The wire size and winding direction are easily discovered and proved, as I will explain below. You absolutely must know and understand the critical measurements of your old springs to order replacements. This assumes that the old springs were the correct to begin with; it is not uncommon to have incorrectly sized springs on a door due to a previous sloppy installation, or a significant change in weight of the door.
The belt-driven Chamberlain B970 garage door opener is powerful and well-featured. With a 1.25 HPS motor, it's got all of the strength needed for just about any residential garage door, and the motor and belt are covered by a lifetime warranty. The feature line-up includes built-in Internet connectivity for those who want to be able to monitor and operate their opener from afar, and a battery back up in the case of a power outage.
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
Removing winding cones from an old broken spring for reuse in a new spring: Springs without the winding cones installed are a little cheaper than with the cones. Twisting the old cones into a new spring is easy with a vise and pipe wrench, but it can be tricky removing old cones from a broken spring for reuse. To remove old cones, mount the cone in a vise such that the spring portion is free. Grab the last few turns of the spring in a pipe wrench, engaging the teeth of the wrench into the end of the spring wire. Turn the wrench against the end of the spring wire, releasing the end of the spring from its clamping onto the cone, as you twist the loosened spring off the cone. Another more certain if not brutal method is to use an angle grinder with a thin metal-cutting disk to cut through the loops of spring wire where the loops wrap around the cones, being careful not to nick the cone itself too much. You could also cut into the old spring loops with a just hacksaw and break off the loops with hand tools, but this will require a lot of effort.
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.
The chain-driven Chamberlain C410's .5-horsepower motor has enough power to handle most residential garage doors. Owners say it lifts even heavy doors easily. While chain-driven openers generally are louder than belt-driven models, most say that, like its predecessor model, it's actually pretty good in that regard, and we saw fewer complaints about installation challenges, too. The opener is also well-equipped in the feature department, though you'll need to spend a bit extra if you want to use its smart functions.

I called late on a Monday and was able to get scheduled for 8:00 Tuesday morning. Matt arrived promptly on time and did a thorough assessment of the problem. He explained all my repair options and the advantages of each. I took his advice and opted for the door overhaul, in addition to the logic board replacement. The door was the original and had been installed improperly. There were wrong parts and incorrect assembly. Matt worked diligently to make things right. What was normally a two hour job took four, as he wouldn’t be satisfied with anything less than perfection. He stopped back by late in the afternoon to make sure all adjustments were made correctly. Excellent service, fair price, and explanations of every step in the repair process.read more

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.
Unmatched or mismatched spring pair: You may find that you have a pair of springs that are different sizes. This mismatch may be a normal application, since the total torque on the torsion shaft is simply the sum of the torque contribution of each spring (indeed, very large doors can be lifted with 4 or more springs along the torsion shaft). The sum of the torque rates determine the lift; and dividing the torque among multiple springs does not change this. Some repair shops even apply mismatched pairs deliberately, since a few stock sizes of springs can be combined to fit a wider range of door weights than only matched pairs. For example, a technician may carry springs in increments of 20 lbs of lift, and when using pairs this allows a 20 lb increment in possible choices instead of 40 lb increments. Or, one spring from a pair may have broken and been replaced with a spring of equal torque rate but different size than the original.
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.
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.
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.
Spring stretch: When the door is at the top of travel, the spring(s) are hardly wound, but are stretched, so on a single-spring installation this stretch tends to pull the shaft towards the non-spring side. With two springs, the stretch tends to cancel out. This top-of-travel spring stretch, being about 7 or 8 turns of the wire, will thus amount to upwards of about 2 inches on a typical size spring of 0.253 wire. This spreads out to a gap of about 0.020" per coil on a typical 100-coil spring, so the stretch is not very visible.

I could not be happier with the service from Precision, and Tom, especially. About a year and a half ago I called to have my garage door that was sticking, repaired. Tom came out same day and replaced, adjusted, serviced all moving parts and got it going smoothly. He has since come out within hours of a call to adjust and keep (what might not be the best) door, (originally installed by someone else), operating well. I recommend Precision and Tom with complete confidence.
Ryan came to my rescue within 6 hrs of my call. He was professional, knowledgeable, friendly, and very thorough. He got my door up and running after figuring out what 3 others could not! Don’t try and go the cheapest route like I did because you’ll end up wasting time and money. Hire the pros like Ryan FIRST! If I ever need someone in the future, I’ll be calling them first thing!

How many times a day do you open or close your garage door? You probably don’t even know because we take our garage door for granted until…. Until it doesn’t go up… until it doesn’t come down… until it gets noisy, difficult to open by hand or some other problem develops. You need help – and if you’re locked in or locked out, you need help in a hurry. You need A-Authentic Garage Doors. Here’s why:

My garage door broke on a Saturday night as I was getting ready to leave for a holiday party. Kelvin was here within 30 minutes. He reviewed everything with me that was happening with my door. He gave me the estimates of what was immediately needed to be done in order for my door to raise and then what I will need to have done very soon. I could see all the problems he pointed out to me and I decided to have everything done. He completed everything that night. I was very satisfied with Kelvin’s professionalism and the work he did. Thank you again.
But the insulation won’t save energy unless you heat the garage or treat your attached garage as part of the “conditioned” part of your house. The federal Energy Star program recommends against doing this if you park cars, store lawn chemicals, or use solvents there because it could let dangerous fumes inside; it’s better to insulate only the shared wall and use that as the indoor-outdoor boundary.

