For true emergencies—like a door stuck open or a security concern—we offer 24/7 emergency service with priority dispatch.

What are signs that my garage door needs repair?

Common signs include: unusual noises (grinding, squeaking, or banging), the door moving unevenly or jerking, the door not fully opening or closing, visible damage to springs or cables, the door reversing unexpectedly, or the opener not responding. If you notice any of these issues, it's best to call a professional before the problem worsens.

Is it safe to repair a garage door spring myself?

No—garage door spring repair is extremely dangerous and should only be done by trained professionals. Springs are under tremendous tension (enough to lift a 200+ pound door) and can cause serious injury or death if they snap or are handled incorrectly. We strongly advise against any DIY spring repair. Call a licensed technician for safe, proper repair.

How often should I have my garage door serviced?

We recommend professional maintenance once a year. During a maintenance visit, we lubricate all moving parts, check spring tension, inspect cables and rollers, test safety features, and make minor adjustments. Regular maintenance extends your door's lifespan, prevents costly repairs, and keeps your door operating safely and quietly.

Do you provide warranties on repairs?

Yes, all our repairs come with warranties. Parts are covered by manufacturer warranties (typically 1-5 years depending on the component). Our labor is warranted for 90 days. For new door installations, we offer comprehensive warranties covering both the door and installation. Ask your technician for specific warranty details on your repair.

Our technicians are factory-trained on multiple brands and carry common parts for all of them. If you have an older or less common brand, we can usually source parts within 24-48 hours.

How do I know if I need a new garage door or just repairs?

Consider replacement if: your door is over 15-20 years old, requires frequent repairs, has significant rust or structural damage, lacks modern safety features, or if repair costs approach 50% of a new door's price. Our technicians provide honest assessments—we'll recommend repair when it makes sense and explain when replacement is the better investment.

Garage Door Photo Eye Safety in Commerce, CA: What Homeowners Miss

2026-07-26 7 min read

Your garage door's photo eye is a small sensor that stops your door from closing if something blocks its path. It's one of the cheapest safety devices on your door, yet we see broken or misaligned photo eyes in homes across Commerce every single week. A faulty photo eye puts your family at real risk of crushing injuries. The good news: this is often a problem you can spot yourself before it becomes dangerous.

What a Photo Eye Actually Does

The photo eye works like a invisible trip wire. Two sensors face each other across your garage door opening, about six inches from the ground. When the door closes, it sends an invisible infrared beam between them. If anything blocks that beam, the door stops and reverses. It's your door's main defense against crushing injuries to children, pets, or even your own legs if you're retrieving something forgotten in the garage.

Federal safety standards require all residential garage doors built after 1993 to have photo eyes. If your door is older, you can add them as an upgrade. The cost is modest compared to the protection they provide.

Common Photo Eye Problems We See in Commerce Homes

Misalignment is the biggest culprit. Over time, vibration from the door opening and closing nudges the sensors out of position. Even a quarter-inch shift can break the beam. Dirt, spider webs, and dust collect on the lens. Moisture and salt air in our Commerce climate can corrode the wiring. Sometimes a child or pet accidentally bumps a sensor during play. A garage door that won't close on its own (but will close if you hold the button) usually points to a photo eye issue.

You can test this yourself. Close the door using the wall button. Once it's halfway down, wave your hand through the sensor area. The door should stop and reverse. If it doesn't, your photo eyes need attention.

How to Inspect Your Photo Eyes Right Now

Walk to your garage door sensors. They're typically mounted on each side of the opening, near the bottom. Look for visible damage, loose wiring, or obvious misalignment. Clean the lenses gently with a soft, dry cloth. Debris is often the quickest fix. Check that both sensors point directly at each other. If one is angled away, that's your problem.

Many photo eyes have a small light indicator. If it's off, the sensor isn't receiving power. Check the outlet and any connections. If the light is on but your door still won't reverse when blocked, the beam itself may be broken or the door's control board may not recognize the signal.

This is when you should call a professional. Misalignment that requires physical adjustment, wiring issues, or sensor replacement are jobs best left to someone trained on your specific door model. A garage door repair appointment in Commerce can diagnose the exact problem and prevent a safety hazard.

The Auto-Reverse Feature and Why It Matters

Your garage door opener also has a mechanical auto-reverse, separate from the photo eye. If something blocks the door while closing, the opener detects resistance and reverses. However, this feature degrades over time and can fail. The photo eye is your backup. Together, they're what protect your child from a crushing injury if they duck under a closing door.

We've written about five major garage door safety hazards in Commerce that homeowners overlook. Photo eyes are just one piece of the puzzle, but they're one you can maintain yourself with a little attention.

Cost to Repair or Replace Photo Eyes

A single photo eye sensor costs between $25 and $80. Labor to realign or replace them typically runs $100 to $250. This is far cheaper than an ER visit or permanent injury. Many homeowners put off this repair thinking it's expensive. It's not. The real cost comes when you ignore the warning sign that your door won't close properly.

If you're unsure whether your photo eyes are working, schedule a free quote and we'll inspect them as part of a safety check. Same-day estimates are available in most cases.

Keeping Your Photo Eyes Safe Year-Round

Check your sensors every few months. Wipe the lenses clean. Make sure nothing is blocking the beam path. Keep boxes and tools away from the sensor area. Teach children not to play with the garage door or touch the sensors. If you notice your door behaving oddly, test the photo eyes first before assuming the worst.

Garage door safety doesn't require expensive upgrades or constant maintenance. It requires awareness. A broken photo eye is a red flag you shouldn't ignore. Fix it now, and you've eliminated one of the biggest crushing-injury risks in your home.

Your family's safety is worth a phone call. Reach us at (213) 724-1341 or contact us online to schedule your photo eye inspection today.
