How to Tell If Your Garage Door Spring Is Broken (And What to Do)

Your garage door worked fine last night. This morning you press the button and — nothing. Or it opens a few inches and stops. Or you hear a loud bang from the garage. Nine times out of ten, you've got a broken spring.

Here's everything Long Island homeowners need to know about broken garage door springs — the signs, the dangers, and what it costs to fix.

The Warning Signs of a Broken Garage Door Spring

1. The Door Won't Open At All

Springs do the heavy lifting. A standard two-car garage door weighs 200–400 lbs. Without working springs, your opener motor simply can't lift it. If your door won't move and your opener is humming or straining, a broken spring is the most likely cause.

2. You Heard a Loud Bang

Torsion springs (the horizontal springs above your door) are under extreme tension. When they break, they release all that energy at once — creating a loud bang that sounds like a gunshot. If you heard this from your garage, don't go in until a technician checks it.

3. The Door Looks Crooked or Uneven

Most doors have two springs. If only one breaks, the door will hang lower on one side, making it look tilted or off-track when you try to open it.

4. The Top Section of the Door Bends

When an opener tries to lift a door without spring support, it sometimes bends the top panels inward. This is a sign of a broken or severely weakened spring.

5. There's a Gap in the Spring

Look at the torsion spring above your door. If you can see a visible gap — usually 2–3 inches wide — the spring has snapped. This is the clearest sign of a broken spring.

Types of Garage Door Springs

Torsion Springs

The most common type on Long Island homes. These mount horizontally above the door and wind/unwind to lift the door. They last 10,000–20,000 cycles (roughly 7–14 years with daily use).

Extension Springs

These run along the horizontal tracks on either side of the door. Less common in newer homes. They're under high tension and can cause serious injury if they snap without a safety cable.

What Does Garage Door Spring Repair Cost on Long Island?

Can I Replace a Garage Door Spring Myself?

Technically yes. Practically — no. Garage door springs are under hundreds of pounds of tension. Improper release of that tension can cause the spring to whip, causing serious injury or death. Every year, homeowners are seriously injured attempting DIY spring replacement.

For a $150–$400 repair, it's not worth the risk. Call a licensed technician.

How Long Does Spring Replacement Take?

A professional technician can replace one or both springs in 1–2 hours. At Garavex, we carry springs for all major door brands in our trucks — no waiting for parts.

How Long Will New Springs Last?

Standard springs last 10,000 cycles. Heavy-duty springs last 25,000–50,000 cycles. If you want springs that last longer, ask about upgrading to high-cycle springs — they cost slightly more but last 2–5x longer.
