Broken Garage Door Spring — Signs, Symptoms & What to Do
Loud bang, gap in the spring, door won't lift — these are signs of a broken garage door spring. Do not force it. OnPoint Pro Doors replaces springs same day across NYC, Long Island, and NJ.
How to Tell If Your Garage Door Spring Is Broken
A broken garage door spring is the most common reason a door stops working suddenly. Here are the definitive signs:
Sign 1: You Heard a Loud Bang
A torsion spring stores an enormous amount of energy. When it breaks, it releases that energy instantly with a loud bang — often described as a gunshot or a heavy object falling. This usually happens overnight or when you first use the door in the morning. If you heard a loud bang from the garage, the spring has almost certainly broken.
Sign 2: There Is a Gap in the Spring
Look at the torsion spring above the door. It's a large coiled metal spring on a horizontal bar. A broken spring will have a visible gap — usually 1–3 inches — where the coil has separated. This is the clearest visual confirmation of a break.
Sign 3: The Door Won't Open or Opens Only a Few Inches
The opener motor will try to lift the door but immediately trigger its overload protection because the door is now far too heavy without spring support. The door may open 6–12 inches and then stop. The opener may click repeatedly but not move the door.
Sign 4: The Door Feels Extremely Heavy
Disconnect the opener using the red emergency cord and try to lift the door manually to waist height. A garage door with an intact spring should lift easily and stay in place at any height. A door with a broken spring will feel impossibly heavy — 150–400 lbs — because nothing is counterbalancing it. Do not attempt to lift it if it feels this heavy.
Sign 5: The Door Is Crooked or Tilted
If only one of two springs breaks (extension spring systems have one spring on each side), the door will tilt to one side as it tries to open. This tilting can also cause the door to come off track.
Sign 6: The Cable Is Hanging Loose
When a torsion spring breaks, the drum it winds around loses tension. This causes the lift cables to go slack and hang loosely or pile up on the floor. This is a secondary symptom — the real cause is the broken spring.
Is It Safe to Use a Garage Door With a Broken Spring?
No — never operate a garage door with a broken spring. Without the spring's counterbalance, the door weighs its full panel weight — typically 150 to 400 lbs for a standard residential door. The opener is not designed to handle this load. If you force operation:
- The opener motor can overheat or burn out, adding hundreds of dollars to your repair bill
- The cables can snap under the additional load
- If the door is partially open and the opener fails, the door can fall suddenly
- Trying to lift the door manually without spring support is a serious injury risk

Torsion Springs vs Extension Springs — Which Do You Have?
Torsion springs run horizontally above the door on a metal bar. Most newer homes (built after 1995) use torsion springs. They last approximately 10,000 cycles — roughly 7–9 years with daily use.
Extension springs run horizontally above the horizontal track on each side of the door. Older homes often have extension spring systems. They're typically rated for 7,000–10,000 cycles and are slightly less common in NYC.
We replace both types same day. When one spring breaks, we strongly recommend replacing both — the second spring is the same age and under the same wear, and replacing both at once saves a return service call.
Frequently Asked Questions
How do I know if my garage door spring is broken?
The clearest signs are: a loud bang you heard, a visible gap in the coil spring above the door, the door won't open or only moves a few inches, and the door feels extremely heavy when you try to lift it manually.
Can I replace a garage door spring myself?
This is not recommended. Garage door torsion springs are under extreme tension and can cause serious injury if improperly handled. Professional technicians use specialized winding bars and safety techniques. Spring replacement should always be done by a trained technician.
How much does spring replacement cost in NYC?
Torsion spring replacement typically costs $150–$300 in the NYC area. We recommend replacing both springs at once (same labor cost, longer combined lifespan). Extension spring replacement runs $100–$200 per spring. Call (929) 429-2429 for a free estimate.
How long do garage door springs last?
Standard torsion springs are rated for 10,000 cycles — about 7–9 years with a door used twice daily. High-cycle springs are rated for 20,000–25,000 cycles and last significantly longer. We can upgrade your springs at the time of replacement.
Should I replace both springs or just the broken one?
We strongly recommend replacing both springs when one breaks. The second spring is the same age and under the same wear — it will likely break within weeks or months. Replacing both at once adds minimal cost and prevents a second service call.
