Most single garage door repairs in San Francisco start at $130, parts and labor included. Opener repairs start lowest, spring and cable work costs more, and structural work such as panels and tracks bent by a car tap costs the most. A full door replacement runs from $1,200 installed. Every number on this page is a real starting price from our own San Francisco service work, updated quarterly.
A quote isn't a single mystery number. When we price a spring replacement, for example, the total breaks into parts you can ask about line by line:
What should not be in the quote: trip fees for showing up, "emergency multipliers" that double the price at night, or add-ons invented on your driveway. We quote one exact number after diagnosis, you approve it, and that's the number on the invoice — at 2 PM or 2 AM. That same no-surcharge logic runs our 24/7 emergency garage door repair calls — nights, weekends, and holidays included.
The most expensive mistake isn't overpaying for a repair — it's repairing a door that should have been replaced, one part at a time. Run through these five questions:
Bring us a borderline case and we'll price both paths in the same visit, in writing, and tell you which one we'd pick for our own garage.
National cost articles average in cities where a technician parks in a driveway in front of a detached garage. San Francisco is a different job site:
The starting prices in the index below already include all of that. They're San Francisco numbers, not national averages with a markup.
The garage door trade has a well-documented bait-and-switch problem: a $39 "service special" that becomes a $900 invoice. Three habits keep you safe with any company, including us:
Every price below is where an Alfonso Garage Door job starts across San Francisco and the surrounding Bay Area, parts plus labor. You hear the exact price before any work starts. What can raise the price: two springs instead of one, a heavy, insulated, wood or oversized door, worn cables, rollers or drums we find on the visit, or a part we have to order. National cost guides quote national averages. San Francisco labor and coastal-grade hardware cost more, and these prices include both. Updated quarterly.

Safety note: garage door springs and cables are under extreme tension and are the leading cause of garage-door injuries tracked by industry safety standards (DASMA / UL 325). Spring and cable pricing above always includes professional installation. We do not sell parts for DIY spring work.

Most single repairs in San Francisco start at $130 with parts and labor. Spring replacement typically starts at $189 for a single torsion spring, cable pairs from $160, opener repairs from $149, and track realignment from $130, and panel replacement from $250. Anything quoted far outside those bands — in either direction — deserves a second opinion.
Three reasons: labor costs reflect Bay Area wages; the housing stock is harder — garage-under-living-space row houses, heavy pre-1980 wood doors, out-of-square openings; and coastal hardware matters — near Ocean Beach, salt air destroys builder-grade springs and cables early, so corrosion-resistant parts are the right spec. National guides average in markets with none of those factors.
Diagnosis starts at $45 depending on distance and time of day, and it's credited toward the repair if you go ahead with the work — so if we fix the door, the diagnostic effectively costs nothing. You'll know the exact repair price before we start, in writing.
No multiplier. We're genuinely open 24/7, and a 2 AM spring replacement uses the same starting prices as a 2 PM one. An after-hours diagnostic costs more, and the repair itself is priced the same. Companies that double prices at night are pricing your panic, not the work.
When the repair crosses about half the cost of a comparable new door installed, when the door is past 20 years old, or when you're on your third paid repair in two years. A new single door in San Francisco starts at $1,200 installed and resets every wear component at once. We'll price both paths in writing in the same visit if it's a close call.
The advertised number is a trip fee, not a repair price. Once the truck is in your driveway, the actual work gets priced on the spot — often with invented 'required' add-ons like full spring conversions or safety packages. Protect yourself by getting the total in writing before any work starts and requiring written approval for any change. That's how we operate by default.
Often yes for sudden events — a car backing into the door, storm damage, vandalism — and usually no for wear and tear like a fatigued spring. If a vehicle hit the door, photograph everything before repairs and call your insurer; we can provide an itemized written quote that works for claims documentation.
Like-for-like door replacement in an existing opening usually doesn't require a permit, but structural changes to the opening, or work tied to a larger project like a garage conversion or seismic retrofit, can. We'll flag it before quoting if your job is one of the exceptions.
Cheapest: remote programming from $40, sensor realignment from $90, and a lube and tune from $95. Most expensive short of replacement: multi-panel damage or a bent track system after a vehicle strike, priced after we see the door. The pattern worth knowing: almost every expensive repair started as a cheap one that ran for months — a $95 tune-up catches most of them early.
They come from our own San Francisco service records and are reviewed quarterly — the 'last updated' date sits on the price index below. Your exact price depends on your door's size, weight, and parts, which is why we confirm every job with a written quote before starting. The starting prices tell you where a job begins. The quote tells you your number.
Five things: torsion versus extension springs, the cycle rating, whether the door needs one spring or two, the door's size and weight, and coated or galvanized hardware for homes near the ocean. A single torsion spring starts at $189 installed and a pair starts at $320. Heavy wood doors and high-cycle springs cost more than those starting prices.
On a two-spring door, almost always. Both springs went in on the same day and have done the same number of cycles, so when one lets go from age and salt-air corrosion the other is close behind. Replacing the pair from $320 costs more today but saves a second service call, and the door balances properly.
We do not recommend it. A torsion spring holds enough stored energy to break bones when it lets go during an amateur repair, and a spring sized or wound wrong leaves the door unbalanced, which then chews up the opener. Most of what you pay a pro for is doing the job safely with the right spring for your door.
