The winding technique is simply to (un)wind as far as one rod will go, where it is pressed against the top of the door, or nearly so, by the unwinding torsion. You insert the other rod in the next socket, remove the first rod, and continue. At any point you can stop and rest by leaving the active rod pressed against the door, where it will be held by the unwinding force. I would make a quarter-turn increment that way, and let go for a moment to collect my attention for the next increment, almost in a quiet, meditative alertness. While you can go from one quarter-turn and rod-swap to the next continually without letting go, working fast against the steady tension seemed to invite a kind of shakiness in my arms that was a bit unsettling. It isn't that there is much physical exertion, it is more that the tension is unrelenting, like peering over a precipice.

Another moment of truth arrives as the winding-up of the springs begins. (I am just posing here with the camera held out in my left hand. Except for lifting the door onto the scale, this was a one-man job, including the photography.) The position of the bars in this photo was necessary to take the photo, and does not show a correct winding technique, You should not have to swing the bar up as high over the top as shown. The lower bar during winding should swing from pointing down to pointing a little past horizontal. Then you hold that bar horizontal while socketing the other bar pointing down, apply force to that (now) lower bar, then remove the (now) upper bar, wind one-quarter turn, and repeat.
Two of the spring references specifically for the garage-door industry are the APCO Spring Manual by Bill Eichenberger, and the Torsion Spring Rate Book by Clarence Veigel; these give tables of spring sizes and torque constants. Spring engineering principles in general are described in the Handbook of Spring Design published by the Spring Manufacturer's Institute; the formulas allow you to calculate torque constants knowing only the geometry and the Young's modulus of the material. You can also find some brief spring information in standard references like Machinery's Handbook and Marks' Standard Handbook for Mechanical Engineers.
Step 1: Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. Working inside the garage with the garage door closed, examine the tracks for dents, crimps, or flat spots. If there are any damaged spots, pound them out with a rubber mallet, or with a hammer and a block of scrap wood. If the tracks are badly damaged, they should be replaced.
The door and tracks at this stage of the repair are in a minimum-energy condition. This is a good opportunity to work on any hinges, bearings, rollers, cables, or tracks that need tightening, repair, lubrication, or replacement. Again, these parts should be available from the spring source, and should be ordered based on a pre-inspection. Home-improvement stores carry some of these parts, but the type and quality may not be the best.

Install the vertical roller tracks first by wrapping the curved lip around the rollers. The top of these tracks should be approximately 8 in. below the top of the top section. Wait to install the upper tracks until this step is complete. Check the level of the top section to make sure the tops of the vertical roller tracks are level with each other. The bottom of the roller tracks should be at least 1/8 in. off the concrete floor. After leveling and mounting these tracks, install the upper roller (horizontal) tracks.
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.
Having a mismatched pair makes it difficult to specify the correct matched-pair replacements. To obtain replacement springs for a mismatched pair, you can either specify the same odd pair, try to calculate the equivalent matched pair sizes, or (this is the best method:) measure an accurate door weight and calculate the right spring size(s) "from scratch". The spring seller should be able to do the calculations from your accurate measurements of weight, height, and drum size; or you can attempt the calculations yourself using my engineering formulas below.
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.

An extension spring counterbalance system consists of a pair of stretched springs running parallel to the horizontal tracks. The springs lift the door through a system of pulleys and counterbalance cables running from the bottom corner brackets through the pulleys. When the door is raised, the springs contract, thus lifting the door as the tension is released. Typically these springs are made of 11 gauge galvanized steel, and the lengths of these springs are based on the height of the garage door in question. Their lifting weight capacity can best be identified by the color that is painted on the ends of the springs.

Cable fail-safe redundancy: Based on the proper setting of the drums on the torsion shaft, the two lift cables divide the lifting force equally to keep the door level as it rises. This not only levels the door, but also provides a fail-safe mechanism. If one of the cables should fail, such as from breaking or losing its end attachment, the other cable will then carry the full weight of the door. This will pull the door up on one side with twice the normal force, while the other side falls from its now unsupported weight, tending to make the door bind in its tracks and jam. Although not foolproof, this is a safety feature of the design which keeps the door from falling catastrophically if a cable were to fail while the door was traveling. The jammed condition also prevents a lowered door from opening with the hazard of a single broken cable, further minimizing the chances of both cables failing. Since if one cable fails the other must sustain the full weight of the door, the cables and attachments are rated many times the normal working load of half the door weight. A proper safety inspection of the door should include a critical look at the cables and their attachments.
By watching the chalk mark while winding, you can count the number of turns applied, and confirm the number later. My standard-size door (7 foot height) with 4-inch drums has a nominal wind of 7-1/4 or 7-1/2 turns, which leaves 1/4 or 1/2 turn at the top-of-travel to keep the lift cables under tension. After 7 turns on the first spring, I clamped down the set-screws, weighed the door again, and found a lift of about 100 pounds in reduced weight. As expected, this wasn't quite half of the full 238 pounds, nor would it leave any torsion at the top-of-travel, so I added an 8th turn. The door now weighed 122 pounds on one spring, which was ideal. After winding the other spring, the door lifted easily, with only a few pounds apparent weight. This confirmed that the spring choice was properly matched to the door design. I engaged the electric opener trolley, and adjusted the opener forces down to a safer level suitable for the new, improved balance. The door was now ready for return to service.

