Garage Door Safety in Stratford, NH: What Stops Accidents Before They Happen
2026-09-10 4 min read
In our years serving Stratford, we've seen this problem again and again: homeowners treat their garage doors like they're invincible. A door that weighs 300 to 500 pounds moves with real force, and when safety features fail, people get hurt. The good news? Most accidents are preventable. Garage door safety in Stratford starts with understanding what your opener should do and then making sure it actually does it.
The Two Critical Safety Features You Need Right Now
Your garage door opener has two mandatory safety systems. The first is auto-reverse, a mechanism that reverses the door's direction if it hits an obstacle. When your door closes and suddenly encounters a car, a pet, or a child's hand, the motor stops and reverses within about half a second. The second is the photo eye, a pair of sensors positioned a few inches above the floor on each side of the opening. These infrared beams detect motion in the door's path and prevent closing if anything breaks the beam.
Neither of these features is optional. Federal law has required them since 1993. If your opener doesn't have both, you're living with real risk.
The photo eye is especially easy to overlook. These sensors can get dusty, misaligned, or blocked by a leaf or spider web. A single blockage means your door won't close at all, which frustrates homeowners into disabling the sensor entirely. Don't do that. If your photo eyes aren't working, call us to realign or replace them. Same-day service is usually available.
Auto-Reverse Testing: A Simple Habit That Matters
Test your auto-reverse once a month. Place a 2x4 board flat on the ground in the door's path and press the close button. The door should touch the board and reverse immediately. It should not sit there grinding or applying pressure. If it hesitates, applies force, or reverses slowly, your opener needs professional attention.
We recommend testing this yourself because you'll build confidence in what "normal" feels like. Any change in how quickly or decisively the door reverses is worth investigating.

Child Safety and Pinch Points
Garage doors have pinch points along the sides and edges where the panels bend. A child's finger can slip into these gaps. Your door opener's auto-reverse helps, but it's not a substitute for supervision. Teach children never to stand under a closing door, and never let them play with the remote.

Regular Maintenance Prevents Safety Failures
The best way to ensure your safety features work is maintenance. Springs lose tension over time. Openers accumulate dust and wear. Cables fray. A door that was safe two years ago might not be safe today. We recommend an annual tune-up, which includes testing auto-reverse, checking photo eye alignment, inspecting springs for wear, and lubricating moving parts.
If you haven't had your system inspected in more than a year, start there. The cost of a maintenance visit is far less than the cost of an injury claim or emergency repair. Our garage door maintenance guide walks through what a proper tune-up includes.
When Safety Features Fail: What to Do
If your auto-reverse isn't working or your photo eyes won't align, your door is unsafe to use. Don't try to work around it. Contact a professional for an estimate. Replacing sensors costs far less than replacing an opener, and we can often repair the issue same-day if you call in the morning.
We also service battery backup systems, which keep your door operational during power outages. If you're concerned about being trapped in your garage or unable to open it during an emergency, learn more about garage door opener battery backup and whether it makes sense for your situation.

Frequently Asked Questions
How often should I test my garage door's auto-reverse? Test auto-reverse at least once a month using a 2x4 board on the ground. The door should stop and reverse immediately upon contact. Any delay or grinding noise means the opener needs service right away.
What does a photo eye do? Photo eyes are infrared sensors that detect movement in the door's path. If the beam is broken while the door is closing, the door stops and reverses. Both sensors must be aligned and clean for the system to work.
Can I realign photo eyes myself? You can clean the lens with a soft cloth, but realignment requires precision. Misaligned sensors may not trigger at all. It's safer to have a professional handle it, especially if the door won't close properly.
What happens if my photo eye is broken? A broken photo eye means your door won't close, or it will close without the safety sensor active. This is a safety hazard. Contact a technician to replace the sensor. Disabling it to make the door work is dangerous and illegal.
How much does a safety feature replacement cost? Photo eye replacement typically costs $100 to $200. Auto-reverse repairs vary by opener type. Call for a free estimate: 19789615536.
