Keep in mind that when the springs are released there is nothing to help with weight replacement. Garage doors weigh 150 pounds or more and if the door were not locked in place, there would need to be some way of holding it up until it can be lower manually. If no one is available to help, a clamp can be put on the track at the end of the door (Image 1). When ready, release the clamp and take the weight of the door.
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.
Every thing the tech demostrated was helpful, he knew how to do his job even if his eyes were shut. Very knowledgeable, took time out to explain every detail about the install process. Very highly satisfied. A d would love to have him for future additional repairs. Would definitely recommend sears and would use you guys again thanks mr.technician for a job well done.

A standard double garage door is 7 ft. high by 16 ft. wide. Standard single doors are 7 ft. high by 8 or 9 ft. wide. Because the doors are so large, few home centers and only some garage door stores keep many doors in stock, so expect to order one instead of buying it off the shelf. Garage doors are available in wood, fiberglass and steel. Steel doors, like ours, are light, maintenance-free, affordable, readily available, and have an insulating value as high as R-19.


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.


In the battle for best garage door opener bragging rights, it's Genie vs. Chamberlain. Chamberlain wins out overall, but Genie gets our nod for those on a budget. If the quietest operation and easy installation are most important, a Direct Drive/Sommer opener might be just right. And user feedback indicates that some Genie screw-drive openers are worth considering, too.
The electric overhead garage door opener was invented by C.G. Johnson in 1926 in Hartford City, Indiana.[1] Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.[2]
Torsion springs have three advantages over extension springs: They’re quieter, safer and easier to fine-tune. Torsion springs are quieter because you don’t have a spring knocking against a roller track. They’re safer because when a spring breaks, it usually stays on the bar. Finally, you can fine-tune the tension on a torsion spring so the door is perfectly balanced. Setting the tension on torsion springs has always been very dangerous, but torsion and extension spring systems with easy, do-it-yourself tensioning (Photo 7) are available. If you don’t use one of these DIY-friendly, easy tensioning systems (Clopay EZ-Set Spring and Wayne-Dalton TorqueMaster are two brands), you should hire a professional to release and set the tension on a torsion spring.

Direct Drive - Unlike chain- and belt-driven systems, where the motor remains stationary while moving a chain, a direct drive motor moves while the chain stays in place. Because of this, the only moving part is the gear the motor uses to move while lifting the door. To our knowledge, only one company makes direct drive garage door openers: Sommer. The company claims the motors are more efficient and quieter than any other type of opener. However, this is the most expensive type of opener we’ve found, costing around $286 on average.

Trading diameter for length: Observe that in the spring rate formula in the table above, factors D (diameter of coils) and N (number of coils) appear together in the denominator of the spring rate formula. Algebraically, given equal wire sizes, this means that the product of the coil diameter and overall length produces the spring torque, not the diameter or length alone. Physically, this means that you can trade off torsion spring coil diameter versus overall length in inverse proportions to maintain the same torque rate. Trade-off example: A spring with 2-inch diameter coils that is 36 inches long equals a 1.5-inch diameter spring that is 48 inches long, because the product in both cases is 72 (inches squared). This assumes that wire size is equal in the trade-off, and that you have not counted dead coils in the length. Service technicians use this principle to make quick substitutions for what's on their truck versus what you need. But if you understand this, you're ahead of many technicians who don't know this trick. Maybe now you can educate the next one you hire.
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.
I mentioned earlier that this apparatus had at least one prior spring replacement, with a single longer spring having been replaced by two shorter springs. The clamping of the original spring had pressed dimples and an eccentric distortion into the hollow shaft. While this distortion was large enough to block the old cones from sliding across, I was able to remove the old hardware by just sliding them in the other direction. I did not have to bother trying to press out this distortion, since I could just work around it.
The gentleman who showed up to my door was kind and very respectful. Introduced himself < Jeremy> and very professionally. He did an outstanding job and took time to let me know each step that was needed. Personally I would give Precision and the gentleman who came a big rating of a 10++++++ Thank you Precision and I would recommend your company to anyone.. A very pleased customer ... ..

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.

Align the upper roller tracks by carefully lifting the door halfway. Lock it in place with two locking pliers, and install the supporting brackets on the back of the rails using 1-1/4 in. perforated angle iron (available at home centers and hardware stores). Install 1-1/2 x 1/4 in. stop bolts, with the threads to the inside of the track, at the end of each upper track.

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.


