How much does garage door repair cost?

Garage door repair costs vary depending on the issue. Simple repairs like replacing a remote or adjusting sensors typically range from $75-$150. Spring replacement usually costs $150-$350 for a single spring or $250-$500 for a pair. Panel replacement can range from $200-$800 depending on the door type. At Garage Door Company Covina, we provide free estimates so you know exactly what to expect before any work begins. We also offer competitive pricing and stand behind our work with a lifetime warranty on all repairs.

How long does it take to replace a garage door?

A standard garage door replacement typically takes 3-5 hours from start to finish. This includes removing the old door, installing the new door and tracks, setting up the opener, and testing all safety features. More complex installations, such as custom doors, doors requiring structural modifications, or commercial installations, may take a full day or longer. Our experienced technicians work efficiently to minimize disruption to your schedule while ensuring quality installation.

Should I repair or replace my garage door?

The decision to repair or replace depends on several factors: the age of your door (doors over 15-20 years old often benefit from replacement), the extent of damage, energy efficiency needs, and your budget. Minor issues like broken springs, worn cables, or opener problems are usually worth repairing. However, if you're facing multiple repairs, significant panel damage, outdated safety features, or poor insulation, a new door may be more cost-effective long-term. We're happy to assess your door and provide honest recommendations based on your specific situation.

Garage Door Safety in Covina: Photo Eye & Auto-Reverse Explained

2026-09-24 5 min read

Your garage door is one of the heaviest moving objects in your home. If the safety features fail, it can crush a person or pet in seconds. Let's cut through the confusion about garage door safety and cover the two systems that actually protect your family.

How Photo Eyes Keep Your Door From Closing on Objects

A photo eye is a sensor mounted on each side of your garage door opening, about 6 inches off the ground. One sends an infrared beam across to the other. If anything blocks that beam while the door is closing, the opener reverses immediately.

This is not a luxury. It's a federal safety requirement since 1993. Every garage door opener sold in the U.S. must have photo eyes or an equivalent safety device.

Here's what I see go wrong in Covina homes: the sensors get dusty, misaligned, or someone covers them by accident. A single cobweb can trigger a false reversal. Worse, a blocked or misaligned photo eye might not work at all, and many homeowners never test it.

Test yours right now. Close your door and place a cardboard box in the path before it reaches the sensors. The door should reverse. If it doesn't, call us for a same-day inspection. A broken photo eye costs less to fix than dealing with an injury.

Auto-Reverse: Your Door's Second Line of Defense

Auto-reverse is the mechanical backup. When the door meets resistance while closing, a pressure-sensitive mechanism triggers the opener to reverse direction. It's literally a safety catch for when the photo eye fails.

The auto-reverse sensitivity can be adjusted. Too loose, and it won't catch a child's arm. Too tight, and the door reverses at the slightest vibration. Modern openers let technicians calibrate this precisely during installation.

If your garage door opener is older than 10 years, its auto-reverse may not meet current safety standards. Newer models have better sensors and faster reversal times. If you're considering an upgrade, understanding the garage door opener replacement options in Covina helps you choose one that actually protects your family.

Child Safety: Why You Can't Rely on Remote Controls Alone

A remote opener gives a child access to a 400-pound door. Kids don't understand the danger. They think it's a toy.

The best safeguard is a keypad with a changeable code mounted high on the wall, out of a small child's reach. Some families disable the remote entirely and use only the wall button or keypad. That puts you in control of who operates the door.

For families with young children, ask your technician about disabling the remote during service. It costs nothing and removes one risk factor entirely.

Monthly Safety Checks You Can Do Yourself

Test the auto-reverse by closing the door and placing your hand (not your head) in the path. The door should reverse immediately.

Check the photo eye lenses. Wipe them with a dry cloth. Look for dust, spider webs, or leaves blocking the beam.

Listen for grinding or squealing. If the door sounds rough, the springs or rollers may be failing, which affects how the auto-reverse performs. Springs last 7 to 9 years, not 10. When they're near the end, the door moves unevenly, and safety systems work harder.

Common Safety Mistakes Homeowners Make

Leaving the photo eye sensors covered or dirty is the most common mistake. The second is ignoring a door that reverses unexpectedly. That's not normal. It means the sensors are misaligned or the auto-reverse is too sensitive. Both are fixable, but only if you call a technician.

The third mistake is assuming an old garage door is "just fine." Older doors lack modern safety standards. If yours predates 2010, discuss an upgrade with a professional. Visit our garage door services page to learn what safety options are available.

When to Replace Safety Components

Photo eyes rarely fail, but they can. If one is cracked or the lens is damaged, replacement is urgent. If your auto-reverse isn't working, don't keep using the door. The risk is real.

Spring failure also affects safety. When a spring breaks, the door becomes harder to stop. The auto-reverse has to work twice as hard. If you suspect a spring issue, read our guide to garage door springs in Covina and schedule service immediately.

Frequently Asked Questions

What is a photo eye on a garage door? A photo eye is a safety sensor that shoots an infrared beam across the door opening. If anything interrupts the beam while the door closes, it signals the opener to stop and reverse. It's required on all modern garage doors to prevent injuries.

How often should I test my garage door auto-reverse? Test it monthly. Close the door and place an object in its path. It should reverse immediately. If it doesn't, call a technician right away. A faulty auto-reverse is a serious safety hazard.

Can dust on the photo eye sensors cause the door to malfunction? Yes. Even a thin layer of dust or a spider web can block the beam. Wipe the lenses with a dry cloth every month. If the door keeps reversing after cleaning, the sensors may be misaligned.

Is it safe to disable my garage door remote if I have young children? Yes, many families do this for child safety. Use a wall keypad with a code instead. Ask your technician to disable the remote during service, or do it yourself by removing batteries and storing them safely.

How much does a garage door safety inspection cost? Estimates are free. We'll test both the photo eye and auto-reverse, check spring condition, and advise on any repairs needed. Call (424) 581-0740 for a quote near you.