Finding the best rated garage door openers is a bit of a challenge. Quality professional reviews are currently hard to come by, and we did not spot any that addressed current models. About the only credible, current, testing-based feedback we spotted was from Wirecutter, and it addressed smart garage door controllers rather than openers. That said, if you would like to add smart features to an existing garage door opener that you are otherwise perfectly happy with, the review is worth a read.

Yet another professional wrote me to say that the red paint on certain components of these assemblies is an "industry standard" that signals, "Danger! Part under hazardous tension." Other items under tension like the bolts on the cable attachment plate on the door should therefore also be painted red. If so, then this is a new, ambiguous, unreliable, and little-publicized standard, because none of my old hardware shows it, red paint also means other things, and searching the Web does not readily turn up references to this practice.
In the United States, the Consumer Product Safety Improvement Act of 1990 required that automatic residential garage door operators manufactured on or after 1 January 1991 conform to the entrapment protection requirements of the 1988 version of ANSI/UL standard 325.[11] A requirement for redundant entrapment-prevention devices was added in 1993; such a system can use an electric eye, a door edge sensor, or any other device that provides equivalent protection by reversing the travel of the closing door if an object is detected in its path. [12][13]

Follow the manufacturer’s instructions to assemble the opener and mount the rail to the header bracket above the door. Then set the opener on a ladder where you’re going to install it. The ladder (usually an 8-footer) holds the opener in position while you measure for your lengths of angle iron. If necessary, put boards under the opener to raise it.


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.
Right-hand versus left-hand winding: Springs are chiral, that is, wound or "laid" in either a left- or right-hand orientation. This is a critical property of their design and specification; you cannot substitute a left for a right or vice versa. If you were to grasp the spring in your hand, and if your right hand orients the tips of your fingers like the ends of the coiled wire when your thumb points "out" of the core of the spring, then you have a right-hand spring; likewise left (which end you grasp does not matter). (This also happens to match the "right hand rule" of magnetic polarity, if you happen to be knowledgeable in such esoteric subjects.) Another way to identify the winding is to examine the spring vertically in front of you; if the coils facing you rise going to the right, it is right-hand (thus you can remember, "rise to the right is right-hand"), and likewise left indicates left-hand. Another way is to view the coil axially; a right-hand spring winds in a clockwise direction as it recedes away, and a left-hand spring counter-clockwise. Yet another way, not so easy to remember, is to hold the spring vertically and compare the coil shape to the letter "Z" (indicates right-hand lay) or the letter "S" (indicates left-hand lay).
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.
Garage doors cause injury and property damage (including expensive damage to the door itself) in several different ways. The most common causes of injury from garage door systems include falling doors, pinch points, improperly adjusted opener force settings and safety eyes, attempts at do-it-yourself repair without the proper knowledge or tools, and uncontrolled release of spring tension (on extension spring systems).

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.

While you may be able to increase efficiency by replacing the weather stripping at the bottom of an old garage door, the kind of insulation and energy efficient materials used in today’s new doors will make a drastic improvement on your garage’s energy efficiency. Just like the way a new garage door recoups its costs in increased home value, a new door will also quickly pay for itself in energy savings!

Most wood doors are sectional roll-up doors, though a swing-up wood door that’s meant to be painted can be affordably built in the driveway from a wood framework and plywood. Custom wood doors are typically made of durable softwoods such as Douglas fir, cedar, redwood or cypress, or from hardwoods such as oak or mahogany. Appearance-grade hardwoods are relatively expensive.
Garage doors can cost $200 for a single door and up to $4,000 for two doors or more. Keep in mind that better materials will cost more. This price also includes purchase of new tracks, adhesives, connectors and fasteners. You could install the door yourself but the weight of some garage doors are extremely heavy, so make sure you have help if you are trying DIY garage door replacement. Contact a professional or do research online to find out the average weight of different types of garage doors.