The Genie SilentMax 750 belt drive garage door opener isn't as feature-packed as the Chamberlain B970, but its value is hard to overlook. The 75-HPc motor isn't as strong as the B970s, but is still plenty strong for any residential use, and the opener is widely judged to be pleasingly quiet. Smart features are built in, too, but using those requires the addition of the optional Genie Aladdin Connect module (Est. $95). The biggest downside is that there's no battery back-up.
Drive type Garage door openers work in a variety of ways. A chain-drive model raises and lowers doors with a metal chain — these tend to be inexpensive and able to handle heavier doors, but they’re loud. A belt-drive opener uses a belt and operates more smoothly and quietly. Screw-drive openers, which lift doors with a threaded steel rod, are also quiet and don’t require much maintenance. Finally, a direct-drive opener operates as a single unit — the whole contraption moves to lift the door. These tend to be the quietest, smoothest mechanisms available.
In each of our branches, we have the best team of expert professionals who know how to handle each and every type of garage door and its components. This is because all of our technicians go through a rigorous training process, covering every known garage door repair technique.

The not-so-competitive advertising trick: How about this racket: We have all heard how you should get at least three bids for any home improvement jobs, right? In some areas the largest ads in the yellow pages are from a single business using various names and phone numbers, masquerading as independent competitors. When you call asking for prices, "they" all quote you very high numbers. You are tricked into thinking you have shopped around for the prevailing price. (The more modern version of this is multiple Web sites that all direct you to call the same person.) If you've ever had to call a plumber you may have unknowingly been a victim of a similar trick.
Dodging a falling door:: Reversing this equation gives us x=gt^2/2 as the fallen distance x for a given time t. How much time would you have to dodge a falling door if the spring were to suddenly break at the top of travel? Let us assume you are 5.5 feet tall, so the door will hit your head after falling 2 feet from its 7.5 foot fully-raised height. This 2-foot fall takes sqrt(2*2/32.2) = 0.35 seconds (350 milliseconds). The quickest human response time is about 200 milliseconds, so even if you are alert to the hazard, this leaves you only about 150 milliseconds to accelerate and move your noggin out of the way. If you are an Olympic gold medalist in the 100 meter dash, you can accelerate (horizontally) about 10 feet/second^2, and your 150 milliseconds of wide-eyed panic will move you all of 10*0.15^2/2 = 0.11 foot = 1.35 inch.
The replacement springs in my case proved to be 0.2253 wire size, 2.0 inch (inside) diameter, and 24 inches long, in a pair of one left- and one right-hand winding. Actually, the old springs in these pictures were a slightly smaller size, but another similar door on this garage was better balanced by that size. Whoever installed the old springs didn't quite get the weight and size just right; it is not unusual to find a repair service installing a slightly off-balance spring size that happened to already be on the truck during the service call. My electric opener had no trouble handling the small imbalance. But since it is safer to reduce the electric operating force as much as possible through careful balancing, I chose the size that was working better on the other door. The Chamberlain brand electric openers (also sold by Sears) I have incorporate a plastic worm gear that tends to wear out after some years of use, requiring a disassembly and installation of a $20 repair kit; this wear is minimized by a properly balanced door.

Every thing the tech demostrated was helpful, he knew how to do his job even if his eyes were shut. Very knowledgeable, took time out to explain every detail about the install process. Very highly satisfied. A d would love to have him for future additional repairs. Would definitely recommend sears and would use you guys again thanks mr.technician for a job well done.
Step 5: Check for loose hardware, and tighten as needed. On swing-up doors, check the plates where the spring is mounted to be sure the screws are tight, and tighten any loose screws. On roll-up doors, check the hinges that hold the sections of the door together; tighten any loose screws, and replace any damaged hinges. Sagging at one side of the door can often be corrected by servicing the hinges. If a screw hole is enlarged, replace the screw with a longer one of the same diameter, and use a hollow fiber plug, dipped in carpenters' glue, with the new screw. If the wood is cracked at a hinge, remove the hinge and fill the cracks and the screw holes with wood filler. Let the filler dry and then replace the hinge. If possible, move the hinge onto solid wood.

If you're clever and equipped with a welder, you might think you could get away by welding a broken spring back together. At least two factors make this extremely risky. First, the weld itself may fail, either due to insufficient basic strength, or weakening of the nearby parts of the spring. Second, the fact that the spring was old and fatigued enough to break once, means that it is likely to break again soon at other location(s).
