Duncanville, Dallas County
Broken Spring Repair in Duncanville, TX
The first cold snap of the season reliably breaks springs across North Texas. Steel contracts and loses a small amount of ductility, so a spring already near the end of its cycle life fails on the coldest morning rather than on a mild one. If yours went on the first freezing night in Duncanville, that is not a coincidence and it is not something you did wrong.

Why a broken one is dangerous to work on
The danger is not the broken spring, which has already released. The danger is everything else still under load. On a two spring door, the intact spring is still fully wound. The cables are still anchored to bottom brackets that are under the full tension of that counterbalance, which is why those brackets carry a warning label from the factory. Winding or unwinding a torsion spring is done with steel winding bars inserted into the holes of the winding cone; if a bar is the wrong diameter, if the set screws are not properly seated, or if a hand slips, the bar comes out of the cone at speed with several hundred pounds of torque behind it. Emergency departments see these injuries regularly, and they are typically hand, wrist, facial, and dental. Screwdrivers and lengths of rebar used in place of proper winding bars are how most of them happen.
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 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.
- The top section flexes or bends when the opener tries to lift the door.

How a Duncanville 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 Duncanville
How long should a new spring last?
Divide the spring's cycle rating by your daily cycles and multiply out. A standard 10,000 cycle spring lasts roughly four to five years at six cycles a day, or fourteen years at two. If your household is at the high end of usage, high cycle springs at 20,000 or more are a reasonable upgrade and the price difference is modest relative to a second replacement.
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.
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.
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.
