How often should I have my garage door serviced?

We recommend having your garage door professionally serviced at least once a year. Regular maintenance extends the life of your door, prevents costly repairs, and ensures safe operation. During a maintenance visit, our technicians will lubricate moving parts, check spring tension, inspect cables and rollers, test the auto-reverse safety feature, and tighten all hardware. If you use your garage door more than 4 times per day, you may benefit from bi-annual maintenance.

How long does a garage door installation take?

A standard garage door installation typically takes 2-4 hours, depending on the complexity of the installation and the type of door. This includes removing the old door (if applicable), installing the new door, setting up the opener, programming remotes, and testing all safety features. For custom doors or doors requiring additional framing work, installation may take a full day. We'll provide you with a specific time estimate during your free consultation.

What are signs that my garage door springs need replacement?

Common signs that your garage door springs need replacement include: the door feels heavy when lifting manually, the door opens unevenly or crooked, visible gaps in the spring coils, squeaking or grinding noises, the door slams shut quickly, and the opener struggles to lift the door. Springs typically last 10,000-15,000 cycles (about 7-10 years for average use). Never attempt to replace springs yourself—they are under extreme tension and can cause serious injury. Our technicians are trained and equipped to safely handle spring replacement.

Your garage door photo eye is a small sensor that stops a 400-pound door from crushing a child, pet, or your hand in less than a second. Most people don't think about their garage door until it stops working, but by then, the safety systems that protect your family may already be failing. If your photo eye isn't functioning, your door is a hazard waiting to happen.

What Is a Garage Door Photo Eye?

A photo eye is an infrared sensor system installed on both sides of your garage door opening, about 6 inches above the ground. One sensor sends a beam across the opening; the other receives it. When something blocks that beam, the door automatically reverses direction. This is your garage door's auto-reverse safety feature, required by federal law since 1993.

Without working photo eyes, your garage door opener has no way to detect an obstruction. A child reaching under a closing door. A pet in the path. A tricycle left in the driveway. None of these trigger a stop anymore. The door keeps closing. The weight crushes whatever is underneath.

I've seen families in San Marcos who waited too long to address photo eye problems. A blocked door sensor here, a misaligned beam there. Small issues become catastrophic when you're not paying attention. Don't be that household.

How Photo Eyes Fail

Photo eye failures happen for three main reasons. First, dirt and dust accumulate on the lens, blocking the infrared beam. San Marcos sun and heat accelerate this buildup. Second, the sensors drift out of alignment, usually from vibration or accidental bumping during door operation. Third, the wiring gets damaged or the sensor itself fails electrically.

You might notice your door reversing randomly, refusing to close all the way, or stopping mid-cycle. These are warning signs. Test your photo eyes monthly by placing an object in the door's path as it closes. The door should reverse immediately. If it doesn't, call for service right away.

Why This Matters for Child Safety

Child safety is non-negotiable. A garage door can exert 400 pounds of force. Pediatric injuries from garage doors include crushed fingers, broken bones, and worse. Your photo eye is the only thing standing between a curious toddler and serious harm.

If you have young children or regularly have kids visiting your home, inspect your photo eye system every month. Look for visible dirt on the lenses. Check that both sensors are properly aligned and mounted firmly. Test the auto-reverse function yourself. Don't rely on it "probably working."

Many families assume their door is safe because it's new. Age doesn't matter. A misaligned sensor on a brand-new door is just as dangerous as a failing sensor on an old one. What matters is whether the system actually functions right now, today.

How to Tell If Your Photo Eyes Are Failing

Check for these specific warning signs. Your door closes smoothly sometimes but reverses other times without anything blocking it. The door won't close unless you hold the wall button continuously. You see visible dirt, cobwebs, or discoloration on either sensor lens. The sensors appear loose or tilted at odd angles.

Test the alignment by shining a flashlight at one sensor from the opposite side. If you can't see the light reflection, the beam path is broken. That means the door is operating without protection.

If any of these describe your situation, don't delay. A free safety estimate costs nothing and takes minutes. Our technicians can diagnose the problem, clean or realign the sensors, and restore your auto-reverse function before you leave. Get a same-day estimate by calling 760-938-9310 or scheduling online.

Prevention and Maintenance

Photo eye problems are often preventable. Keep the area around your garage door clear of dirt, spider webs, and debris. Wipe the sensor lenses clean with a soft cloth quarterly, especially during San Marcos' dusty seasons. Avoid bumping the sensors when moving items in or out of the garage.

If you've had your garage door longer than seven years, the original photo eyes may be nearing end-of-life. Consider replacement as part of your maintenance routine. Modern sensors are more reliable and more sensitive to obstructions.

When to Call a Professional

Photo eye repair isn't a DIY task. Misaligned sensors might look fine but fail to detect a real obstruction. Wiring issues require electrical expertise. If your photo eye isn't working or you're unsure, contact a licensed technician.

Frequently Asked Questions

Q: How often should I test my garage door photo eyes? A: Test monthly by placing an object in the closing door's path. The door should reverse within one second. If it doesn't, stop using the door and call for service immediately. Weekly checks are even better if you have small children in the home.

Q: Can I clean the photo eye lenses myself? A: Yes. Use a soft, dry cloth to gently wipe each lens monthly. Never use harsh chemicals or abrasive materials. If cleaning doesn't fix the problem, the sensors may be misaligned or failing electrically. Have a professional inspect them.

Q: What does it mean if my door reverses on its own? A: Random reversals usually indicate a dirty lens, misalignment, or electrical interference. Sometimes insects or debris trigger the beam momentarily. Clean the lenses first. If reversals continue, the sensors may need realignment or replacement.

Q: Are photo eyes required on all garage doors? A: Federal law requires auto-reverse safety features on all residential garage door openers manufactured after 1993. If your door doesn't have photo eyes or they're not working, your opener is not compliant and poses a serious safety risk.

Q: How much does photo eye repair cost? A: Cleaning or realigning photo eyes typically costs $75 to $150. Replacing both sensors usually runs $150 to $300. Get a free estimate by calling 760-938-9310. Most repairs can be completed same-day at no additional cost.
