Full breakdown and method: Long Island garage door price survey.
Signs your garage door spring broke
- A loud bang from the garage, often on a cold morning.
- A visible gap in the coil of the spring on the bar above the door.
- The opener runs but the door lifts a few inches and stops, or doesn’t move.
- The door feels far too heavy to lift by hand.
- Cables hanging loose at the bottom corners of the door.
If any of these fit, leave the door where it is. A sectional door can weigh well over 100 pounds; the springs are what make it feel light.
Torsion vs extension springs
Torsion springs sit on a steel bar above the door and twist to store energy. They’re the standard on most two-car doors and newer single doors. Extension springs run along the horizontal tracks on each side and stretch. You’ll still find them on many older Long Island single-car doors.
| Torsion | Extension | |
|---|---|---|
| Where | On a bar above the door | Along each side track |
| Published LI price (pair) | $200 – $475 | $140 – $325 |
| Common on | Most two-car and newer doors | Older and lighter single doors |
| Safety note | Must be wound with proper bars | Needs a safety cable through each spring |
If your extension springs keep breaking, or the door is heavy, a conversion to torsion runs $450 – $850 on published Long Island prices.
One spring or both?
Two-spring doors wear both springs together. Replacing only the broken one saves a little today, but the other spring is near the end of its life and the door may run unbalanced. The published median for one spring is $275 and for both is $340. That difference is usually less than a second visit.
How long will your springs last? The cycle math
Springs are rated in cycles: one open plus one close. Standard torsion springs are commonly rated around 10,000 cycles. Here’s what that means in years, at a steady daily use:
| Opens and closes per day | Years to 10,000 cycles | Years to 25,000 cycles |
|---|---|---|
| 2 | about 13.7 | about 34 |
| 4 | about 6.8 | about 17 |
| 6 | about 4.6 | about 11.4 |
| 8 | about 3.4 | about 8.6 |
If the garage is your family’s main way in and out, you can be at 6–8 cycles a day, and a standard spring can wear out in under five years. On one published Long Island price list, a high-cycle pair cost $50 more than a standard pair. Salt air near the water adds rust, which shortens spring life further.
How to read your spring before you call
You don’t need to touch the spring. From the floor, with a phone flashlight:
- Count the springs on the bar above the door: one or two.
- Look for the gap. A broken torsion spring shows a 1–2 inch gap in the coil.
- Check the color. Some manufacturers color-code the winding cones or paint a stripe that marks the wire size.
- Take a photo of the springs, the cable drums at each end, and any label on the door.
That photo lets a tech bring the right size spring the first time.
High-cycle springs: worth it?
Standard springs are commonly rated around 10,000 cycles. High-cycle springs are rated for more and cost a bit more up front. If your garage is the main way in and out of the house, they’re usually worth asking about.
What a proper spring job includes
- Matching the spring wire size, length and inside diameter to your door’s weight and height.
- Checking cables, drums and bearings while the tension is off. Worn cables often get replaced at the same time ($150 – $195 published).
- Winding to the right number of turns, then a balance test: the door should stay put when lifted halfway.
- An opener force and reverse test.

Frequently asked questions
How do I know my garage door spring is broken?
Look at the bar above the door. A broken torsion spring shows a 1–2 inch gap in the coil. Other signs: you heard a loud bang from the garage, the door is very heavy by hand, the opener strains or the door goes up a few inches and stops.
Should I replace one garage door spring or both?
If your door has two springs, replace both. They've done the same number of cycles, so the second usually fails soon after the first. On published Long Island prices the pair ran $200 – $475, versus $175 – $450 for one.
How long do garage door springs last?
Standard torsion springs are commonly rated around 10,000 cycles. One open and one close is one cycle, so a door used four times a day reaches that in about seven years. High-cycle springs last longer and cost a little more.
Can I use my garage door with a broken spring?
No. The springs lift the door; the opener only guides it. Running the opener can strip its gear, and lifting by hand risks the door falling. Leave it closed if you can.
How much does it cost to convert extension springs to torsion?
Published Long Island prices for an extension-to-torsion conversion ran $450 – $850. It comes up most on older single-car doors; about 66% of Nassau homes predate 1960 (Census ACS 2020–2024).
Why are garage door springs cheaper online than a repair visit?
The spring is a small part of the price. You're paying for the right size and wire gauge for your door's weight, safe winding with proper bars, cables and balance checks, and a warranty. Winding a torsion spring without training is dangerous.
