How often should I have my garage door serviced?

We recommend having your garage door professionally serviced at least once a year. Regular maintenance helps prevent costly repairs, extends the life of your door and opener, and ensures safe operation. During a maintenance visit, our technicians at Garage Door Laguna Woods will inspect all components, lubricate moving parts, check safety features, and make any necessary adjustments. For commercial doors or doors with heavy use, semi-annual maintenance may be advisable. Between professional visits, homeowners should visually inspect their door monthly and listen for unusual sounds during operation. If you notice any issues like slow movement, loud noises, or uneven operation, contact us right away to prevent more serious problems.

What are the signs that my garage door springs need replacement?

Several warning signs indicate your garage door springs may need replacement. The most obvious is when the door feels heavy or struggles to open, as this means the springs are no longer providing adequate counterbalance. You may also notice the door opening unevenly, with one side higher than the other. Visible wear such as gaps in the spring coils, rust, or stretched-out springs are clear indicators. A loud bang from the garage often signals a spring has broken. Other signs include the door closing too quickly, the opener straining to lift the door, or the door not staying open when released. Garage door springs are under extreme tension and should only be replaced by trained professionals like our team at Garage Door Laguna Woods. Attempting DIY spring replacement can result in serious injury. If you notice any of these signs, contact us immediately for a safe inspection and replacement.

How long does a garage door installation typically take?

A standard residential garage door installation typically takes between 3 to 6 hours, depending on several factors. A straightforward replacement of a single door with an existing opener usually falls on the shorter end of that range. Factors that can extend the installation time include replacing the opener along with the door, installing a new door where none existed, custom doors requiring precise fitting, adding windows or decorative hardware, upgrading insulation, or addressing any existing structural issues. At Garage Door Laguna Woods, we always perform a thorough site inspection before installation to provide an accurate time estimate. Our experienced installers work efficiently while maintaining our high-quality standards. Most installations are completed in one day, allowing you to use your new garage door by that evening. We also take time at the end of every installation to test all safety features and explain the operation and maintenance of your new door.

Garage Door Photo Eye Safety in Laguna Woods: Why It Fails and How to Fix It

2026-08-01 7 min read A2Z Garage Doors

A customer called last Tuesday with a question that made my stomach drop: their garage door hadn't reversed on its own in weeks. They had a toddler in the home and didn't realize the photo eye (the safety sensor near the bottom of the door frame) was no longer working. Photo eye failure is one of the most dangerous garage door problems because most homeowners never notice until a close call happens. This invisible safety system stops your door from crushing a child, pet, or vehicle. When it fails silently, you lose your last line of defense.

What Is a Photo Eye and Why Does It Matter?

Your garage door photo eye is a small infrared sensor mounted on both sides of the opening, about 4 to 6 inches above the ground. One side sends a beam; the other receives it. If anything blocks that beam while the door is closing, the auto-reverse mechanism kicks in and the door stops and reverses upward. It's the law in California, and it's saved countless lives since the 1980s.

Without a working photo eye, your door will close on anything in its path. A child's head. A bicycle. A pet. The force of a garage door can exceed 400 pounds, and it takes only a fraction of a second to cause permanent injury or death.

Why Photo Eyes Fail in Laguna Woods

The coastal climate here works against safety sensors. Salt air corrodes the lens and electronic components. Spider webs and dirt accumulate on the emitter or receiver lens, blocking the beam. I've seen photo eyes fail because of misalignment from a single hard closing or a bump from a vehicle.

Weather isn't the only culprit. Homeowners accidentally knock photo eyes out of position during clutter cleanup. Garage door openers malfunction and stop sending the signal. Wiring gets chewed by rodents. Sometimes the photo eye itself simply ages out after 10 to 15 years of operation.

How to Check If Your Photo Eye Is Working

Walk to your garage door and look at the small sensors on both sides of the opening near the floor. They usually have a light indicator (red, green, or amber depending on the brand). Close the door and watch for the light. If it goes out or changes color, the beam is active.

Next, place an object in the door's path and press the close button. The door should stop or reverse immediately. If it doesn't, your photo eye is not communicating with the opener.

You can also wave your hand across the sensor area while the door is closing. A working photo eye will stop the door. If nothing happens, you have a problem that requires professional attention.

Photo Eye Repair vs. Replacement Cost

A photo eye cleaning or realignment runs 75 to 150 dollars and takes 30 minutes. Replacement of both sensors costs 150 to 300 dollars depending on the opener model. If the wiring is damaged or the opener itself is faulty, that estimate will climb. The good news: a same-day repair is usually possible for most homes in Laguna Woods.

Compare this to the cost of a child injury lawsuit or an emergency room visit. Safety is not the place to save money. If you're unsure whether your photo eye is working, a quick professional inspection provides peace of mind and catches problems before they become tragedies.

For a full breakdown of what you might expect to pay, our guide on garage door safety in Laguna Woods covers what every family needs to know before a failure occurs.

Testing Child Safety Features Beyond the Photo Eye

Photo eyes are only one part of your garage door safety system. The auto-reverse mechanism (which the photo eye triggers) must be tested monthly. Close the door and gently press up against the bottom with your hand. The door should reverse immediately. If it requires significant force or doesn't reverse, the mechanism needs adjustment.

Older openers may not have adequate safety features at all. If your garage door opener is more than 20 years old, it likely lacks modern auto-reverse technology. Upgrading to a current model improves child safety dramatically. Learn about smart garage door technology benefits in Laguna Woods and how newer openers add remote monitoring so you can verify door status from your phone.

When to Call a Professional

Never attempt to repair photo eye wiring or realign sensors yourself unless you have electrical experience. Misdiagnosis wastes time and leaves the door unsafe. Professional technicians at Garage Door Laguna Woods use diagnostic tools to confirm the problem and fix it correctly the first time.

If your photo eye has failed, contact us today for a same-day inspection and estimate. We'll test every safety component, explain what needs fixing, and get your door back to safe operation. Your family's protection is worth the call.

Frequently Asked Questions

How often should I test my photo eye? Test your photo eye monthly by closing the door and checking for the light indicator. Wave your hand across the sensors to confirm the beam stops the door. A quick 30-second check prevents serious injuries.

Can a dirty lens cause a photo eye to fail? Yes. Salt spray, dust, and spider webs block the infrared beam. Gently wipe the lenses with a soft, dry cloth. If cleaning doesn't restore function, the sensor may be damaged and needs replacement.

What's the difference between a photo eye and an auto-reverse? The photo eye is the sensor that detects obstacles. The auto-reverse is the mechanism that reverses the door when triggered. Both must work together for child safety.

Do all garage door openers have photo eyes? Federal law requires all garage doors manufactured after 1993 to have photo eyes or equivalent safety sensors. If yours is missing or broken, upgrade or repair immediately.

How long do photo eyes last? Most photo eyes function 10 to 15 years before age or weather damage requires replacement. Coastal homes like those in Laguna Woods may experience faster corrosion.
