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.
Wheel Track Obstruction – Try closing the garage door manually to see if there are obstructions on the wheel tracks. If that is not the case, examine your tracks for potential damage like dents and bends. Look at your door to see if it is hanging unevenly. If the track is damaged or the door is hanging unevenly, it is time to call a professional for repairs. Track repairs can typically cost $133 to $154. Cost for correcting the uneven hanging of doors themselves can vary greatly, but typically cost about $125.
The "safety issue" trick: Another tip-off is the use of language like "safety issue". This is meant to trump any objections you might have to a costly repair bill. Don't be manipulated by the suggestion that you are risking disaster if you don't buy something expensive. Even if you think the risk is genuine, get another estimate, and tell the second repairman you are skeptical; every technician loves to prove the competition made a mistake.
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.
One might stack lumber or arrange some other low platform for a steady footing, instead of the ladder. The aluminum ladder shown here is the splendid 16-foot Krause Multimatic, which carries a Type 1A Industrial rating (300 pound working load); I highly recommend it. However, product liability apparently forced this company into bankruptcy in September 2000 and the company ceased operations in June 2001; see http://www.krauseladders.com (this Web site went dead sometime in mid-2002). The world is a dangerous place.
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).
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.

Even if one could somehow stretch and clamp the springs to the proper extra length, the process would still be more trouble, and there would be little or no reduction of risk. Lifting the full weight of the unsprung door by hand and clamping it in the raised position is dangerous in itself, and creates the same amount of stored energy as winding the springs, ready to slip out of your hands. Many doors won't travel far enough up the track to provide clearance to access the springs. You're also going to have to deal with winding stiff steel cables onto both lift drums at once without any resistance to maintain tension. Finally, even if you managed to complete the installation with the door raised, you then have to lower the massive door against an untested balancing torque. If you've made a mistake, then that massive door has nothing but your skeletal force applied through your meat clamps (hands) to prevent it from falling down and crushing whatever is in the way (perhaps your feet?).
Given the complexity of a garage door and opener system, there are a variety of different areas something could go wrong. If your garage door shakes or is very loud during operation, the garage door closes all the way only to immediately open back up, the garage door opens slowly or closes too quickly, or the garage door opener and remote aren't working at all, you should seek help from a professional garage door repair specialist.
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.
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).
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.
Most styles, whether traditional or contemporary, feature panels, trim, and other detailing. Doors with true frame-and-panel construction tend to be sturdier than those with decorative detail that is merely glued or nailed on. Many styles have glass panels on the top row, which looks inviting from the street and brings daylight inside. You can also find roll-up doors with shatterproof glass or frosted plastic in all the panels, for a more modern look.
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.
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.
Insulation increases the efficiency of your door and can lower your electric will. You need R-value garage doors. These type of doors keep out hot and cold air and also provide a sound barrier between the outside and your garage. Insulated doors use polyurethane or polystyrene foam as insulation inside the door.

Not only was the upward-lifting garage door and the electric garage door opener invented by Overhead Door Corporation’s founder C.G Johnson in the 1920s, but we also have a tradition in excellence for garage door repair, service and maintenance. Even with the most reliable products problems can arise and when they do it’s important to know who to contact to fix these issues while providing solutions to prevent future complications.


Horsepower is another key factor when it comes to garage door openers. Look into ½ horsepower garage openers if you have standard aluminum doors. Oversized doors and one-piece doors may require 3/4, 1 or 1¼ horsepower garage door openers. Garage openers with higher horsepower use less effort to operate and minimize wear and tear on the motor. This is ideal if your garage doors act as the main entrance to your home.

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.
Note the left winding cone with red spray paint. This shpritz of paint is applied to create fear and doubt in the mind of the do-it-yourselfer. Sometimes it is a color code for the wire size (using a DASMA standard, red indicating 0.2253 inch diameter wire). Sometimes it indicates the winding direction: red may indicate right-hand winding, but don't rely on that; do you own independent analysis. Sometimes it is a manufacturer's private code for another dimension than wire size. This color code is for the installer's information when the spring is new; I would not depend on interpreting the color code properly on an old spring, since one can't be certain of a correct interpretation without documentation from the original supplier.
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.
Your garage door is most likely the largest opening on your home, and as a result, it can affect your home’s energy efficiency. For homes in areas that experience colder winters or warmer summers, choosing an insulated door can save you money and improve the comfort of your home. Doors insulated with our Intellicore® insulation technology operate more quietly and are more durable. We also offer insulated glass window options that can help maintain energy efficiency and allow natural light into your garage. Visit our insulation guide to learn more about garage door insulation, or learn more about Intellicore® here.

