Horsepower You’ll also want to consider the horsepower of your opener. Typically, 1/2 horsepower will work for most doors in newer homes. If you have a heavier solid wood door, though, you may want to opt for 3/4 horsepower so it can lift it with ease. You can also get 1 and 1 1/2 horsepower models, but those are a better fit for commercial or special situations.
Recently another type of opener, known as the jackshaft opener, has become more popular. This style of opener was used frequently on commercial doors but in recent years has been adapted for residential use. This style of opener consists of a motor that attaches to the side of the torsion rod and moves the door up and down by simply spinning the rod. These openers need a few extra components to function safely for residential use. These include a cable tension monitor, to detect when a cable is broken, and a separate locking mechanism to lock the door when it is fully closed. These have the advantage that they free up ceiling space that an ordinary opener and rail would occupy. These also have the disadvantage that the door must have a torsion rod to attach the motor to.
Openers are available with a chain drive, screw drive or belt drive. Chain drives (a long chain pulls the door open and closed) are the least expensive, but they’re loud. Screw drives (a long threaded rod drives a mechanism that opens and closes the door) are priced in the mid- range. They require the least maintenance, but they’re not as quiet as belt drives. Belt drives (a rubber belt opens and closes the door) are the quietest, making them the best choice if you have living space above the garage. They’re also the most expensive.

Traditional One Panel: These doors consist of one large panel which tilts to open by employing a spring mechanism to swing upward. The wood version is popular in the South and Southeastern US, where a milder climate keeps the wood from rapidly deteriorating. Traditional garage door designs include Cape, Colonial, Ranch, Tudor and Craftsman. The disadvantage is these doors require a lot of clearance to operate correctly. Sometimes repairs can be difficult because of the heaviness of the door or its inaccessibility. Average cost to repair tilt-up doors is $172.

“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.
The special-price don't-tell-my-boss trick: In this scheme, after the technician has worked on your door for a bit, he will grimly notify you that he has discovered an additional repair needed, not just the spring(s). He will offer to do the work at a "special price" if you agree not to tell his boss. This air of conspiracy to get a bargain distracts and disarms you from critically thinking whether you really needed the repair in the first place (likely you don't), and whether the price is really a bargain (likely it isn't).

Dodging a falling door:: Reversing this equation gives us x=gt^2/2 as the fallen distance x for a given time t. How much time would you have to dodge a falling door if the spring were to suddenly break at the top of travel? Let us assume you are 5.5 feet tall, so the door will hit your head after falling 2 feet from its 7.5 foot fully-raised height. This 2-foot fall takes sqrt(2*2/32.2) = 0.35 seconds (350 milliseconds). The quickest human response time is about 200 milliseconds, so even if you are alert to the hazard, this leaves you only about 150 milliseconds to accelerate and move your noggin out of the way. If you are an Olympic gold medalist in the 100 meter dash, you can accelerate (horizontally) about 10 feet/second^2, and your 150 milliseconds of wide-eyed panic will move you all of 10*0.15^2/2 = 0.11 foot = 1.35 inch.
Spending your whole weekend setting up a new garage door opener is not on the top of most peoples list. This opener is easy to install for most levels of DIYers and it provides a quiet and reliable open and close. This has 3/4 HPc DC chain features and the powerhead can open 12" in a second. It has a wireless remote and Intellicode 2 security to prevent people from breaking into your home. 

See the Sectional Overhead Garage Door catalog (PDF file) from the Prime-Line replacement hardware company. Their brochure Sectional Garage Door Torsion Spring Installation Instructions (PDF file, part number GD-12280) is brief but informative. Apparently you can only obtain their torsion springs as special order items through mom-and-pop type hardware stores like Ace and True Value, and not the big-box Home Depot and Lowes.

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.

