When your garage door refuses to open or closes unevenly, the problem often comes down to the springs. These hardworking components lift hundreds of pounds every time you use your door. When they fail, they fail suddenly. If you’re dealing with a broken garage door spring, you’re not alone. In fact, it’s one of the most common issues property owners face with their commercial overhead doors. While garage door spring repair might seem straightforward, it’s actually dangerous work. This work requires specialized tools, training, and safety equipment. That’s why understanding what’s happening with your springs matters. Plus, knowing when to call a professional can save you time, money, and potentially serious injury.
Why Garage Door Springs Break
Garage door springs don’t last forever. Most torsion springs are rated for about 10,000 cycles—that’s one complete opening and closing. For a busy commercial facility, that might only be 3-5 years of service. However, several factors speed up spring failure.
Cold weather makes metal more brittle. That’s why so many springs break during winter months. Rust and corrosion weaken the metal over time, especially in humid climates. Facilities near saltwater face even more risk. Additionally, lack of maintenance means springs operate under more stress than necessary.
Another major factor is improper spring sizing. If your door had springs installed that weren’t properly rated for the door’s weight, they’ll wear out much faster. This is particularly common after a quick replacement job by an inexperienced technician. The springs work harder than they should, cycle after cycle. Eventually, they simply can’t handle the load anymore.
Warning Signs You Need Garage Door Spring Repair
Commercial door springs typically give you warning signs before they fail completely. Recognizing these symptoms early means you can schedule a repair before you’re locked in or out of your facility at the worst possible time.
The Door Won’t Open or Barely Lifts
When you press your opener button and the door only rises a few inches before stopping, that’s a classic sign of spring failure. The opener motor alone can’t lift a commercial door. It needs the springs to counterbalance the weight. Without that assistance, the safety sensors kick in and stop the motor to avoid damage.

One Side Moves Faster Than the Other
If your door opens unevenly or one side appears higher than the other, you might have a broken spring on one side. Commercial doors often use multiple springs. When one fails, the door becomes unbalanced. This creates dangerous stress on the remaining hardware. It can cause additional damage if not addressed quickly.
Loud Bang or Snap
Many property owners report hearing a loud bang or popping sound when a torsion spring breaks. That sound comes from the sudden release of tightly wound tension. If you heard this noise coming from your overhead door area, there’s a good chance you’re dealing with a broken spring.
Visible Gap in the Spring Coil
Take a look at the springs above your door. If you see a gap of an inch or two in the tightly wound coil, that spring has broken. Sometimes the gap is obvious, especially on torsion springs mounted on the shaft above the door. That visible break means the spring can no longer provide the lifting force your door needs. The International Door Association also recommends monthly visual inspection of garage door springs, cables, rollers, pulleys, and mounting hardware for signs of wear or damage.
What Professional Garage Door Spring Repair Involves
Because of the extreme tension involved, professional technicians follow specific safety protocols during spring replacement. Here’s what happens when you call for professional overhead door repair services:
Step 1: Safety Assessment and Preparation
A certified technician will first assess the entire door system to identify all issues. Since springs work together with cables, drums, and other components, your Facility Door Solutions professional checks everything for wear or damage. The door is secured in the closed position using locking pliers or another safety device. This prevents unexpected movement during the repair.
Step 2: Release Remaining Tension
Even a broken spring may have residual tension stored in it. Your certified technician uses specialized winding bars—never screwdrivers or pry bars—to safely release this tension. This step requires precise technique and professional expertise. The torque involved can cause serious injury if handled improperly.
Step 3: Remove Damaged Springs
Once the tension is released, your technician removes the broken springs from the torsion shaft. This also involves inspecting the shaft itself for wear. They also check the condition of the bearings, drums, and cables. If the springs caused secondary damage when they broke, your Facility Door Solutions professional identifies those issues before proceeding.
