Garage Door Springs in Covina: Torsion vs. Extension and When to Repair
2026-05-20 7 min read A2Z Garage Doors
Your garage door springs are under constant tension, holding hundreds of pounds of weight. When one snaps, your door won't open, and you'll need fast repair. The two main types are torsion and extension springs. Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch to do the same work. Knowing which one you have helps you understand the repair cost and timeline.
Torsion vs. Extension: What's the Real Difference?
Torsion springs are the heavy hitters. They're mounted horizontally above your garage door opening and work by rotating (twisting) to store and release energy. Most modern garage doors in Covina use torsion springs because they're more durable, safer, and last longer. A quality torsion spring typically lasts 7 to 9 years with normal use.
Extension springs attach to the sides of your door frame and stretch like rubber bands. They're cheaper upfront and common on older garage doors or lighter doors. The trade-off is they wear out faster, usually lasting 4 to 7 years, and they're more prone to sudden failure.
Here's the honest part: if you have extension springs, replace both at the same time, even if only one snapped. They wear together, and the surviving spring will fail soon after. With torsion springs, the same rule applies. One spring failure almost always signals the other is on its way out.
Why Springs Fail (It's Not Random)
Garage door springs fail because of metal fatigue. Every time your door opens and closes, the spring cycles. A typical door cycles 1,000 to 1,500 times per year. Over 7 to 9 years, that's 10,000 cycles or more. Metal has a lifespan under stress, and springs eventually reach their limit.
Weather plays a role too. Covina's hot, dry summers and occasional cold snaps cause metal to expand and contract. Rust and corrosion weaken springs faster if they're not maintained. Lack of lubrication increases friction and accelerates wear.
If you want to extend spring life, follow our essential garage door maintenance guide. Regular inspection and light lubrication can add a year or two to your springs' lifespan.

The Real Cost of Spring Repair
Spring replacement cost depends on the type, quality, and whether you need one or both springs. A single torsion spring typically runs $150 to $300 in parts and labor. Extension springs are cheaper, around $100 to $200 per spring. If both springs need replacement, expect $250 to $500 total.
Those numbers assume a reputable local technician. We've seen inflated quotes from larger chains, especially when they push you to replace the whole door. That's not necessary. A snapped spring is fixable.
Labor takes 1 to 2 hours. A qualified technician will inspect both springs, check the cables, and test the door balance before calling the job done. If you need a same-day estimate, schedule a free quote and we'll walk you through the options.
When to DIY vs. Call a Pro
Do not attempt spring replacement yourself. Garage door springs are under extreme tension. A snapped spring can cause serious injury if mishandled. Even professionals use specialized tools and safety equipment. Leave this to someone with experience.
What you can do: listen for the snap (a loud bang), stop using the door, and call a technician right away. If your door is stuck open or closed, don't force it. Forcing a door with a broken spring risks damage to the opener and tracks.
Check our garage door spring warning signs guide to catch problems early. If your door is moving slowly, creaking loudly, or tilting, springs may be wearing out. Early detection saves money.

Frequently Asked Questions
How long do garage door springs last? Torsion springs last 7 to 9 years under normal use (about 1,000 to 1,500 cycles per year). Extension springs wear faster, typically 4 to 7 years. Lifespan depends on maintenance, climate, and usage frequency.
Can I replace just one spring? You can, but we don't recommend it. Springs wear together. If one has failed, the other is near the end of its life and will likely break within weeks. Replacing both costs only slightly more and saves future downtime.
What's the difference between a snapped spring and a stretched spring? A snapped spring breaks completely and the door won't open. A stretched spring weakens gradually, causing the door to move slowly or unevenly. Both need replacement, but stretching is easier to catch early with routine maintenance.
How much does spring replacement cost in Covina? Torsion springs run $150 to $300 per spring with labor. Extension springs cost $100 to $200 per spring. If both springs need replacement, expect $250 to $500 total. Call for a free quote.
Is a broken garage door spring an emergency? Yes. A broken spring leaves your door stuck and your garage inaccessible. It can also damage the opener if you try to force the door. We offer same-day service for spring repairs across Covina.
