Your garage door was working fine yesterday. This morning it won't budge. or it opened halfway and stopped, or you heard a loud bang from the garage that sounded like a gunshot. If any of that sounds familiar, there's a very good chance you have a broken garage door spring.
It's one of the most common repair calls we get in San Leandro and across the East Bay, and it's also one of the most misunderstood. Homeowners often underestimate how serious. and how dangerous. a failed spring actually is. This guide gives you an honest look at what's going on, what it typically costs, and what questions to ask before anyone touches your door.
Garage door springs are rated by cycles. one cycle equals one full open-and-close of the door. Most standard springs are rated for 10,000 to 20,000 cycles. For a family that uses the garage as the main entry point (which is most San Leandro households, given how few front-door-focused the older ranch homes and bungalows in neighborhoods like Washington Manor and Broadmoor tend to be), you can burn through 1,500 cycles a year easily.
That alone makes spring replacement a near-certainty every 7,12 years. But in the Bay Area, there's an added factor: humidity. San Leandro's year-round relative humidity sits between 71,80%, and that persistent dampness accelerates rust inside the spring coils. Rust increases friction, reduces flexibility, and causes springs to break earlier than their rated lifespan. sometimes significantly earlier if the door hasn't been maintained.
The salt air near the bay, particularly for homes in Marina Faire or properties close to the Oyster Bay Regional Shoreline, compounds this further. If you haven't had your springs lubricated and inspected in the past year or two, they may already be closer to failure than you realize.
Before you call for a quote, it helps to know which type of spring your door uses.
Torsion springs mount horizontally above the door opening on a metal rod. They're the more common type in modern doors, and they're generally considered safer because when they break, they stay on the rod rather than flying loose. They also last longer.
Extension springs run along the horizontal tracks on either side of the door and work by stretching. They're typically found on older doors, including many of the 1940s and 1950s homes in Farrelly Pond District and Floresta Gardens. They're less expensive to replace but have a shorter lifespan and can be more hazardous when they fail.
If your home was built before 1980, there's a decent chance you have extension springs. and it may be worth discussing a torsion conversion with a technician. The upfront cost is higher (typically $400,$800 for a full conversion), but the safety improvement and longer service life often make it worthwhile.
Here's an honest breakdown. Nationally, spring replacement averages around $250, but Bay Area labor rates mean you should expect to pay somewhat more.
- Extension springs: roughly $100,$200 per spring, including labor - Torsion springs: roughly $150,$350 per spring, including labor - Full replacement for a single door (both springs): typically $300,$500 - Torsion spring conversion: $400,$800
One important note: if one spring breaks, replace both. Springs on the same door wear at the same rate, so if one has failed, the other is typically right behind it. Replacing both at the same time costs less in labor than two separate service calls, and it keeps your door properly balanced. Most reputable technicians will recommend this automatically. if they don't mention it, ask.
Be cautious of quotes significantly under $150 for a torsion spring job. That usually means economy-grade springs with a much shorter lifespan, or it means the quote doesn't include both springs.
You don't always get the loud bang warning. Sometimes springs give you advance notice if you know what to look for. Check out our full list of signs your garage door needs professional repair, but the spring-specific ones are:
- The door feels heavy when you try to lift it manually after disconnecting the opener - The door won't stay open at waist height. it slowly sinks back down - Visible gaps in the spring coils. torsion springs should be tightly wound; a gap means it's broken - Uneven movement. one side of the door rises faster than the other - Loud squeaking or grinding during operation, especially in cold or damp weather
If you're seeing rust on the coils along with any of the above, don't wait. A spring that's about to snap can damage your opener, bend the door tracks, or. in worst-case scenarios. cause injury.
We'll be direct about this: garage door spring replacement is one of the few home repairs where the DIY risk genuinely isn't worth it. Springs store an enormous amount of mechanical energy. A torsion spring under full tension, if mishandled during removal, can cause serious injury. Torsion springs in particular require specialized winding bars and precise technique. it's not a matter of watching a YouTube video and picking up the right tools.
Professional installation also ensures the springs are correctly sized for your specific door weight, properly tensioned, and balanced. An incorrectly tensioned spring puts strain on your opener motor and can shorten its life significantly. Visit our FAQ page for more on what a professional spring replacement involves.
A quality spring replacement should take about one to two hours. A good technician won't just swap the springs. they'll check your cables, rollers, and tracks for wear while they're there, test the door balance, and verify the auto-reverse safety function on your opener. If anything else looks marginal, they should tell you about it honestly rather than push unnecessary repairs.
Garage Door San Leandro serves San Leandro and surrounding East Bay communities including Castro Valley and Oakland. If your door is showing any of the warning signs above, schedule a service call before a weakened spring becomes a broken one.
The best garage door advice is always the least exciting: stay ahead of wear rather than reacting to failure. A spring inspection costs far less than an emergency call when your car is stuck in the garage on a workday morning.
Most springs are rated for 10,000,20,000 cycles, which translates to roughly 7,15 years for average household use. In San Leandro's humid, salty Bay Area climate, springs that aren't regularly lubricated often wear faster. sometimes failing in 5,7 years. Annual lubrication and inspection can meaningfully extend their life.
No. Operating a door with a broken spring puts excessive strain on the opener motor and cables, and can lead to the door dropping suddenly or the opener failing. Disconnect the opener and leave the door in place until a technician can assess it. Do not attempt to manually lift a door with a broken spring. it will be much heavier than expected.
Always replace both springs simultaneously. Springs on the same door experience the same wear and tear, so if one breaks, the other is close behind. Replacing both at once ensures balanced tension, prevents a second service call within months, and is more cost-effective since labor is the same either way.