Cost was $88 for 2 pairs of springs, plus $21 shipping. (I had to order 2 pairs to meet the $50 minimum order.) They came with new cones inserted as shown at that price, so I didn't bother trying to remove and reuse the old cones to save a few dollars. The cones are quite difficult to remove from old springs and to insert in new ones, and the spring supplier will have the right tooling to do that easily. That was the best price I could find on the Web at the time, and didn't seem out of line with what parts like this might cost at at the building supply (if they only sold them). Contractors buy these much cheaper in quantities; they're just an ordinary high-carbon steel wire turned on a winding machine. I also found Web sites asking a lot more money, obviously trying to cash in on search-engine traffic from do-it-yourselfers. Others report that some local dealers sell springs at retail, but at a high price that eliminates any economy versus having them installed.
Measurements: With the door in the down position, I measure a wire size of 0.273 inches, outside diameter of 2.0 inches, and overall length of 41.5 inches. Relaxing the spring shortens the length by about 7.5 coils of wire, so to estimate the relaxed length, we deduct the wire diamter of 0.273 inches times 7.5 from the 41.5 inch wound length, yielding an estimated relaxed length of 39.5 inches. The mean coil diameter is 2.0 - 0.273, or 1.73 inches. Perhaps this was actually a 40-inch-long spring with a 1.5 ID, 1.75 mean diameter, and 2.0 OD, but let's continue on calculating with the actually observed sizes. The number of coils in the relaxed spring is the relaxed length of 39.5 inches divided by the wire size of 0.273 inches, or about 145 coils. Deducting about 5 dead coils at the ends yields 140 active coils.
One of these "sproing" events at our house finally motivated me to research how these repairs are done. This happened in 2002, when my wife parked the chariot and shut the door. After the door closed, there was a horrific noise that she could only astutely describe as, "a big spring snapping and vibrating". Although I have hired professionals several times in the past to install or repair garage doors, the difference this time was the innovation of Google and newsgroups like alt.home.repair. I was determined to learn the process and to search for online parts vendors.
If your garage door is opening slowly or making a lot of noise, the problem may not be your opener. So before you buy a new one, check for broken or wobbly rollers and brackets. But don’t replace the bottom roller bracket yourself—the cable attached to it is under extreme tension. You’ll need to call a pro. If you’re replacing the rollers, get nylon rollers. They operate quieter than steel rollers and cost only a few bucks more. Next, check the torsion spring (mounted on the header above the door opening) to see if it’s broken. When one breaks, you’ll see a gap in the coils. You’ll need a pro to replace a broken spring.

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.
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.
Leveling the door: Before commencing the spring winding, to check that you have the door properly leveled on the cables, considering all the factors above that make this a tricky adjustment, apply the winding cone setscrew lightly to lock the (unwound) spring cone temporarily on the torsion shaft, and momentarily lift the door slightly off the floor. Adjust the drum set as needed to level the door, repeating this slight lift test. Loosen the cone setscrew before winding the spring(s).
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.
The German-made, .75-horsepower (equivalent) Direct Drive 1042V004 garage door opener doesn't use a belt drive or a chain drive. Instead, the mobile motor crawls along a stationary chain, making it exceptionally quiet. This garage door opener is also feature-packed, though the wireless entry keypad is an extra-cost accessory. Reliability is excellent, and installation is at least a little easier than some other garage door openers. This opener is also sold under the Sommer brand and with different model numbers, but all are similar.

Step 2: Check the tracks with a level to make sure they're properly aligned. Horizontal tracks should slant slightly down toward the back of the garage; with roll-up doors, the vertical sections of track should be exactly plumb. Both tracks must be at the same height on the garage walls. If the tracks are not properly aligned, loosen but do not remove the screws or bolts that hold the mounting brackets, and tap the tracks carefully into position. Recheck the tracks with the level to make sure they're in the right position; then tighten the screws or bolts at the mounting brackets.

Once the springs are relaxed and loose on the torsion shaft, the lift drums lose their tension on the lift cable, and the cable comes loose. The end of the cable is terminated by a press sleeve, which locks into a ramp on the drum. Different drum styles have a bolt or other method to fix the cable end to the drum. These steel cables are springy and won't stay in place without tension. If my pre-inspection had showed that these cables were worn or frayed, then I would have ordered proper replacements ahead of time from the spring distributor, since this is the opportunity to replace them. Standard hardware-store cable and fittings are not appropriate.
The inside of the door panels bear a few dings, since filled with Bondo, from my teenage boys shooting hockey pucks. The streaks on the right that look like dinosaur claw scratches came from operating the door inadvertently when the rear doors of a van were open. The responsibility for these scars is all mine; they have also been Bondo-filled. We tend to use a lot of Bondo around our house. The crud on the walls and ceiling are cobwebs and dust infiltrates.

Good response time and service; Question - I googled to find the Sears Garage Door repair phone number. During the conversation, I was unsure if this was "Sears" or a "contractor service" or other service. I had to ask if this repair person was coming from "Sears" or an independent repair. I was concerned until the service man arrived in a sears truck wearing Sears apparel. You might want the process to be more clearly identified as Sears.
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]

Cycle lifetime unchanged by diameter-versus-length tradeoffs: Since the material stress (and thus cycle lifetime) for equal torques varies only with d, and not D or N, trading coil diameter (D) for spring length (N) in this fashion has no effect on cycle lifetime. Long and skinny, versus shorter and fatter, they'll wear the same if they have the same wire size and diameter-length product. The game of life is all about wire size when it comes to springs (see below).
