Most people don't think about their garage door until something goes wrong. Then they hear that unmistakable sound: a loud crack or snap. Nine times out of ten, that's a broken spring. In San Leandro, we see this happen weekly. The good news? You don't need to panic, and you absolutely don't need to replace the entire door.
Your garage door weighs 300 to 500 pounds. It doesn't stay open or close smoothly because of magic. Two springs (or sometimes one, depending on your setup) do all the heavy lifting. These are either torsion springs mounted above the door or extension springs running along the sides.
Torsion springs are the most common in residential homes. They're engineered to open and close your door roughly 10,000 times before wearing out. That sounds like a lot, but if you use your garage door twice daily, you're looking at 7 to 9 years of life. Extension springs last about the same timeframe and work by stretching and contracting to counterbalance the door's weight.
Neither type lasts forever. Metal fatigues. Temperature swings in the Bay Area, from cool mornings to warm afternoons, cause expansion and contraction. Eventually, the spring snaps.
A snapped spring usually announces itself loudly. You'll hear a bang or crack when operating the door. After that, the door either won't open at all or feels heavy and sluggish.
Some warning signs come earlier. If your door closes faster than normal or opens slowly, the springs are weakening. You might notice the door hanging slightly off balance. These are cries for help before total failure.
Never try to force a stuck door with a snapped spring. You risk serious injury or damage to the opener. Instead, call a professional. We can handle same-day service in most cases across San Leandro and the surrounding East Bay.
The cost question matters, and homeowners deserve straight answers. A single spring replacement typically runs $150 to $300, including labor and the part itself. If both springs have failed (which happens), expect $300 to $500 total.
That estimate assumes standard torsion or extension springs. Heavy-duty or commercial-grade springs cost more. A full door replacement, by contrast, runs $800 to $3,500 depending on insulation, material, and features.
Here's the technician's perspective: if one spring snaps, the other is usually close behind. We often recommend replacing both at the same time. Yes, it costs a bit more upfront, but it saves you from a second service call in six months.

I've been doing this work for 15 years. The number one mistake homeowners make is trying to replace springs themselves. Springs are under extreme tension. If you slip, a spring can whip and cause deep cuts, broken bones, or worse. The tools required are specialized. A spring hook, a winding bar, and proper safety equipment aren't cheap, and they're useless after one job.
Leave this to the pros. It takes us 45 minutes to an hour. It could take you a weekend and a trip to the emergency room. The math doesn't work in your favor.
Our team at Garage Door San Leandro handles all spring replacements with insurance and warranty backing. We test everything before we leave your driveway.
The best way to extend spring life is routine maintenance. Regular lubrication, balance checks, and opener testing catch worn springs early. When you catch them early, you replace them on your schedule, not on an emergency basis at night or on a weekend.
We recommend a tune-up once a year. Read more about why routine garage door maintenance matters in San Leandro and what a professional inspection includes.

How do I know if I have one spring or two? Most residential doors use two springs. Open your garage door manually (in case the opener is stuck) and look above the door. You'll see either two torsion springs side by side or two extension springs along the tracks. Single-spring setups are rare and usually found on lighter doors.
Can I still use my garage door if one spring is broken? Technically, yes, but don't. A broken spring throws the door out of balance, straining the opener and tracks. You risk further damage. Manual operation is extremely difficult and unsafe. Call for service instead.
Are spring replacements covered by warranty? Springs have their own lifespan, so most home warranties don't cover them. However, our service includes a one-year warranty on parts and labor. Always ask what's covered before work begins.
What's the difference between torsion and extension springs? Torsion springs twist to lift the door and mount horizontally above it. Extension springs stretch and contract, running vertically along the tracks. Torsion springs are more durable and common in newer homes. Both need professional replacement.
How much does spring replacement cost near me? In San Leandro, expect $150 to $300 per spring, including labor and materials. Most homes need two replaced at once, bringing the total to $300 to $500. Contact us at (415) 754-9790 for a firm estimate based on your specific door and springs.
