Short answer: A broken spring is the single most common reason a garage door suddenly quits working, and it's also the repair where homeowners see the widest spread in quotes. Here is an honest breakdown of what you're actually paying for, and why two "spring jobs" can be priced hundreds of dollars apart.

Why one spring quote can be double another
Most residential doors use either a torsion spring mounted on a shaft above the opening or a pair of extension springs running along the horizontal tracks. Torsion systems generally cost more to service because the parts are heavier-duty and the winding work has to be precise, while extension springs are usually cheaper up front but tend to wear faster. Price also climbs with door size and weight, since a heavy insulated double door needs stronger springs than a light single-car door. Spring quality matters too: a standard spring is typically rated for roughly 10,000 open-and-close cycles, while a high-cycle spring built for 20,000 to 30,000-plus costs more but lasts far longer. As a rough industry range, a single torsion spring replacement often runs about $200 to $350 installed depending on the door, with double-door or high-cycle work landing higher; the spring part by itself is usually only $30 to $100, which means most of the bill is skilled, higher-risk labor rather than the metal.
What a fair quote includes, and the red flags
A straightforward spring job should cover the new spring or springs, the labor to wind and balance the door safely, and a quick check of the cables, bearings, and rollers that work alongside it. On a two-spring door, most reputable techs recommend replacing both springs at once, because if one has failed after years of identical use the second is close behind, and doing both in a single visit avoids a second trip charge later. Be cautious if a conversation jumps from "your spring broke" straight to "you need a whole new door and opener" without a clear reason, since a snapped spring rarely means the door itself is finished. Vague pricing, a refusal to separate parts from labor, or pressure to commit on the spot are all fair reasons to pause and get a second opinion.
Getting the most life out of your next spring
Springs fail from two things: accumulated cycles and corrosion. In a bayside city like Foster City, the damp, salt-tinged air can speed up rust on bare metal hardware, so wiping the springs down and applying a light garage-door lubricant a couple of times a year helps slow that corrosion and keeps the coils moving cleanly. If your door gets heavy daily use, with several trips in and out a day, it can be worth asking about high-cycle springs when you replace, since the modest premium buys years of extra service. Keeping the door balanced helps as well: if you notice it feeling heavier, slamming down at the end, or making the opener strain, having the balance checked early can keep a spring from being overworked into a premature break.
