Torsion and extension · Do not wind these yourself
Garage Door Spring Repair in Texas
Garage door spring repair is usually a spring replacement. The spring is what makes a heavy door feel liftable. When it breaks, the door becomes the weight it always was, and the opener should not be asked to pretend otherwise.
Leave the winding cones alone
Torsion springs are under high tension. Winding bars, the cones, and the shaft are not a weekend project. People lose fingers and worse trying to “adjust” them. STCRON Garage Door does not publish winding steps. If a spring broke, stop using the opener, keep clear of the door, and request service.
Search language splits between garage door spring repair and garage door spring replacement. On most residential doors the failed spring is replaced, not welded or patched. Repair, in the way homeowners use the word, means restoring the balance. The part that goes in is a new spring, sized to the door. A second spring on the same shaft is often replaced at the same time, because it has lived the same number of cycles and is likely to follow.
STCRON Garage Door does this work in Texas on homes and, where the hardware matches, on commercial sectional doors. If the door is also off the track or a cable has whipped loose, treat it as emergency garage door repair until the opening is safe.
Torsion springs and extension springs
The door in front of you uses one of these systems. They fail differently and they are not interchangeable by guess.
| Torsion | Extension | |
|---|---|---|
| Where it sits | On a shaft above the door | Along the horizontal tracks, one on each side |
| What a break looks like | A gap in the coil, a bang, sometimes a shaft that looks shifted | A spring stretched into a loose tangle, or a loud release above the track |
| What else to inspect | Cables, drums, center bearing, end bearings | Pulleys, cables, and the safety containment that should be on those springs |
| Typical next page | Cables and drums | Full door inspection |
Warning signs
How a spring announces itself
- A single loud bang from the garage, often compared to a firecracker.
- The door feels suddenly heavy, or the opener hums and does not lift.
- A visible gap in a torsion coil above the door.
- The door rises a few inches and stalls, or it slams when it comes down.
- One side of the door sits higher because one spring is still working.
- Cables that have gone slack or jumped a drum. Stop there and read the cable page. Do not rewind anything.
Heat in a Texas garage does not snap a healthy spring by itself, but a spring that has already used its cycles will pick a hot afternoon as easily as a cold morning. The cycle count is the life. The weather is just present for it.
What the visit covers
We identify torsion or extension, measure the door, and specify a spring for that weight and height rather than matching a color from memory. Bearings, drums, and cables are inspected because a new spring on a frayed cable is a short repair. The opener is checked only after the door is balanced. If the motor was damaged by weeks of lifting a dead spring, that becomes an opener repair or an opener installation, named separately.
Garage door spring replacement cost and garage door spring repair cost vary with door height, whether the system is torsion or extension, and whether one spring or the pair is replaced. We do not print a flat price. You hear the scope before the cones are wound. If the sections and track are failing around the spring, we will say whether replacing the door is the more honest project.
After the spring is in
The door should travel without the opener doing all the work. We run the cycle and the safety reverse. Then we talk about maintenance so rollers and hinges are not ignored until the next bang. Homes with attached garages should also look at residential repair if other symptoms were present. Commercial sectional doors with torsion systems are noted on commercial services.
Broken spring repair is not something to stage with locking pliers and a ladder. If the door is down on a car you need, call. If the door is up and will not stay, keep the opening clear and use the emergency path. General symptoms that are not obviously a spring still belong on garage door repair.

Spring questions
Should both torsion springs be replaced if only one broke?
Often yes. They were installed together and cycled together. Replacing one leaves the older spring as the next failure. We will say if your door is an exception.
Can I open the door manually until you arrive?
If it feels heavy, no. Forcing an unbalanced door, or letting it fall, is how cables and sections get destroyed and how people get hurt. Leave it.
Is a louder spring a sign it is about to break?
Squeaks are often rollers or hinges, not the spring. A gap in the coil or a bang is the spring. If you only have noise, start with maintenance or general repair and mention the sound.
