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 unexpected breakdowns, extends the life of your door and opener, and ensures safe operation. During a maintenance visit, our technicians will lubricate moving parts, check spring tension, test safety features, tighten hardware, and inspect all components for wear. If you use your garage door frequently (more than 4 times daily) or notice any unusual sounds or behavior, you may benefit from more frequent service. Annual maintenance can save you money in the long run by catching small issues before they become major repairs.

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

There are several warning signs that indicate your garage door springs may need replacement. The most obvious sign is if your door won't open at all or feels extremely heavy when lifting manually. You might also notice the door opening unevenly, leaving gaps on one side. Visible wear such as stretched, rusted, or gaps in the spring coils are clear indicators. Loud banging noises when operating the door or the door closing too quickly are safety concerns that require immediate attention. If your door opens a few inches then stops, or if you hear squeaking and grinding sounds, these are also signs of spring problems. Garage door springs typically last 10,000 cycles (about 7-10 years with normal use). Because springs are under high tension, we strongly recommend professional replacement rather than DIY attempts, as improper handling can cause serious injury.

How long does a garage door installation take?

A standard residential garage door installation typically takes between 4-6 hours to complete. This includes removing the old door (if applicable), installing the new door panels, setting up the track system, installing and adjusting springs, mounting the opener, programming remotes, and testing all safety features. The exact time can vary based on several factors: the type and size of door, whether we're replacing an existing door or installing in a new opening, the complexity of the opener system, and any additional features like windows or insulation. For new construction without an existing door, installation may take slightly longer. We always take the time to ensure everything is properly aligned, balanced, and functioning safely. After installation, our technicians will walk you through operation, maintenance tips, and answer any questions you have about your new garage door system.

Garage Door Photo Eye Safety in Mossyrock: How to Test and When to Replace

2026-07-20 7 min read A2Z Garage Doors

Your garage door's photo eye is a small sensor that stops the door from closing if something blocks its path. It's one of the cheapest safety features you have, and when it fails, the risk of serious injury jumps dramatically. Testing it takes 60 seconds and costs nothing. Skipping that test could cost thousands in medical bills or worse.

Most people don't think about their garage door until it stops working. By then, a broken photo eye may already be a problem. The good news? You can catch this before disaster strikes. See our guide on garage door spring types in mossyrock: torsion vs. extension explained.

What Does a Garage Door Photo Eye Actually Do?

The photo eye works with your garage door opener to provide auto-reverse protection. When the door closes, an infrared beam travels between two sensors (one on each side of the door frame, typically 4 to 6 inches above the ground). If anything interrupts that beam, the door immediately reverses direction.

This safety feature exists because garage doors weigh 300 to 400 pounds. A door closing on a child, pet, or parked car can cause crushing injuries or death. The photo eye is your primary defense. Read about boost your home security: garage door safety best practices.

Here's the catch: if the sensors are misaligned, dirty, or broken, they can't detect an obstruction. The door closes anyway.

How to Test Your Photo Eyes in Mossyrock

Testing takes less than a minute and requires no tools.

Step 1: Open the garage door fully.

Step 2: Look at the sensors on both sides of the door frame. Each should have a small light. If you see a steady light on one or both sensors, that's normal. If one or both lights are off or blinking, you have a problem.

Step 3: Place an object (a shoe, cardboard box, or broom handle) in the door's path. Close the door using your wall button or remote.

Step 4: Watch what happens. A working photo eye will stop the door and reverse it upward when the object blocks the beam. If the door keeps closing, your sensors have failed.

Step 5: Check for dirt or misalignment. Dust, spider webs, or debris can block the beam. Wipe the lens of each sensor with a soft, dry cloth. Repeat the test. If the door still doesn't reverse, the sensor itself is likely broken.

Common Reasons Photo Eyes Fail

Dirt and debris are the most common culprits. Mossyrock's Pacific Northwest weather brings moisture, pollen, and dust that coat sensor lenses. Clean sensors weekly during rainy months.

Misalignment happens when the door frame shifts slightly, bumping a sensor out of position. Even a quarter-inch of movement can block the beam. Look at both sensors. They should point directly at each other.

Broken wiring or a faulty sensor is the worst-case scenario. If cleaning and realigning don't work, the sensor needs replacement. A single sensor costs $50 to $150 in parts and labor. That's far cheaper than an emergency room visit.

The Cost of Ignoring a Broken Photo Eye

When a garage door closes without auto-reverse protection, child safety becomes a real concern. A door collapsing on a small child or pet can cause permanent injury or death. Beyond the human cost, there's the financial impact. Medical bills run into five or six figures. Liability lawsuits can exceed that.

A working photo eye costs less than a cup of coffee per year to maintain. Broken sensors cost thousands to fix after an accident.

We recommend testing your photo eyes every month. It takes 60 seconds and prevents disasters.

When to Replace Your Photo Eyes

Most photo eye sensors last 5 to 10 years if kept clean and properly aligned. If your garage door opener is more than 7 years old, expect the sensors to fail soon. We recommend replacing them before they break, especially if you have young children or pets.

Frequently Asked Questions

How often should I test my garage door photo eyes? Test them monthly, ideally before the rainy season hits. A quick 60-second check prevents injuries and catches misalignment early. Clean the lenses while you're at it.

Can I replace garage door photo eyes myself? Yes, if your opener is relatively new and the sensors are accessible. Most homeowners can swap sensors in 15 minutes using basic tools. However, if alignment is tricky, hire a professional to avoid future safety issues.

What does a blinking photo eye light mean? A blinking light usually indicates the sensors are misaligned. Check that both sensors point directly at each other. If they're aligned and the light still blinks, the sensor may be failing and needs replacement soon.

How much does a photo eye replacement cost in Mossyrock? A single sensor replacement typically runs $75 to $200 in parts and labor, depending on your opener model. A pair costs $150 to $300. Much cheaper than an emergency visit.

Do all garage doors have photo eyes? Most modern openers installed after 1990 have photo eyes as a safety requirement. Older doors may lack them. If yours doesn't have sensors, ask about upgrading during your next garage door opener maintenance.
