6.1 It is time now to unwind the old spring that is not broken. A few warnings are in order. NEVER, NEVER, NEVER touch a set screw without first inserting a properly fitting bar into the winding cone! Also, do not use box or socket wrenches for the set screws. If the cone slips, the wrench could break your hand in 10 spots before unwinding completely. It's my guess that this is the number one cause of trips to the emergency room for inexperienced homeowners fixing or replacing their springs.

After working on the car, you find a big oil stain on the driveway. Pulverize a scrap piece of drywall with a hammer (any new home construction site will have dumpsters full of waste pieces of drywall). Crumble the pulverized drywall with your hands and sprinkle on the stain. Leave it overnight, and rinse off in the morning. Reapply and brush in with a bristle broom in cases of stubborn stains.


A garage door spring replacement should cost between $175 and $225 for a single tension spring and between $250 and $300 for two tension springs. Most garage door companies carry a wide enough variety of spring sizes to cover most residential doors. As long as the proper amount of turns are put on the spring, there are more than one correct springs to use for any one door.

The average lifespan of torsion springs is determined by its cycle count. Garage Door Medics provides springs with an average of 25,000 cycles and we can provide custom size springs for any door. The industry standard is 10,000 cycles. When a garage door is used more frequently, the springs may not last as long. If you begin to see signs of wear, it’s time to give Garage Door Medics a call!
The electronics should also be inspected before or after investing in the cost of replacing the garage door panel to make sure your door will operate properly. The sensors prevent the door from closing on someone's foot or a pet. If they don't work, someone could be injured. Also check to make sure the door opener works, since you could otherwise be locked out of your garage.

The average cost is $190 for 2 springs in the Detroit area. This is for steel doors weighing under 140 lbs or known as a standard spring which fits 90% of all doors. The remaining 10% are wood doors or large heavy insulated doors. Expect to pay an additional $60 - $100 for a set of these. Garage Door Companies rarely carry these springs on their vehicles or stock them. Therefore, they either buy them locally at a premium or special order them. Regardless, its an additional trip that gets figured into the cost.
9.13 If you have a spring anchor bracket with a fixed steel bearing, check for wear at the point where the shaft and bearing race meet. The shaft needs to be free to slide sideways inside the bearing. File the shaft if needed. Lube the bearing. Notice that only one bearing is needed for two torsion springs. This bearing keeps the shaft from rubbing against the inside of the stationary cones and on the center bracket. Your garage door may not have a center bearing. If so grease the shaft where it will be rubbing the bracket and the insides of the cones.
9.4 Slide the end of the shaft into the end bearing plate. Tighten the set screws an additional 1/4 to 1/2 turns beyond the point you finger-tightened them. Add an additional 1/4 turn if you could not find the original set screw indentations in the previous step. Heavier wooden garage doors may require an additional 1/4 turn. Caution: Under-tightening the drums could cause the drum to slip and the door to cock or fall. Over-tightening the set screws could damage the shaft or drum, resulting in the same problems. This is a critical step. http://youtube.com/watch?feature=youtube_gdata&v=Z_eZc-kh40c
A garage door is a large door on a garage that opens either manually or by an electric motor (a garage door opener). Garage doors are frequently large enough to accommodate automobiles and other vehicles. Small garage doors may be made in a single panel that tilts up and back across the garage ceiling. Larger doors are usually made in several jointed panels that roll up on tracks across the garage ceiling, or into a roll above the doorway. The operating mechanism is spring-loaded or counterbalanced to offset the weight of the door and reduce human or motor effort required to operate the door. Less commonly, some garage doors slide or swing horizontally. Doors are made of wood, metal, or fiberglass, and may be insulated to prevent heat loss. Warehouses, bus garages and locomotive sheds have larger versions.
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.

The winding and unwinding is done at a metal fitting, called a winding cone, attached to the outside end of the spring. You stick a winding bar into one of the four holes in the cone and use the bar as a lever to turn the cone. Once you've completed a quarter turn, insert the other bar into a different hole in the cone and let the bar lever against the closed garage door to hold the spring tension. This allows you to move the original bar to repeat the process, alternating the bars with each quarter-turn. It takes about 30 quarter-turns to fully tension a standard torsion spring.
Doors with extension springs have two sets of pulleys (which are sometimes called sheaves): one at the end of each spring and one at the top of the vertical door track. They also have two cables on each side. One cable attaches to the bottom of the door, runs up and over the pulley above the door and around the spring pulley and then attaches to the door track bracket. The other cables are safety cables that run through the middle of the springs and are fixed to a track bracket at both ends. These cables restrain the springs if they break under tension. All extension springs must have safety cables.

