Garage Door Spring Repair & Replacement in San Francisco, CA
A snapped torsion spring is the top reason a San Francisco door goes dead, and the loud bang from the garage is usually the moment it lets go. We replace torsion and extension springs, sized to your specific door, the same day across the city.
Why San Francisco homes need spring repair done right
Salt air shortens spring life here in a way it doesn't inland — corrosion pits the coil, concentrates stress, and brings a spring to failure well before its rated cycle count near Sea Cliff or the Presidio. Add a steep-grade door that leans on its counterbalance every cycle, and springs in San Francisco simply work harder and rust faster. We replace them in pairs, measure wire size, length and inside diameter to match your door's real weight, and offer coated high-cycle springs that stand up better to the coast, so you're not back to a dead door in a year.
A garage door spring counterbalances a door that can weigh 150–400 lbs, and it stores enormous energy under tension. When it snaps you'll hear a loud bang and the door becomes a dead weight the opener can't lift. Because winding a spring is genuinely dangerous, this is the repair to leave to a certified technician — we carry a full range of torsion and extension springs and replace them safely, in pairs, the same day.

What we service in San Francisco
What to expect on your San Francisco visit
- 1
Identify the spring system
Torsion (shaft above the door) and extension (along the tracks) springs are sized to your door's exact weight, height and cycle needs — we measure wire size, length and inside diameter to match.
- 2
Replace in pairs
When one spring breaks its twin is near the end of the same cycle life. Replacing both prevents a second failure and repeat call-out, and keeps the door balanced.
- 3
Upgrade option
We offer high-cycle springs rated for roughly double the lifespan — worth it on heavy custom doors or homes that cycle the door many times a day.
- 4
Balance & safety test
We wind to the correct tension, confirm the door holds at mid-travel, re-check the safety cables, and verify smooth, quiet operation.
