Garage Door Springs in Covina: When to Replace Torsion or Extension Springs
7 min read
In our years serving Covina, we've seen this problem again and again: a homeowner opens their garage one morning, hears a loud bang, and suddenly the door won't budge. That bang is almost always a snapped spring, and it's one of the most common reasons we get emergency calls from frustrated residents. The good news is understanding the signs early can save you money and keep your family safe.
Garage door springs carry all the weight of your door. A typical residential door weighs 300 to 400 pounds. Without springs, the opener motor would burn out in weeks trying to lift that load alone. Springs do the heavy lifting, transferring tension to counterbalance the door's weight. When they fail, nothing moves safely, and you're stuck.
Two Types of Springs: Torsion and Extension
Most Covina homes use one of two spring systems.
Torsion springs sit above your garage door on a horizontal rod. They twist and unwind to lift the door. These are the most common type in modern homes because they last longer and operate more smoothly. A quality torsion spring lasts 7 to 9 years with normal use, or roughly 10,000 to 15,000 cycles. If you open and close your door twice daily, you'll get solid service from a well made spring.
Extension springs hang vertically on each side of the door. They stretch and contract like regular coil springs. These are cheaper upfront but wear out faster, typically lasting 5 to 7 years. They're also more prone to sudden failure because the metal fatigues as it cycles.
Both types fail without warning. There's no gradual slowdown. One day the spring snaps, and your door becomes a 300 pound obstacle you cannot lift by hand.
Warning Signs Your Springs Are Failing
Catch problems early. If you hear grinding, squeaking, or creaking sounds during operation, your springs are under stress. If the door feels heavier than usual when you try to open it manually, a spring is losing tension. The door may also fall faster than normal when closing, indicating a weakened spring on one side.
Never attempt to replace springs yourself. The tension stored in a coiled spring can cause serious injury or death. We've treated homeowners who tried DIY replacement and ended up in the emergency room. This isn't an exaggeration. When a spring unwinds under load, it releases force equivalent to a car collision in a confined space.
The Cost and Timeline for Spring Replacement
Spring replacement cost varies based on the type and quality you choose. A single torsion spring replacement typically runs 150 to 300 dollars, while extension springs cost 100 to 200 dollars each (most doors have two). Labor adds another 200 to 400 dollars depending on complexity. For a detailed breakdown of what affects pricing, check our guide on garage door cost and pricing in Covina.

If both springs are failing, replacement cost doubles. However, it's smart to replace both at the same time even if only one has snapped. The second spring is likely close behind, and replacing one leaves you vulnerable to another breakdown weeks later. Same-day service means you won't be locked out of your garage overnight.
Why Spring Maintenance Matters
Regular lubrication and inspection extend spring life. During a tune-up, a technician applies the right lubricant and checks for rust, corrosion, or early wear signs. Rust weakens metal and accelerates failure, especially in Southern California where humidity and salt air are factors even in inland areas like Covina. If you want a deeper dive into preventive care, read our garage door tune-up and lubrication guide.
Seasonal changes also matter. Springs contract in cold weather and expand in heat. This cycling stresses the metal. If you notice any changes after winter or summer, have springs inspected before they fail.
What to Do When a Spring Snaps
First, stop using the door. Do not try to force it open or closed. Call a professional immediately. We respond to spring emergencies in Covina and nearby areas with same-day availability whenever possible. While you wait, do not let children play near the garage door. A partially raised door can fall unexpectedly if the remaining spring breaks.
When you call, give us a brief description. The door won't open? Both springs failed. The door opens but feels heavy? One spring is likely gone. This helps us arrive prepared with the right parts and tools.
To schedule a free quote or same-day estimate, call us or book online. We'll inspect your springs, confirm the issue, and provide a clear cost estimate before we begin work.
Spring failure is predictable only after it happens. But maintenance and early inspection catch problems before they leave you stranded. Don't wait for the bang.
Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years or 10,000 to 15,000 cycles. Extension springs last 5 to 7 years. Lifespan depends on use frequency, climate, and maintenance. Regular lubrication extends life.
Can I replace a garage door spring myself? No. Springs store dangerous tension that can cause severe injury or death if released improperly. Always hire a licensed professional. DIY replacement is not worth the risk to your safety.
Why is spring replacement so expensive? Labor costs are high because the job requires specialized tools and technical skill. Springs themselves are inexpensive, but safely replacing them under high tension demands expertise and liability insurance. Professional service protects you.
What's the difference between torsion and extension springs? Torsion springs sit horizontally above the door and twist. Extension springs hang vertically and stretch. Torsion springs last longer and are more common in modern homes. Extension springs are cheaper but wear faster.
Will my garage door opener work without springs? No. The opener cannot lift the door's full weight alone. Without springs, the opener motor will burn out or the door will not move. Springs are essential for safe, reliable operation.
