See the Sectional Overhead Garage Door catalog (PDF file) from the Prime-Line replacement hardware company. Their brochure Sectional Garage Door Torsion Spring Installation Instructions (PDF file, part number GD-12280) is brief but informative. Apparently you can only obtain their torsion springs as special order items through mom-and-pop type hardware stores like Ace and True Value, and not the big-box Home Depot and Lowes.

When your garage door starts acting up, more often than not it is telling you it's time to do a bit of maintenance. So, before hitting the panic button, try these simple repairs. First, examine the rollers and tracks. If you can't remember the last time you cleaned them (and they look the part!), give them a good brushing and then add some lubricant. Next, perform these simple garage door maintenance tasks.
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.
If you live in a home where there are living quarters directly above the garage, Garage Guide DIY says force-sensing technology built into the B730 ensures a smooth operation, no matter what temperature it is in your garage. The unit adjusts the motor's power on the fly, keeping it running smoothly. Amazon reviewer Steven Bone says the B730/WD962KEV opener runs extremely quietly and is easy to install.

Technician gave me a window of 1-4pm, I called at 330 to see if he was on his way. He told me he would be there at 4pm, reason being was because of the amount of work orders he had that day. He was also by himself, had no helper. I was very satisfied that he was able to repair my garage door. He was very professional considering he showed up on a Friday afternoon on a 100 degree day. Thanks again

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. 

You might genuinely need some extra parts when you thought you simply needed a broken spring replaced, and a good serviceman will perform a simple inspection to identify such parts. Nor is it unreasonable for a business to charge separately for a service call versus repair work actually performed. But the best protection for you as a buyer, being somewhat at the mercy of whomever you decide to bring on site, is to understand what is being done, and ask intelligently for a clear explanation or demonstration of why extra parts are required.
If your door feels heavy, it is likely that your springs have started to wear down and are no longer capable of bearing the weight that they once did. Now, don’t worry, just because a spring is starting to lose its strength doesn’t mean it will snap at any moment. However, simultaneously, a weak spring isn’t any safer to try and repair on your own.
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.

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.
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.

Trading wire size for length, diameter, or cycle life: Now we are really going to save you some money, if you just recall your high school algebra class (and I don't mean that cute cheerleader who sat next to you). If you further understand the role of the 4th power of the spring wire size (letter d in the formulas above) in the numerator of the spring rate formula, and how to increase or decrease d to compensate for changes in length, diameter, and cycle life, then you're qualified for elite spring calculations. Matching springs is a matter of equating the 4th power of the proportion in wire size change to the proportion of change in the diameter or length or the product of both diameter and length. However, it is usually best to only increase wire size when substituting a spring, since this does not derate the cycle life. If you observe that the formula for bending stress is proportionate to the inverse 3rd power of the diameter, then physically a proportionate increase in wire size will result in a dramatic increase in cycle life of the 3rd power of that proportion. Trade-off example: Yawn with me while we ponder my original spring once more. Let's say I was in a fit of engineering mania, and wanted to replace my spring having a 0.2253 inch diameter wire (d = 0.2253) with a 0.262 wire version (d = 0.262). How much longer is the spring with equal torque rate, assuming we use the same coil diameter? The proportion of this change is 0.262/0.2253 = 1.163, and the 4th power of that is 1.83. This means the length must increase by a factor of 1.83 (again, not counting dead coils). Recalling that the length in Example 1 was 102 non-dead coils, the heavier wire spring must be about 1.83*102 = 187 coils, which when adding 5 dead coils and multiplying by the wire size to get the overall length, is (187+5)*0.262 = 50 inches, versus 24 inches in the original. So using this heavier wire more than doubles the length (and thus the mass and thus the cost). While the cost about doubles, the stress goes down by the inverse 3rd power of the wire size proportion, or 1/(1.163**3) = 0.64. Sress is favorably, non-linearly related to cycle lifetime (halving the stress more than doubles the lifetime), so this decreased stress should more than double the expected lifetime of the spring. While the up-front cost is more, the true cost of an amortized lifetime is much less. In short, per cycle it is cheaper. Ah, the wonders of engineering calculations! Conclusion: Observe that the stress formula (and thus the cycle lifetime) depends only on wire diameter (d) for equal torques. Thus the only way to improve cycle lifetime is to use heavier wire. For equal torques, heavier wire size, due to the exponents in the formulas, increases cycle lifetime much faster than it increases mass (and thus cost), physically speaking.
Belt driven garage door openers offer a prime level of noise reduction if you want a silent environment in the garage. While common chainlinks will rattle during use, the smooth performance of a belt dampens noise as the garage door slides up and down. Using a 3/4 motor, the Genie SilentMax 750 will easily tackle any typical garage door while keeping the environment quiet and comfortable while in use.
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).

Before setting the last panel in the tracks, set the power unit on the actual frame and slide it in the ends. Hardened screws are used to attach the center bracket (Image 1). They are a different type screw — they are tougher and will last a lot longer. Make sure the bracket is level (to the eye) when installed and leave the bracket a little loose so adjustments can be made. Fasten down all the hinges (Image 2).

