Spring rate, torque, and lift: The spring rate K for these measurements is π*28.5*10^6 * (0.273)^4 / (32 * 140 * 1.72) = 64.5 IPPT. Applying 7.5 turns on this rate will yield a torque of 7.5 * 64.5 = 484 in-lb, which on the 4-inch drums (2-inch radius) yields a lift of (484 in*lbs)/(2 in) = 242 lbs. Again we find good agreement with the approximate door weight of 238 lbs.
Once the shaft, springs, and center bearing plate come down and lay on the floor, the old springs should be easy to get off and new ones slid on and assembled. Two bolts hold the center cones to the center bearing plate. The bearing on the center plate can be oiled while it is exposed from having the springs off. At this point it is a relief to be working with inert parts while standing on the floor rather than energized parts while up on the ladder. You might think it would save a little time to replace the spring with the shaft left up on the wall, but I found it was easier and safer to lower the works down to the garage floor first.
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.
GREAT Company. Called in at 1:30 on a Saturday and my issue was fixed by 3:30 that same day. Our service tech Ken was a great guy who was A++++Can't ask for a better experience than I had with this company. I highly recommend this company and Ken to everyone. And their rates are very fair. GREAT Company to deal with. I wish any other contractor I've dealt with were even half as good as this company. A+++++++ all the way.read more
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. 
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.

The best garage door openers can be controlled from a remote location through your phone. If you’ve ever left home and had a moment of panic, not knowing if you left the garage door open, this feature can give you peace of mind. The door opener’s built-in Wi-Fi connects directly with your home Wi-Fi router, which allows you to close your garage door from wherever you are through a MyQ smartphone app. The Chamberlain Group opener has this feature – it’s a 1-horsepower garage door opener with extra lifting power for unusually heavy doors of over 500 pounds.
Mechanical garage door openers can pull or push a garage door with enough force to injure or kill people and pets if they become trapped. All modern openers are equipped with “force settings” that make the door reverse if it encounters too much resistance while closing or opening. Any garage door opener sold in the United States after 1992 requires safety eyes—sensors that prevent the door from closing if obstructed. Force settings should cause a door to stop or reverse on encountering more than approximately 20 lbs (9.07 kg) of resistance. Safety eyes should be installed a maximum of six inches above the ground. Many garage door injuries, and nearly all garage door related property damage, can be avoided by following these precautions.
Make sure the door is balanced. Close the door and pull the emergency release cord (always close the door first so it can’t come crashing down!). Lift the door about halfway up and let go. The door shouldn’t move. If it slides up or down, the torsion spring needs to be adjusted (or maybe even replaced). Adjusting the torsion spring is dangerous, so don’t attempt it yourself (you could get seriously hurt). Call a pro to adjust it.
Before carrying out any kind of San Antonio garage door repair, we try and understand the problem at the very first place. After being contacted, our professionals will go and visit your garage personally and find out the actual problem. They are the best people to suggest if the problem can be solved with repairs or if the garage door will need a replacement. Usually if the problem is a minor one, it can be tackled with repairs, but in case of grave issues, complete replacement of the doors is recommended.
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.

For Sears Garage Door Installation and Repair Services, making your garage door safe is as important as making it function well. For this reason, all of our repair services and tune-ups feature a 20-point safety check. Our technician will carefully examine your garage door panels, springs, sensors, safety release, hardware, track, and more. This ensures that, not only has our work been done well, but that your garage door poses no danger to your vehicles or family. Due to the intricacy of garage door systems, only garage service professionals should attempt to adjust, repair, or service door equipment.
Annual maintenance. Make an annual check of all nuts and bolts on rails and rollers to make sure they’re firmly tightened. Check the condition of all cables to make sure they’re not worn or frayed. Lubricate rollers and springs with a garage-door lubricant (see How to Fix a Noisy Garage Door for maintenance and problem-solving tips). The door should operate smoothly and be properly balanced. Check the balance by disconnecting the opener and lowering the door halfway- the door should hold its position. If it doesn’t, adjust the spring tension or replace the springs.
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.

