Garage door spring replacement
A broken spring is the most common reason a door stops working. We size the new spring to your door, balance it, and tell you the price before we start.
Signs it's this
- A loud bang from the garage, like a firecracker, with nobody near the door
- The door lifts a few inches and stops, or the opener hums and strains
- A visible gap in the coiled spring above the door
- The door feels very heavy when you try to lift it by hand
- Cables hanging loose beside the door
Do this now
Stop using the opener and leave the door where it is. A door with a broken spring can weigh 150 to 250 pounds, and springs and cables are under high tension. Don't loosen any bolts on the spring bracket.

- Opener force and travel settings, reset after the new springs go on
- A balance test with the opener disconnected

Ringed in green: the parts this page covers.
1 Torsion spring
Springs are rated for a set number of cycles. When one snaps, the door suddenly weighs 150 to 250 pounds.

2 Cable drum and cables
Cables fray and slip off the drum, and the door hangs crooked or stops partway.
from $149Read the entry
3 Opener motor
The motor hums or clicks but will not lift. Stripped gears and burned boards are common.
from $129Read the entry
4 Track
A bent or loose track throws the rollers out, and the door jams or comes off.
from $149Read the entry
5 Hinges and rollers
Worn rollers grind, wobble and wear the track. Cracked hinges let panels flex.
from $139Read the entry
6 Door photo eyes
Bumped out of line, the safety eyes make the door reverse or refuse to close.
from $120Read the entry
7 Solar panel
Dust, shade and summer heat cut the charge the gate battery needs overnight.
from $149Read the entry
8 Gate control box
Storm surges and heat burn control boards and wear out the backup battery.
from $149Read the entry
9 Gate operator arm
A worn or undersized arm strains and stalls on a long, heavy gate.

10 Gate photo eye, left post
A blocked or misaligned eye stops the gate mid-swing for safety.
from $95Read the entry
11 Gate photo eye, right post
The matching eye on the far post. Both have to see each other.

Parts and options
- Torsion springs
- The coiled springs on a bar above the door. Most doors in Round Rock and Austin use one or two.
- Extension springs
- Springs that run along the horizontal tracks on older or lighter doors. Always replaced as a pair, with safety cables.
- Standard-cycle springs
- Rated for about 10,000 open-and-close cycles. Fine for a door used a few times a day.
- High-cycle springs
- Rated for 20,000 cycles or more. Worth it on a busy family door or a door that is also the front entrance.
- Cables and drums
- Often replaced with springs, because they wear together.
One spring or two?
Your door has a single spring and it broke
Replace the single spring with a correctly sized one.
Your door has two springs and one broke
Replace both. The second spring is the same age and usually fails within months.
The door is heavy, wood or insulated with windows
High-cycle springs are worth the difference.
Cables are frayed or a drum is cracked
Replace them on the same visit. A spring job with worn cables is half a repair.
Why springs break in Central Texas
Springs fail from cycles, not from heat alone, but our long summers mean more trips in and out of an air-conditioned garage, and humid spring storms speed up rust on bare steel. A spring that is rusty or squeaks at the coil is close to the end of its life.

Questions people ask on the phone
How much does garage door spring replacement cost in Round Rock?
A single torsion spring starts at $229 installed and a pair starts at $349. High-cycle pairs start at $549. Extension spring pairs start at $199. You get the exact price in writing before we start.
Can I replace a garage door spring myself?
We don't recommend it. Torsion springs hold enough energy to break bones, and winding bars slip. If you are set on doing it, at least have the springs sized correctly and never loosen the set screws on a wound spring.
How long does a spring replacement take?
Most spring jobs are done in one visit. Extra time goes into checking cables, drums and balance, which is what keeps the new springs from wearing out early.
Will my opener work after the spring is replaced?
Usually, yes. A door with a broken spring can strain an opener, so we test the opener and reset its force and travel limits after the new springs go on.
What warranty comes with new springs?
One year on our labor, and the springs carry their manufacturer warranty.
