A rolling code is a protocol used by garage door openers to keep your door safe and secure. When the radio signals from your remote control are broadcast to your garage door opener, it uses a specific code to communicate. Older models used the same code every time, making garage door openers vulnerable to burglars using a radio frequency identifier device. 
Had a quick response to my call. thought I might have to wait a couple of days to coordinate their schedule and mine. To my surprise I received service in one and one half hours. Not only that but there was no sales call, technician Mike was fully prepared to give me a quote and complete the work as his vehicle carried everything needed. He very efficiently completed the work and cleaned up after I selected from the options. He replaced the springs all rollers and made needed adjustments expeditiously. I would recommend this firm to anyone needing garage door repairs.read more
Here is what a winding cone looks like without the spring. The threads that grip the inside of the spring coils are ambidextrous, so you can use the same part on either right- or left-hand-wound springs. The cone size is specific for a certain inner diameter of springs, so if you have the wrong size, the cone will slip inside the spring (cone too small), or not fit (cone too big).
The parts, parts, parts trick: You might be told you need new rollers, cables, drums, bearings, etc., when you don't, or at highly inflated prices. Good questions to ask when first calling for service include, "How do I know you will only charge me for the parts I actually need?", and "If you don't have all the parts I need, what will you charge me to come back?"
Today's garage doors come with those door sensors, and if anything is in the path of the door the sensor detects it and raises the door back to the open position. These precautions are important for families with young children or pets. Even if you don't have a mini me or furry friend running around your yard, it's a good idea to have a garage door that is safe for you, your guests and your belongings. 
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.

Next, the torsion shaft is reassembled with the new springs, the drums repositioned loosely on the shaft, this whole assembly slid back into the end bearings, and the drum set-screws tightened down. I tightened the set-screws about 1/2 or 3/4 of a turn after contact with the shaft, which provides a good grip, but does not distort the shaft. The drums can be set on their old positions, if they were correctly installed, which is snug up against the end bearings to remove any longitudinal play in the torsion shaft. Now the lift cable can be reattached to the drums, and a slight temporary torque applied to the shaft to keep the cable taut while the first spring is wound. This temporary torque is conveniently applied with a pair of locking pliers clamped on the shaft, positioned such that they hold the torque by pressing lightly against the wall above the door, before you start the spring winding, The locking pliers stay on the torsion shaft until you have finished the spring winding locked down the spring cone(s) with the setscrew(s), and removed the winding bars. Then you simply remove them with the release on the wrench handle. I feel that any job that doesn't require a trick manipulation with either locking pliers or duct tape (or in the ultimate case, both!) is just too boring. My trusty pliers look a trifle rusty ever since I used them to clamp something on my outdoor TV antenna "temporarily" and left them out in the weather for, oh, several years. The white stuff on the drum is paint overspray from the original painting of the garage interior.
With over 300 independently moving parts, your garage door is a deceptively complex piece of equipment. To help prevent malfunctions and break-downs, it is a good idea to occasionally perform a garage door tune-up to keep all of these parts in good working order. A regular tune-up service by a Sears professional can prevent unexpected door problems and prolong the life of your existing equipment.
The classic telephone bait-and-switch: This time-honored swindle, also called "false advertising", can show up in the garage door business. Here's how this scam works: When you call and say you have a broken spring, and ask for a repair price, you are told over the phone that the price is X dollars, which typically might seem a little better than the competition. When the repairman shows up, after looking at your broken door, he will casually and matter-of-factly tell you it will cost 2X. If they told you over the phone that it would cost X, well, that was only for one spring, and he must (he must, mind you) install not just one, but two. He will act surprised if you object, as if you should have known that from what you were told over the phone. If you expected to really pay just X, it was your fault for misunderstanding because you don't know anything about how garage doors should be repaired. (You will feel intimidated at this, since you honestly don't know anything, else why would you have called a repairman? Intimidation is a powerful tool against customer resistance.) If your door used only one spring to start with, he will insist on converting yours to two, telling you it is safer the next time a spring breaks. If you originally had two springs, he will tell you that he must replace both springs, and you must therefore pay double what was quoted. While it is true that converting or replacing both springs is a good idea, the bait-and-switch pricing is not. The "bait" is the low price quoted to you over the phone, which they never intended to honor, and the "switch" is switching the price to something higher on a pretense. This method of selling is literally criminal (for example, see Florida Statutes 817.44, all states have similar laws), but a service business can usually avoid detection or prosecution because there are no printed advertisements or other tangible evidence, just one-on-one phone calls. If you find yourself in the middle of this trap, then the proper response is to dismiss the repairman without paying a nickel. Don't expect that you will be able to negotiate a fair price with someone who is using criminal business methods. Certainly don't expect that he will accept a lower price because you accuse him of false advertising. If you absolutely cannot wait for another service call, then you'll have to accept the fraud, in which case you should do so quietly. People that use these methods typically have ways to mentally justify their behavior to themselves as a reasonable business practice, and won't react well to your suggesting otherwise, even though they are in fact small-time criminals, not shrewd businessmen.