Garage door openers are always a nice convenience, but become most appreciated when the weather turns nasty. They are also a near necessity if the task of opening and closing a garage door is too challenging, due to physical limitations. Most are relatively inexpensive and highly reliable, although unless you are very handy, you should probably budget for professional installation.
Give your garage a great look with garage doors from Menards®. Menards® has all the supplies, tools, and accessories you need to install a stylish new garage door. Choose the perfect door from our selection of residential and commercial garage doors as well as roll-up doors for storage sheds. At Menards®, you will find a wide variety of door sizes ranging from 4 feet to 9 feet wide, 10 feet to 16 feet wide, and over 16 feet wide. Because of the layer of insulation, insulated garage doors are generally quieter than noninsulated doors. Insulated doors also offer improved energy efficiency, so you can stay comfortable while working in the garage no matter what the weather's like outside.

When garage door repair isn’t an option — perhaps the current door is beyond fixing or you want to upgrade to a quieter, more energy-efficient model — it’s time to buy a new one. But choosing a garage door is not as simple as it sounds, even when you know the right size for your home. A wide range of materials, styles and finishes are available, and each factor influences the cost. Garage doors are made of aluminum, steel, vinyl, fiberglass, masonite, wood (typically cedar or mahogany), or a composite of several materials. They may be insulated against cold or heat. Traditional and modern styles include raised panel, carriage house or crossbuck. Most styles have window or arch options, and are available in different wood finishes and neutral colors. Because garage doors account for a large part of a home’s exterior, their appearance is usually a homeowner’s top priority. An attractive garage door can increase a home’s curb appeal and resale value.
We’ve been reviewing the best garage door openers for more than half a decade. This year we chose the Chamberlain Premium as our top pick. It’s an efficient, reliable garage door opener, and it comes with a backup battery system that works in a power outage. This model also has a preinstalled timer that closes your garage door automatically so you don't have to worry about whether you left the garage door open.
Here are the winding rods inserted in the winding cone of the unbroken old spring, posed just for a picture. Note that I have carefully placed a sturdy, steady ladder just clear of the swing of the rods, such that when I am standing on the lower rungs to reach the rods, that my head and body are clear of the "kill zone" around the spring and cone. You must have a trustworthy platform to stand on, because a slip or shake of the ladder while you are winding can cause you to lose your socketed attachment to the cone, letting loose the spring. I would not trust an ordinary household step ladder for this purpose.
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.
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.
Every thing the tech demostrated was helpful, he knew how to do his job even if his eyes were shut. Very knowledgeable, took time out to explain every detail about the install process. Very highly satisfied. A d would love to have him for future additional repairs. Would definitely recommend sears and would use you guys again thanks mr.technician for a job well done.

Kevin gave 30 mins advance notice via text before arriving, and he was very friendly and knowledgeable about the Chamberlain garage door opener that we ordered on Amazon. I was pleased with the thorough model description provided, and customer reviews which helped with our decision making, and our package came on the same day that it was ordered! I liked the process of choosing 3 preferred appointment times, and receiving a confirmation email which included Kevin's picture. The install price was very reasonable, and I would gladly use your Home Service again!


Replacing or repairing garage door panels help the garage door operate properly. This means less headaches just trying to get through the day. In addition to ease of getting in and out of your home replacing or reparing garage door panels help preserve the value of the home. Curb appeal matters, especially if the home is going to end up on the market for sale. Any exterior improvement you do to the front of your home pays dividends in your curb appeal. That being said, garage door panel repair is one of the highest dollar fixes you can do for your garage door. The cost to repair the panel is directly associated to the repairman's hourly rate. Installation of new panels start at $240 for a 9' panel and $690 or more for a 16' panel. If you are thinking about replacing your panels, think twice, you might be able to get a brand new garage door for about the same price. Check your options with your professional before replacing your panels.
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.
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.
While there might not be a huge price range when it comes to garage door openers—they are all quite an investment—there a few less expensive options to consider. Here’s a great budget option from Chamberlain. It has a motor that’s equivalent to ½ horsepower and chain drive system that is quick and easy to install. You can also connect it to the MQ technology (gateway sold separately) to use with your smartphone. The product comes with two three-button visor remote controls, a multi-function wall control, as well as a wireless keyless entry system. It comes with a 10-year motor, two-year parts, and one-year accessories warranty.
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.
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.
The lucky-for-you-I-found-another-problem trick: Another trick is to suggest your automatic opener was damaged (or "compromised") by the additional load or shock presented by the failure of the spring(s). The plastic worm gear used in the most common openers (see above) wears normally over the years and tends to leave a lot of debris inside the opener housing. Removing the opener cover reveals a lot of plastic shavings that may be cited as "evidence" you need a new opener, when the gears are actually still serviceable. Nevertheless, you may have indeed worn out the gear if you repeatedly cycled the door with the opener despite having broken springs, which is possible if you have a very lightweight door.

