Broken Spring Repair in Preston Hollow, Dallas, TX
A torsion spring on a standard double door is wound roughly seven and a half turns and holds enough torque to counterbalance 200 pounds or more. Released without control, that energy breaks fingers, wrists, and jaws, and the tools involved become projectiles. This is the one repair on a garage door that we ask Preston Hollow, Dallas homeowners not to attempt, and we mean it literally rather than as a sales position.

How a torsion spring stores and returns energy
A torsion spring sits on a steel shaft above the door opening. Installing it means winding it a specific number of turns, commonly around seven and a half for a seven foot door, which twists the spring steel and stores mechanical energy in it. Cables run from drums at each end of that shaft down to brackets at the bottom corners of the door. As the door closes, the door's own weight winds the spring tighter; as it opens, the spring unwinds and returns that stored energy to the drums, which pull the cables and lift the door. The system is designed so that the spring's torque and the door's weight cancel out, which is why a healthy door can be lifted with about ten pounds of hand effort despite weighing well over a hundred.
Torsion and extension springs are different systems
Torsion springs mount on a shaft above the opening and are standard on most doors installed in the last few decades. Extension springs run horizontally along the tracks on each side, stretch as the door closes, and contract to help lift it. Extension springs are still common on older and lighter doors, and they carry a specific hazard: without a safety cable threaded through the center of the spring and anchored at both ends, a failing extension spring becomes a whipping length of steel across the garage. If your door has extension springs and no safety cables, adding them is inexpensive and we will recommend it whether or not the spring has failed.
Why we replace both springs, not just the broken one
On a two spring door, both springs were installed on the same day and have taken the same number of cycles. When one reaches the end of its fatigue life, the other is within a short distance of the same point. Replacing only the failed spring gives you a door with one new spring and one old one, an unequal torque distribution across the shaft, and a second service call in the near future for the same problem. There is also a sizing consequence: springs are selected as a matched pair for the door weight, and a mismatched pair never balances the door correctly across its travel. Replacing both at once costs less than two visits and produces a door that actually balances.

Please do not attempt this one yourself
A torsion spring holds several hundred pounds of stored energy even when the door is down. Releasing that energy without the correct winding bars is how people lose fingers. If a spring has snapped, leave the door closed and call us.
What you are probably seeing
- A gap has opened between coils on an intact spring, or the coils show rust pitting.
- A loud bang from the garage, often heard from inside the house, with the door working fine right up until that moment.
- A visible gap of two to three inches in the coil of the spring above the door.
- The opener strains, moves the door a few inches, and stops or reverses.
- The door is extremely heavy to lift by hand and will not stay up when released.

How a Preston Hollow, Dallas call runs
Confirm the failure and secure the door
We identify which spring broke, check whether the intact spring is still under load, and secure the door so it cannot move while work is underway. The opener stays disconnected for the duration.
Measure the door and the existing springs
Wire diameter, inside diameter, length, and wind direction are recorded from the existing springs, and the door weight is established. Those numbers determine the replacement rather than a visual match.
Controlled removal
Any remaining tension is unwound with proper winding bars, cables are released from the drums, and the old springs come off the shaft. Bearings, drums, and the shaft itself are inspected while they are accessible, since this is the only convenient time to see them.
Install and wind to calculated turns
New springs of the correct specification are installed as a pair, cables are set in the drums with equal tension so the door lifts square, and the springs are wound to the turn count the door requires rather than to a default.
Balance test and opener reset
The door is lifted by hand and checked at several points in travel to confirm it holds position. The opener is reconnected, travel and force are reset to the corrected door, and the safety reversal is tested.

Questions
Broken Spring Repair in Preston Hollow, Dallas
Can I replace a torsion spring myself?
We will not encourage it, and this is the one place on this site where the recommendation is unqualified. Winding a torsion spring requires correctly sized steel winding bars, properly seated cone set screws, and a technique that keeps your body out of the arc of the bars. Improvised tools slipping under several hundred pounds of torque cause hand, wrist, and facial injuries every year. Almost everything else on a garage door is a reasonable DIY project. This is not.
Why do I have to replace both springs?
Because both have taken the same number of cycles and the second one is close behind the first. Beyond that, springs are sized as a matched pair against the door weight, and a new spring paired with a fatigued one distributes torque unevenly across the shaft, so the door never balances properly through its travel. Two visits also cost more than one.
Did I do something to cause this?
Almost certainly not. Springs fail from metal fatigue accumulated over a counted number of cycles, and the failure typically lands on a cold morning because the steel is slightly less forgiving then. The two things that genuinely shorten spring life are a spring undersized for the door at installation and corrosion pitting on the coil, and neither is caused by how you use the door.
Will you replace the cables at the same time?
We inspect them and tell you what we find. Cables that show fraying at the drum wrap or at the bottom bracket are worth replacing while the spring work already has the system apart, because the labor overlaps almost entirely. Cables in good condition do not need replacing simply because a spring failed.
Does a broken spring damage the opener?
Running the door on a broken spring will, given enough attempts. The opener suddenly has to move the full weight of the door, and what fails is the drive gear, the trolley, the opener arm, or the top section where the arm attaches. One or two attempts before you realize what happened is usually harmless. Repeated cycling is not.