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.
Measure springs only when relaxed: Measurements must be taken on a relaxed spring because the winding adds significant overall length while reducing the coiled diameter. If you have a paired design, and one is broken and one is intact, then don't try to measure the length of the intact spring with the door down. A wound spring has 7 or 8 turns adding to the overall length, and will therefore be about 2 inches longer than when relaxed. Measure the lengths of the pieces of the broken spring, which will be unwound, and add them together. As a check, one can measure the length of the intact spring after it is unwound in the procedure to follow below. Be sure also to observe whether the springs are originally of equal sizes, because it is quite possible that they are not.
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.

Scott did an amazing job. Your customer service team is excellent. I emailed late on Thanksgiving night my request for service. Your team called my house within 30 minutes and set up an appointment for the following morning. Scott came out and was great. I had purchased the lifetime warranty package with Precision before, and your team delivered. I highly recommend anyone getting a repair to purchase the lifetime warranty package since your team stands behind your product. Rarely do I write reviews - but am happy to share great information on great companies. Thanks for the great service!

Location, climate and building codes are just a few factors to consider when determining which type of garage door is right for your home. Depending on the region you live in, you may need to choose a wind load option for your garage door. Wind loaded garage doors help safeguard your home in high wind prone areas. With garage doors serving as the largest and often times the primary entrance to the home, an insulated garage door may also be right for you.

Door repair business advice (warning to consumers, you are not allowed to know this): Thinner wire is excellent for shortening spring lifetimes, lightening your inventory on a service truck, and getting paid for frequent service calls. This is why your industry chooses to set "standard" springs to have thin wire and despicably short lifetimes. If you want to maximize profits and fleece your customers, install springs that predictably break in about 7 years on a door that should last decades, even though it is just as easy for you to install slightly more expensive springs that should last the life of the door. Remember that the customer wanted the cheapest price, so you need not feel any guilt about this low-balling.

These springs weighed in at just over 9 pounds each, including the winding cones. They are covered with a light film of oil, and at this point the job starts to get messy. The manufacturer has painted them with a "225B24" part number, which no doubt indicates the 0.2253 inch wire size, 24 inches long. Perhaps the "B" indicates the 2-inch inside diameter. Both the left- and right-hand springs have this same number on them.
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.
Correct spring size is determined by factors such as the weight and height of the door. You cannot substitute a different spring and just tighten or loosen the winding to make it balance the load. Why? To maintain cable tension under all operating conditions, the spring must retain about one turn of unspent wind-up at the top-of-travel position, which with the lift drum size and door height predetermines the number of turns of winding at the bottom-of-travel; and furthermore the torsion of the fully-wound spring at the bottom-of-travel must be slightly less than that needed to lift the weight of the door when translated by the lift drums.
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
If return on investment is a priority and you don’t live in the West, your best strategy may be to buy a low- to moderately-priced door that significantly improves the look of your home. Consider adding an automatic garage door opener at the same time. The beauty of a new door and the convenience of an automatic opener are sure to be a winning combination.
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.
Your ad had no cheap coupons or promises.. Just business. Service was more than prompt. No attempt to fix something that was not broke or did not try to sell me anything I did not need. He stated the price at the beginning and stuck to it. (I was so pleased, I did not bother to mention a senior discount.) Very, very pleased that I have found someone I can trust and rely on.
