Garage Door Maintenance Tips That Save San Francisco Homeowners Money

A lube and tune from $95 once a year is the cheapest thing you'll ever do to a garage door. The repairs it heads off start at $189 for a spring and from $149 for an opener part. We fix doors all over San Francisco from our shop at 1726 Great Hwy, and most of the 2 AM calls we take started as a squeak someone lived with for a year.

Why San Francisco Doors Wear Out Faster

Salt air. Our shop is a block from Ocean Beach, and everything steel on a Sunset or Richmond District door rusts years ahead of the same part in Noe Valley. Fog condenses on the springs at night, the salt pits the wire, and the pits are where the spring eventually cracks. Standard springs that should go 7 to 10 years often quit in 4 to 6 out here. Cables fray at the bottom brackets first, where water pools. Rollers seize. East of Twin Peaks the weather is kinder, but the hills aren't. An opener on a steep Bernal Heights or Castro driveway lifts a heavy old door every day, and it wears its gears out sooner. Doors in the Marina and anywhere else near the bay get their own dose of salt.

The 5-Minute Check You Can Do Every Month

Stand inside the garage and run the door once with the opener. Watch and listen. A healthy door moves at one speed, sits level in the opening, and makes the same sound it made last month. Jerking, a slow spot in the travel, or a door that rises crooked means something's binding or a cable is stretching. Then look at the two small sensors near the floor. Wipe the lenses with a dry cloth. Both lights should be steady. Wave a broom handle through the beam while the door is closing and it should reverse right away. If it doesn't, stop using the door until the sensors are fixed. That's a realignment from $90 on our end, and it's the one part of the door that can hurt a kid or a dog.

The Balance Test, Twice a Year

Pull the red release cord with the door fully closed, then lift the door by hand to about waist height and let go. It should stay put, or drift an inch or two. A door that falls or shoots up has springs that are out of tension, and every cycle from then on is the opener hauling weight it wasn't built for. Don't touch the springs yourself. Call, and we'll re-tension them or tell you they're due. A spring and cable inspection starts at $85 and includes the re-tension. One warning. If you ever hear a loud bang from the garage, the spring is already gone. Leave the door closed and don't pull the release.

Tighten What Vibrates Loose

Every open and close shakes the door, and over a year the hinge bolts, the track brackets, and the bolts holding the opener to the ceiling all back off a turn or two. Twice a year, snug them with a socket wrench. Snug, not cranked. The lag bolts that hold the vertical tracks to the framing matter most, since a track that's drifted even a quarter inch makes the rollers scrape. On Sunset tuck-unders, that scraping goes straight through the joists into the bedroom above. If a bolt spins in a stripped hole, leave it for us.

Lubricate the Right Parts With the Right Stuff

Use a garage-door lubricant, either silicone or white lithium. Skip WD-40, which strips the grease that's already there and collects grit. Hit the hinges, the roller stems, the spring coils, and the opener rail. Leave the track dry. Grease in the track makes rollers slide instead of roll. On the coast, oiling the spring coils two or three times a year is the best thing you can do for spring life, because it puts a barrier between the steel and the salt.

Know What's Living on Borrowed Time

Rollers last 5 to 7 years if they're steel, longer if they're nylon. A full set of nylon rollers starts at $130 and is the quietest money you'll spend on the door. Springs are rated for about 10,000 cycles, which at four opens a day is 7 years inland and often 4 or 5 near the beach. Lift cables show rust bloom or broken strands at the bottom bracket before they go. Replace the pair (from $160) when you see either. Opener backup batteries fade in 2 to 4 years, usually with no warning light. Openers themselves: past 15 or 20 years, a chain-drive unit with a failing board usually isn't worth putting $300 into, and we'll say so. Our opener evaluation starts at $45 and comes off the bill if you do the work with us.

What a Tune-Up Actually Covers

Our 20-point lube and tune starts at $95 for one door. The tech does everything above plus the things that need tools: spring tension, cable condition, opener force and travel limits, the auto-reverse test, and a load test on the backup battery. You get a short list of what's fine, what's wearing, and what it'll cost if you want it handled. Most of the time the list is short. Once a year is right for most San Francisco doors. Within about ten blocks of the ocean, twice a year pays.

When Maintenance Stops Making Sense

If the door is a 1940s wood one-piece with rot at the bottom rail, or the panels have rusted through, a tune-up is a bandage. A new single-car steel door starts at $1,200 installed, and past a certain point that's the cheaper decade. We'll tell you which side of that line your door is on. Our garage door replacement page covers what's involved.
