Choosing Between Torsion and Extension Springs for Your Garage Door


Garage doors are an essential part of your home’s security and functionality, and the springs are the unsung heroes that play a critical role in the smooth operation of this massive moving structure. When it comes to selecting the right type of spring for your garage door, homeowners often find themselves dealing with a significant question – torsion or extension springs? This decision isn’t just about personal preference; it can affect your door’s performance, safety, and maintenance in the long run. In this thorough guide from Pro Entry Garage Doors, we’ll walk you through the details of each spring type to help you make a well-informed choice that suits your home best.


Understanding Torsion Springs

Torsion springs are mounted on a metal shaft directly above the door and typically come in sets of two for a double-car garage. They’re considered a more modern and safer option, largely replacing the old-fashioned extension springs in newer garage door installations. Torsion springs store mechanical energy through the act of twisting, which they later release to lift the door. Here’s a closer look at why they might be the right choice for your garage.

How Torsion Springs Work

Torsion springs store energy by wrapping or ‘torquing’ a spring or springs around a steel shaft with cable drums at both ends. When your garage door is closed, the springs are under high tension. Opening the door releases that tension, and the stored energy moves the door upwards, counteracting the force of gravity. This design offers a more controlled and balanced movement that can extend the overall life of your garage door system.

Advantages of Torsion Springs

  • Safety: In general, torsion springs are thought to be safer as they’re installed over the door itself, minimizing the risk of breakage-related injuries.
  • Stability & Balance: Torsion springs provide more lifting power and create a smoother, more balanced operation for your garage door.
  • Longevity: They tend to last longer than extension springs, typically surviving through 20,000 to 40,000 open-and-close cycles.

Installation and Maintenance with Torsion Springs

While the initial installation can be more complex, and usually requires the expertise of a professional, it’s an investment in safety and smooth performance. Periodic inspections and lubrication of the torsion springs are recommended, but the maintenance is often less frequent and less intensive than that required for extension springs.


Delving into Extension Springs

On the other hand, extension springs – also known as stretch springs – are a more traditional choice, often seen in older homes or as part of lower-end garage door systems. They run along the horizontal tracks of the garage door and use tension and resistance to lift the door. While not as advanced as torsion springs, they do offer their own set of benefits.

How Extension Springs Work

Extension springs work by extending and contracting as the door opens and closes. The force stored in extended springs assists the opener in lifting the door, making the door feel lighter and naturally countering the door’s weight.

Advantages of Extension Springs

  • Cost-Effective: Extension springs are generally more affordable than torsion springs, making them an attractive option for homeowners on a budget.
  • Ease of Operation: If correctly adjusted and maintained, extension springs can provide smooth operation of your garage door.
  • Easier Replacement: In the unfortunate event of a spring failure, extension springs are generally simpler for a homeowner to replace.

Installation and Maintenance with Extension Springs

The initial installation is straightforward, and maintenance typically includes checking for rust, making sure the springs are still adjusted correctly, and replacing them if any signs of wear or failure are evident. Regular upkeep is crucial as failure can be sudden and hazardous.


Factors to Consider When Choosing

When deciding between torsion and extension springs, there are several factors to take into account that go beyond how they function. It’s essential to consider your garage door’s size and weight, your budget, safety concerns, and the level of maintenance you’re willing to perform. Here are the key elements to weigh up.

Garage Door Size and Weight

Torsion springs are better suited to handling heavier loads. If you have a double-wide or custom wooden garage door, torsion springs are likely the safer and more efficient choice. If your door is on the smaller or lighter side, extension springs may offer a more cost-effective solution.

Durability and Lifespan

While extension springs are initially less expensive, they have a shorter life expectancy and can require more frequent replacement, incurring additional costs over time. Torsion springs, in contrast, offer a longer functional lifespan and can be seen as a more financially sustainable option in the long term.

Cost Considerations

Your budget is an important factor in the decision-making process. Torsion spring systems are typically more costly upfront, but they offer better value over their extended lifespans. If you’re looking for a low-cost immediate solution, extension springs may be preferable, but it’s crucial to consider the long-term costs associated with repairs and replacements.

Safety Aspects

Torsion springs are generally deemed safer due to their contained mechanism that reduces the risk of injury should the spring break. However, both spring types can pose risks if not properly monitored and maintained. Second to cost, safety should be a significant concern when making your choice.

Frequency of Maintenance

Regular maintenance is a necessity with any garage door spring. Torsion springs, with their sturdier design and more predictable wear patterns, generally require less frequent maintenance. Regular inspection of your garage door by a professional can help catch potential issues early, ensuring the safety and longevity of your garage door system.


In Conclusion

The spring system you choose for your garage door is not a decision to be made lightly. It’s a choice that should be informed by the particularities of your door, your usage requirements, and the safety precautions you’re willing to undertake. While extension springs have their place, the advantages offered by torsion springs in terms of reliability and safety make them the choice for many modern garage door systems.