Step 4: Install Properly Rated Replacement Springs
Here’s where professional service makes all the difference. Your certified technician calculates the exact spring size needed based on your door’s weight, height, and track radius. Commercial doors often require custom spring configurations, not off-the-shelf solutions. Professional installation of the correct springs ensures proper balance. It also extends the life of your entire door system.
Step 5: Wind Springs to Proper Tension
New springs must be wound to precise tension specifications by a trained professional. Too little tension and your door won’t open properly. Too much creates unnecessary stress on the opener and other components. Your Facility Door Solutions technician uses calibrated tools and follows manufacturer specifications. This achieves the exact tension required.
Step 6: Balance Testing and Adjustment
After installation, your technician performs balance tests to ensure the door operates smoothly. They’ll disconnect the opener and manually lift the door to verify it stays in place at any height. This confirms the springs are providing the right counterbalance. Final adjustments might include tweaking the opener settings and testing safety features.
Why DIY Garage Door Spring Repair Is Dangerous
You might find online videos showing people replacing their own garage door springs. However, these tutorials dramatically underestimate the risks involved. Torsion springs can store enough energy to cause life-threatening injuries. Even extension springs, while somewhat less hazardous, present serious crush and pinch risks.
Beyond the safety concerns, improper installation creates liability issues for your business. If an incorrectly installed spring causes injury to an employee or customer, your company could face serious legal and financial consequences. Insurance companies typically won’t cover damage or injuries resulting from unlicensed repair work.
Professional technicians carry specialized tools designed specifically for spring work. These tools aren’t available at hardware stores. They also understand local building codes and safety regulations that apply to commercial overhead doors. That expertise protects both your investment and your people.
Extending the Life of Your Garage Door Springs
While springs will eventually need replacement, proper maintenance can extend their service life significantly. Regular lubrication reduces friction and helps avoid rust, especially in coastal or high-humidity areas. Visual inspections catch problems early, before minor issues become major failures. Don’t forget that other components like the garage door bottom seal also require periodic inspection. This keeps your entire door system functioning properly.
A planned maintenance program from Facility Door Solutions includes spring inspection, lubrication, and balance testing. These routine visits help identify springs that are nearing the end of their cycle life. As a result, you can schedule replacement at your convenience rather than dealing with an emergency breakdown. For businesses that depend on overhead door access, this proactive approach minimizes disruption. It also keeps operations running smoothly.
Frequently Asked Questions About Garage Door Spring Repair
How long do garage door springs typically last?
Most commercial torsion springs are rated for approximately 10,000 cycles. This translates to 3-7 years depending on how frequently you use your door. High-cycle springs designed for commercial applications can last longer. However, all springs eventually wear out. Regular maintenance and proper lubrication can help you reach the upper end of that range. On the other hand, neglect or extreme weather conditions might shorten spring life considerably.
Can I just replace one broken spring or do I need to replace both?
Even though only one spring broke, professional technicians typically recommend replacing both springs at the same time. Here’s why: if one spring failed, the other has been through the same number of cycles. It has also experienced the same conditions. It’s likely to fail soon anyway. Replacing both at once saves you from another service call in a few weeks or months. Plus, it ensures your door remains properly balanced.
How much does garage door spring repair typically cost?
The cost varies based on your door size, spring type, and whether you need one or multiple springs replaced. Commercial door springs are larger and more robust than residential springs, so they cost more. However, the investment is worthwhile because professional installation protects your door system, your people, and your business from the risks of improper repair. Contact us today for a specific quote based on your door specifications.
What’s the difference between torsion springs and extension springs?
Torsion springs mount on a shaft above the door and twist to provide lifting force. They’re the most common type on commercial overhead doors. Extension springs stretch along the horizontal tracks on either side of the door. Torsion springs generally last longer and provide smoother operation. That’s why they’re preferred for commercial applications. Both types require professional service for safe repair or replacement. However, torsion springs are particularly dangerous due to the extreme tension involved.
