A snapped garage door spring will stop your door dead in its tracks, and no opener in the world can force it open. If you've wrestled with a stuck or unbalanced door, the culprit is almost always a broken spring. Understanding what type of spring you have, how long it should last, and when replacement is non-negotiable will save you frustration and money.
Your garage door relies on one of two spring systems, and knowing which one you have matters for repair costs and safety.
Torsion springs wind tightly around a metal rod above your door. They store and release energy as the door moves up and down. Most modern homes in Benicia and the surrounding Bay Area use torsion springs because they're more durable and safer to handle. When a torsion spring fails, the door won't budge without manual force or a backup battery system.
Extension springs run along the sides of your door frame and stretch as the door lowers. They're cheaper upfront but wear out faster, typically lasting 7 to 9 years compared to torsion springs which often reach 10 to 15 years. Extension springs also pose a higher safety risk because they can snap violently and cause injury.
Springs don't last forever. Most quality torsion springs handle 10,000 to 20,000 cycles (one cycle equals one complete open and close). For an average household opening the door 4 times daily, that's roughly 10 to 15 years of service life. Extension springs typically give you 7 to 9 years.
Several factors shorten lifespan. Humidity and salt air near the coast accelerate rust. Infrequent maintenance allows dirt and grime to build up, increasing friction. Extreme temperature swings cause metal to expand and contract unevenly, stressing the springs. If you live near the water in areas like Vallejo or Benicia proper, corrosion is a real threat.
A snapped spring announces itself loudly. You'll hear a bang or crack, and the door will hang crookedly on one side. But earlier warning signs appear long before catastrophic failure.
Listen for squeaking or squealing sounds during operation. Watch for the door moving slowly or unevenly, especially when opening. If your door feels heavier than usual or the opener struggles, a weakening spring is likely the cause. Some doors develop a slight wobble or tilt toward one side as springs lose tension.
Never ignore these signals. A failing spring puts extra strain on your opener and can cause it to burn out prematurely. Learn when spring repair makes sense versus full replacement to avoid costly follow-up repairs.

This is where many homeowners make a dangerous mistake. Spring replacement looks straightforward online, but it's genuinely hazardous. Springs are under tremendous tension. A slip or miscalculation can cause the rod to whip, break bones, or cause serious lacerations. We've treated customers who ignored this advice and paid the price.
Professional technicians have the right tools, knowledge of spring tension calculations for your specific door weight, and insurance coverage. A proper replacement takes 1 to 2 hours and includes testing to ensure balanced operation. Get a same-day estimate for your spring replacement rather than risking injury or an improper installation that fails within months.
Spring replacement cost varies based on spring type, door weight, and whether one or both springs need work. A single torsion spring typically runs between $150 and $250 in parts and labor. Extension springs are cheaper, usually $100 to $180. If both springs have failed (common when they're similarly aged), you're looking at a higher total.
Your door's weight and size matter too. A heavy custom wood door needs stronger springs than a standard lightweight aluminum door. Review our detailed pricing guide to understand what actually drives garage door costs.
Spring failure is one of the few garage door problems that demands immediate professional service. Don't try to open a door with a broken spring by forcing it, and don't ignore warning signs hoping they'll resolve on their own. Broken springs only get worse.

How do I know if my garage door spring is broken? Listen for a loud bang or crack during operation. A broken spring causes the door to hang unevenly, open slowly, or not open at all. The door may feel much heavier than normal. Never attempt to force it open.
Can I replace a garage door spring myself? Springs are under extreme tension and can cause serious injury or death if mishandled. Professional replacement is the only safe option. Improper installation can damage your opener and door frame within weeks.
How much does a garage door spring replacement cost? Torsion springs typically cost $150 to $250 including labor. Extension springs run $100 to $180. Prices vary based on door weight, size, and whether one or both springs need replacement.
How long do garage door springs last? Torsion springs usually last 10 to 15 years. Extension springs typically last 7 to 9 years. Heavy use, humidity, and lack of maintenance can shorten lifespan significantly.
What's the difference between torsion and extension springs? Torsion springs wind around a rod above the door and are more durable and safer. Extension springs run along the sides, wear out faster, and pose greater safety risks if they snap unexpectedly.
