First and foremost, a garage door, by design, contains springs designed to balance your door and make it easier to lift. Those springs are under incredible amounts of tension. If a spring breaks or is improperly released, it can cause incredible and potentially fatal injuries. Keep in mind, when working on a garage door spring, it is likely that your face and head will be close to it, meaning that your most sensitive area will be in the direct path of the released spring.

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.
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.
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).
Depending on the design, you can know in advance how many turns are going to have to be unwound. Lifting a 7-foot door by winding a cable on a 4-inch diameter (about 1 foot circumference) drum requires about 7 turns, plus one extra turn to maintain cable tension at the top-of-travel. Maintaining tension at the top-of-travel is critical; without it the cable will jump off the drum, requiring a serious repair.
The standard winding tools are simply a pair of 18-inch lengths of mild steel rod, 1/2-inch diameter. Winding cones can have different socket sizes (such as 5/8 inch instead of 1/2 inch), so it is important to measure the socket and select a matching rod diameter. Also beware that poor-quality cones may have a sloppy fit to the winding bars, and a loose fit presents a severe hazard of slipping at the worst moment; anything more than about an inch or two of play at the handle end is too loose for safety. I bought a 3-foot length of zinc-plated 1/2-inch diameter steel rod from Home Depot for about $3, which conveniently cuts into two halves of just the right length (the store might even cut it for you if you ask). A steel supplier selling at commodity prices might charge about 50 cents or so for such a piece that weighs about 2 lbs. Drill rod would work if used in the annealed condition in which it is originally sold, but the added expense provides no benefit and the brittleness (if it had been hardened and not annealed) would worry me a bit. Rebar, threaded rod, screwdrivers, etc., are absolutely foolish as they will not fit the socket snugly. Aluminum rod is definitely too weak, and will bend under the torque that must be applied. Longer rods would make for more leverage but unwieldly swing; shorter rods make for uncontrollable swing. As we'll calculate below, the 18-inch standard tool length is an appropriate compromise. Note that you do not need 18 inches of ceiling clearance above the torsion shaft to use an 18-inch rod, since you need not swing the rods above horizontal when winding.
Extension spring systems should always be restrained by a safety cable that runs through the middle of the spring, tying off to a solid point at the rear and front of the horizontal door track. Extension springs represent a hazard to bystanders when a spring, pulley, or cable breaks under tension. Metal parts from extension spring systems can suddenly be launched.

Michael Davis replaced the tension springs and just about everything else that moves on both of my single car garage doors. I think I paid a premium price ($900) but I also believe I got the quality of service I paid for. Both doors are balanced and glide effortlessly and quietly along the tracks. Michael took the time to inspect and adjust every aspect of the garage door system including the opener (which I installed myself).read more

Containment cables. When old extension springs break, the springs and cables become heavy whips that damage cars and even injure people. To solve the whipping problem, manufacturers now offer containment cables that run through the center of side-mounted extension springs. If you have extension springs and don’t plan to replace your door, make sure the springs have these containment cables, or have a professional install them.
Your garage door is used often, generally more than any other door on your home. Therefore, it’s important to make sure that it’s tough, dependable and weather resistant. Our doors are fully capable of meeting all these requirements and are specifically designed with our customers in mind. While durability is important, so is appearance and we offer many different styles and colors of garage doors to match your home or business.
Security Lights: Most newer garage door openers have at least two bright light bulbs, as well as lights activated by motion. On the other hand, some older or cheaper openers are limited to a single light bulb. This doesn't help much with a garage darkened by shadows, leaving you unsure if the rustling in the corner is your cat … or a skunk that snuck into the garage.

In addition, Garaga has certified our company as one of their Garaga Expert dealers, which means we meet their strict criteria for technical expertise and professionalism.    

The first garage door opener remote controls were simple and consisted of a simple transmitter (the remote) and receiver which controlled the opener mechanism. The transmitter would transmit on a designated frequency; the receiver would listen for the radio signal, then open or close the garage, depending on the door position. The basic concept of this can be traced back to World War II. This type of system was used to detonate remote bombs. While novel at the time, the technology ran its course when garage door openers became popular. While the garage door remote control transmitter is low power and has limited range, its signal can be received by other, nearby, garage door openers. When two neighbors had garage door openers, then opening one garage door might open the neighbor’s garage door as well.

 Nate was very polite and knowledgeable about our garage door dilemma. He was prompt and earlier than the appointed time. He phoned ahead to alert us of his approximate arrival. He assessed the situation and gave us options to choose from. He educated us about our type of garage door and the opener that is typically used with it. He basically did an overall replacement of all moving parts, (spring, cables, bearings etc..). He made sure that the opener wasn’t damaged in any way from the broken spring on the garage door. He was finished within the hour. Everything works great and we are now able to get our vehicles out. When the spring breaks on your garage door, there is no way you can lift this door. It was a little expensive but at least we didn’t have to buy an entire door assembly.read more

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!
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.
Electric Garage Door Openers – Service and repair of the electric garage door opener itself, including the lift mechanism that pulls the door up and guides it down. This is typically not part of the garage door itself and is serviced and repaired on its own interval. Typical service includes inspection, repair, adjustment, and lubrication if needed. Also, we typically inspect the mounting of the unit as well as its attachment to the door itself.

The typical electric garage door opener consists of a power unit that contains the electric motor. The power unit attaches to a track. A trolley connected to an arm that attaches to the top of the garage door slides back and forth on the track, thus opening and closing the garage door. The trolley is pulled along the track by a chain, belt, or screw that turns when the motor is operated. A quick-release mechanism is attached to the trolley to allow the garage door to be disconnected from the opener for manual operation during a power failure or in case of emergency. Limit switches on the power unit control the distance the garage door opens and closes once the motor receives a signal from the remote control or wall push button to operate the door.[3]

The garage door opener traditionally has been a simple device. And it still is for the most part. But as with a lot of household items, technological advances are finding their way into garage door opener hardware. There are quite a few cool features in modern garage door openers, some of which are things you never knew you needed to automate the process of opening and closing a garage door.

Our reviewers tested a top-rated garage door opener daily for over a week. To get the most comprehensive results possible, they installed it themselves and observed how it performed. We asked our testers to consider the most important features when using this garage door opener, from its drive type to its security features. We've outlined the can’t-miss points here so that you, too, know what to look for when shopping.

Critical measurements: Torsion springs come a variety of standardized sizes, so you have to carefully measure the old springs to know what to order for proper replacements. Tables of standard sizes and designs are on the Web, such as here [www.industrialspring.com]. The four critical measurements (all in inches) are: (1) the wire thickness (which I'm measuring here with a dial caliper; you can also measure the length of a number of closely stacked turns with a ruler and divide by the number of turns in the stack, measuring 10 turns this way makes the math easy), (2) the inside diameter (not outside!) of the relaxed (not wound!) coil, (3) the overall length of the relaxed (not wound!) spring coils, not including the winding cones, and (4) the right- or left-hand winding of the spring. One must glibly quote those figures to the spring supplier, otherwise one's lack of expertise will be obvious, and one will not be worthy of buying the parts.
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.
