My garage door opener sensor won't stop blinking. Is this a safety issue?

Those blinking sensors are your door's safety guards, and they take misalignment seriously. Dust, condensation from our Bay Area fog, or a nudged bracket can throw them out of whack. Before calling us, check that both sensors face each other squarely and wipe the lenses clean. If that doesn't help, the sensors themselves may need replacing—usually around $150–$300 for the pair. It's a safety feature worth getting right, so don't ignore it.

How do I know if my garage door springs are actually broken, or if something else is wrong?

A broken spring usually means your door feels heavy as a truck when you lift it manually, or the opener struggles and may not open it at all. You might hear a loud bang from the garage—that's the spring snapping. Other issues like a bent track or cable problems feel different; the door moves unevenly or gets stuck partway. Springs typically last 7–10 years depending on use. If you're unsure, we're happy to do a free inspection before recommending anything.

I lost my remote and my keypad stopped working. Can you reprogram them for me?

Absolutely. Reprogramming is straightforward and usually takes under an hour. We'll sync new remotes to your opener and reset your keypad with a fresh code you choose. Bring your garage door opener model number if you have it handy, but we can work without it. Costs vary by opener type, so give us a call for a quote. Having a backup remote is smart—Colma weather and regular use can wear them out eventually.

Are you licensed and insured to work on garage doors in Colma?

Yes. We're fully licensed, bonded, and insured to operate in Colma and surrounding areas. Your protection matters to us, which is why we carry general liability and workers' compensation coverage on every job. You can ask for proof of our credentials anytime—we keep everything current and transparent. Working with a licensed contractor gives you peace of mind and legal recourse if something goes wrong.

Do you offer financing options or payment plans?

We understand that spring replacement or a new door installation isn't always budgeted for right away. We work with several financing partners to offer flexible payment plans with competitive rates. Most jobs can be financed for 12–60 months depending on the amount and your approval. Call us to discuss your situation and what options make sense for your budget.

What exactly does your warranty cover, and for how long?

Our warranty typically covers parts and labor for one year on most repairs—springs, openers, sensors, and hardware. If we install a new door, the manufacturer's warranty usually runs 10–15 years on the panels and structure, plus our one-year labor guarantee. Wear items like weatherstripping and paint are generally excluded. We'll detail your specific coverage in writing before we start. Always keep your paperwork so you know what's protected.

What R-value insulation should I choose for a garage door in Colma?

Colma's coastal climate means mild winters and cool summers, but fog and salt air can affect an uninsulated door. An R-value of 8–12 is solid for our area—it keeps the garage more comfortable, reduces noise, and protects the door from moisture damage. If you're in a spot with ocean winds or your garage is attached and heated, R-16 is worth the extra cost. We can walk you through the trade-off between insulation, weight, and your opener's capacity.

Should I install a battery backup for my garage door opener?

Battery backup is handy during the occasional power outage—it lets you open or close the door a handful of times so you're not stuck. Colma doesn't see frequent blackouts, but backup systems cost $300–$500 and give you peace of mind. They work best if your door and opener are in good shape; a struggling opener won't benefit much. If you're worried about being locked out during an outage, it's a reasonable investment.

When should I replace my garage door cables, and why is it dangerous to wait?

Cables typically last 5–7 years and wear faster if you use your door heavily. Fraying, rust, or visible kinks mean replacement is overdue. A snapped cable puts all the door's weight on the springs, stressing them dangerously and risking a sudden drop. Never try to replace cables yourself—they're under extreme tension and can cause serious injury. We replace them in under two hours for $200–$400 per cable, depending on your door. Catching wear early saves you from an emergency.

# Surge Protection: Protecting Your Family

Power surges are one of the most overlooked threats to your garage door opener and, by extension, your family's safety and security. A single surge can destroy your opener's electronic components, disable safety features, and leave your home vulnerable. In this essential guide, we'll explain why surge protection matters and how to safeguard your family.

Understanding Power Surges

A power surge is a sudden spike in electrical voltage that exceeds the normal flow of electricity. These surges can be caused by:

External Sources: - Lightning strikes (even miles away) - Power grid switching by utility companies - Downed power lines - Large appliances cycling on and off in your neighborhood

Internal Sources: - Air conditioners starting up - Refrigerators and freezers cycling - Power tools - Hair dryers and space heaters

While major surges from lightning are dramatic and obvious, it's the smaller, repeated surges that often cause the most cumulative damage to electronics over time.

How Surges Affect Your Garage Door System

Modern garage door openers are sophisticated electronic devices with circuit boards, sensors, and microprocessors. These components are vulnerable to voltage spikes in several ways:

Immediate Damage: - Fried circuit boards - Destroyed motor controls - Disabled safety sensors - Burnt-out transformers

Cumulative Damage: - Degraded electronic components - Intermittent operation issues - Shortened equipment lifespan - Unreliable safety features

The most concerning aspect is that surge damage can disable safety features without obvious signs. Your door might still operate, but the auto-reverse function or photo-eye sensors might be compromised – creating a serious hazard for your family.

The True Cost of Surge Damage

Beyond the expense of replacing a damaged opener ($400-$800 or more), consider:

- Security Risks: A non-functional opener may leave your garage door stuck open or impossible to secure - Safety Hazards: Damaged safety features can lead to injuries - Inconvenience: Being unable to access or secure your garage - Secondary Damage: Surges can travel through wiring and damage other connected systems

Protection Strategies

Whole-House Surge Protection

The most comprehensive solution is a whole-house surge protector installed at your main electrical panel. These devices: - Protect all connected devices and appliances - Handle large surges from external sources - Typically cost $200-$500 plus installation - Should be installed by a licensed electrician

Point-of-Use Surge Protectors

For the garage specifically, install a surge protector at the outlet powering your opener: - Look for protectors rated for at least 1,000 joules - Choose models with indicator lights showing protection status - Replace after a major surge event - Don't use basic power strips – use true surge protectors

Dedicated Circuit

Having your garage door opener on its own dedicated circuit provides additional protection: - Isolates the opener from surges caused by other devices - Provides consistent, clean power - Reduces interference from other appliances

Battery Backup Systems

Many modern openers include or can be fitted with battery backup: - Maintains operation during power outages - Some provide surge protection as well - Ensures you're never locked out during emergencies

Signs of Surge Damage

Watch for these indicators that your opener may have suffered surge damage:

- Opener doesn't respond to remote or wall button - Door moves erratically or partially - Lights on the opener are off or flickering - Strange noises from the motor unit - Safety sensors not detecting obstacles - Remote range has decreased significantly - Opener cycles on and off randomly

What to Do After a Surge

If you suspect surge damage:

1. Don't operate the door repeatedly – this can cause additional damage 2. Check the outlet and circuit breaker – ensure power is reaching the opener 3. Test safety features – verify the auto-reverse and sensors work before regular use 4. Have a professional inspection – hidden damage may not be immediately apparent

Preventive Maintenance

Regular maintenance helps identify surge damage early: - Monthly testing of safety features - Annual professional inspection - Immediate attention to any operational changes - Keep surge protectors up to date

Our Protection Recommendations

At Garage Door Company Colma, we recommend: 1. Installing a whole-house surge protector 2. Adding a point-of-use protector for your garage outlet 3. Consider a battery backup opener 4. Annual inspections to catch damage early

Our technicians can assess your current protection level and recommend appropriate solutions for your home and budget.
