Replacement spring procedure took me exactly 1 hours including preparation and clean-up for double aluminum garage door. Watch the DIY video on Youtube, save $$, be careful with winding the torsion springs. Rule of thumb: 7' height door garage= 7' x 4 (each 1/4 turn) + 1 = 29 turns (1/4 turn), 8' height door garage = 8' x 4 + 1 = 33 turns (1/4 turn), and so on....
Garage door springs come in two styles: torsion (see above), which mounts on the header above the door, and extension (Photo 1), which floats above the upper roller track. In the past, extension springs were safer to install but didn’t have containment cables running through the center of the spring. Without cable, these springs become dangerous, heavy whips when they break. They also tend to be noisier than torsion springs, and we recommend you use them only if you don’t have the 12 in. of headroom above the door that a torsion spring requires. https://www.youtube.com/watch?feature=youtu.be&v=Z_eZc-kh40c
With garage door installation costs, these numbers also include the actual purchase of the new door and other hardware, including the tracks, adhesives, connectors and fasteners. Keep in mind that if these numbers seem extreme, garage door replacement and upgrades can yield, on average, one of the highest returns on investments for homeowners — with an expected 85 percent.
Delivered on time, with the products described: springs, winding bats, & plastic bushing. Quick install, but apparently I measured wrong, so these total length I bought was larger (which is good as there is less stress on the spring). However this did mean that I needed more than the generic rule of 30 1/4-turns of preload. I wound up with 38 1/4-turns per side for the door to balance when open 3' (per familyhandyman.com recommendations). Would definitely do it again. http://www.youtube.com/watch?v=Z_eZc-kh40c&feature=kp
With Garage Door Doctor, you can rest assured we will replace your springs correctly. We offer 2 types of springs – standard and high cycle. On a 7 foot tall door, our standard torsion springs will last 15,000 cycles and our high cycle torsion springs will last 50,000 cycles. How many years will this last you? That is based off only one thing – usage. For example, with standard torsion spring, if you use your door 4 times a day, you get just over 10 years of life. However, if you use your door 8 times a day, you would get just over 5 years of life. If you use door very little or if you are moving very soon, maybe standard springs would be best for you. If you use your door many times a day or if you don’t plan on moving for a while, high cycle springs would be best for you. Getting high cycle springs will ensure you won’t be stuck with a broken spring for many years to come. Either way, both types of torsion springs we offer work great – its just a matter of when the break again. Call Garage Door Doctor today to have your garage fixed properly!
Most residential garage doors have one of two types of springs: torsion or extension. Torsion springs are heavy-duty springs mounted to a metal rod that runs parallel to the door, directly above the door opening. These springs are loaded, or tensioned, with a twisting action. When the door closes, cables attached to the bottom corners of the door pull on pulleys attached to the ends of the metal rod the springs are mounted on. The pulleys turn the rod, which twists the springs and creates tension. When the door is opened, the springs unwind and help lift the door.
Professionals can replace garage door springs in an hour or two. When you hire a pro, make sure to ask about the quality of the springs they will install. They may well offer several grades of springs to choose from, at a range of costs. Top of the line springs may be guaranteed for life, while economy springs can be expected to last perhaps five years under normal use.
If the door closes but then immediately pops open again, you'll need to check the limit settings, which help the mechanism determine how far to move the door in order to close it properly. If the settings are off, the door will hit the ground before the opener believes it should. It will assume that it has hit an obstacle and will automatically backtrack to avoid damage. Check the owner's manual or the buttons on the motor to adjust the limit settings. It may take some trial and error to get the setting just right.
Just like on a bike sprocket, your cables can sometimes become disengaged. Oftentimes, when a torsion spring breaks, the garage door cable will snap as a result. Sometimes, the cable will cause damage to a vehicle or wall, and if a person happens to be in the way of the cable it can cause serious harm. If you cables have snapped, you should call a professional to help you. See the video above.
Garage door springs support most of the weight of the door when it's opening and closing. A broken spring typically will make the door very hard to lift, rather than causing the door to stick halfway. But some spring problems can contribute to a stuck door. The springs help turn metal wheels, called pulleys, that help lift the door via vertical cables at each side of the door. A pulley can become jammed by an obstruction or possibly a misaligned or hung-up cable. Any problems with springs or pulley should be examined by a garage door professional. Springs (and pulleys) are highly tensioned and can be very dangerous to work with.

It is very important that the replacement springs are calibrated for the weight of your door. Using the wrong size garage door springs will caused the to not function properly and could also cause the opener to break much quicker. Replacing extension springs can be very dangerous and if done wrong can harm someone using the garage door. Make sure you call the Garage Door Doctor to ensure your garage is repaired properly!
These instructions were first posted in 2005, and they were updated in August of 2008. I have been frank about the hazards of garage door repairs and about my own accidents incurred while replacing torsion springs. For what it's worth, you might be surprised to know that I, too, have benefitted from producing these instructions. I have not had any garage door accidents since we first published these on the web in 2005. And, in as much as I have helped keep other DIY-ers out of the emergency room, I consider myself somewhat of a medical practitioner.

Every modern garage door is built with a sensor due to a mandate passed by the government back in the 1990’s that required garage door opener manufacturers to install safety devices. To meet this mandate, most garage doors have a sensor installed on each side of the doorway. They are often referred to as photo eyes since their main function is to maintain visual contact with one another. If that visual contact is broken by an obstruction, then the garage door stops in its tracks. This is meant to prevent the garage door from closing on a vehicle – or even worse, a person.


So if you’re worried that your door may be becoming more energy inefficient or if you’ve noticed a sudden spike in your heating costs, look at the weather stripping on your garage door. While you can replace it yourself, remember that effective weather stripping requires a tight seal, so if you’re unsure, you might save money in the long run by going with a professional garage door service
Keep in mind, the pulley is often cycled through an enclosed casing that is difficult to lubricate directly. By applying enough lubricant to the pulley, you’re ensuring that the whole lifting mechanism is properly lubricated. Furthermore, a jam in this portion of the lifting mechanism is a time-consuming and potentially labor expensive repair that requires a service professional.

Garage Door Installation – This includes the installation of a new garage door. Includes the door itself, the track, cables, springs, hinges, handles, locks and rollers.  It is the complete service and installation of a new door. We inspect all the parts, make adjustments to fit your garage opening, and service all elements during the installation process. Plus, we check to ensure all parts are in proper working order after installed.
If you need to leave the door open until you can make repairs, block the door track on both sides so the door can't move, and unplug the garage door opener (if you have one). If you want to close the door, you can try closing it with the opener, making sure there's nothing in the door's path in case something goes wrong. However, this will put some strain on the opener. Alternatively, you can have a few strong helpers hold the door while you disconnect it from the opener and carefully close the door manually—again, it will be very heavy.
First, make sure your transmitter isn’t stuck under something that could be pressing on the button. For example, your transmitter may have fallen under your car seat and the button is accidentally being pushed by something heavy rolling around on your floor. If that’s not the case, you may also need to check your transmitter’s frequency. It’s possible your neighbors could be running their garage doors on the same frequency as yours, and as they drive by, they’re opening their garage door along with yours.
9.6 Bending the cable will help you avoid problems with the tip at the end of the cable catching on the end bearing plate and causing the cable to come off and the garage door to jam, cock, or fall. Check to make sure the cable is straight in the slot and not sticking out the side. Also the edge of the cable stop should not be pointing to the side as displayed. The cable tip should fit completely inside the drum, with the rounded part facing out so the tip can't scrape the end bearing plate.