Great service all around! Friday night issue with other service company… Aaron’s didn’t turn me down in resolving the fact that I had NO use of my door until Monday. They sent a very well experienced technician on Saturday morning. He was prompt, explained everything very well, advised on next service needs (without being sales-y) and did an awesome job! Thanks again!!!
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.

All measurements should be in feet and inches. Step 1, measure across the existing door or desired space for the width, then up and down for the height. The rough opening of your space should be the same size as the door. Step 2, measure the sideroom, which is the space beside your door. Measure the width of the left side, and then the width of the right side. Step 3, measure the space above the door, which is called the headroom. Measure the height of the distance between the top of the door opening and the ceiling. Step 4, measure the ceiling, which is called the backroom. You’ll need to measure the distance of the garage door opening toward the back wall of your garage. You should have 6 total measurements in all once you’ve finished measuring the space. Keep in mind that having an automatic garage door opener installed might call for additional backroom or ceiling space.


Great!  We specialize in all sorts of garage door repair work.  Working around the garage door can be fairly dangerous if you’re trying to repair this issue on your own.  Most garage door companies will quickly remind folks about this, and it’s true.  Their are some hazards to watch out for when working around these heavy and high tension doors.  We recommend you give an expert a call to address the issue in a safe and timely manner for you.

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.


Garage door openers manufactured and installed in the United States since 1982 are required to provide a quick-release mechanism on the trolley that allows for the garage door to be disconnected from the garage door opener in the event of entrapment. [8] Garage door openers manufactured since 1982 are also required to reverse the garage door if it strikes a solid object.[9][10]

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.

The deluxe-model upsell trick: Don't you want the best? Don't you want to protect your family? Galvanized springs may be offered to you at extra expense as "longer lasting". Although bare springs (also called "oil tempered") can develop a light film of rust, the eventual failure is due to fatigue and not corrosion. The use of coated springs (whether galvanized, painted, powder-coated, or surface-converted) is mostly about appearance: the customer likes his new door to look shiny, and the customer doesn't like repair parts that show superficial rust from storage.

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
Sterling Door is the only company we trust with our garage door. When our old door acted up, springs, track, etc., they were always timely and got the job done. Then when we made the jump to a new door, they were excellent. They helped us choose the right door, not just pushing the most expensive model. And installation was well done. I recommend Sterling Door for all of your garage door needs.
Reduce your monthly energy bill with insulated garage doors. They feature an insulated core made of polystyrene that’s surrounded by a steel cover. This can help you maintain the temperature inside your home no matter if it’s extremely hot or cold outdoors. Insulated garage doors are also known for their quiet operation. Be sure to look at the insulation rating – or R-value – when considering garage doors. The higher the R-value, the better the insulation.
I backed into my garage door, then my husband tried his hand at fixing it...which only made it worse. The door wouldn't go down and we were leaving town the next day. I called at 9 am on a aturday morning, and Tom called to say he'd be there between 9:45 and 10! He got there just before 10 am and fixed the door in less than 30 minutes. He was very fast, efficient, and knowledgeable. The price was lots lower than I thought it would be. All in all, we were very pleased with the service.
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.
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.

