Broken Spring Replacement in Forest Hill, TX
One torsion spring on a double door is wound about seven and a half turns and holds back more than 200 pounds. Let that go without control and it breaks fingers, wrists and jaws. This is the one job on a garage door we ask Forest Hill homeowners not to touch, and we mean it literally.

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.
Why this is the job we tell people to stay off of
The broken spring is not the danger. It already let go. The danger is everything else still loaded. On a two spring door, the other spring is still fully wound. Both bottom brackets are still under the full pull of that counterbalance, which is exactly why the factory puts a warning label on them. Winding a torsion spring takes steel winding bars seated in the cone holes. Wrong size bar, loose set screw, or a hand slipping, and the bar comes out at speed with hundreds of pounds behind it. Emergency rooms see these. They are hand, wrist, face and teeth injuries. People use screwdrivers and rebar because that is what is in the garage, and that is how most of it happens.
Both springs get replaced, not just the broken one
Both springs went on the same day and have taken the exact same number of cycles. When one hits the end, the other is right behind it. Beyond that, springs get sized as a matched pair against the door weight, so a new one working next to a fatigued one puts uneven torque across the shaft and the door never balances properly through its travel. Two service calls also cost more than one. This is not an upsell, it is the reason you are not calling us again in four months.

Please do not attempt this one yourself
That spring is still loaded even with the door down. People get badly hurt trying to unwind one with the wrong tools. Leave the door shut, do not pull the release, and call us.
What you are probably seeing
- Gaps between coils on a spring that has not broken yet, or rust pits in the coil.
- A loud bang from the garage, and the door worked fine right up until then.
- A two to three inch gap in the coil of the spring above the door.
- Opener strains, moves the door a few inches, then stops or reverses.
- Door is extremely heavy by hand and will not stay up.

How a Forest Hill 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 Forest Hill
Can I replace a torsion spring myself?
No. That is the one flat no on this whole site. It takes correctly sized steel winding bars, properly seated set screws, and a stance that keeps your body out of the arc of those bars. Improvised tools slipping under that kind of torque send people to the emergency room every year. Almost everything else on a garage door is fair game for a handy person. This is not.
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.
How long will the new springs last?
Take the cycle rating and divide by how many times a day you open the door. A standard 10,000 cycle spring is four to five years at six openings a day, or about fourteen years at two. If your house is on the heavy end, ask about high cycle springs at 20,000 or more. The price difference is small next to a second replacement.
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.
Did I break it?
No. Springs fail from metal fatigue after a counted number of cycles, and they usually go on a cold morning because the steel is less forgiving then. The two things that actually shorten spring life are a spring undersized for the door at install and rust pitting on the coil. Neither one is about how you use the door.