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.
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.

As noted above, set-screw clamping may have distorted the cross-section of the shaft and made it difficult to slide off all the hardware. With the shaft on the floor, it may be possible to restore enough roundness to proceed, using compensating clamping force to the distorted area via a machinist's vise, an arbor press, a hydraulic shop press, etc., on the shaft body. Burrs and other slight distortions on the shaft can be filed off with a hand file or touched with an abrasive wheel on an angle grinder. At some point, the condition of the shaft may just be degraded enough that it ought to be replaced.
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.
To estimate the maximum physical force required to wind these springs, consider that they are balancing the weight of the door with a torque applied to a lift drum on each end of the torsion shaft. The lift drums have a 2-inch radius, which is the standard residential size, and corresponds conveniently to about a 1-foot circumference. If we pessimistically assume the 10-by-7-foot door has a weight of 350 pounds, this implies a torque of 350 pounds on a 2-inch radius, that is, 700 inch-pounds, or 58 foot-pounds. Each of the two springs should be exerting slightly less than half of the balancing torque, or 29 foot-pounds. Compare this to, say, the bolts in an automobile, which are typically torqued to values of about 50 foot-pounds, or tire lug nuts, which may be torqued to well over 100 foot-pounds.
We would definitely recommend Precision to anyone that needs garage door services! We were able to get a service appointment right away! Tom arrived and was very professional and courteous. He took the time to go over what repairs were needed and provided an estimate. He was ready to do the repairs right then and there and within a few hours, we had our garage door up and running like new! Thanks to Tom and Precision for a positive experience!
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.

I was very pleased with the technicians professional demeanor, the advance call, and the promptness of service. I could have done the work myself, but I feel very comfortable with the repair, and due to a recent injury it was just better for me not to climb a ladder. It was money well spent, and the old adage "You get what you pay for" certainly was true in this case.

Due to the intricacy of garage door systems, only garage service professionals should attempt to adjust, repair, or service door equipment.

As in an elevator, the electric motor does not provide most of the power to move a heavy garage door. Instead, most of door's weight is offset by the counterbalance springs attached to the door. (Even manually operated garage doors have counterbalances; otherwise they would be too heavy for a person to open or close them.) In a typical design, torsion springs apply torque to a shaft, and that shaft applies a force to the garage door via steel counterbalance cables. The electric opener provides only a small amount of force to control how far the door opens and closes. In most cases, the garage door opener also holds the door closed in place of a lock.

“This is not a simple thing to install,” cautioned one of our testers. “It's likely that you’ll make a few trips to the hardware store even if you’re very handy and have a relatively complete set of tools.” That said, our reviewers thought that this opener’s instructions themselves were very clear and that once setup was complete, the device “worked without lots of fiddling.” Another plus was its added security features, like keyless entry and smartphone app integration. Lastly, our testers did wish it had a built-in camera to allow surveillance in the garage at all times.

We’ve been reviewing the best garage door openers for more than half a decade. This year we chose the Chamberlain Premium as our top pick. It’s an efficient, reliable garage door opener, and it comes with a backup battery system that works in a power outage. This model also has a preinstalled timer that closes your garage door automatically so you don't have to worry about whether you left the garage door open.
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.
Additionally, the B970 includes encryption features that prevent others from hacking the system to gain entry to your garage. Expert reviewers like this garage door opener a lot. The Tool Spy says the Chamberlain B970 justifies its higher price point by delivering excellent build quality and anti-vibration features. Consumer Search and Garage How To also approve of this unit.
Regardless of the material, you will likely need to perform some regular maintenance tasks. A garage door professional can examine common problem areas to ensure all are working as they should. Additionally, it is necessary to examine the integrity of the door itself, since your garage can be especially vulnerable to security issues if your door is not structurally sound.

Once you’ve decided it’s time to replace your garage door — whether the result of malfunctions or just seeking to modernize your home’s exteriors — you may be wondering how much a garage door replacement costs. While these numbers are often determined by several factors, including the materials and labor involved, on average, a garage door replacement can cost just over $1,000 but could range from about $300 to over $2,000.
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.

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.
Roberto was very courteous and explained the details of what he was doing. He also pointed out a repair I might consider having done (replacement of the bottom panel of my door) and asked the office to follow up with me on this. Someone did follow up with me and since replacement of the bottom panel is not an option and I would have to replace the door, I decided that I can wait.
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.
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.

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.
Mechanical garage door openers can pull or push a garage door with enough force to injure or kill people and pets if they become trapped. All modern openers are equipped with “force settings” that make the door reverse if it encounters too much resistance while closing or opening. Any garage door opener sold in the United States after 1992 requires safety eyes—sensors that prevent the door from closing if obstructed. Force settings should cause a door to stop or reverse on encountering more than approximately 20 lbs (9.07 kg) of resistance. Safety eyes should be installed a maximum of six inches above the ground. Many garage door injuries, and nearly all garage door related property damage, can be avoided by following these precautions.
