Torsion Spring vs Extension Spring: Which One is Right for Your Garage Door?

April 27, 2023

Garage doors are a crucial component of every house, as they provide security to our vehicles and other possessions. When it comes to choosing the type of spring for a garage door, you have two options- torsion spring and extension spring. Both are commonly used in garage doors, but which one is suitable for your garage door? In this article, we will discuss the differences between torsion and extension springs to help you make the right choice.

What is a Torsion Spring?

A torsion spring is a coiled steel spring that uses torque to lift the garage door. It is installed on a shaft above the garage door and operates by winding and unwinding when the garage door opens and closes. Torsion springs are known for their durability and longevity. They can last for 15-20 years before needing a replacement.

What is an Extension Spring?

An extension spring is a coiled spring that stretches and contracts to lift and lower the garage door. It is located above the horizontal tracks on either side of the garage door. Extension springs are less expensive than torsion springs but do not last as long. They typically last for 7-10 years before needing a replacement.

Differences between Torsion and Extension Springs

There are several differences between torsion and extension springs that you should consider before making a decision.

Lifespan

As mentioned earlier, torsion springs last longer than extension springs. Torsion springs have a lifespan of 15-20 years, while extension springs need to be replaced every 7-10 years.

Maintenance

Torsion springs require less maintenance than extension springs. This is because they are situated above the garage door and do not require any lubrication. On the other hand, extension springs need regular lubrication to maintain their functionality and extend their lifespan.

Safety

When it comes to safety, torsion springs are considered safer than extension springs. Torsion springs are situated above the garage door, making them less likely to fail and cause injury or property damage. Extension springs, on the other hand, are located at the sides of the garage door, which can pose a safety risk if they break and snap towards someone or something nearby.

Cost

Extension springs are less expensive than torsion springs. This makes them a popular choice for homeowners who want to save money on garage door repairs or replacements. However, it is important to note that while extension springs are initially cheaper, their shorter lifespan means that they will need to be replaced more frequently, which can ultimately end up costing more in the long run.

Which One is Right for Your Garage Door?

The choice between torsion and extension springs ultimately depends on your personal preferences and needs. If you prioritize safety and longevity, then torsion springs are the better choice, despite their higher cost. However, if you are on a tighter budget and do not mind more frequent maintenance and replacement, then extension springs may be a suitable option.

It is important to note that the weight and size of your garage door also play a significant role in determining which spring is right for your garage door. Torsion springs are better suited for heavier garage doors, while extension springs are better suited for lighter garage doors. Consulting with a professional garage door technician is recommended to ensure that you choose the appropriate spring for your garage door.

Conclusion

Choosing between torsion and extension springs can be a difficult decision. Both have their advantages and disadvantages, and the ultimate decision depends on your needs and preferences. When making your decision, consider the lifespan, maintenance, safety, and cost of each type of spring, as well as the weight and size of your garage door. With careful consideration and the help of a professional garage door technician, you can choose the right spring for your garage door needs.