There are two types of garage door springs: torsion and extension. Torsion springs are horizontal and located near the top of the garage door. Check for a gap between these springs indicating a break. Springs on the sides of the garage door are extension springs. Inspect them to see if one or both of them have broken. If you have a broken spring, call a garage door technician to fix it for you as soon as possible. Never operate a garage door with a broken spring; it could severely damage the door and the operating system. Never attempt to replace a broken spring on your own, either. Replacing broken garage door springs is very dangerous for anyone other than a certified, professional repair technician.

Gather the supplies and tools needed for changing the springs safely. In addition to the torsion springs you'll need a minimum of one or two 10" vise grips, an adjustable wrench, and two 1/2" X 18" winding bars. Most hardware stores sell 1/2" X 36" steel rods that can be cut in half. You'll also need a firm ladder and a rag for cleaning your hands. A ruler and a file may also be necessary; a socket wrench and sockets would shorten the time required. Finally, make sure your garage is lighted well.
6.4 Test the fit of the bar in the cone before loosening a set screw. Insert one end of your winding bar into one of the holes of the winding cone. Pull down on the bar slightly to make sure the set screws are tight. Position your ruler between the bar and the garage door. Move the bottom of the bar from side to side and measure the play. It should be less than an inch and a half. If it is over 2" either get someone else to change your springs or have someone make some bars that will properly fit the cones.

Would have appreciated the technician to have explained in better detail about the quality of the first doors we received in our home. The garage doors that were installed recently were an upgrade. I would have selected the better quality of doors with the first installation if it had been explained in better detail and time of decision with the first doors. But, I really love the doors that were recently installed! Explained much better with the new doors. Time was well spent on my decision making and the technician this time was very helpful and knowledgeable. Thank You! Cathy Walsh
Even though most of us are likely used to seeing this small spring in place on our garage door, we don’t often think too much about it, and we simply count on it working when we need it to. Unfortunately, it doesn’t last forever and will eventually need to be replaced. It’s best to be proactive and notice when it begins to look worn down before it actually breaks. Otherwise, you may find yourself trying to open the garage door to drive to work one morning, only to find that the door won’t open because the spring is broken.
•	Extension springs: Garage door extension springs stretch to provide lifting power for the door. These springs are typically made of steel and mounted above the horizontal track of the garage door. A safety cable should run through your extension springs to prevent possible injuries or property damage. Extension springs are the most common type of garage door spring for residential use and can break after excessive usage. 

If you pull the red emergency release rope on your automatic opener and you still can’t lift the garage door, you probably have a broken spring. The counterbalance spring is what lifts the garage door, not the garage door opener. If the spring is broken, the door is dead weight. A garage door can be lifted, but it is going to require some muscle to get it up. It is also important to lift the door evenly so it does not jam in the tracks.
If your garage door is equipped with extension springs (usually seen on single car garages), the cable and pulley might be hanging down when the spring break's. Extension springs use a two pulley system on each side of the door to lift the garage door up and down. When the spring break's everything goes haywire, causing the cables to become twisted or even frayed when they catch on the metal edge of the track. There is a lot of force being released when a garage door spring breaks.
Another scenario is the garage door goes up very slowly when using the automatic opener. Some garage door openers have DC motors that start off slow when opening and then kick into a higher speed. If you have a broken spring, the opener might stay in the slower speed due to the heavy weight of the garage door. If this happens to you, close the garage door and pull the emergency release rope. Next, try to lift the door. If it is really heavy, then you most likely have a broken garage door spring.

If the garage door is broken or damaged, it can affect the feeling of the entire house. It’s not only an inconvenience, but it can also make your entire house feel less sophisticated and less functional. If you happen to be trying to sell your house, this can seem like a major detraction. Even if you’re only having guests over, you may feel as though you’re doing less than putting your best foot forward by having a broken garage door.

While it would be wonderful if door springs lasted forever, the reality is that the simple act of opening and shutting the door multiple times every day isn’t easy. It’s hard on the springs, even though they’re built to do it. Most springs will last for a while, but they won’t last forever. The regular wear and tear of endlessly opening and shutting the door breaks them down and eventually, they’ll need to be replaced. https://m.youtube.com/embed/Z_eZc-kh40c
