You can usually tell a garage door spring is broken by a loud bang from the garage, a door that suddenly feels very heavy or won't open, a visible gap in the torsion spring above the door, or an opener that strains and gives up. If you notice any of these, stop using the door — the spring carries the door's weight, and running it on a broken spring can cause more damage or injury.
What the springs actually do
Garage door springs do the heavy lifting — literally. They counterbalance the weight of the door so the opener (or you) only has to overcome a few pounds of force. Most doors use torsion springs mounted on a bar above the opening; some older or lighter doors use extension springs that run along the tracks. Either way, when a spring fails, that counterbalance disappears and the full weight of the door drops onto everything else.
The signs your spring is broken
Listen and look for these tell-tale signs: a loud bang or pop while the garage was quiet (springs often fail at rest), a roughly two-inch gap in the torsion spring coil above the door, or a door that won't open at all with the opener.
If you disconnect the opener and try to lift the door by hand, a door with a broken spring will feel extremely heavy and may slam back down. You might also see the door open a few inches and stop, hang crooked, or watch the opener strain, struggle, and reverse.
Why you shouldn't keep using it
Running the opener on a broken spring forces the motor to lift a load it was never meant to carry, which can burn out the opener and stretch or snap the cables. A door that isn't counter-balanced can also fall fast if a cable lets go. The safe move is to stop, leave the door closed if you can, and schedule a repair.
What replacement involves
A technician sizes the correct spring to your door's exact weight and replaces springs in pairs so they wear evenly. Most replacements are done on-site in about an hour, including balancing the door by hand and running a full cycle test. We carry full spring sets on every truck and respond the same day across Southeast Texas.
Frequently asked questions
- Can I replace a garage door spring myself?
- We strongly recommend against it. Torsion springs are wound under extreme tension, and a slip can cause serious injury. The job needs the right winding bars, the correctly sized spring, and experience — it's not a typical DIY repair.
- How long do garage door springs last?
- Standard springs are rated for around 10,000 cycles — roughly 7 years of typical use. High-cycle springs can last about twice as long. Replacing both springs at once avoids a second failure soon after.
