How to Repair a Garage Door Spring


The first step in repairing a garage door spring is determining which type of spring you need to replace. The paint on the end of the spring will help you identify the type of spring you need. Many big box stores and online retailers sell garage door parts. You can also measure the height of your door in inches and divide this measurement by half to get the correct length for the spring.

Types of garage door springs

Garage door springs come in a wide variety of designs. Make sure to correctly measure a damaged spring before attempting to replace it. You may use a measuring tape for this. Measure the distance from the top of the door to the end of the last coil. Then, divide this distance by 20 to determine the diameter of the spring. Most torsion spring coils are close to 5 inches long, so this measurement should be accurate. If the measurement is off even a fraction of an inch, you can end up ordering the wrong spring.

Torsion springs are another type of spring to repair. These springs are designed to withstand considerable force. They are paired with safety cables to prevent the spring from shooting free. This safety mechanism is designed to protect homeowners in an emergency, such as a broken cable. It’s important always to check that the safety cable is in place.

How to measure a garage door spring

Whenever a spring breaks and has to be replaced, the first thing you should do is measure its length. It is usually done by using a tape measure. You can also use the companion spring to determine the length. Once you have the length of the broken spring, you can divide that number by the number of coils to determine the diameter of the wire.

To find the spring size, you need to know its length, wire size, inside diameter, and spring wind. It is essential to know these measurements because they will ensure the longevity of your garage door. The Door & Access Systems Manufacturers Association (DASMA) has established guidelines for correctly measuring garage door springs. It will assist consumers in choosing the proper springs and help retailers organize their products.

When measuring a torsion spring, you should do it when the spring is not in tension. It is because the broken spring will have more tension. Also, it can be dangerous to measure broken torsion springs without proper protection. Always measure the torsion spring separately, not in one piece, to ensure safety.

To measure a torsion spring, you need to know its winding direction. There are two types of springs: right wound and left wound. The directions of the winding cones are different in both cases, so you should make sure you understand the orientation of each spring. Once you have figured out the wind direction, measure the remaining length of the spring, taking note of the size of the broken spring.
