Broken Spring Replacement in Granbury, TX
A spring replacement is a bounded job with a known price once we see the door. What costs real money is running the door after the spring broke. That puts the whole weight on the opener, the shaft and the cables, and in Granbury a spring call turns into a spring, gear and cable call.

What the spring is actually doing up there
The torsion spring sits on a steel shaft above the opening. When it gets installed, it gets wound a set number of turns, usually around seven and a half on a seven foot door. That twist is stored energy. Cables run from drums on each end of the shaft down to brackets at the bottom corners of the door. Closing the door winds the spring tighter. Opening it lets the spring unwind and pull those cables. The whole design is a trade: the spring's torque cancels out the door's weight. That is why a 200 pound door lifts with about ten pounds of hand effort when everything is right.
Torsion and extension springs are two different systems
Torsion springs sit on a shaft above the door. That is what most doors built in the last few decades use. Extension springs run along the horizontal tracks on both sides, stretch when the door closes, and pull back to help lift it. Plenty of older and lighter doors still have them. Here is the part that matters: an extension spring needs a safety cable run through the middle of it and anchored at both ends. Without that cable, a spring that snaps becomes a length of steel whipping across your garage. If your door has extension springs and no safety cables, we will put them in. They are cheap.
Sizing is measuring, not eyeballing
A torsion spring is defined by four things: wire diameter, inside diameter, length, and which way it winds. Those decide how much torque you get per turn. Picking the replacement means knowing what the door weighs, either by putting it on a scale with the springs off or by calculating from the panel construction and hardware. Too light a spring and the door stays heavy at the floor and burns through cycles fast. Too heavy and the door wants to fly open and the opener fights it all the way down. Both feel more or less fine on day one. Both cut the life of everything they are bolted to.

How a Granbury call runs
Confirm it and secure the door
We find which spring broke, check whether the other one is still loaded, and clamp or block the door so it cannot move while we work. Opener stays disconnected the whole time.
Measure the door and the old springs
Wire diameter, inside diameter, length and wind direction come off the existing springs, and we establish what the door weighs. That decides the replacement. Not a visual match.
Unwind and strip it
Any leftover tension comes off with proper winding bars, cables come off the drums, old springs come off the shaft. We check the bearings, drums and shaft while we can actually see them.
New pair, wound to the right turn count
Both springs go on. Cables get set in the drums with equal tension so the door lifts square. Springs get wound to the turns this door needs, not to a default number.
Balance by hand, then reset the opener
Door gets lifted by hand and checked at several heights to make sure it holds position. Then the opener goes back on, travel and force get reset, and we test the safety reverse.

Questions
Broken Spring Replacement in Granbury
Why do both springs have to go?
Same install date, same cycle count, so the second one is close behind the first. And springs get sized as a pair against the door weight, so a new one next to an old one never balances the door right through its travel. Doing it once costs less than doing it twice.
Can I get my car out before you arrive?
Sometimes, carefully, with help. With the opener released the door weighs everything it weighs, often over 200 pounds on a double. Two adults can usually manage it. Block it open with something solid, never with a person holding it, while the car comes out. Do not run the opener, because that is how a spring job turns into a spring, cable and opener job.
Should the cables be done at the same time?
Only if they need it, and we will show you. If the cable is fraying at the drum or at the bottom bracket, do it now, because the labor overlaps almost completely and you save a whole visit. If the cables are clean, leave them alone. A spring breaking does not damage a good cable.
Does a broken spring wreck the opener?
Running the door on it will, given enough tries. The opener suddenly has to move the full weight, and what gives out is the drive gear, the trolley, the arm, or the top panel where the arm attaches. One or two presses before you figured out what happened is usually harmless. Twenty is not.
Do you have springs on the truck?
The common residential wire sizes and lengths, yes, so most jobs get done on the first visit. Unusual sizes, very heavy custom doors, and some high cycle setups occasionally have to be ordered. If yours is one of those, you hear it at the diagnosis, not later.
