Different Types Of Garage Door Springs Explained

Springs are a crucial component of any garage door. A damaged spring can result in property damage, injury, and in some cases, death. 

There are two common springs used in garage doors: torsion and extension springs.

Here’s a breakdown of each spring, along with how they work, their pros and cons, and pricing differences.

Garage Door Torsion Springs

Torsion springs are commonly used in garage doors and use torque to perform their function. These springs are popular because they’re durable and have longer life spans. 

How does a torsion spring work?

Torsion springs use torque - a twisting or rotating movement. When you open or close a garage door manually or automatically, the coil twists and coils on the shaft.

You can get a variety of different torsion springs, as a result, you’ll need to check the size and opening dimensions of your garage door to choose the perfect one. 

Torsion springs are usually used on sectional garage doors (a hinged panel type door). A single sectional garage door has one spring, while a double door requires two springs.

Why Torsion Springs Are Preferred for Garage Door Opener Systems

In modern garage door systems, torsion springs are often preferred due to their durability, smooth operation, and ability to handle heavier doors.

Durability and Strength: Compared to extension springs, torsion springs are stronger and last longer. While torsion springs are mounted above the door and twist to provide lifting force, extension springs stretch and are more prone to wear over time. A standard torsion spring can last up to 20,000 cycles, making it ideal for residential and commercial use.

Better Balance: A torsion spring system provides better balance and smoother operation. This is especially important for garage door opener systems, as it reduces stress on the motor, ensuring the system lasts longer.

Fewer Exposed Parts: Torsion springs have fewer exposed parts, which means they require less maintenance. They are typically installed at the top of the door, making them safer for homeowners who may not want to deal with frequent maintenance.

Choosing the right spring system for your garage door can greatly improve both functionality and safety, making torsion springs the go-to option for most homeowners.

Garage Door Extension Springs

Extension springs use extension to perform their function and are usually found in the horizontal tracks on both sides of a garage door. 

Extension springs are also a great alternative to torsion springs since they can be easily placed even when there is low headroom for torsion springs. 

How do extension springs work?

The extension springs extend when a garage door is being opened. The more the door is open, the more force is placed on the springs.

Since the springs experience a large amount of force, there must be safety precautions in place during installation. You’ll notice that extension springs are often paired with safety cables. These safety cables need to remain in place at all times since any movement can result in the spring shooting loose.

Safety cables prevent the extension spring from breaking free and injuring you and your family members. 

Extension springs aren’t commonly used anymore since they can be complex to assemble and require regular maintenance. 

How to Measure Garage Door Springs Accurately

When selecting the correct type of spring for your garage door, accurate measurement is essential to ensure the system functions safely and smoothly. Garage doors rely on precise spring systems, and measuring them properly is crucial.

Torsion Spring System Measurement: For standard torsion springs, begin by measuring the length of the spring when it is not under tension. You should also measure the inner diameter of the coil and the wire diameter, which determines the strength and torque. The exact size of these measurements will vary based on the weight of the garage door.

Extension Springs Measurement: For garage door extension springs, you'll need to measure the springs when the door is closed. The length should be taken while the springs are fully contracted. It’s also important to ensure you have one spring on each side of the door, as extension springs work in pairs.

Correct measurements are essential to ensure that the springs can handle the weight of the door, preventing damage to your garage door system. If you’re uncertain, a garage door professional can assist in measuring and choosing the right spring.

Extension Vs. Torsion – Is One Type of Garage Door Spring Better Than The Other?

Both extension and torsion springs experience tremendous force when they’re functioning, as a result, you need to ensure that they are well-maintained. Springs are crucial garage doors components that require inspections every now or then. 

Broken garage doors springs can be expensive to fix and can cause damage to your property and injure your family members.

How do you know which spring is right for your garage door?

It all depends on your budget and needs.

Extension springs are usually more affordable, consequently, they're often used in new residential homes. The drawback here is that extension springs have a much shorter lifespan. 

On the other hand, torsion springs are on the higher end of the price scale, but since they have fewer exposed parts, they are also more durable and last much longer than extension springs.

Common Signs Your Garage Door Springs Need Replacement

Over time, garage door springs wear out due to repeated use. Recognizing when your springs need replacing can prevent damage to the garage door system and ensure safety.

Here are common signs of a broken spring or one that’s nearing the end of its life:

1. Uneven Door Opening: If your garage door opens unevenly or fails to open smoothly, it may indicate that one of the springs has failed or is worn out.
2. Loud Noises: A garage door opening with a loud bang or squeal often points to a broken spring.
3. Door Fails to Stay Open: If your door closes unexpectedly after being raised, or it doesn’t stay fully open, it could be a sign that the torsion spring system or extension springs are no longer functioning properly.
4. Visible Damage to Springs: If you can see rust, corrosion, or gaps in the torsion springs, they are likely on the verge of breaking.

Always consult a garage door service technician to replace any broken springs, as attempting to fix them on your own can be dangerous.

The Importance of Garage Door Spring Maintenance for Safety

Maintaining your garage door spring system is crucial for ensuring the safety of your home. Both extension springs and torsion springs are under constant pressure, and without regular maintenance, they can fail suddenly, causing significant damage or injury.

Lubrication and Inspection: To keep your garage door system operating smoothly, regularly inspect the springs on each side of the door for signs of wear, such as rust or stretched coils. Lubricating your springs with a silicone-based spray helps reduce friction and prolongs their lifespan.

Safety Cables for Extension Springs: If your garage uses extension springs, ensure that safety cables are installed. These cables help secure the springs in case they snap, preventing them from flying off and causing injury. Extension springs store energy differently than torsion springs, making them more prone to sudden breaks if not maintained properly.

Annual inspections by garage door professionals can help you spot any issues early, ensuring your springs are safe and functional.
