In our 15 years serving Lake Oswego and the surrounding Portland metro, we've seen this problem again and again: homeowners assume their garage door is safe because it opens and closes. That assumption costs families. A door that moves smoothly can still pose serious risks to children, pets, and parked cars. This post walks you through the safety checks you can do yourself, right now, before something goes wrong.
Your garage door weighs 300 to 500 pounds and moves on springs under extreme tension. It's one of the heaviest moving objects in your home. If the safety systems fail, that door becomes a hazard. A child's hand, a pet, or a car parked underneath can be injured or worse in seconds. Regular inspection catches problems early, when they're cheap to fix, not after an accident.
The good news: most critical safety checks take 10 minutes. You don't need special tools. You just need to know what to look for.
Your garage door opener has two small sensors called photo eyes. They sit on opposite sides of the door frame, about 6 inches above the ground. When something blocks the beam between them, the door should reverse immediately. If the photo eye fails, the door won't stop even if a child runs underneath.
Clean both sensors first. Use a soft cloth. Dust and spider webs block the beam. Then close the door. As it's closing, wave your hand across the sensors. The door should stop and reverse. If it doesn't, your photo eye is broken. This is a same-day repair we handle all the time in Lake Oswego. Don't wait on this one.

The auto-reverse is your door's last defense. Place a 2x4 block of wood flat on the ground where the door closes. Activate the door. It should touch the wood, reverse immediately, and go back up. If it keeps pushing down, the auto-reverse sensor is out of adjustment or the door has a mechanical problem. This is dangerous. Don't use the door until it's fixed.
If the auto-reverse fails on one cycle, test it twice more. Sometimes a misalignment causes a one-time glitch. Consistent failure means you need a technician. We can often fix auto-reverse sensors in one visit for a fraction of what replacement costs.
Walk around your door. Look at the springs above the frame. If you see a gap in the spring, or if one spring looks visibly stretched while the other looks normal, one spring is broken. Do not operate the door. A broken spring can snap suddenly. It's under thousands of pounds of tension.
Also check the bolts and brackets holding the track to your garage wall. Are any loose? Are any brackets bent? Over time, the weight of the door causes fasteners to loosen. Tighten bolts by hand if you can. If bolts are missing or brackets are visibly damaged, call us. We'll get it right.

Open and close the door slowly. Listen for grinding, squeaking, or rattling sounds. Watch the door as it rises and falls. Does it move smoothly, or does it jerk and hesitate? Does it hang to one side? Smooth, quiet operation means the springs and tracks are balanced. Rough operation means wear is happening faster than normal. Balance problems also increase the load on your opener motor, shortening its lifespan.
Uneven movement can be a sign that one spring is weaker than the other. Springs last about 7 to 9 years in Lake Oswego's climate, depending on usage. If your door is over eight years old and you haven't replaced springs, this check is even more important.
Your opener has a red cord hanging from it. Pulling this cord disconnects the door from the opener so you can manually raise and lower it in case of power loss. Pull the cord and try to move the door up by hand. It should move smoothly without jerking. If it's hard to move or won't budge, the springs are either broken or severely imbalanced.
We take child safety seriously at Garage Door Lake Oswego. Garage doors cause more injuries to children than any other household appliance except stairs. Make sure your kids know the door is not a toy. Teach them to keep hands and toys clear. If you have young children, photo eye and auto-reverse are non-negotiable.

If any of these checks fail, don't delay. A professional inspection costs far less than an accident or emergency repair. We offer free estimates in Lake Oswego and can often schedule a same-day or next-day service. Minor adjustments and sensor repairs typically run between $150 and $350. Waiting until something breaks catastrophically can cost three times as much.
Your garage door's safety is non-negotiable. If you're unsure about any inspection step, call us at (971) 343-8987. We'll walk you through it or send a technician to handle it. Peace of mind is worth the call.
How often should I inspect my garage door for safety? Inspect your garage door monthly. Check photo eyes, test auto-reverse, and listen for unusual sounds. A visual walk-around takes five minutes and catches most problems early before repair costs spike.
What does a professional garage door safety inspection include? A professional inspection covers photo eye alignment, auto-reverse testing, spring balance and tension, track alignment, hardware tightness, opener function, and manual release operation. We also check the bottom seal and weatherstripping for gaps that affect child safety.
Can I adjust the photo eye myself? You can clean the lenses, but adjustment requires precision. Photo eyes have a specific alignment window. If cleaning doesn't fix the problem, a technician should handle the adjustment. Misaligned sensors create false safety signals.
How much does a garage door safety repair cost in Lake Oswego? Cost depends on what's broken. Photo eye cleaning is free. Sensor replacement runs $150 to $250. Spring repair or replacement costs more, typically $300 to $600 per spring. We provide a free estimate before work begins.
What's the difference between auto-reverse and photo eye safety? Photo eyes detect motion and stop the door before contact. Auto-reverse detects physical contact and reverses the door. Both are required by code. If either fails, your door becomes a hazard. Both need monthly testing.
