What Are Torsion Springs?

Your garage door springs do the heavy lifting every time you open and close your garage. Most homeowners never think about them until one breaks. Knowing which type of spring your garage door uses helps you understand what to expect when it is time for a repair or replacement. In this article, I explain the differences between torsion and extension springs, their pros and cons, and what Houston homeowners should know about each type.

Torsion springs are the most common type of garage door spring found in modern Houston homes. They are mounted horizontally on a metal shaft directly above the garage door opening. When the door closes, the springs wind up and store energy. When the door opens, they unwind and release that stored energy to lift the door.

A typical single-car garage door uses one torsion spring, while a double-car door usually requires two. The springs are held in place by spring anchors and wind on steel drums at each end of the shaft.

Advantages of torsion springs:

• Longer lifespan (15,000 to 20,000 cycles on standard springs, up to 50,000 with high-cycle options)
• Smoother and more controlled door operation
• Better balance, which reduces strain on the garage door opener
• Safer design since the spring stays contained on the shaft if it breaks
• Less wear on other garage door components

Disadvantages of torsion springs:

• Higher upfront cost compared to extension springs
• Requires professional installation (the high tension makes DIY dangerous)
• Slightly more complex repair process

What Are Extension Springs?

Extension springs are mounted on both sides of the garage door, running parallel to the horizontal tracks. Instead of using torque like torsion springs, they stretch and contract to help lift and lower the door. Extension springs are more commonly found in older Houston homes and on lighter garage doors.

Advantages of extension springs:

• Lower initial cost
• Simpler design with fewer components
• Available at most hardware stores

Disadvantages of extension springs:

• Shorter lifespan (around 10,000 cycles)
• Can be dangerous if they snap without safety cables installed
• Cause more vibration and wear on the door and tracks
• Less balanced operation, which can lead to the door opening unevenly

How to Tell Which Type You Have

Identifying your spring type is straightforward. Stand inside your garage with the door closed and look up.

If you see one or two tightly wound springs mounted on a metal rod running horizontally above the door opening, you have torsion springs. The springs will look like thick coils wrapped around the shaft.

If you see springs running along the sides of the door, parallel to the horizontal tracks, you have extension springs. They will look like long, stretched-out coils. You should also see safety cables running through the center of each spring.

Once you know which type you are dealing with, you can measure it. Our free garage door spring size calculator turns the wire size, inside diameter and length into the exact spring rate, and it includes the full torsion spring size chart with DASMA color codes.

Which Spring Type is Better for Houston Homes?

For most Houston homeowners, torsion springs are the better choice. Houston’s hot and humid climate puts extra stress on garage door components. Torsion springs handle this environment better because they operate under less stress per cycle compared to extension springs.

The Houston heat can also cause metal fatigue over time. Since torsion springs have a significantly longer lifespan, they do not need to be replaced as often, which saves money in the long run. If you currently have extension springs and one breaks, it is worth considering an upgrade to torsion springs during the replacement. Ask your technician for a specific quote based on your door size and setup.

Another factor to consider is wind. Houston is prone to severe weather, including strong storms and occasional hurricanes, as documented by the National Weather Service Houston. Torsion springs provide a more balanced force on the door, which helps it stay properly aligned during high winds.

How Long Do Garage Door Springs Last in Houston?

The lifespan of your garage door springs depends on usage and the type of spring installed. Here are some general estimates. Keep in mind that actual lifespan varies depending on usage, maintenance, weather exposure, and the quality of the springs installed:

• Standard torsion springs (10,000 cycles): approximately 7 to 9 years with average use (2 to 4 times per day)
• High-cycle torsion springs (25,000 to 50,000 cycles): approximately 15 to 25+ years
• Extension springs (10,000 cycles): approximately 5 to 7 years with average use

Keep in mind that Houston’s heat can shorten these estimates slightly. Metal expands and contracts with temperature changes, and the extreme summer heat puts additional stress on spring coils. Regular maintenance and lubrication can help extend the life of your springs. Learn more about warning signs that your garage door spring is about to break.

Maintenance Tips to Extend Spring Life

You can take a few simple steps to help your garage door springs last longer:

• Lubricate springs twice a year. Apply a silicone-based or white lithium grease spray to the springs, hinges, and rollers every six months. This reduces friction and prevents rust.
• Test the door balance annually. Disconnect the opener and manually lift the door halfway. If it stays in place, the springs are properly balanced. If it falls or rises, the springs may need adjustment.
• Listen for unusual sounds. Squeaking, grinding, or popping noises can indicate that your springs are wearing out.
• Schedule annual inspections. A professional technician can spot early signs of wear and catch problems before a spring breaks unexpectedly.