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.
Add the fact that a front-facing garage door can eat up almost 20% of your home’s front facade. With that much curb appeal at stake, a worn-out, beat-up garage door can be a real liability. No wonder that a big majority of homeowners responding to the “Report” gave a garage door replacement project a Joy Score of 9.4 — a rating based on those who said they were happy or satisfied with their remodeling, with 10 being the highest rating and 1 the lowest.
Extension spring systems should always be restrained by a safety cable that runs through the middle of the spring, tying off to a solid point at the rear and front of the horizontal door track. Extension springs represent a hazard to bystanders when a spring, pulley, or cable breaks under tension. Metal parts from extension spring systems can suddenly be launched.

If you’re replacing an existing garage door opener in your home, the simplest method for finding the right horsepower is to check the rating of the unit in your garage and get something with equal or higher power. Most homes have single- and double-car sectional garage doors made of aluminum or steel, which is the most affordable type of garage door. These doors are relatively light, so a motor with rating of 1/2 horsepower is more than sufficient. While 1/3 horsepower motors are available, they can wear out faster than those with 1/2 horsepower in such settings, so it’s a good idea to invest a little extra for a more capable garage door opener.

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.

Ryan Fleming, Technician with Precision Door replaced a broken garage door spring at our home last night and I was so impressed with his knowledge, professionalism and positive attitude that I felt compelled to write this review. We have been customers of Precision Door for over 5 years and have always been pleased with how promptly and cost effectively they perform repair and maintenance work. I highly recommend both Ryan and Precision Door.read more

When you install a new garage door, replace all the hardware as well. If your automatic opener doesn’t have an automatic reversing system that includes photoelectric eyes, replace it. Doors with openers also require two extra pieces of hardware that you’ll see in Photo 4: a support strut (usually included in the door kit) and an opener bracket (not included). For doors with torsion springs located over the door, spend the $50 or so to have a garage door professional release the tension.
I make no recommendations of, and have no connection to, any of the following suppliers. These are just those whom I have learned about from my Web searches, from correspondence with those sending email about their experiences, or directly from the suppliers. I have removed several contacts that were generating complaints to me from dissatisfied customers. I have added this list to this page due to all the email queries I was receiving daily asking where to obtain parts. If you are a supplier and would like to be added to the list, see my email address at the end of this page.
Modern garage door openers include basic to advanced features that improve safety and deter break-ins. Examples include an automatic stop if a descending door encounters a solid object such as the hood of a car and light beam sensors that detect the presence of an object -- or a person or pet -- and stop a garage door's downward movement before accident or injury can occur. Available security options include remote lockouts for when you will be away from home for an extended amount of time, remote codes that change after each use, and lights that turn on automatically when your garage door opens or if movement is detected inside.
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.
Depending on the type and location of the damage you might have an alternative to replacing panels, or entire garage doors. One solution to give new life to your garage door is repair. Small dents, rot, rust or holes can be repair without replacing. Depending on what wrong with the panel, average prices for repair are $130 for steel door repairs, $190 for wood, $170 for aluminum and $150 for fiberglass. Garage door panel repair can save homeowners money, but should be weighed against garage door panel replacment.
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.
After you’ve ordered your new garage door, we’ll perform a site inspection to confirm your door size. We’ll contact you to schedule the installation, and our professional installers will do the rest. They’ll deliver your door, take down the old door, reconnect your opener if there is one, seal your perimeter and provide a final walk-through where they’ll clean up the area and haul away your old door. Additional fees for haul away may apply in some markets. We are happy to provide answers to questions you may have at the time of your garage door and opener installation.
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]
