As we’ve mentioned before, springs are installed within your garage lift mechanism in order to help lift the door. Because doors are so heavy, the lift motor would undergo far more significant wear and tear if it had to lift the full weight of the door every time you opened it. Furthermore, in order to ensure that you can open your door even if you lose power in your home, springs allow you to lift the door by hand when the motor is disengaged.
One can overwind the springs slightly, up to about 8 turns on a standard residential door (that is, 1/2 or 3/4 extra turns), to compensate for undersized or fatigued springs, or increased door weight from painting or humidity, but this results in more stress on the springs and therefore decreased lifetime. If the door is too heavy for that slight tweak, then different springs are needed.
The torsion shaft with lift drums on the ends is above the door. The standard residential door shaft is a 1-inch outside diameter hollow steel tube. The inside diameters of the bearings, drums, and winding cones are sized to loosely fit that 1-inch diameter shaft. At the center is a bearing plate, on either side of which are the torsion springs, or in some cases just one larger spring. The spring pictured on the left in the photo is broken about 1/4 of the way in from its left end. The black shaft with dangling rope and door bracket is the track for the electric opener.
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!
Chris was very professional & thorough. He arrived on time & was able to answer all questions that I had. I was extremely satisfied with the quality of the work he performed. I spoke several times on the phone with Mrs. Carol who keep me informed prior to, during, and after the installation of my garage door. She was very professional, easy to talk with and resolved any misunderstanding that I had.
Now 13 pounds of force must be respected when backed by many hundreds of foot-pounds of stored energy, waiting to be released. Holding this torque is equivalent to stalling a 3 horsepower DC motor. But holding and turning these handles does not require extraordinary human strength. Note that this maximum tangential force depends only on the weight of the door, and the radius of the drums, and is divided by the number of springs (some designs have only one longer spring, as mine did originally, instead of two shorter ones). Higher or lower lift distances imply more or less turns to wind the spring (and thus a different spring geometry), but not more force on each turn.
The best garage door openers have a lifetime warranty on their motor and belt or chain. While it’s common for motors to come with lifetime warranties, belt and chain and parts warranties are often not that generous. However, it’s not uncommon for parts warranties to extend several years. Often the warranties are limited and subject to specific stipulations that vary and are detailed in the user manuals.

For garage doors with windows, try to match the glass style of your house windows to provide a more consistent look. It’s also recommended that you install insulated windows if your garage is heated or air conditioned. If you opt for an uninsulated garage door, make sure it’s made of thick steel – specifically 24-gauge. Thicker steel will help prevent dents.
Speed of a falling door:: Physics tells us that the transit time of a free-falling body is sqrt(2x/g), where x is the length of the fall and g is the acceleration due to gravity (32.2 ft/sec^2). If this typical 150 lb door were to fall an equivalent of 3.75 feet, this falling time would be sqrt(2*3.75/32.2) = 0.48 seconds (480 milliseconds). The terminal velocity is gt, or 0.48 seconds * 32.2 ft/sec^2 = 15.5 ft/sec = 10.6 mph.

Speed of a thrown winding bar:: The springs, being in balance with the door, effectively are able to launch a typical 150 lb door at 10.6 mph speed. An 18-inch long by 1/2-inch diameter steel winding bar happens to weigh about 1 pound. Since momentum is conserved, this 150:1 ratio in weight of the door to the winding bar means the fully-wound springs could potentially throw a winding bar at 10.6 mph * 150 = 1590 mph = 2332 ft/sec, assuming the energy were perfectly coupled and transferred. If the energy transfer were only 1/3 efficient, this would still be the 800 ft/sec speed of a typical pistol bullet. Except it is a foot-and-a-half metal spear, not a bullet.

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.
We lead busy and sometimes hectic lives. It's easy for someone low on sleep and high on stress to accidently bump into their garage door leaving a little damage. If you're lucky it's just an individual garage door panel that's been damaged. This will leave you with the option of garage door panel replacment. There's a chance it might cost you upwards of $150-200 to spot repair damaged garage door panel. If it happens to be an in-production model, they probably will be able to repair or replace the entire panel (if needed) for $250-400. Unfortunately if you've got an older model of garage door the panels may no longer be in production. This might seem like a disadvantage because you'll end up having to just replace the entire door. Many times it's actually easier and more cost effective to just replace the garage door.
Align the upper roller tracks by carefully lifting the door halfway. Lock it in place with two locking pliers, and install the supporting brackets on the back of the rails using 1-1/4 in. perforated angle iron (available at home centers and hardware stores). Install 1-1/2 x 1/4 in. stop bolts, with the threads to the inside of the track, at the end of each upper track.
Garage remotes work by sending a coded signal via radio frequency to the garage door opener. If this code matches that of the opener, then the motor will operate and raise or lower the door. Older devices use a single coded switch, whereas newer systems utilise a rolling code that changes each time the remote is used, increasing the security of the door by offering billions of combinations.
Door styles - in addition to the styles just mentioned, it is important to also consider additional features such as windows across the top of the door to provide light inside of the garage, the use of steel or wood frames to give decorative doors added security and stability, and insulation which can reduce energy costs in the attached garage by an impressive 15 to 20%; and

Here are the new replacement springs I ordered from a distributor, which I found using a Google search for "garage door supply" (search that phrase now). You certainly won't find these at Home Depot or Lowe's (although last I checked Lowe's does carry the less daunting extension spring replacements). I also have a list of some suppliers at the end of this page.

Removing winding cones from an old broken spring for reuse in a new spring: Springs without the winding cones installed are a little cheaper than with the cones. Twisting the old cones into a new spring is easy with a vise and pipe wrench, but it can be tricky removing old cones from a broken spring for reuse. To remove old cones, mount the cone in a vise such that the spring portion is free. Grab the last few turns of the spring in a pipe wrench, engaging the teeth of the wrench into the end of the spring wire. Turn the wrench against the end of the spring wire, releasing the end of the spring from its clamping onto the cone, as you twist the loosened spring off the cone. Another more certain if not brutal method is to use an angle grinder with a thin metal-cutting disk to cut through the loops of spring wire where the loops wrap around the cones, being careful not to nick the cone itself too much. You could also cut into the old spring loops with a just hacksaw and break off the loops with hand tools, but this will require a lot of effort.
The "liability" angle: The flip side of "safety issue" is "liability". This is not used to directly sell you something; it is used to demean the cheaper alternative and prod you into buying a more expensive (and profitable) option. For example, you may be pressured into buying a whole new door, when you just need a new spring, by the salesman telling you he can't just replace the spring due to "liability" issues. Since product liability is a big burden on the garage door industry, and so many old doors (and especially automatic openers) are dangerous, this may be a genuine reason to accept a higher price.

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.
