Usually both. They were installed together and have done the same number of cycles, so the second one is close behind.

On a standard door, replacing two springs usually takes 30 minutes to an hour. Converting spring types takes longer.
Symptoms
Signs your garage door spring is broken
A broken spring is the most common reason a garage door suddenly won’t open. Look for any of these:
- A loud bang from the garage, often with nobody near the door. That’s the spring letting go.
- A gap in the coil of the spring on the bar above the door. A healthy torsion spring is one continuous coil.
- The door opens 6 inches and stops, or the opener strains, hums, or reverses.
- The door feels very heavy when you try to lift it by hand.
- The door goes up crooked or one cable hangs loose.
- The door slams shut instead of closing smoothly.
If you see any of these, leave the door where it is and stop pressing the opener. Running the opener against a door with a broken spring can strip its gear or bend the top section.
Spring types
Torsion springs vs extension springs
Most Spring Hill homes built in the last 20 years have torsion springs, but some doors, especially on older or lighter single-car doors, use extension springs.
| Torsion springs | Extension springs | |
|---|---|---|
| Where they are | On a metal bar above the door opening | Along the horizontal tracks on each side |
| Typical rated life | 10,000–20,000 cycles (about 8–15 years) | 8,000–15,000 cycles (about 7–12 years) |
| How they fail | Snap with a loud bang; the door won’t lift | Stretch out or snap; can whip if there’s no safety cable |
| What to check | Coil gap, cable tension, drums, bearings | Safety cables threaded through each spring |

Local factors
Why springs break in Spring Hill homes
The math of cycles
A family that opens and closes the door four times a day puts about 1,460 cycles a year on its springs. At that pace, a standard 10,000-cycle spring lasts roughly seven years. Households with teenagers, a home gym in the garage, or a door used as the front door wear springs out faster.
Growth-era homes and Tennessee weather
Spring Hill grew from about 29,000 people in 2010 to more than 50,000 by 2020, so many doors in neighborhoods like Wades Grove, Benevento, and Harvest Point were installed within a few years of each other, often with standard builder-grade springs. Add January lows around 28°F and about 55 inches of rain a year, and worn, rusty springs tend to give out in cold snaps.
On the job
What we do on a spring repair
- Make the door safe and secure it before touching the spring.
- Size the new springs by wire gauge, inside diameter, and length, matched to your door’s weight. A wrong-size spring leaves the door unbalanced and wears out the opener.
- Replace both springs unless you choose otherwise after we explain why.
- Check the parts that fail with springs: lift cables, cable drums, center and end bearings, and rollers.
- Balance test: with the opener disconnected, the door should stay put about halfway up.
- Safety test: photo-eye sensors and auto-reverse checked before we leave.
Want springs that last longer? Ask about high-cycle springs. They cost more up front and are rated for more cycles than standard springs.
Safety
Why spring replacement isn’t a DIY job
A torsion spring holds enough tension to lift a door that can weigh well over 100 pounds. Winding one takes winding bars, the right spring size, and a set procedure; a slipped bar or wrong-size spring is how people get hurt. The parts are cheap online, but the risk isn’t worth it. If you’re unsure what you’re looking at, describe what you see and we’ll tell you what it likely is.
FAQ
Garage door spring repair FAQs
How much does garage door spring repair cost in Spring Hill, TN?
A single torsion spring replacement typically runs $150–$350 in the Franklin and Spring Hill area. Two springs, high-cycle springs, or a heavy insulated door push the price up. You’ll get a written price before we start.
Should I replace both springs if only one broke?
Usually, yes. Both springs were installed together and have done the same number of cycles, so the second one is close behind. Replacing both keeps the door balanced and saves you a second service call.
Can I open my garage door with a broken spring?
It isn’t safe. Without a working spring, the door’s full weight is unsupported and it can drop suddenly. Leave it closed, don’t pull the emergency release on a raised door, and call a technician.
How long do garage door springs last?
Torsion springs are typically rated for 10,000–20,000 cycles, about 8–15 years for most families. Extension springs are rated for 8,000–15,000 cycles, roughly 7–12 years.
Why did my spring break in cold weather?
Springs that are near the end of their cycle life are the ones that give out, and cold weather is hard on worn, rusty steel. That’s why breakages tend to bunch up during winter cold snaps.
Is a $100 spring repair offer real?
It rarely covers a properly sized spring, both springs, and labor on a two-car door. The BBB warns that some companies advertise a low call-out fee, then inflate the work once they’re in your garage. Ask for the full price in writing before any work.
