When your garage door won't open or stays stuck, the cause is usually one of five common culprits. We've handled thousands of repairs across Duarte and the San Gabriel Valley, and most problems are fixable without a full replacement. Let's cut through the confusion and show you what's actually broken.
Your garage door is a system. Springs, cables, rollers, tracks, and the opener all work together. When one fails, the whole door stops functioning.
Broken springs are the number one reason doors get stuck. These metal coils support the weight of your door (usually 300 to 400 pounds). Springs last 7 to 9 years, not longer. When they snap, the door becomes nearly impossible to open manually, and the opener can't lift it. This is dangerous. Never try to force a broken spring yourself.
Damaged tracks happen when something hits the door or the frame shifts over time. A bent track makes the rollers jam. The door sounds like it's grinding and moves unevenly. This is one of the easier repairs we do, and the cost is lower than spring replacement.
Cable problems mirror spring issues. Cables run over pulleys and support the door's weight alongside springs. If a cable snaps, you'll hear it and feel slack in the system. The door may tilt or hang crooked.
Opener motor failure means the door won't respond to your remote or wall button. The opener itself may hum but not lift. Power issues, worn gears, or burned-out motors all fall here. Sometimes it's just a blown capacitor (a small, cheap fix). Other times you need a new opener.
Misaligned sensors are increasingly common with older systems. If your door reverses halfway down or won't close all the way, the safety sensors might be dirty or knocked out of alignment. This is a troubleshooting task, not a replacement.
Start simple. Check if power is reaching the opener. Is the outlet working? Try plugging a lamp in. If the outlet is dead, reset the breaker or GFCI. If power is on and the opener hums but the door doesn't move, the motor or internal gears are likely failing.
Next, look at the door itself. Does it move at all when you press the button? If it's completely stuck and won't budge, a spring is probably broken. Don't force it. A broken spring under tension is hazardous.
For doors that move slowly or make noise, inspect the tracks and rollers. Dirt, rust, and debris accumulate over years. If you see buildup, clean it out with a brush. Light lubricant (not WD-40; use a garage door specific spray) can help. But if the track is bent, cleaning won't fix it.
If the door closes and then immediately reverses, the safety sensors at the bottom of each side need attention. Look for dirt on the lens. Wipe them clean with a soft cloth. Make sure neither sensor is blocked by boxes or debris. Misaligned sensors can be reset by loosening their brackets slightly and pointing them at each other.

Cleaning tracks and sensors? Safe to do yourself. Lubricating rollers and hinges? Fine. Adjusting sensor alignment? Yes, go ahead.
Do NOT attempt to replace springs or cables. This is the most common mistake homeowners make, and it causes injury. Springs are under extreme tension. Cables snap. Professional tools and safety equipment are required.
Do NOT ignore a broken spring or cable hoping it fixes itself. The door will only get harder to operate, and you risk damaging the opener or the door panels. A small repair today costs far less than a full replacement later.

A broken garage door isn't just inconvenient. It's a security risk. An open or stuck door leaves your home and car exposed. It also puts stress on other components. An opener working overtime to lift a door with broken springs will burn out faster. That $150 spring repair becomes a $400 opener replacement.

How do I know if my garage door spring is broken? A broken spring usually makes a loud snap or pop sound. After that, the door either won't open at all or feels extremely heavy when you try to lift it manually. The door may also hang crooked or tilt to one side. Never force a stuck door; call a professional immediately.
Can I fix a bent garage door track myself? Small dents can sometimes be tapped out with a rubber mallet, but bent tracks usually require removal and replacement. If the bend is severe, DIY attempts often make it worse. A pro can straighten or replace the track in under an hour for a reasonable cost.
Why does my garage door reverse when closing? Misaligned safety sensors are the most common cause. Look at the sensors at the bottom corners of the door frame. Wipe the lenses clean and make sure nothing blocks them. If they're still not aligned, they may need adjustment by a technician.
How much does garage door repair typically cost in Duarte? Repair costs range from $150 for sensor adjustments to $500 for spring or cable replacement. Opener repairs fall between $200 and $400 depending on the issue. Read our full pricing guide for detailed breakdowns.
Should I replace my garage door or repair it? If the door is under 15 years old and only one or two components are broken, repair is almost always the right choice. Replacement makes sense if the door is damaged beyond repair, very old, or repeatedly breaking down. We can help you decide during a free inspection.
