This page is a description of how I replaced torsion springs on a garage door. You may find that my experience either frightens you from trying such a stunt yourself, or encourages you to give it a try. You may curse me for revealing the techniques supposedly known only to the trade, or perhaps thank me for explaining how it's done. All the secrets are revealed below. Even if you hire this work out, just knowing how it is done will help you shop for the best deal and avoid falling prey to overcharging tricks.
We looked for wireless garage door openers that have the power to lift the heaviest doors and found that 1/2-horsepower motors are best suited for standard aluminum sectional doors used on most homes built from 1990 to today. The 3/4-horsepower garage door opener motors can lift wooden doors up to 550 pounds. Each model we looked at can open a standard 7-foot door, and extension kits are available if your door is taller.

Measurements: With the door in the down position, I measure a wire size of 0.273 inches, outside diameter of 2.0 inches, and overall length of 41.5 inches. Relaxing the spring shortens the length by about 7.5 coils of wire, so to estimate the relaxed length, we deduct the wire diamter of 0.273 inches times 7.5 from the 41.5 inch wound length, yielding an estimated relaxed length of 39.5 inches. The mean coil diameter is 2.0 - 0.273, or 1.73 inches. Perhaps this was actually a 40-inch-long spring with a 1.5 ID, 1.75 mean diameter, and 2.0 OD, but let's continue on calculating with the actually observed sizes. The number of coils in the relaxed spring is the relaxed length of 39.5 inches divided by the wire size of 0.273 inches, or about 145 coils. Deducting about 5 dead coils at the ends yields 140 active coils.

Security Lights: Most newer garage door openers have at least two bright light bulbs, as well as lights activated by motion. On the other hand, some older or cheaper openers are limited to a single light bulb. This doesn't help much with a garage darkened by shadows, leaving you unsure if the rustling in the corner is your cat … or a skunk that snuck into the garage.

Permits must be applied for when you are building a new home or structure. This permit will cover the building of the structure and cover the inspection for your garage door. The inspection process for a new door is pretty simple. The county will want to make sure that you have a garage door installed that meets local wind rating standards. In Mecklenburg County, that standard is 90 mph. That means that your door must be rigid enough to withstand 3 second gust by winds of up to 90 miles per hour.

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.
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.
Beware of improprer prior installations: Sometimes the existing door installation is not correct, and the old springs should not be used as a specification for replacements. For example, the old springs might have been replaced with incorrect sizes because the last repairman didn't have the right one on his truck. If your door has never worked quite right, something like this might be the cause. To correct this, you must use the weight of the door to specify the spring, either from a spring rate manual giving spring torque constants, or from the formulas below.
The not-so-competitive advertising trick: How about this racket: We have all heard how you should get at least three bids for any home improvement jobs, right? In some areas the largest ads in the yellow pages are from a single business using various names and phone numbers, masquerading as independent competitors. When you call asking for prices, "they" all quote you very high numbers. You are tricked into thinking you have shopped around for the prevailing price. (The more modern version of this is multiple Web sites that all direct you to call the same person.) If you've ever had to call a plumber you may have unknowingly been a victim of a similar trick.

Horsepower: The horsepower measurement, often shortened to HP, describes the power the garage door opener motor has. A motor with a greater horsepower measurement will open and close the door more quickly, while also being able to handle larger and heavier doors. Motors between 1/2 HP and 1 HP are the most common for residential garages, FeldCo says.
The Decko 24300’s 3/4-HP motor provides the power you need if you've got a big or heavy door and, while it may not have all the bells and whistles of some “deluxe” models, the Decko does everything you need it to do. We appreciate the fact that this model comes with two remotes, an internal panel for controlling the lighting and opening/closing the door, a wireless external keypad with a security code, and a rolling code access system that keeps intruders out of your garage. The Decko will save you a few dollars over some of the more premium garage door openers, but it will still give you an excellent performance.

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.
Resetting the drums, if needed: If the drums were incorrectly set in their old positions, one must reset both drums in new positions on the shaft. This is complicated by the presence of old dimples in the torsion shaft from previous setting(s), which must be avoided lest they improperly influence the new setting of the drums. To begin this process of resetting the drums, the door must first be lowered and resting level on the floor, the spring(s) must be in the unwound condition with their set-screws loosened, and the lift cables wrapped around the drums. If for some reason the door does not rest level on the floor, such as the floor being uneven, then insert temporary shims between the door bottom and the floor to bring the door up to level. Loosen the set-screws on the drums, and turn the torsion shaft to avoid the old dimples from the set-screws in the old drum position. Tighten the set-screw on the left drum (that is, on your left as you face the door from in the garage), creating a new dimple, and apply tension to its cable with the locking-pliers technique, enough tension to keep the cable taut but not enough to start to move the door up. Attach and wind the cable on the opposite (right) drum by hand until the cable is similarly taut, and set the screw, remembering that tightening the screw will tend to add a bit of extra tension to the cable. Both drums should now be fixed on the torsion shaft, with the cables about equally taut (listen to the sound when you pluck them like a guitar string) and the door still level on the ground. Setting the left drum first, and the right drum second, will allow you to take up any slack in the cable introduced by the left drum rotating slightly with respect to the torsion shaft as you tighten the set screws. This alignment and balance of the cables, drums, and door is critical to smooth operation and proper closing. If you have a single-spring assembly, the distance along the torsion tube from the spring cone to one drum is longer than to the other drum, which allows a bit more twist to one side than the other, and you may have to compensate with the setting of the drums.

Most wood doors are sectional roll-up doors, though a swing-up wood door that’s meant to be painted can be affordably built in the driveway from a wood framework and plywood. Custom wood doors are typically made of durable softwoods such as Douglas fir, cedar, redwood or cypress, or from hardwoods such as oak or mahogany. Appearance-grade hardwoods are relatively expensive.

Most doors come with electric door openers. After a while these openers malfunction and need to be replaced. If your opener is broken, you're in luck. These repairs don't cost very much and can be replaced easily. You might even be able to do it yourself.

An enantiomorphic (mirrored) pair of springs, such as my standard door uses, will consist of one left-hand and one right-hand spring. Note that this "right" and "left" has nothing necessarily to do with whether the spring is mounted on the left or right of the center bearing plate. Indeed, with my standard door, if you stand inside the garage, facing out, then the spring to the left is a right-hand-wound spring, and the spring to the right is a left-hand-wound spring. The photos above and below of the broken spring show that it is a right-hand-wound spring.

If your door has two springs, most professionals and research online says that replacing both springs is the best option. Most torsion springs are rated for 10,000 close/open cycles. If only one of your springs is broken, both springs are still recommended to be replaced. Considering that your second spring will break soon anyways, this added on fix is only going to cost you about $50 extra to assure that you don't have to pay another service fee for a second visit.


In Maryland, wildfires are not common. However, thunderstorms are, and they often take out the power. Do not get stuck when power outages occur again. Consider a battery backup. If you are interested in finding out more about it, simply give us a call. Want to know which openers have them? Please take a look at these Precision-preferred garage door openers.
Using your drill, add tension to the torsion spring. This system uses a single spring for a double door, but many manufacturers use two springs for a double door. The painted line on the spring acts as a gauge for the number of turns you put on the spring. To keep the bar from turning while you’re adding tension, attach a locking pliers to the bar on both ends of the spring. Apply lubricant for garage doors to the spring.
