Most homeowners in Keller don't realize their garage door poses a real safety risk until something goes wrong. The good news? Five simple checks catch problems before they hurt anyone. This guide walks you through what matters most, what costs you should expect, and when to call a professional.
Your garage door opener has a safety feature called auto-reverse. When the door hits an obstacle while closing, it should stop and reverse direction automatically. This is your first line of defense against child safety hazards and pinched fingers.
Test it yourself: Place a wooden block or rolled-up towel under the closing door. When the door contacts it, the door should reverse. If it doesn't, stop using that door and call us for a same-day inspection. A broken auto-reverse is a liability waiting to happen.
The auto-reverse mechanism relies on your door's sensors and opener logic board working together. If either fails, the door becomes dangerous. We've seen this happen in homes across Keller and Arlington after years of neglect.
Two small sensors live on either side of your garage door opening, about 6 inches from the ground. These photo eyes detect motion and objects in the door's path. Misaligned photo eyes don't work, which means your auto-reverse might not trigger.
Check both sensors today. They should have a small light indicator (usually red or green). Debris, spider webs, or bumped brackets throw them out of alignment. Wipe them clean with a soft cloth. If the light stays off after cleaning, the sensors need replacement.
We often find photo eye issues during our safety inspections. Many homeowners don't even know these sensors exist until something breaks.

Garage door springs carry roughly 300 to 400 pounds of tension. They're designed to last 7 to 9 years under normal use. Once they age or break, the door becomes unbalanced and harder to open or close safely.
Test your spring balance by opening the door manually (with the opener unplugged). A balanced door should stay roughly in place. If it slams down or feels impossibly heavy, your springs are failing. Never try to adjust or replace springs yourself. That's a job for trained technicians with the right tools.
Broken or weakening springs increase the risk of the door falling unexpectedly. This is especially dangerous for child safety in homes where kids play in the garage.
Look at the hinges, brackets, and rollers holding your door. Rust, cracks, or loose fasteners weaken the system. Weather stripping around the perimeter should seal gaps, not just sit there. Worn stripping lets pests and drafts in, but it also affects how smoothly the door operates.
If your door is over 10 years old, hardware replacement often makes sense alongside a safety checkup. We've written about weather stripping replacement in detail here, which covers when and why it matters.
Some safety checks you can do yourself. Others require proper diagnostic tools and training. If you notice any of these, schedule a professional inspection right away:
Your door closes unevenly or binds on one side. The opener sounds strained or makes grinding noises. Springs show visible rust, cracks, or wear. Photo eyes won't align no matter how you clean them. The door feels unstable or wobbles during operation.
We offer free estimates for safety concerns, and we can often fit same-day appointments in Keller. Check our full list of safety services to see what applies to your situation.
Start with the auto-reverse test and photo eye check. Both take five minutes. If those pass, inspect the springs and hardware visually. Document any concerns with photos. Then contact us for a free estimate. We'll walk through exactly what needs attention and give you honest pricing with no upsell pressure.

How often should I test my garage door's auto-reverse? Test it monthly. Place an object under the door as it closes; it should stop and reverse. If it doesn't, stop using the door and call a technician immediately. This is the most critical safety feature.
What does a photo eye do, and why does it matter? Photo eyes detect objects and motion in the door's path. They work with your auto-reverse to prevent the door from closing on people or pets. Misaligned or dirty sensors disable this protection, creating a serious safety hazard.
Can I replace garage door springs myself? No. Springs hold hundreds of pounds of tension and can cause serious injury if mishandled. Always hire a trained professional. We handle spring replacement safely and quickly across Keller.
How much does a garage door safety inspection cost? We offer free estimates on all safety concerns. Inspections take about 30 minutes. During that time, we identify problems and explain repair costs upfront with no hidden fees or surprise charges.
What's the difference between a safety inspection and regular maintenance? A safety inspection focuses on hazards: springs, sensors, auto-reverse, and structural integrity. Maintenance covers lubrication, weatherstripping, and preventive care. Both matter, but safety comes first.
