finish than you expected, because you signed a "parts as needed" order that got loaded up with a long list of parts (that likely were still in serviceable condition). You might have been quoted a price, but then get a bill for that price plus a lot more added for the "service call" and the "parts", and be told the quote was just for the labor. While this is the normal way of abusing your finances down at the hospital, you shouldn't agree to it for a garage door service call. These guys are not doctors.
I was having an issue with my garage door that turned out to simply be the remote lockout being accidentally engaged. I called Aaron’s Garage Door Service and rather than sending a tech out and charging me for such a simple problem, they explained the solution over the phone. I really appreciate businesses with a sense of integrity like that! If I ever have a real garage door problem, I will absolutely be calling these guys!

If you've researched this subject at all, you will no doubt have heard that you shouldn't be attempting torsion spring replacement as a do-it-yourselfer. That is generally good advice, so if you have any doubts about your abilities to do risky physical work on your own, hire the job out like everyone else. I found I was capable of doing this work with acceptable risk, because I intelligently understood the techniques, paid careful attention to methods and safety, knew how to use common tools in good condition, properly improvised the special tools I didn't have, and diligently attended to correctly performing a few moments of hazardous manipulation. I learned to do it purely on my own based mostly on bits of advice reluctantly given in Internet forums such as the Usenet newsgroup alt.home.repair. When I first wrote this page in 2002, there was no other do-it-yourself information available on the Web, and it was not until 2005 that reliable information disclosing the techniques started to appear elsewhere (see links below).
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?).

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.
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
Thus it is humanly impossible to dodge a falling door. If the spring happens to break when the door is moving up or down somewhere in the middle of travel, as is more likely, then you'll have even less time. Hence it is not prudent to stand or walk beneath a moving garage door. Of course people often do, and the only reason this does not frequently kill people is that springs typically break at the bottom of travel, where they are stressed the most.

Garage remotes work by sending a coded signal via radio frequency to the garage door opener. If this code matches that of the opener, then the motor will operate and raise or lower the door. Older devices use a single coded switch, whereas newer systems utilise a rolling code that changes each time the remote is used, increasing the security of the door by offering billions of combinations.
The disaster-is-nigh technique: As he inspects your door, the serviceman grimly calls your attention to "cracks" in your garage door. These appear very faintly in the middle of the door where the panels bow under their own weight when the door is up. This is normal, but the type of thing you wouldn't casually observe yourself. This surprising revelation disarms you, and you may find yourself strangely susceptible to the pitch for an entire new door.
Correct spring size is determined by factors such as the weight and height of the door. You cannot substitute a different spring and just tighten or loosen the winding to make it balance the load. Why? To maintain cable tension under all operating conditions, the spring must retain about one turn of unspent wind-up at the top-of-travel position, which with the lift drum size and door height predetermines the number of turns of winding at the bottom-of-travel; and furthermore the torsion of the fully-wound spring at the bottom-of-travel must be slightly less than that needed to lift the weight of the door when translated by the lift drums.
Cable fail-safe redundancy: Based on the proper setting of the drums on the torsion shaft, the two lift cables divide the lifting force equally to keep the door level as it rises. This not only levels the door, but also provides a fail-safe mechanism. If one of the cables should fail, such as from breaking or losing its end attachment, the other cable will then carry the full weight of the door. This will pull the door up on one side with twice the normal force, while the other side falls from its now unsupported weight, tending to make the door bind in its tracks and jam. Although not foolproof, this is a safety feature of the design which keeps the door from falling catastrophically if a cable were to fail while the door was traveling. The jammed condition also prevents a lowered door from opening with the hazard of a single broken cable, further minimizing the chances of both cables failing. Since if one cable fails the other must sustain the full weight of the door, the cables and attachments are rated many times the normal working load of half the door weight. A proper safety inspection of the door should include a critical look at the cables and their attachments.
Furthermore, newer doors come with more improved security features, helping to improve the way you protect your home and loved ones. While older doors are easy to break into, whether through breaking the lift mechanism or even using a universal garage door remote, new doors come with many redundant security features, which will go a long way in deterring even the most ingenious burglar.
If you’re replacing an existing garage door opener in your home, the simplest method for finding the right horsepower is to check the rating of the unit in your garage and get something with equal or higher power. Most homes have single- and double-car sectional garage doors made of aluminum or steel, which is the most affordable type of garage door. These doors are relatively light, so a motor with rating of 1/2 horsepower is more than sufficient. While 1/3 horsepower motors are available, they can wear out faster than those with 1/2 horsepower in such settings, so it’s a good idea to invest a little extra for a more capable garage door opener.

