Here's what most homeowners don't realize about garage door safety: your garage door is one of the heaviest moving objects in your home, and a single failure can cause serious injury. Many Exeter residents assume their door is safe because it opens and closes. That's a dangerous gap in thinking. A properly functioning garage door requires regular inspections of critical safety features that most people overlook entirely.
The auto-reverse feature is non-negotiable. This safety mechanism forces your garage door to reverse direction if it encounters an obstacle while closing. Federal law has required this feature since 1993, yet plenty of older doors in Exeter haven't been updated or maintained properly.
Your auto-reverse system works through two methods: mechanical force sensors and photo eye sensors. The mechanical sensors detect physical resistance. The photo eye sensors use invisible infrared beams to detect motion. If either system fails, your door won't stop or reverse when it should. That's when a closing door can trap a child, a pet, or even cause fatal injury.
Testing your auto-reverse takes 30 seconds. Place a 2x4 block on the garage floor beneath the closing door. If the door doesn't reverse when it hits the block, you need professional attention immediately. Don't rely on this yourself if you're unsure. Call Garage Door Exeter or a qualified technician to schedule a free safety inspection before someone gets hurt.
Photo eyes sit about 6 inches above the garage floor on both sides of your door opening. Their job is simple but critical: stop the door from closing if anything passes through the beam. Dust, spider webs, misalignment, or dead insects can block these sensors and render them useless.
Check your photo eyes monthly. Make sure nothing blocks the lenses. If the lights on the photo eye units aren't glowing steady green (or your opener's specific indicator), the sensors aren't working. Realigning photo eyes requires precision and shouldn't be a DIY project. A small angle shift breaks the beam connection.
This is one reason why regular maintenance matters so much. When we perform routine maintenance, we clean and align photo eyes as standard practice. It costs far less than an emergency repair or medical bills.

Garage doors have multiple pinch points where small fingers can get crushed. The vertical tracks, the horizontal sections, and the areas where panels meet create real dangers for young children. Add in the fact that many kids find the door mechanism fascinating, and you have a recipe for injury.
Never let children operate the garage door. Don't give kids the remote. Teach them that the garage door is not a toy. If you have young children at home, consider upgrading to an opener with a wall button rather than a remote. Wall buttons are harder for children to reach and access.
Understanding your door's full feature set helps protect your family. Some newer openers include child safety locks that disable remote operation. If you have an older system, ask about upgrading your opener. The cost of a new opener is insignificant compared to preventing serious injury.
Garage door springs are under extreme tension. A broken spring doesn't just prevent your door from working. It can snap violently and cause lacerations or crush injuries. Springs last roughly 7 to 9 years under normal use in our New England climate, where winter weather puts extra stress on the system.
Never attempt to replace springs yourself. This isn't a DIY repair. The tension is dangerous, and improper installation creates ongoing safety hazards. When your door won't open or closes unevenly, springs are often the culprit. Get a professional estimate before proceeding. Our pricing guide explains what garage door repair actually costs so there are no surprises.
Cold temperatures make metal brittle and lubrication stiffer. Ice buildup can jam door movement. Spring failure happens more often in winter because the cold contracts metal and increases tension. If you live in Exeter or nearby towns like Newbury or Salisbury, winter maintenance is non-negotiable.
Preparing your garage door for winter with proper lubrication and inspection prevents most cold-weather failures. Don't wait until January when ice hits.
Safety isn't something you can eyeball and guess about. Book a professional inspection. We'll test your auto-reverse, check your photo eyes, inspect springs and cables, and verify all safety features are working as designed. Most inspections take 30 minutes and give you clear answers about what needs attention.

A garage door that works is good. A garage door that works safely is everything. Let's get yours right.
What's the difference between mechanical sensors and photo eye sensors? Mechanical sensors detect physical force when the door hits an object. Photo eyes use infrared beams to sense motion. Both are required by law. A properly functioning system uses both for redundancy and maximum protection.
How often should I test my auto-reverse feature? Test it monthly by placing a 2x4 under the closing door. The door must reverse immediately upon contact. If it doesn't, stop using the door and call a professional. A failing auto-reverse is a serious safety issue.
Can I adjust my photo eyes myself? You can clean them and check for obstructions, but alignment requires precision equipment. Misaligned photo eyes create a false sense of safety. Have a professional align them if they're not working properly.
Why shouldn't I replace garage door springs myself? Springs are under extreme tension, typically 200 to 400 pounds of force. A broken spring or improper installation can cause serious injury. This job requires specialized tools, knowledge, and training. Always hire a professional.
How does winter affect garage door safety in Exeter? Cold temperatures make springs more brittle and increase failure risk. Ice and snow can jam the door. Lubrication becomes stiffer in cold. Regular winter maintenance prevents safety failures during the season when you need your door most.
