Garage Door Repair in Union City: Why Your Door Won't Open
2026-05-16 7 min read
In our years serving Union City, we've seen this problem again and again: a garage door that won't open, and the homeowner has no idea why. Nine times out of ten, it's a broken spring. The good news? You don't need to guess. This guide walks you through what's happening, why it matters, and when to call a professional.
Why Your Garage Door Won't Open
A garage door that's stuck or won't budge almost always points to one culprit: a broken torsion spring. These springs carry roughly 200 pounds of tension. When one snaps, your opener motor can't lift the door anymore. That's not a safety issue yet, but it's also not something you should ignore. See our guide on essential garage door maintenance tips.
Springs last between 7 and 9 years under normal use. If your door is older than that and suddenly won't open, a spring failure is highly likely. Unlike a stuck door from leaves or debris, a broken spring requires professional repair. Attempting a DIY fix on a spring under tension can cause serious injury.
How to Troubleshoot Before You Call
Start simple. If your garage door won't open, check whether the opener is getting power. Listen for a clicking sound when you press the button. No click? Check your breaker and outlet. A power issue is cheap to fix yourself. Read about garage door maintenance in union city: what homeowners miss.
Next, inspect the door visually from inside the garage. Look at the spring above the door. A broken spring will hang slack, often with a visible gap where it snapped. If the spring looks intact, the problem might be a broken cable, misaligned track, or a failed opener motor. All of these require professional diagnosis.
For a stuck door that might open partway, try the emergency release on your opener. Pull the red cord to disconnect the motor, then manually push the door up. If it's extremely heavy or won't budge, stop immediately. That confirms a spring is broken.

The Cost of Garage Door Repair
A broken spring repair typically runs between $250 and $400 in Union City and the broader Bay Area. That price includes the spring itself, labor, and a safety inspection. We always provide a free estimate before starting work, so you know exactly what to expect. No hidden fees, no surprises.
If both springs are broken, or if the door has other damage, the cost increases. Some homeowners see this as an opportunity to upgrade to a newer, more efficient door. If your door is over 15 years old, it might be worth exploring options. Check out our guide to upgrading older homes to see whether replacement makes sense for your situation.
Same-day repair is usually possible if you call before 2 p.m. on a weekday. We keep spring stock on hand specifically to handle emergency calls. When your garage door is broken, we know you need it fixed fast.
When to Call a Professional
If you've confirmed a broken spring, don't delay. A non-working garage door is a security risk and a hassle for daily life. More importantly, continuing to use the opener with a broken spring will burn out the motor faster, adding another $400 to $600 to your final bill.

What Happens During a Professional Repair
When we arrive, we inspect the entire door assembly, not just the broken part. A spring failure sometimes signals that the door is off balance or that other components are wearing unevenly. We'll replace the broken spring or springs, check cable tension, lubricate moving parts, and test the door for smooth, safe operation. The whole job usually takes under an hour.
We also never sell you parts you don't need. Our honest pricing approach means you pay for what's actually broken, plus labor. Many repair shops bundle unnecessary work into their estimates. That's not how we operate.
Preventing Future Breakdowns
Regular maintenance extends spring life and catches wear patterns early. Our essential maintenance tips cover lubrication, balance testing, and visual inspections that take 15 minutes a few times per year.
If your door is approaching the 7 to 9 year mark for spring life, we recommend a preventive inspection. Replacing one spring before it breaks is far cheaper than emergency same-day repair. Visit our services page to learn more about our repair and maintenance options.

Frequently Asked Questions
How do I know if my spring is broken? A broken spring hangs slack or shows a visible gap above the door. The door will be extremely heavy when you try to lift it manually. You may also hear a loud bang when the spring snaps, which can occur during normal operation.
Can I use my garage door opener if the spring is broken? No. Using the opener with a broken spring will damage the motor and gearbox, costing $400 to $600 more to replace. Stop using the opener immediately and call for repair.
How long does a spring replacement take? Most spring replacements are completed within 30 to 60 minutes, including a full safety inspection and testing. We offer same-day service for calls before 2 p.m. on weekdays.
Why do garage door springs fail? Springs wear out from repeated cycles of opening and closing. A typical spring handles 10,000 to 20,000 cycles before failure. Lack of lubrication, rust, and hard water exposure accelerate wear in the Bay Area.
What's the difference between a torsion spring and extension springs? Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch. Torsion springs are more common in residential garages and last longer than extension springs.
