If you've ever heard a sudden loud bang coming from your garage in the middle of the night, there's a good chance a torsion spring just gave out. It's one of the most jarring moments a Milpitas homeowner can experience. and unfortunately, it's also one of the most common garage door repair calls we get. The good news is that with a little knowledge, you can often see the warning signs before a full failure happens.
Milpitas has a Mediterranean climate. mild, wet winters and warm, dry summers. That seasonal swing between damp, cool conditions from November through March and hot, dry stretches in July and August puts real stress on metal components over time. Springs expand and contract with temperature changes, and that repeated movement adds up.
Most standard garage door springs are rated for about 10,000 cycles. roughly one full open-and-close counts as one cycle. For the average household using the garage door four or five times a day, that works out to somewhere between 7 and 10 years before replacement is due. If your home is in a busier neighborhood like Curtner Estates or Parktown where families are constantly coming and going, those cycles burn through faster than you'd expect.
And if you have one of the older two-story stucco tract homes that make up a large share of Milpitas's housing stock. many now 40 or 50 years old. there's a solid chance the springs have either already been replaced once or are overdue.
Don't wait for the loud bang. These are the real-world warning signs to watch for:
Spring systems do the heavy lifting so your opener motor doesn't have to. When springs start losing tension, the door starts feeling heavier. and your opener strains to compensate. If you disconnect the opener and try to lift the door manually, it should rise smoothly and stay in place halfway up. If it drops or feels like dead weight, your springs are losing tension.
A door that rises or closes in a lurching, uneven motion is a red flag. This often means one spring has failed while the other is still working, creating an imbalance that stresses the cables, tracks, and opener simultaneously. Left unchecked, what starts as a spring problem can cascade into a much more expensive repair. check our guide on warning signs for a full breakdown of what to watch for.
Take a look at the torsion spring mounted horizontally above your garage door. If you can see a clear gap or separation in the coil. like a section has stretched apart. the spring has broken. At that point, the door should not be operated until it's replaced.
Some noise is normal, but new grinding or squeaking coming from the spring area (not just the rollers) suggests the metal is under strain or starting to dry out. A good squirt of garage door lubricant. not WD-40, which actually strips lubrication over time. on the spring coils every few months can extend their life noticeably. Our seasonal maintenance guide covers exactly what to lubricate and when.
This is one of the most common questions we hear. The practical answer: replace both at the same time, even if only one has visibly failed. Springs on the same door age at the same rate, so if one snaps, the other is likely close behind. Replacing both in a single visit saves you a second service call charge and keeps the door balanced.
Spring replacement in California typically runs between $200 and $500 depending on the spring type, door size, and how many springs need replacing. Torsion spring replacements. the type found on most modern sectional doors. tend to sit toward the higher end of that range because they require specialized tools and training. Extension springs, common on older tilt-up style doors still found in some Milpitas neighborhoods near San Jose, are generally less expensive to replace.
One thing worth knowing: this is not a DIY project. Garage door springs are under enormous tension. they handle loads of 150 to 400 pounds. and an improperly handled spring can cause serious injury. The only safe approach is to call a professional.

- Lubricate springs every 3,6 months using a dedicated garage door lubricant - Test door balance twice a year by disconnecting the opener and manually lifting the door halfway - Avoid slamming the door. every forceful close adds unnecessary wear - Replace both springs together to maintain balance and avoid repeat service calls
Q: How do I know if it's the spring that's broken and not the opener? A: Disconnect the opener by pulling the red emergency cord, then try to lift the door manually. If it's extremely heavy or won't stay up on its own, the spring is the likely culprit. If the door lifts easily by hand but the opener still won't run, the problem is with the motor or electronics.
Q: Is it safe to use my garage door with a broken spring? A: No. Operating a door with a broken spring puts extreme strain on the opener motor and cables, and the door could drop unexpectedly. Stop using it and call for repair as soon as possible.
Q: How long does a spring replacement take? A: A professional technician can typically complete a standard torsion spring replacement in one to two hours, often in a single same-day visit.