You might not think it could get easier than pushing a big button to open a door, but some garage door openers make things even simpler by offering keyless entry and multiple remotes. Many models come with a keyless entry pad that mounts outside the garage door so you can gain access without a remote. While a remote is preferable for most situations, there are times when you need to get into the garage and don’t have it handy, so this is a nice feature to have.
Current data from real estate firms throughout the country show that replacing the garage door raises the value of a home by an average of $2,810, according to Remodeling Magazine's report. Based on the average cost of $3,304, this means that replacing a garage door is expected to return 85 percent of the job’s cost, nationally. When replacing a garage door in the Western U.S., however, the return is predicted to be 110.8 percent of your investment.
Since we're using an 18-inch (1.5 feet) winding lever to wind each spring up to 29 foot-pounds, we must apply a maximum tangential force to the end of the winding lever of about 20 pounds. Later we'll see that the actual weight of this rather dense door is 238 pounds, implying a maximum tangential force on the winding levers of only about 13 pounds!

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.
Precision: I got a call from my wife instructing me to come home right away - my neighbors daughter had backed our truck thru our double garage door. When I arrived home there was a Precision truck in my driveway, wow you're fast! The door was pretty badly damaged, unsecure and could've come down more. Your technician Dannie Ray told us no touch, extremely dangerous". Since our door is out of production Dannie started calling and found a door in Tacoma, and Dannie takes off for Tacoma. He calls me at about 3:00 pm. and tells me he's about 1/2 hour away and he's coming back to install both new doors. Second wow! About 1/2 hour later here comes Dannie with 2 new doors and proceeds to go about his business. My wife and I had to leave we asked Dannie if he was good, he said no problem. We arrived home around 10 pm to brand new doors that work and look terrific. As a business owner and full time Realtor I appreciate it when I see such outstanding service and concern that truly is "above and beyond". Now if I or one of my clients needs anything to do with a garage door I now have you on speed dial. Again, Thanks for such a great experience in a difficult moment. Thanks again Dannie, come by anytime!
You garage door is one of your primary entrances to your home so you want to know that they are functioning properly at all times. If you are having complications with your current garage door, then you need to hire a professional garage door company to determine if it needs to be repaired or replaced. Included are the average garage door repair costs in 2016, for the United States. This is the latest information headed into the new year and is a great guide for 2017. I've also included some garage door repair costs pictures, graphics and graphs that include high, low and average costs for garage door repair, installation and replacement costs. It also includes garage door part repair and replacement costs.
A spring design manual, also called a rate book, gives tables that relate the torque constant ("rate") and maximum turns for springs of given wire size, diameter, and length. For example, a typical page in a rate book would show a table for a given wire size and inside diameter, the maximum inch-pounds (MIP) of torque available for a standard lifetime of 10,000 cycles in that size, the weight of the spring per linear inch, and the rates of the spring (as IPPT, inch-pounds per turn) for each of various lengths. From these figures one can calculate the lifting capacity, substitutions, conversions, and cycle life upgrades for a door of given weight and drum geometry. The weight-lifting capacity of a given spring is calculated based on its torque constant (IPPT, or inch-pounds per turn), which is the rotational version of the spring constant that characterizes the spring. The IPPT constant is found from tables giving IPPT for given spring dimensions (wire-size/diameter/length). The same tables may indicate the maximum number of turns for various expected lifetimes in cycles. The torque required to balance a given door can be calculated from the weight of the door times the moment arm of the drums (as we do below under "Calculating the Forces We Will Be Handling"). The ultimate torque of the spring in the fully-wound condition is the number of turns (when fully-wound) times the IPPT constant. Choosing a spring to balance the door then simply requires matching the ultimate torque of the spring to the balancing torque.
Lift cable placement: On the standard residential door mechanism, the loops at the lower ends of the two lift cables loop over the two bottom roller shafts which project from the bottom bracket on the door. The upper cable ends fasten to the drums using one of the methods described above. The drums are positioned along the torsion shaft such that the inner edge of each drum is approximately over the edge of the door. The cable winds onto the drum from outside in, so at the top of travel the cable is winding onto the inner edge of the drum, vertical from the edge of the door where it is looped over the roller shaft. As the door is lowered, the cable winds out to the outer edge of the drum, and thus is a bit out from the vertical, but the cable still falls in the gap between the guide rails and door edge. My cables rub and slap on the rails a bit, but after 30 years and many 10,000s of cycles, they don't seem to have worn at all.

Steel entry doors - when a garage is being fitted with new doors, it is also a good idea to consider a separate single 3x68 exterior door with half-glass and locksets too. These may require some carpentry, but they are a good way to allow for some flexibility in the choice of larger garage door, and can ensure that the homeowner will have more than a single way in or out of the structure. The average costs for such a feature range from $250 to $1000 each.
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.

If you have paired springs, you can take a shortcut here instead of using locking pliers. Simply apply a slight torsion to the bar by clamping one of the springs with an easy half-turn or so applied. This will hold the lift cables in slight tension while you wind the other spring. If you have a single spring design, you can't use this trick, and have to use the locking pliers.
"I couldn't be happier, they solved a year long problem we had that a competing company of theirs (who installed the garage on our new home) couldn't fix! I feel Ric and Randy both (who have fixed a garage at my old house and my new house) take a lot of pride in their work, they are ethical and operate with integrity. I only want to work with Precision Garage Door from now on. I'd recommend them to anyone and everyone! ”
These springs weighed in at just over 9 pounds each, including the winding cones. They are covered with a light film of oil, and at this point the job starts to get messy. The manufacturer has painted them with a "225B24" part number, which no doubt indicates the 0.2253 inch wire size, 24 inches long. Perhaps the "B" indicates the 2-inch inside diameter. Both the left- and right-hand springs have this same number on them.
