Why DIY Spring Replacement Is So Risky
Garage door springs are tightly wound and under extreme tension. They’re designed to lift doors weighing hundreds of pounds, and when that force is released the wrong way, it can cause serious harm.
Most homeowners don’t have the right tools or experience to safely remove or install springs, especially torsion springs. Even if the job seems straightforward, one wrong move can cause lasting damage to the system or result in injury.
Being informed is the first step. Here’s what to avoid:
5 Garage Door Spring Replacement Mistakes
Even small oversights can result in major problems. These are the top spring replacement mistakes we see in Maine homes, and what you should do instead to keep your garage door operating safely and reliably. Whether you’re attempting a DIY fix or hiring someone inexperienced, these errors can compromise your entire system and lead to costly repairs down the line.
1. Using the Wrong Type of Spring
Not all garage doors use the same kind of spring. Using the wrong type, or installing the wrong size, can throw off the balance of the door, make it harder to open, or damage the opener over time. Torsion springs and extension springs function differently, and your door is likely engineered to use one specific kind.
- What it means: You might install an extension spring when the system is designed for torsion, or choose the wrong length or strength rating.
- Why it matters: An unbalanced door won’t open or close smoothly and can stress your entire system, including the opener, tracks, and rollers. Over time, this can shorten the lifespan of other garage door components and lead to uneven wear.
2. Installing Springs With the Wrong Tension
Springs need to be calibrated with the correct number of turns or stretches based on the weight of your garage door. Too much or too little tension affects how the door opens and can be dangerous, not just to the door, but to the person handling it.
- What it means: Over-tightened springs may cause the door to fly open too quickly; under-tightened springs won’t lift the door properly or may leave it stuck halfway.
- Why it matters: Misadjusted tension can lead to jerky movement, excessive noise, or sudden door slams. It also increases the chance of spring failure or causes the opener to work harder than necessary.
3. Forgetting to Replace Both Springs
Many garage doors use two springs for balance. When one fails, the other is often close behind due to equal wear. Replacing only one spring may save money upfront but often leads to poor performance and early failure of the second spring.
- What it means: The new spring works harder than the old one, which may break soon after. The system becomes unbalanced, placing strain on tracks and hinges.
- Why it matters: Uneven spring tension can damage tracks, hinges, and openers over time. It can also create unpredictable movement, increasing safety risks for anyone near the door.
4. Replacing Springs Without Safety Cables
Extension spring systems require safety cables to prevent springs from whipping across the garage if they snap. Skipping this critical step puts people and property at risk, even if the springs are brand new.
- What it means: You’ve installed a new spring but left out the cable that catches it in case of failure. Without it, a snapped spring can turn into a projectile.
- Why it matters: A snapped spring without a safety cable can break windows, dent cars, or cause serious injury. These cables are inexpensive, easy to install, and essential for safe operation.
5. Attempting Repairs Without Proper Tools
Garage door spring replacement requires specialty tools like winding bars, vice grips, and torque wrenches. Using makeshift tools, like screwdrivers, socket extensions, or pliers, is not only ineffective but extremely dangerous.
- What it means: You’re improvising with tools not meant to handle spring tension, and that puts you at immediate risk of injury.
- Why it matters: Improper tools can slip or break under tension, leading to accidents or failed installations. Without the right equipment, it’s nearly impossible to set the correct spring tension or safely complete the job.
Why Professional Spring Replacement Is the Safer Option
While some homeowners have the skills for basic garage door maintenance, spring replacement is a different story. Even confident DIYers often underestimate the danger.
A professional technician will:
- Use the correct spring type and size based on your door’s weight and dimensions
- Adjust the tension precisely for smooth, balanced operation
- Inspect and replace safety cables if needed
- Test the entire system after installation
- Offer warranty coverage on parts and labor
