You might be thinking: Aha! Why don't we lift the door, clamp it in place, and install the springs while they are thus safely unwound, rather than deal with all that accumulation of hazardous torque? The answer: At the top-of-travel, the unwound springs are not fully relaxed; they are still clamped to the torsion shaft with a significant stretch along the shaft axis, plus about a half-turn to keep the door snug at the top. This extra length amounts to the stacking of extra turns that accumulate from winding, also termed "spring growth" in the business. In my case this is about 7 turns of 0.2253 wire, or about 2 inches. Stretching the spring that much and clamping it with a half-turn or so of twist is not feasible.
When buying an opener, choose a 1/3 hp or 1/2 hp opener for a single garage door (1/3 hp can be hard to find at some home centers). Go with 1/2 hp for a double door and 3/4 hp for a door that has a wood or faux wood overlay (they can be heavy!). Openers have a set opening speed, so installing an opener with a higher horsepower won’t open your door any faster.

Screw-drive garage door openers are another type of direct-drive garage door opener. The screw-drive's relatively simple mechanism, which moves up and down a threaded steel rod, makes for a powerful, low-maintenance garage door opener. They are quieter than chain-drive openers, and are fast workers, but, like direct-drive openers, they tend to be pricey.
In my case, removing and replacing the relaxed springs required that I take down the assembly: torsion shaft, lift drums, and bearings. Doing that requires unbolting the center bearing plate from the wall, removing the drums from the shaft, and finally sliding the shaft back and forth out of the end bearings to remove the whole assembly off the wall. I am fortunate to have a lot of clearance in this garage to make the disassembly simpler. Tighter clearance to walls or ceiling would make disassembly a more difficult manipulation.
Most electric garage door openers have two lights: one in front of the opener and one behind or sometimes they sit side by side. They should provide enough light for you to get into your home from your car. Generally, people don’t leave the garage light on when it’s not in use, so it’s nice to have a temporary light when you arrive home. The length of time the light stays on varies according to how it is programmed. In most instances, you don’t need more than a few minutes from the time you leave the car to when you enter your home.
At this point I weighed the unlifted door to confirm and fine-tune my calculations. This is not strictly necessary, but it makes the adjustments easier to perform, if you happen to have a scale with the requisite capacity. With some helpers, we first lifted the door a few inches and rested it on blocks of wood to provide clearance underneath. Then I slid a 400-pound-capacity freight scale under the center of the door, we lifted again to remove the blocks, and lowered the door gently onto the scale. This door weighed in at 238 pounds, which is very heavy for a single-car door. Since the outside of the door carries the 3/4-inch plywood paneling to match the house, and that plywood weighs about 2 lbs/sq-ft, I estimate the door weight to be about 7 x 10 x 2 = 140 lbs of paneling with the rest 238 - 140 = 98 lbs the interior panels, hardware, and cobwebs. Knowing this total weight will help later in adjusting the torsion on the springs. After weighing, we removed the scale and blocks, leaving the door fully lowered again. Had I not had a high-capacity freight scale, I might have improvised a crude weighing device from levers and smaller weights of known mass, or a lever arm pressing a reduced proportion of the full weight onto a lower-capacity scale. Another factor to remember is that The weight of a wood door can vary with humidity.
R-value describes the power of the insulation in your door. The higher the r-value, the stronger the insulation. Those doors will have better energy efficiency than doors that have a low r-value. Basic doors have an r-value of 0.0 with no insulation. The first step up gives you 1-3/8” insulation at a 6.5 rating. Next, a 1-3/8” thickness with Intellicore has a 12.9 r-value. The best option on the market is the 18.4 r-value, which has 2” Intellicore insulation.

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.
The most common problem with garage door openers is the door reversing when it’s closing, even when there’s nothing obvious obscuring the photoelectric eyes. If your closing force is adjusted correctly, then the problem is almost always the photoelectric eyes. The eyes are very sensitive— even cobwebs can interfere with them. First make sure the eyes are still in alignment (some- thing may have knocked them out of whack). Then make sure the eyes are clean and the path between them is clear. Finally, look for loose wires in the eyes and the opener.
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
Customers who have purchased this garage door opener for their homes have been mostly satisfied with the performance of it. Many have raved about how quiet it actually is—one said instead of hearing the metal squeak and clank like with their last one, only the sound of the “wooden door being jostled around as it is pulled up and down” is all you hear with this one. Customers were also happy with the features including the automatic closer when you forget to shut it after you go inside. Some had had issues with the manual being hard to understand while installing it themselves. But most were happy with the overall performance.
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.
Lower the door and dismantle it by removing the hardware. Lower a double door by recruiting at least two helpers to help with the weight, and place a 2×4 block under the door to prevent smashing a foot or finger when it’s lowered. Remove the sections one at a time by disconnecting the rollers and brackets. If you have windows, tape them to help control flying shards if they break. Then remove the old roller tracks and remaining hardware.
Some of the best garage door openers offer special features like a backup power source or a timer that automatically closes the door behind you at a predetermined time. While the door openers we reviewed vary in terms of power, noise and efficiency, they are all effective in the all-important task of letting you come and go with the simple push of a button. Here are the criteria we used to rank the top garage door openers:
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.
Fiberglass and vinyl garage doors are composite units, combining a steel core behind a fiberglass or vinyl skin. They have also polyurethane insulated base sections, or other type of foam insulation. These premium doors can match steel garage doors, and be a realistic imitation of wood (namely fiberglass units), but they may be more expensive than steel units.
While a new coat of paint can go a long way in improving the look of your garage door, the truth is that door design has come a long way in the years since garages were first installed in homes. Not only are newer doors more in line with current fashion trends, but they are also better sized for today’s cars. A new, contemporary door is a great way to get an immediate boost on the value of your home.
You must use springs that are matched to the weight of the door. You cannot compensate for the wrong size spring by adjusting the number of winding turns. If you do not know a proper spring size, then you or your spring supplier must calculate a proper size (see below) based on an accurate weight (within 5 pounds) of the door. So you must then in turn have an accurate weight.

Insulation, which increases energy efficiency and can help to lower utility bills, is crucial when a garage door is attached to the home. In this case, doors with high R-values are preferred. This means it has insulation that can keep the heat in. The higher the R-value, the better insulated your garage will be against outside noise and cold and hot air.
“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.
Good customer service is important for any product, but it is especially important for the class of garage door openers we considered. We looked primarily at models designed to be installed by a homeowner, not a professional. Even if you consider yourself to be pretty handy, you are sure to have questions at some point along the way. As such, we looked for companies that respond to all inquiries as well as for resources, such as a downloadable manual, to help with installation.
Weight and cost: The 24-inch-long spring has a calculated weight of 8.4 lbs, not counting the winding cones. At less than $1/lb wholesale, and $3/lb retail for fabricated steel products, this spring should sell for about $8 to $25 (2005 prices) each, depending on the market and source. Since a pair is required, the expected cost for a pair is $16 to $50.
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.
