Broken Spring Repair in McKinney, TX
A spring replacement in McKinney is a bounded, predictable job, and it is dramatically cheaper than the damage caused by continuing to run the door on a broken one. Cycling a door with one failed spring loads the shaft, the drums, and the opener with weight none of them were designed to carry, and that is how a spring failure turns into an opener and cable failure.

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.
Cycle life, and what the numbers actually mean
A cycle is one full open and one full close. Standard springs are commonly rated at 10,000 cycles. High cycle springs, built with heavier wire and greater length, are available at 20,000, 25,000, and higher ratings. The arithmetic is worth doing for your own household. A family using the garage as the main entrance easily runs six cycles a day, which is about 2,190 a year, which spends a 10,000 cycle spring in roughly four and a half years. A retired couple using it twice a day is looking at closer to fourteen years on the same spring. Neither is a defect. If your door failed early, the useful question is whether the spring was correctly sized for the door in the first place.
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 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.
- The door rises crooked, with one side lagging behind the other.

How a McKinney 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 McKinney
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.
Can I still get my car out with a broken spring?
Sometimes, with help, and carefully. With the opener released, the door weighs its full weight, which on a double door is often over 200 pounds. Two adults can usually manage it and it should be propped securely with something solid, never a person's hands, while a vehicle passes underneath. Do not run the opener, because that is how a spring failure becomes a cable, drum, and opener failure.
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.
Do you carry springs on the truck or does it take a second visit?
Common residential wire sizes and lengths are carried, so the large majority of replacements are completed on the first visit. Unusual sizes, very heavy custom doors, and some high cycle configurations occasionally need to be ordered, and we tell you at diagnosis if yours is one of them.
