Understanding Garage Door Springs: When to Replace Them

2023-12-28 5 min read

Garage door springs are among the most critical.and most dangerous.components of your garage door system. They bear the weight of the door and make it possible for you (or your opener) to lift it with minimal effort. Understanding how they work and when they need replacement can help you avoid unexpected failures and potential injuries.

Types of Garage Door Springs

Torsion Springs: Mounted above the door on a metal shaft, torsion springs work by twisting to store energy. When the door is closed, the springs are under maximum tension. When opened, they release that stored energy to help lift the door. Most modern residential garage doors use torsion springs because they're more durable and provide smoother, more controlled operation.

Extension Springs: Located on either side of the door along the horizontal tracks, these springs stretch to store energy. They're more common on older doors and lighter single-car garage doors. Extension springs should always have safety cables running through them to prevent them from becoming dangerous projectiles if they break under tension.

How Long Do Springs Last?

Garage door springs are rated by cycles, with one cycle being one complete open and close operation. Standard springs typically last 10,000-15,000 cycles, which translates to about 7-12 years for the average household that uses their garage door 3-4 times daily.

High-cycle springs are available that last 25,000-50,000 cycles or more. While they cost more upfront, they can be a worthwhile investment for busy households, families with multiple drivers, or anyone who wants to minimize future repair visits and potential inconvenience.

Warning Signs of Failing Springs

Recognizing the signs of spring wear can help you address the issue before a complete failure occurs:

• The door is heavy to lift manually and feels much harder than usual
• The door doesn't stay open when lifted halfway (indicates loss of spring tension)
• Visible gaps in the spring coils where they should be tightly wound
• The door opens a few inches then stops, unable to proceed
• The opener struggles or strains to lift the door, running longer than normal
• Loud bang from the garage (this is often the sound of a spring breaking)

Why Springs Break

Springs fail primarily due to metal fatigue from repeated use. Each cycle stresses the metal, and over time, microscopic cracks develop that eventually cause the spring to snap. Temperature changes can accelerate this process, as metal contracts in cold weather, adding extra stress.

Rust and corrosion also weaken springs over time. Regular lubrication helps protect against rust and keeps the metal supple, potentially extending spring life. However, even well-maintained springs will eventually wear out.it's simply a matter of when, not if.

Why DIY Spring Replacement is Dangerous

We cannot stress this enough: garage door spring replacement should NEVER be attempted as a DIY project. Torsion springs are wound under extreme tension.enough to cause serious injury or even death if they snap or are released improperly.

Professional technicians have specialized tools and training to safely handle spring replacement. They also know how to properly balance the door after installation, ensuring smooth operation and preventing premature wear on other components.

What to Expect During Professional Replacement

When you call Garage Door Petaluma for spring replacement, our technicians will:

• Inspect the entire door system for other issues
• Safely remove the old springs using proper tools and techniques
• Install new, properly sized springs matched to your door's weight
• Balance the door for smooth operation
• Lubricate all moving parts
• Test the door and opener to ensure everything works correctly

Most spring replacements can be completed in about an hour. We recommend replacing both springs at once, even if only one has broken, since the second spring is likely near the end of its lifespan too.

Preventing Premature Spring Failure

While you can't prevent springs from eventually wearing out, you can maximize their lifespan with proper maintenance. Lubricate springs every few months with a silicone-based lubricant, have your door professionally inspected annually, and address balance issues promptly. These simple steps can add years to your springs' life.

If you suspect your springs are wearing out or have already failed, contact Garage Door Petaluma immediately. We offer same-day spring replacement service to get your door working again quickly and safely.
