Quick Summary: Key Spring Repair Facts
- Average Cost (Illinois): Homeowners in Mundelein and the Chicago suburbs typically pay between $250 and $450 for a professional spring replacement (parts + labor).
- Safety Warning: NEVER attempt to replace torsion springs yourself unless you are a trained professional. They are under enough tension to cause fatal injuries or severe property damage.
- Broken Spring Signs: A loud “bang” like a gunshot from the garage, the door only opens 2-6 inches, or the door feels incredibly heavy (often 150+ lbs) when lifted manually.
- The “Rule of Two”: If one spring breaks, the other is likely at its cycle limit. Professionals always recommend replacing both springs at once to maintain balance and prevent a second service call a few weeks later.
- Standard Process: Secure the door, unwind remaining tension with professional winding bars, remove the broken spring, install a matching high-cycle replacement, and balance the door.

How to Identify and Repair a Broken Spring
1. Visual Inspection
Look for a visible gap (usually 1–2 inches) in the coil of the torsion spring located on the bar above the door. If you have extension springs (on the sides), look for a snapped or stretched coil.
2. Why Professional Repair is Mandatory
Torsion springs store energy in their coils to lift doors weighing hundreds of pounds. Releasing this tension requires specialized steel winding bars. Using screwdrivers or pliers as a substitute is the #1 cause of DIY garage injuries.
3. The Professional Repair Steps:
- Step 1: Balancing. A tech calculates the door’s weight and selects a spring with the correct IPPT (Inch-Pounds Per Turn).
- Step 2: Winding. The tech applies exactly the right number of turns (usually 7.5 to 8 for a 7ft door) to neutralize the door’s weight.
- Step 3: Hardware Check. While the springs are off, we inspect the center bearing and end plates, which often wear out simultaneously.
Frequently Asked Questions
Can I use my garage door opener if the spring is broken?
NO. Do not pull the opener’s wall button. Without the spring’s help, the opener’s motor or gears will likely burn out or strip, turning a $250 spring repair into a $600 opener replacement.
Torsion vs. Extension: Which is better for Illinois?
Torsion springs are superior for our climate. They are more durable, provide better door balance, and don’t “whip” across the garage if they snap (unlike extension springs which require safety cables).
How long do new springs last?
A standard spring lasts 7–10 years (approx. 10,000 cycles). Our high-cycle springs can last 15–20 years, making them the better long-term investment for busy families in the Northwest Suburbs.