With the rods and other tools at hand, I am ready to begin. The first task is to remove the broken spring and its unbroken mate from the torsion shaft. To remove and disassemble the shaft and lift drums, the torsion on the unbroken spring must first be released. I used a ratcheting box-end wrench to loosen the set-screws while pushing the rod against the force I knew would be released when the screws let go. Later I switched to an open-end wrench for the set-screws, since some of the square screw heads were too rough to fit in the box-end wrench.
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.
The replacement springs in my case proved to be 0.2253 wire size, 2.0 inch (inside) diameter, and 24 inches long, in a pair of one left- and one right-hand winding. Actually, the old springs in these pictures were a slightly smaller size, but another similar door on this garage was better balanced by that size. Whoever installed the old springs didn't quite get the weight and size just right; it is not unusual to find a repair service installing a slightly off-balance spring size that happened to already be on the truck during the service call. My electric opener had no trouble handling the small imbalance. But since it is safer to reduce the electric operating force as much as possible through careful balancing, I chose the size that was working better on the other door. The Chamberlain brand electric openers (also sold by Sears) I have incorporate a plastic worm gear that tends to wear out after some years of use, requiring a disassembly and installation of a $20 repair kit; this wear is minimized by a properly balanced door.

And for some extra features, you'll appreciate accessing the system through the MyQ smartphone app. You can set up this Chamberlain opener to automatically close the door after 1, 5, or 10 minutes, which is great for people who are a bit forgetful. We also really like the motion-detecting control panel, which turns on lights whenever it records nearby movement.
Center and level the first section after you install the brackets. The door must be level even if the floor isn’t, so use shims under the section to level it. The rubber gasket on the bottom section will fill the gaps created by an unlevel floor. To hold the level in place, tape it to the section. To hold the section in place, lightly toenail a 16d nail into the frame and bend it over the section. Add brackets and rollers before setting them in place and stack one section on top of another, toenailing as you go up.
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.
Direct Drive - Unlike chain- and belt-driven systems, where the motor remains stationary while moving a chain, a direct drive motor moves while the chain stays in place. Because of this, the only moving part is the gear the motor uses to move while lifting the door. To our knowledge, only one company makes direct drive garage door openers: Sommer. The company claims the motors are more efficient and quieter than any other type of opener. However, this is the most expensive type of opener we’ve found, costing around $286 on average.
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.
Technician Mark called 1/2 hr before coming. Very knowledgeable and friendly technician. Originally scheduled as a tune-up but after pointing out several potential problems I decided on the complete overhaul package. All parts were on the truck. Technician completed job in a little over an hour. Very satisfied. Definitely would recommend.Bob PNorth Myrtle Beachread more
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.
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).

If you've been helped by this Web page, as many have, all I would ask is that you create a link to this page (http://www.truetex.com/garage.htm) from any pages you maintain. You will thereby help others searching for complete and reliable information on this type of repair to find it with a Web search.
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.
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.

With good looks, modest cost, and solid return on your investment, a new garage door is the Triple Crown of curb appeal projects. According to the “Remodeling Impact Report” from the NATIONAL ASSOCIATION OF REALTORS®, the national median cost of a garage door replacement project is $2,300 and recovers 87% of your investment if you sell your house — one of the highest percentage of recovered costs in the “Report.” 

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.

Angle iron provides a stronger installation and reduces vibration, which helps extend the opener’s life span. In an unfinished garage, attach the angle iron directly to the face of a joist with 1-in. lag screws. For finished ceilings, attach angle iron along the bottom of a joist with 3-in. lag screws. Hang the opener using two more lengths of angle iron and nuts and bolts. Use lock washers or thread-locking adhesive to keep vibration from loosening the nuts.

We lead busy and sometimes hectic lives. It's easy for someone low on sleep and high on stress to accidently bump into their garage door leaving a little damage. If you're lucky it's just an individual garage door panel that's been damaged. This will leave you with the option of garage door panel replacment. There's a chance it might cost you upwards of $150-200 to spot repair damaged garage door panel. If it happens to be an in-production model, they probably will be able to repair or replace the entire panel (if needed) for $250-400. Unfortunately if you've got an older model of garage door the panels may no longer be in production. This might seem like a disadvantage because you'll end up having to just replace the entire door. Many times it's actually easier and more cost effective to just replace the garage door.

