Talking About Springs
Because they work under tremendous tension, understanding how garage door springs work and why they matter is vital for both safety and long-term performance.
Garage door springs are the heart of your garage door system. They may be hidden from view, but these powerful components do the heavy lifting every time you open and close your garage door. Without springs functioning properly, your garage door would be extremely difficult — and unsafe — to operate. Because they work under tremendous tension, understanding how garage door springs work and why they matter is vital for both safety and long-term performance.
Whether you’re hearing strange noises, noticing uneven operation, or want to learn more about spring function and maintenance, this guide covers everything you should know about garage door springs.
What Garage Door Springs Do
A garage door spring is a coiled, high-tension component that counterbalances the weight of your garage door. Most residential garage doors weigh between 130 and 600 pounds. Springs absorb that weight, so your opener doesn’t have to do all the work, and you can lift the door with minimal effort.
When the door closes, springs are wound up and store energy. When the door opens, the springs release that energy to help lift the door upward. Without springs, your opener would strain, wear out faster, or fail well before its expected life.
Because springs store so much energy, they must be installed and maintained correctly. Improper handling can cause serious injury or system damage, so understanding spring types and safe handling practices is essential.
Types of Garage Door Springs
There are two main types of garage door springs used in residential systems: torsion springs and extension springs. Both serve the same purpose — balancing the door — but they work in different ways and are installed in different places.
Torsion Springs
Torsion springs are mounted horizontally above the garage door opening. When the door closes, the springs twist or “torque” as they wind up. They sit on a metal shaft and spin as tension is applied or released.
Torsion springs are considered more durable and stable than extension springs. They tend to last longer and provide smoother, more controlled balance for the door.
Extension Springs
Extension springs are mounted to the sides of the garage door track. When the door closes, these springs stretch outward. When the door opens, they contract and help lift the door.
While extension springs are functional, they place more strain on the door’s hardware and can be more unpredictable under tension. That’s why many modern garage door installations favor torsion springs, especially in higher-use environments.
Why Springs Are Critical for Safety
Garage door springs are under enormous tension — enough energy to seriously injure someone if released improperly. This is why:
• DIY spring adjustments are discouraged for most homeowners
• Broken springs should never be ignored
• Improper handling can cause rapid, uncontrolled movement
When springs are weak, worn, or broken, the door can suddenly slam shut or become extremely difficult to open, creating dangerous situations. That’s why spring health is a core part of garage door safety and should be assessed regularly.
Signs Your Garage Door Springs Need Attention
Not all spring issues are obvious, but certain symptoms signal a need for inspection or replacement:
The Door Is Heavy to Lift
If your garage door feels significantly heavier than usual when opening manually, this often points to reduced spring tension or a failing spring.
The Door Won’t Stay Open
A properly balanced door should stay open halfway on its own. If it falls or rises unpredictably, spring tension may be off, or a spring could be failing.
Loud Noises During Operation
Grinding, popping, or snapping sounds when the door opens or closes can indicate worn or overloaded springs.
Visible Gaps in Spring Coils
If you can see a gap in the coils of a torsion spring, it is a clear sign that the spring has broken and needs immediate replacement.
Door Opens Unevenly
If one side of the door rises faster than the other or appears crooked, it may indicate a spring imbalance, worn cables, or track issues.
How Long Garage Door Springs Last
The lifespan of garage door springs is usually measured in cycles, with one cycle equaling one full open and close. Standard springs are rated for around 10,000 cycles, while higher-quality springs may be rated for 20,000 cycles or more.
In practical terms, a typical homeowner who uses the garage door four to six times per day may need to replace the springs every five to eight years. Heavy-use situations or extreme temperature environments can shorten this lifespan. Regular inspection helps catch wear early, and upgrading to longer-life springs can extend service intervals.
Why Professional Garage Door Spring Replacement Matters
Given the high tension and safety risk, spring replacement should be performed by trained technicians. Professionals have:
• Proper tools for handling high-tension springs
• Experience measuring and matching correct spring sizes
• Knowledge of balance testing and safe installation practices
Attempting spring replacement without expertise can lead to injury and may void warranties or damage system components.
When Springs Break
A broken spring may happen suddenly or be preceded by signs of strain. The most obvious indicator is a loud bang followed by a garage door that won’t open. In this situation:
• Do not attempt to operate the door by force
• Do not try to open or close with the opener
• Contact a professional for immediate replacement
A broken spring cannot balance the door, and using the opener in this condition can damage the motor or other hardware.
Choosing the Right Replacement Springs
When replacing springs, several factors determine the correct choice:
Door Weight
Heavier doors require stronger springs to balance them safely. Technicians use specialized scales or measurements to determine precise spring requirements.
Spring Length and Diameter
Both torsion and extension springs come in different lengths and diameters. Accurate measurements ensure the new springs provide the right amount of tension.
Cycle Rating
Higher cycle-rated springs — such as 20,000, 30,000, or even 50,000 cycles — are built to last longer and endure heavier use.
Material Quality
Springs made from higher-quality alloys resist fatigue and withstand temperature changes better, reducing the likelihood of premature failure.
Spring Maintenance Tips
While spring replacement is a professional job, homeowners can perform safe seasonal maintenance to support spring health:
Test the Door Balance Regularly
Disconnect the opener and lift the door halfway. If it remains in place, the springs are balanced. If it moves on its own, tension adjustment may be needed.
Listen for Noise
Unusual sounds during operation often indicate increased friction or wear.
Keep the Door Clean
Dust, debris, and corrosion can accelerate spring wear. Wipe down exposed parts when performing routine cleaning.
Schedule Professional Inspections
Annual or bi-annual professional maintenance helps detect early signs of spring wear or imbalance before they lead to failure.
Spring Safety Devices and Features
To minimize risk, many modern garage door systems incorporate safety devices that protect against the consequences of spring failure. These include:
Safety Cables
Used with extension springs, safety cables run through the spring to contain it if it breaks, preventing dangerous, flying debris.
Dual Torsion Spring Systems
Two springs share the load on heavier doors. If one spring fails, the other can temporarily support the door, reducing immediate risk and allowing time for service.
Frequently Asked Questions About Garage Door Springs
How do I know if a spring is broken?
A loud snapping or popping sound followed by the garage door refusing to open is a common sign of a broken spring. You may also notice visible gaps in the spring coils, which clearly indicate failure.
Are garage door springs dangerous?
Yes, garage door springs are under extreme tension. Improper handling can cause serious injuries, making them one of the most dangerous components of the garage door system.
Can I replace springs myself?
No, spring replacement should always be handled by a professional. Specialized tools, proper training, and experience are required to safely remove and install garage door springs.
How long do garage door springs last?
Most standard garage door springs are rated for approximately 10,000 cycles, which typically equals several years of normal use. High-cycle springs are available and can extend service life.
Why does my door feel heavy?
A garage door that suddenly feels heavier than normal usually indicates the springs are losing tension or that one spring has begun to fail. This imbalance places extra strain on the opener and should be addressed promptly.
