A broken garage door spring is one of the most common — and most urgent — repairs San Francisco homeowners face. If yours just went, here’s a straight answer on what it usually costs and what actually drives the price. (Every door is different, so treat these as ranges, not quotes — we’ll always give you a firm number before any work.)
Typical ranges in San Francisco
Most residential spring replacements in the city fall in the low-to-mid hundreds of dollars, parts and labor included. The spread depends on the factors below. Doors that need two springs (most double-car doors) cost more than a single-spring door, and it’s almost always worth replacing springs in pairs — if one failed from age and corrosion, the other isn’t far behind.
What drives the price
- Torsion vs. extension springs. Torsion springs (above the door) generally cost a bit more than extension springs (along the tracks) but last longer.
- Spring cycle rating. Higher-cycle springs cost more up front but last far longer — important in San Francisco, where salt air shortens spring life.
- One spring or two. Replacing the pair costs more now but saves a second service call soon.
- Door size and weight. Heavier custom and solid-wood doors need heavier-duty springs.
- Coastal-grade hardware. Galvanized or coated springs resist corrosion better near the ocean — a smart upgrade in the Sunset and Richmond.
Why you shouldn’t DIY it
Garage door springs store a tremendous amount of energy. A spring that lets go during an amateur repair can cause serious injury. The cost of professional replacement is largely about doing it safely and correctly — with the right spring sized to your door, properly wound and balanced.
