How long does it take to install a new garage door?

A standard garage door installation typically takes 3-5 hours for a single door and 4-6 hours for a double door. This includes removing the old door, installing the new one, setting up the opener, and testing all safety features. Custom doors or doors requiring additional framing modifications may take longer. We schedule installations in the morning to ensure completion the same day. Our technicians arrive with all necessary equipment and parts to minimize delays.

What should I do if my garage door won't open or close?

First, check the obvious: ensure the opener is plugged in and the remote batteries aren't dead. Look at the photoelectric sensors near the floor—they should both have steady lights. If one is blinking, try cleaning the lens and realigning it. Check if the door is locked manually. Try using the wall button instead of the remote. If these steps don't work, pull the emergency release cord to operate the door manually (only when fully closed) and call us for service. Never attempt to repair springs or cables yourself—they're under extreme tension and can cause serious injury.

Yes! We provide 24/7 emergency garage door repair service throughout San Francisco and the Bay Area. Our technicians are on call around the clock to handle urgent situations like broken springs, doors stuck open or closed, and security concerns. We understand that a malfunctioning garage door can be a safety issue or prevent you from accessing your vehicle. Call 510-737-5655 any time, day or night, for fast emergency response.

How often should I have my garage door serviced?

Regular maintenance includes lubricating moving parts, checking spring tension, testing safety features, tightening hardware, and inspecting cables and rollers.

Let me cut through the confusion about garage door safety in San Francisco. After 15 years on service calls across the city and Oakland, I've seen what works and what doesn't. The truth: most homeowners have no idea their garage door can crush a car or trap a child. We're talking about a 400-pound panel moving on exposed springs that store massive energy. This post covers what actually matters.

The Real Dangers Most San Francisco Homeowners Miss

Your garage door is the heaviest moving object in your home. It operates under extreme tension from springs that stay loaded even when the door sits closed. That's not meant to scare you. It's meant to clarify why safety features exist.

The biggest hazard isn't what you'd expect. It's not the door closing on your head (though that's bad). It's the springs. A single torsion spring can store enough energy to launch a wrench across a room. I've seen it happen. Springs last 7 to 9 years under normal San Francisco conditions, and when they fail, they fail violently.

The second danger is entrapment. Children have been seriously injured when fingers get caught in panels or tracks. A child's hand can slip into a gap before you realize it's happening. That's why photo eye sensors and auto-reverse mechanisms exist. They're not luxury add-ons; they're legal requirements.

Safety Features That Actually Work

The photo eye is your first line of defense. This two-sensor setup sits about six inches above the ground on both sides of your garage opening. If anything blocks the infrared beam while the door closes, the door stops and reverses. It's been required by law since the 1990s, but many older doors lack one or have a broken sensor.

Auto-reverse is the backup system. Modern openers have a mechanical force-limit feature that detects resistance during closing. If something blocks the door, it reverses within two seconds. We test this monthly on most service calls, and I'm shocked how many homeowners never knew their door had this feature.

Check your door's manual release lever. Every garage door opener has a red cord that hangs from the carriage. Pull it if you lose power or get stuck. Many people don't know it exists. In an emergency, that cord is your lifeline.

The emergency stop button should be mounted inside your home, away from the door itself. It cuts power instantly. This is especially important if you have young children or pets. Test it quarterly.

Child Safety: The Conversation Most Parents Avoid

Kids are curious. They see the door move and want to push buttons or stick their hands near the tracks. Without proper safety measures, this ends badly.

Keep the remote control away from children. A child pressing the button repeatedly while standing under a closing door is a nightmare scenario. Same logic applies to wall-mounted openers inside the garage. Install them at least five feet high.

Never let children play near the door while it's operating. Sounds obvious, but I've seen it. The force of a closing door is equivalent to a small car falling. No exaggeration.

If you have garage door safety concerns or an older system without modern sensors, schedule a free quote to get a full safety inspection. Most estimates take 15 minutes, and we can often upgrade sensors on the same day.

Maintenance Keeps Everything Functioning

A well-maintained door is a safe door. Springs, cables, and rollers wear gradually. When they fail, the auto-reverse and photo eye can't compensate.

Read our detailed maintenance guide for the full scope. The short version: lubricate hardware monthly, test your safety features quarterly, and have springs inspected annually. Preventive maintenance costs far less than emergency repairs.

If you've never had a professional safety inspection, that's your first step. We can walk through every component and identify what's working and what's not. Costs vary based on what needs attention. Check our pricing guide for typical estimates in San Francisco.

When to Call a Professional

Never attempt to adjust or replace springs yourself. Full stop. That's the number one mistake homeowners make. Springs are under extreme tension. A slip means serious injury or death.

If your photo eye is misaligned, a professional can recalibrate it in minutes. If your auto-reverse isn't responding, the opener may need adjustment or replacement.

Strange noises, jerky movement, or doors that close unevenly all signal safety issues. These problems affect how the safety systems function.

Garage Door San Francisco handles all safety inspections, sensor repairs, and opener upgrades for homes across San Francisco and the surrounding area. Call us at (510) 737-5655 for a same-day estimate, or reach out online to describe your specific concerns.

Your family's safety depends on a door that stops when it should and reverses when needed. Don't ignore warning signs. Get it checked.

Frequently Asked Questions

What's the difference between auto-reverse and photo eye safety? Photo eye sensors detect physical obstructions using infrared beams. Auto-reverse is a mechanical force limit that stops the door if it encounters resistance. Both are required by law. They work together, not instead of each other.

How often should I test my garage door safety features? Test your photo eye monthly by placing an object in the door's path while it closes. Test auto-reverse the same way. If the door doesn't reverse within two seconds, call a technician immediately.

Is my older San Francisco garage door still safe to use? Doors manufactured before 2000 may lack modern safety features. We can retrofit sensors and openers to bring older doors up to current safety standards. Get a professional assessment to know for sure.

What should I do if my springs break? Stop using the door. Do not attempt DIY repair. Call a professional immediately. Broken springs prevent proper auto-reverse function and pose entrapment risks. This is a same-day repair situation.

Can I install safety sensors myself? Photo eyes require precise alignment and proper wiring. Misalignment renders them useless. Professional installation ensures your safety system works when you need it most.