Install the stiffening strut on top of the top section of steel doors with the section lying flat. Then install the opener bracket that replaces the center bracket between the top two sections. While you’re working on the sections, protect them from scratches by putting carpet scraps on top of your sawhorses. Now, slide the rollers into the roller brackets.
Wheel Track Obstruction – Try closing the garage door manually to see if there are obstructions on the wheel tracks. If that is not the case, examine your tracks for potential damage like dents and bends. Look at your door to see if it is hanging unevenly. If the track is damaged or the door is hanging unevenly, it is time to call a professional for repairs. Track repairs can typically cost $133 to $154. Cost for correcting the uneven hanging of doors themselves can vary greatly, but typically cost about $125.
Torsion springs are devices that lift most of the weight of a garage door so that the door can be opened manually or by an electric opener. The torsion principle is applied via an efficient and economical apparatus consisting of a torsion shaft under spring torsion, which turns lift drums, which wind cables attached to the door near the bottom. All of this apparatus is mounted over the top of the door. The energy stored is sufficient, in an uncontrolled release, to break things, hurt you, or perhaps even kill you. The same could be said of jacking up your car to change a tire, or mowing your lawn, or raising children, so it is not crazy to want to do this yourself.
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.

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.
I was very pleased with the service provided by Alpha Omega Garage Doors. Randy was very professional and friendly. He arrived within the time window given and installed our key pad quickly and efficiently. He also took time to inspect the garage door and lubricate it. I would recommend Alpha Omega for your garage door needs and will use them again in the future for upkeep and to resolve any problems that should arise.
Right-hand versus left-hand winding: Springs are chiral, that is, wound or "laid" in either a left- or right-hand orientation. This is a critical property of their design and specification; you cannot substitute a left for a right or vice versa. If you were to grasp the spring in your hand, and if your right hand orients the tips of your fingers like the ends of the coiled wire when your thumb points "out" of the core of the spring, then you have a right-hand spring; likewise left (which end you grasp does not matter). (This also happens to match the "right hand rule" of magnetic polarity, if you happen to be knowledgeable in such esoteric subjects.) Another way to identify the winding is to examine the spring vertically in front of you; if the coils facing you rise going to the right, it is right-hand (thus you can remember, "rise to the right is right-hand"), and likewise left indicates left-hand. Another way is to view the coil axially; a right-hand spring winds in a clockwise direction as it recedes away, and a left-hand spring counter-clockwise. Yet another way, not so easy to remember, is to hold the spring vertically and compare the coil shape to the letter "Z" (indicates right-hand lay) or the letter "S" (indicates left-hand lay).
Note that I am measuring a spring that is fully relaxed because it is broken!. The length of the relaxed, unbroken spring is the specification of interest. It is harder to measure unbroken springs on an intact door because the springs should not fully unwind, even at the top-of-travel. If you can't be certain of the spring diameter from indications on the cones, then you have to go through an unwinding procedure to relax them fully for measurement, or perhaps reckon the size from measuring the somewhat smaller diameter at the nearly unwound condition when the door is at its top-of-travel (although one should not attempt to raise a door with a broken spring).
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.
Speed of a falling door:: Physics tells us that the transit time of a free-falling body is sqrt(2x/g), where x is the length of the fall and g is the acceleration due to gravity (32.2 ft/sec^2). If this typical 150 lb door were to fall an equivalent of 3.75 feet, this falling time would be sqrt(2*3.75/32.2) = 0.48 seconds (480 milliseconds). The terminal velocity is gt, or 0.48 seconds * 32.2 ft/sec^2 = 15.5 ft/sec = 10.6 mph.
Before carrying out any kind of San Antonio garage door repair, we try and understand the problem at the very first place. After being contacted, our professionals will go and visit your garage personally and find out the actual problem. They are the best people to suggest if the problem can be solved with repairs or if the garage door will need a replacement. Usually if the problem is a minor one, it can be tackled with repairs, but in case of grave issues, complete replacement of the doors is recommended.
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.

Stress and lifetime: Calculating the maximal stress in the wire is useful for estimating the lifetime. Using the formula above, the bending stress S in the spring wire is 32*238/(π*0.2253^3) = 212 Kpsi. The spring index C is D/d = 2.23 / 0.225 = 9.88. The Wahl correction factor is Kw = (4C-1)/(4C-4) + 0.615/C = 1.15. The Wahl-corrected stress is Kw * S = 1.15 * 212 Kpsi = 244 Kpsi. This predicts about a 10,000-cycle lifetime, which is the standard "cheap spring" configuration originally installed. Note that while this stress is proportional to the torque being applied, it is also in proportion to the inverse third-power of the wire size. Thus slightly heavier wire sizes (and suitably adjusted D and/or L) radically improve the expected cycle lifetime of the spring.
When I called to schedule the repair service, I was transferrd 5 times and spoke with 6 service reps. Each rep was very confused by my request to get my garage door repaired. One rep actually told me that Sears doesn't repair garage doors. I had to tell her that Sears installed the door. When I finally found a rep who could schedule my service, it took one week for the appointment.

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.
Spring rate and torque: In my spring replacement above, the wire size was d = 0.2253 inches, and the ID was 2 inches, giving a mean diameter D = 2.2253 inches. The number of coils is L/d = 24 inches / 0.2253 = 107, less about 5 dead coils on the winding cones, or 102 active coils. Thus the spring rate is K = (π*28.5*10^6 * (0.2253)^4) / (32 * 102 * 2.2253) = 31.8 in-lb/turn (IPPT). Winding 7.5 turns * 31.8 in-lb/turn yields a torque of 238 in-lbs per spring.