Garage doors provide one of the major entryways into your home. Therefore, it is essential to ensure that they are secure and in good working order. If you are having problems with your current door, then you need to have a professional determine if it can be repaired or if it will need to be replaced. Here are some of the most common factors that will affect the cost of a garage door repair.
Tom was professional, knowledgeable, and very friendly. He arrived at my house within the time frame he said he would (nothing is worse than a late technician). Once he arrived, he assessed the problem, explained it clearly and concisely, and informed me he had the parts available with him to fix it. He fixed the issues speedily and I was able to return to work within the hour. The price was reasonable too. I would recommend Precision to any of my friends and neighbors. Thanks Tom!

It you have a tilt-up door, you are looking at a $150 - $200 repair or replacement. If it's a roll-up door it's going to cost you more. Roll-up door spring repair or replacement is usually around $200 - $250 for a 2 car door. If the brackets need to be disassembled to remove the springs due to the shaft not sliding sideways enough it will cost you an additional $50 - $100.

Most doors come with electric door openers. After a while these openers malfunction and need to be replaced. If your opener is broken, you're in luck. These repairs don't cost very much and can be replaced easily. You might even be able to do it yourself.

Horsepower You’ll also want to consider the horsepower of your opener. Typically, 1/2 horsepower will work for most doors in newer homes. If you have a heavier solid wood door, though, you may want to opt for 3/4 horsepower so it can lift it with ease. You can also get 1 and 1 1/2 horsepower models, but those are a better fit for commercial or special situations.
Because your garage door can be customized, pricing varies. Our Clopay configurator will help you review pricing as you begin your project. You’ll start with your door size and whether you need a single or double car door. Next, you can choose the collection of door, which gives you options of various materials and styles. Then, you’ll choose your construction, which allows you to decide what you need in terms of energy efficiency, durability and noise control. Lastly, you will be able to visualize the design and see an end price. Other optional add-ons include windows, decorative hardware, smart features and the r-value. However, you do not have to use the configurator. We also install standard garage doors that have not been customized so you know the product price early on in the process.
Tools in Action says the Ryobi Ultra Quiet has plenty of versatility, as you can plug devices into the opener hardware, like a Bluetooth speaker, a fan, or even an 18V Ryobi cordless tool battery. When the opener has power, it will charge the battery. But if your home ever loses power, the 18V battery works as a backup to the garage door opener, allowing it to operate normally.
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).

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.
The electric overhead garage door opener was invented by C.G. Johnson in 1926 in Hartford City, Indiana.[1] Electric Garage Door openers did not become popular until Era Meter Company of Chicago offered one after World War II where the overhead garage door could be opened via a key pad located on a post at the end of the driveway or a switch inside the garage.[2]

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.


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.

The right side of the photo shows the center bearing plate where the stationary cones attach with two bolts. Some doors may have only one spring rather than two equal ones as shown here (indeed, old marks on the shaft show that this door originally had one spring about twice as long on one side). Above the center bearing plate is the bracket and track from the electric opener.


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.

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.

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.

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.
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.

A torsion spring counterbalance system consists of one or two tightly wound up springs on a steel shaft with cable drums at both ends. The entire apparatus mounts on the header wall above the garage door and has three supports: a center bearing plate with a steel or nylon bearing and two end bearing plates at both ends. The springs themselves consist of the steel wire with a stationary cone at one end and a winding cone at the other end. The stationary cone is attached to the center bearing plate. The winding cone consists of holes every 90 degrees for winding the springs and two set screws to secure the springs to the shaft. Steel counterbalance cables run from the roller brackets at the bottom corners of the door to a notch in the cable drums. When the door is raised, the springs unwind and the stored tension lifts the door by turning the shaft, thus turning the cable drums, wrapping the cables around the grooves on the cable drums. When the door is lowered, the cables unwrap from the drums and the springs are rewound to full tension.[7]