Do you convert extension springs to torsion?
When headroom and the track allow it, conversion can be part of a larger installation or replacement. It is not an automatic add-on to a simple spring swap. We look at the opening first.
Why the pair, the bearings, and the cables are one conversation
A torsion spring rarely lives alone in any way that matters. On a two-spring shaft, the unbroken partner has turned the same number of times. Replacing only the one that snapped leaves a dated spring as the next bang, often within a season. We will say if your door is a single-spring system and the recommendation is different. Bearings at the center and the ends are checked because a new spring wound onto a dry, grinding bearing plate is a short repair. Cables and drums are checked because the spring’s force arrives at the door through those parts. A frayed cable is not a separate errand you discover after we leave. It is part of making the door safe to travel.
Extension springs, the ones running above the horizontal track, fail as a stretch and a release rather than as a gap in a coil over the door. They should have a safety containment so a break does not throw the spring across the garage. If that containment is missing, the replacement scope includes it. We do not reinstall a bare extension spring and call the older setup “how the house came.”
What we will not put in writing as a procedure
You will not find winding counts, bar sizes, or cone directions on this page. Those details are how people get hurt when they are copied without the door in front of them. The correct spring is calculated from the door’s height, width, and weight, and from the drums on that shaft. A spring that looks similar and came from a kit labeled for “a standard two-car door” can be the wrong spring for your drums. Wrong springs make a door that flies open or a door that the opener has to drag. Both feel like a bad installation. Both are avoided by measuring, not by guessing from the curb.
If the opener already died trying to lift the door after the spring broke, we will separate that repair. You should not pay for a new motor until the door is balanced, and you should not be told the motor is fine if it was cooked. Opener repair is the page for that second finding. If the sections are so rusted that a new spring is being asked to balance a door that is coming apart, we will say the money belongs on replacement instead.
The rest of the day, after the door is light again
A balanced door moves without the opener doing all the work. We show you that, with the trolley released, only when it is safe to demonstrate. Then the opener is reconnected, the limits are checked, and the reverse is tested. Lubrication on the spring is a light coat where it belongs, not a dripping mess that collects garage dust. Rollers that screamed because the door was dragging are noted for roller or track work if they are actually flat, not merely loud from the imbalance.
Until we arrive, leave the door where it stopped if it is stable and closed. If it is open and creeping down, keep the opening clear and treat the call as urgent. Do not prop a heavy door with a single board and hope the household remembers. A prop is not a balance system.
After the bang, the household routine
If the door is down and closed, leave the cars outside and use another door into the house. If a car is already inside, leave it there until the door is safe to travel. Do not try to “help” the opener by lifting the middle of a heavy door. People strain their backs and they also rack the sections. If you can unplug the opener from a wall you can reach without crossing under a crooked door, do that so nobody else in the house cycles it out of habit. Then call.
When we finish, ask to see the door move with the opener disconnected, if that demonstration is safe on your door. A door that stays where you stop it, and that does not fly upward, is the balance you paid for. Ask which parts were replaced besides the spring: cables, bearings, drums. Those words should match the scope. If we recommend the second spring on a two-spring shaft, the reason is shared cycle life, and you can decline it knowing the next failure is more likely. We would rather have that conversation in the driveway than imply a one-spring swap is always the complete job.
What “balanced” means when we leave
The door should not slam shut and it should not rocket open when the opener is disconnected, within the careful test we are willing to show you. Cables should sit in the drums. The opener should travel the door without straining, and the reverse should still work. If we replaced one spring on a two-spring shaft, you will have heard why the other one stayed. If we replaced both, the scope will say so. There is no winding tutorial on this website because copying one is how people get hurt. The completed visit is the proof, not a diagram.
Tell us which spring you can see
A photo from the floor of the hardware above the door is enough. Do not climb to the shaft to get a closer one.
