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.

Our technicians are on call around the clock to handle urgent situations like broken springs, doors stuck open or closed, and security concerns.

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.

If you live in the Outer Sunset or the Richmond District, you already know the drill: your car is damp in the morning, the doormat stays permanently wet, and Karl the Fog isn't just a social media mascot. he's actively working against your home. What most San Francisco homeowners don't realize is that the same marine layer rolling through the Golden Gate every evening is quietly attacking one of the most critical components of your garage door system: the springs.

How San Francisco's Climate Accelerates Spring Wear

San Francisco's average relative humidity hovers around 75% year-round, with January hitting as high as 80%. That's not just "damp". that's persistently corrosive. The fog itself isn't pure water vapor, either. Coastal fog forms when marine air mixes over cold California Current waters, and the condensation nuclei that seed those droplets are primarily composed of salt from ocean surf and spray. That means every morning burn-off deposits a fine layer of salt on every metal surface on your home's exterior. including your garage door hardware.

For homeowners in Daly City and South San Francisco, conditions are even more intense given their direct ocean exposure. But even in neighborhoods like Noe Valley or the Mission, which sit somewhat sheltered from the heaviest fog, springs still face far more moisture stress than they would in an inland city.

The practical result? Coastal salt air accelerates corrosion on bare steel springs, and homeowners in San Francisco often see springs fail 2 to 3 years earlier than the same springs would last in inland areas like Dublin or Livermore. Standard springs are rated for roughly 10,000 cycles. that's about 7,14 years of use depending on how often you open and close the door. In SF's salty, humid air, that timeline shrinks meaningfully.

Warning Signs Your Springs Are Losing the Battle

Spring failure rarely comes without warning. if you know what to look for. Check your springs during your next garage door maintenance visit or just take a look on your own:

- Visible rust or orange discoloration on the coils. this is the most obvious sign that corrosion has taken hold - A loud bang when the door is operating, or a sudden refusal to open. this often means a spring has snapped - Uneven lifting. if one side of the door rises faster than the other, a weakened spring on one side is the likely culprit - The door feels unusually heavy when you try to lift it manually after disconnecting the opener

Do the manual test right now if you haven't recently: pull the red emergency release cord on your opener, then try lifting the door by hand from the bottom. A properly balanced door should glide up smoothly and stay open on its own at about waist height. If it crashes back down or feels like you're lifting a car hood, your springs need attention.

What to Do (and What Not to Do)

Here's the honest advice: don't attempt to replace or adjust garage door springs yourself. Springs store an enormous amount of tension. enough to cause serious injury if released suddenly without the right tools and training. This is one of those jobs where the risk simply isn't worth it.

What you *can* do on your own to extend spring life:

Lubricate Every 3,6 Months

Apply a silicone-based spray or white lithium grease to your springs every 3 to 6 months. This creates a moisture-resistant film and reduces friction. Critically, avoid standard WD-40. it's a degreaser, not a lasting lubricant, and can actually strip away protective coatings and attract dirt over time.

Choose the Right Springs When Replacing

If you're at the point of replacement, ask specifically about galvanized or oil-tempered springs. These are treated to resist oxidation and hold up significantly better in coastal and humid environments like ours. When Garage Door San Francisco replaces springs in homes near the water, this is the standard recommendation.

Replace Both Springs at Once

If one spring breaks, the other is almost certainly close behind. they've lived the same life under the same conditions. Replacing both at the same time ensures balanced operation and saves you a second service call in six months.

For homes in the Marina District or along the Great Highway, where the fog is heaviest and most persistent, annual spring inspections are worth adding to your routine. Check out our FAQ page for more on how often different components need attention in the Bay Area climate.

Don't Wait for the Loud Bang

A broken spring is one of the most common reasons homeowners get stuck. either locked out of their garage or with a door that won't close and secure the space. It's also one of the most preventable failures with even minimal regular attention.

If you haven't had your springs looked at in the last couple of years, or you've noticed any rust or resistance when the door operates, schedule a service call before the problem becomes an emergency. A proactive inspection is far cheaper than a same-day emergency repair. and it'll give you a clear picture of how much life is left in the system.

Frequently Asked Questions

Q: How can I tell if my garage door springs are the torsion type or extension type? A: Torsion springs are mounted horizontally above the door opening on a metal shaft. you'll see one or two large coiled cylinders. Extension springs run parallel to the door tracks on either side. Torsion springs are more common on heavier doors and are generally considered safer and longer-lasting, which makes them a smart choice for SF homes with solid wood or insulated steel doors.

Q: My spring looks fine but my door is still struggling. Could something else be the problem? A: Absolutely. Worn rollers, misaligned tracks, frayed cables, or an underpowered opener can all make a door feel sluggish or unbalanced even when the springs aren't fully broken. In SF's climate, rollers and hinges also take on corrosion, so it's worth having a technician look at the full system rather than assuming one component is the culprit.

Q: How much does a spring replacement typically cost in San Francisco? A: Costs vary based on spring type, door weight, and whether you're replacing one or both springs. As a general reference, a garage door spring repair or coil replacement in SF can run anywhere from $200 to $500. That range accounts for differences in door size, material, and labor. Getting an upfront estimate before work begins is always the right move.