Manufacturers and distributors of torsion springs believe they are better off not retailing their product directly to the public. They believe they are maintaining higher prices for their product by restricting sales "to the trade." One brochure for parts even flatly stated, "We do not sell to the end user. We protect our dealers," which would seem to be prima facie evidence of an illegal restraint-of-trade scheme. But this is an old story which is true of virtually every product and service, going back to medieval guilds and before.
Although the door weight and drum size determine the maximum torque (termed MIP, maximum inch-pounds) needed from the fully-wound spring(s), the spring selection for a given door can still be varied to adjust the cycling stresses. A heavier wire on a larger diameter or longer length will produce the same torque as a lighter wire on a smaller diameter or shorter length, while undergoing less stress and therefore increasing expected cycle lifetime. The heavier spring will cost more but last longer, so this is another design trade-off. Calculating these spring sizes in the field is done using a book of tables (or the software equivalent) that we cannot provide here, although you will find the formulas to estimate spring properties below. If you can accurately provide the weight of the door, or the size(s) of the old spring(s) (assuming they were well-matched to balance the door), then a spring dealer should be able to tell you which spring sizes will work for you.
Spring rate and torque: In my spring replacement above, the wire size was d = 0.2253 inches, and the ID was 2 inches, giving a mean diameter D = 2.2253 inches. The number of coils is L/d = 24 inches / 0.2253 = 107, less about 5 dead coils on the winding cones, or 102 active coils. Thus the spring rate is K = (π*28.5*10^6 * (0.2253)^4) / (32 * 102 * 2.2253) = 31.8 in-lb/turn (IPPT). Winding 7.5 turns * 31.8 in-lb/turn yields a torque of 238 in-lbs per spring.

Wood doors range from midprice to very expensive, depending on whether they consist of a lightweight wooden frame filled with foam insulation and wrapped in a plywood or hardboard skin (the least expensive) or are true frame-and-panel doors made of durable mahogany, redwood, or cedar. Wood doors usually carry a short warranty, perhaps only one year. 
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.

Finally, one of the most important garage door innovations over the years in increased child safety features. Sensors can detect when a child or pet is crossing the threshold while the door is closing, prompting it to stop immediately. Furthermore, doors can also sense when something is being pressed by the door, causing it to stop before inflicting a brutal crushing injury.
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.

Repair Sagging Garage Doors – As doors and homes age, they can shift and move and sometimes this results in a garage door that needs to be realigned or reinforced. We will send a technician to your home to adjust the doors and to inspect the entire opening to make sure the door isn’t damaged. Once we understand the problem, we will fix the needed parts and make any adjustments to the door.
Screw - Screw-driven lift systems attach a long screw to the motor to move the garage door. These systems are powerful, fast, relatively quiet and require less maintenance than typical chain- or belt-driven systems. Genie and Overhead Door are two popular brands that make screw-driven systems. Based on our research of Genie’s line, you can expect to pay $244 on average for a screw-driven garage door opener.
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.

Resetting the drums, if needed: If the drums were incorrectly set in their old positions, one must reset both drums in new positions on the shaft. This is complicated by the presence of old dimples in the torsion shaft from previous setting(s), which must be avoided lest they improperly influence the new setting of the drums. To begin this process of resetting the drums, the door must first be lowered and resting level on the floor, the spring(s) must be in the unwound condition with their set-screws loosened, and the lift cables wrapped around the drums. If for some reason the door does not rest level on the floor, such as the floor being uneven, then insert temporary shims between the door bottom and the floor to bring the door up to level. Loosen the set-screws on the drums, and turn the torsion shaft to avoid the old dimples from the set-screws in the old drum position. Tighten the set-screw on the left drum (that is, on your left as you face the door from in the garage), creating a new dimple, and apply tension to its cable with the locking-pliers technique, enough tension to keep the cable taut but not enough to start to move the door up. Attach and wind the cable on the opposite (right) drum by hand until the cable is similarly taut, and set the screw, remembering that tightening the screw will tend to add a bit of extra tension to the cable. Both drums should now be fixed on the torsion shaft, with the cables about equally taut (listen to the sound when you pluck them like a guitar string) and the door still level on the ground. Setting the left drum first, and the right drum second, will allow you to take up any slack in the cable introduced by the left drum rotating slightly with respect to the torsion shaft as you tighten the set screws. This alignment and balance of the cables, drums, and door is critical to smooth operation and proper closing. If you have a single-spring assembly, the distance along the torsion tube from the spring cone to one drum is longer than to the other drum, which allows a bit more twist to one side than the other, and you may have to compensate with the setting of the drums.


You'll never ask yourself that question again. Just look at your phone to know for sure. Most smart garage door openers will tell you if it's open or shut. They'll send a message every time your garage door is opened or closed too, if you like. Electric garage door openers provide a huge amount of convenience and safety. Imagine you're in a hurry, it's raining out, you pull out of the garage then press the button on your garage door opener remote. The garage door closes, and you didn't have to get out of your car.
