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.

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.
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?).
We also have a wide range of expertise repairing and installing both residential and commercial doors, meaning we can tackle any problem, large or small. We carry a wide range of doors from one of the industry’s leading manufacturers, Clopay, so you can make the choice that makes the most sense for your home and family while feeling confident that you are getting a door of the highest quality.

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.
I think garage doors always show their age, there's no "timeless" garage door in my opinion. Walk passed a bunch of houses on your block, bet you could guess the time frame each one was installed based on the style of the door. Good thing is that garage door styles will only look dated after 15-20 yrs and even after that, they still look fine as long as they are well kept. I say go with what you love!
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.

The low rating on the CS is due to the fact that inwas out of town and my wife called because the garage door wouldn't open. We had repairs to the only other exit, and the CS said because it could be opened manually, it was no emergency. She was stuck in the house for over Sixteen hours. No emergency crew came out. Steve, a tech who came out the first time, fixed the door. It is not his fault CS took their sweet time to help a 45 year customer. I commend Steve. I do NOT have anything good to say about CS.
When your garage door starts acting up, more often than not it is telling you it's time to do a bit of maintenance. So, before hitting the panic button, try these simple repairs. First, examine the rollers and tracks. If you can't remember the last time you cleaned them (and they look the part!), give them a good brushing and then add some lubricant. Next, perform these simple garage door maintenance tasks.
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.
Smart garage door openers aren't as expensive or hard to find as you might think. In fact, no matter what smart home platform you're using, there is an opener that will work for you. Smart garage door controllers add convenience like remote access, voice control, scheduling and vehicle detection to your garage door. You'll never need to wonder if you left it open ever again. 
Insist on having any old parts returned to you, and have that noted on the written order before work begins. An honest and competent technician will not object to this. The evidence will establish whether you really needed the parts or not, and you can consult another opinion if you have any doubts. This tends to deter the parts-upsell scam, and protects you even if you know nothing about what you're buying while under the pressure of making a costly decision. If the old parts mysteriously "disappear", then you have reason to be suspicious.

We were very pleased with the service we received. The receptionist that took our information over the phone was courteous and efficient. The young man, Nate, who came to the house was on time, respectful of our wants and needs, and very knowledgeable about the job. He was able to fix our door easily. Finally we have a garage door that works with a push of the button! We highly recommend this company for your garage door needs.read more
Spring index lower limit: DASMA standard 102-2004 provides a lower limit of 6 for the spring index, which is symbol C in our formulas above (section 9.3). Other interesting items in this standard include an upper limit for how much the door sags when raised (no more than 1/120 of its width, section 9.2.1), that each of the two bottom brackets should sustain twice the door assembly's weight (section 9.2.2) for a total safety factor of about 4, and that the lift cables should provide a safety factor of 5.
The Lifestyle garage door screen is a fully retractable garage screen door that works with your existing garage door. The Lifestyle features an industry first, fully retractable passage door for ease of entry and exit without having to retract the entire system. The Lifestyle garage screen is fully spring loaded, making opening and closing quick and easy.
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.
The two set-screws in the winding cones have a 3/8-inch square head, which fits a 3/8-inch open-end wrench or 8-point socket, or a 7/16-inch 12-point socket or 12-point closed-end wrench. I carried an extra wrench in my pocket while winding, since I didn't want to be holding a wound spring that I couldn't set because I had dropped the wrench (although one could rest the winding rod against the door in this case while picking up a dropped tool).

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.

Wood garage door: There’s no substitute for the distinctive look of wood. It’s typically made of moisture-resistant cedar, redwood or cypress and offers the most flexibility for custom designs. Depending on climate and exposure, wood doors require more maintenance. The average cost for a 16-by-7 double door made of quality wood: $1,200 to more than $4,000.
The various increments of standard wire sizes differ by only about 0.010 inch, so calipers or a micrometer would be the tool to use to be certain of the stepped size you have, or else a trustworthy ruler marked in tenths of an inch to use the measure-10-turns-and-divide-by-10 trick. The most common wire sizes in the US are 0.207", 0.218", 0.225", 0.234", 0.243", 0.250", and 0.262".
Although you can replace your garage door opener on your own, it’s more difficult than most DIY projects, so following the installation instructions is a must. If you’re not confident you can replace the opener on your own, you should consider hiring a professional, which further increases your costs. You can also expect to pay more if you’re replacing a garage door in addition to the opener.

In the photo, you can see an extra lag screw on the bottom of the plate, reinforcing weak anchoring from the original two screws (hidden behind the springs). This extra screw was applied by a professional garage door technician on a previous repair visit. I have since replaced the backing with a sound plywood panel anchored into the concrete door header. Since these bolts clamp all the opposing torsion to the wall, the attachment must be sturdy.

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 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.

Stress and lifetime: Calculating the maximal stress in the wire is useful for estimating the lifetime. Using the formula above, the bending stress S in the spring wire is 32*238/(π*0.2253^3) = 212 Kpsi. The spring index C is D/d = 2.23 / 0.225 = 9.88. The Wahl correction factor is Kw = (4C-1)/(4C-4) + 0.615/C = 1.15. The Wahl-corrected stress is Kw * S = 1.15 * 212 Kpsi = 244 Kpsi. This predicts about a 10,000-cycle lifetime, which is the standard "cheap spring" configuration originally installed. Note that while this stress is proportional to the torque being applied, it is also in proportion to the inverse third-power of the wire size. Thus slightly heavier wire sizes (and suitably adjusted D and/or L) radically improve the expected cycle lifetime of the spring.

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.
The history of the garage door could date back to 450 BC when chariots were stored in gatehouses, but in the U.S. it arose around the start of the 20th century. As early as 1902, American manufacturers—including Cornell Iron Works—published catalogs featuring a "float over door." Evidence of an upward-lifting garage door can be found in a catalog in 1906.[4]
When ordering springs, be aware that a number of different sizes of springs will make proper replacements, not just the specific size being replaced. The wire size, winding diameter, and length can be traded off to make springs of varied geometry but equivalent torque characteristics. This will also affect the expected lifetime (in cycles) for the spring(s). Since the critical specification for a replacement is the weight it is designed to bear, not the sizes per se, there are likely several stock sizes that replace a given old spring. The spring distributor's inventory may happen to offer only a different size with an equivalent weight-bearing specification. One has to judge whether to trust the advice of the seller in such situations. The seller should have the data to know what substitutions are proper.

Another recent innovation in the garage door opener is a fingerprint-based wireless keypad. This unit attaches to the outside of the garage door on the jamb and allows users to open and close their doors with the press of a finger, rather than creating a personal identification number (PIN). This is especially helpful for families with children who may forget a code and are latchkey kids.


Our value pick is the Chamberlain PD76EV. It costs about $50 less than our top pick, but it has most of the higher-priced model’s advantages. The PD76EV has the same lift capacity, horsepower, lift system and automation compatibility. However, it doesn’t come with advanced features such as a backup power source, close timer and keyless entry pad. If you can live without those, this opener is a great choice.
Single panel doors can also be installed with (one piece track type hardware) that folds the door back with a single horizontal track on each side (which is mounted at the top of the wood frame) and a roller, (mounted to the top of the door on each side. A hinge on each side that attaches to the bottom of each side of garage door. Using track hardware, a car can be parked much closer to the door, as the whole door, when in the open position, rests completely inside of the garage door header. Track type hardware has much less arc when raising and lowering the garage door as opposed jamb type hardware.[citation needed]
