How to Repair a Garage Door Spring Safely and Effectively
A broken garage door spring can bring your whole day to a halt. It’s one of the most common garage door issues—and also one of the most dangerous to fix if you’re not careful. At Zimmer Gates & Doors, we get calls all the time from Johnstown-area homeowners wondering if they can tackle this repair themselves or if it’s better to bring in a pro.
Here’s what I often tell folks: yes, garage door springs can be repaired, but safety and the right tools are critical. Let’s walk through the basics of spring repair, what to watch out for, and how to know when it’s time to call in a professional.
Why Garage Door Springs Break
Garage door springs—whether torsion springs or extension springs—do a lot of heavy lifting, literally. They balance the weight of the door so it can open and close smoothly.
Springs typically fail due to:
- Wear and tear: Most last 7–10 years or about 10,000 cycles.
- Rust and corrosion: Moisture shortens lifespan.
- Lack of maintenance: Unlubricated springs wear out faster.
- Temperature swings: Extreme cold or heat stresses the metal.
If your door slams shut, feels unusually heavy, or won’t open at all, it’s likely a spring issue.
Types of Garage Door Springs and How They Work
Torsion Springs
Mounted above the garage door, these twist to lift the door and unwind as it lowers. They’re more durable and common in modern systems.
Extension Springs
Located on either side of the door, these stretch to help lift the door and contract when it closes. Often found in older systems, they’re a bit less stable.
Knowing which type you have helps determine how complex the repair may be.
Can You Repair a Garage Door Spring Yourself?
Technically, yes. But proceed with extreme caution. These springs are under serious tension, and if they snap or slip during the repair, they can cause severe injury.
Here’s what I’d suggest if you’re thinking of tackling it:
What You’ll Need:
- Winding bars (not screwdrivers)
- Safety goggles and gloves
- Vise grips
- Socket wrench
- Replacement spring (make sure it matches exactly)
Basic Steps (Torsion Spring Repair):
- Disconnect the opener and lock the door in place with vise grips.
- Unwind the broken spring carefully using winding bars.
- Remove the hardware and slide off the broken spring.
- Install the new spring, ensuring it’s seated properly.
- Wind the spring back up—exact number of turns is critical.
- Lubricate the spring and test the door manually.
If that sounds a bit overwhelming, that’s because it is. The margin for error is small.
Why It’s Often Safer to Call a Pro
Here at Zimmer Gates & Doors, we’ve repaired hundreds of garage door springs for homeowners across Johnstown, Ohio. While DIY repairs might save a little money upfront, they carry serious risks:
- Personal injury: High-tension springs can snap back violently.

- Voided warranties: Some garage door systems require professional service for warranty protection.
Hiring a professional means peace of mind and a longer-lasting repair.

If you notice any of the following, it’s time to take action:
- Loud bang or snap from the garage
