Garage Door Springs in Napa: Types, Cost & When to Replace
7 min read
Garage door springs come in two main types: torsion and extension. Torsion springs sit above your door and twist to lift it. Extension springs run along the sides and stretch. Most residential doors in Napa use torsion because they're safer and last longer (typically 7 to 9 years). A snapped spring means your door won't open, your opener strains, and you're stuck. Here's what you need to know before calling for help.
Why Springs Fail
Springs don't just break overnight. They wear out from constant use. Every time you open and close your garage door, the spring cycles. A typical spring handles 10,000 to 15,000 cycles before it gives out. That's roughly 7 to 9 years for most households. Cold weather in the Sonoma County foothills can make springs more brittle, too.
Rust accelerates failure. If your spring looks orange or brown, corrosion is eating away at the metal. Lack of lubrication compounds the problem. Springs that aren't oiled dry out and snap under tension. Poor installation is another culprit. If a technician doesn't balance the tension correctly from day one, one spring carries more load and fails first.
Torsion vs. Extension Springs
Torsion springs are mounted horizontally above the door on a rod. They twist as the door moves. These are the preferred choice because they:
- Last longer than extension springs, Distribute force evenly across the door, Are safer (less whipping action if they break) - Work better on heavier doors
Extension springs hang vertically on each side of the door. They stretch as the door opens. You'll find them on lighter, older doors. They're cheaper upfront but wear faster and are riskier if they snap. A broken extension spring can swing wildly.
If you're unsure which type you have, look above and to the sides of your door. Torsion springs sit in the middle above the opening. Extension springs run along the top corners.

Spring Replacement Cost
Spring replacement typically costs between $200 and $400 in the Napa area, depending on the type and door weight. Torsion springs run higher than extension springs. Labor usually accounts for 60 percent of the bill. A free estimate takes 15 minutes. We'll measure your door, assess the springs, and give you an honest number before we touch anything.
Don't ignore a snapped spring hoping it'll magically fix itself. A broken spring puts extra stress on your garage door opener. The motor works harder, heats up, and burns out faster. You end up replacing a $300 spring and a $500 opener instead of just the spring.
Emergency calls after hours cost more. If you notice a spring issue during business hours, schedule a free quote and avoid the premium pricing. Same-day appointments often open up when you call early.
Why You Shouldn't DIY This
Springs are under extreme tension. A 7-foot-wide door with a 400-pound weight creates roughly 200 pounds of tension per spring. If a spring snaps while you're working near it, it can cause serious injury. The rod can whip. The spring can cut skin or break bones.
We see DIY injuries every month. Home repair sites make spring replacement look simple. It's not. You need the right tools, the right safety equipment, and years of experience reading how tension should feel.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs last 5 to 7 years. Lifespan depends on how often you use your door and whether you maintain lubrication.
Can I replace just one spring? We recommend replacing both springs at the same time, even if only one snapped. Matched springs ensure balanced operation. If one failed from age, the other is likely to follow within months.
Why does my door slam shut? A snapped or severely weakened spring can't support the door's weight. The opener can't control descent. This is a safety hazard and requires immediate professional service.
How much does spring replacement cost near me? In the Napa area, expect $200 to $400 for torsion spring replacement, including labor and parts. Extension springs run $150 to $300. Call 510-214-4761 for a free estimate.
Is spring repair cheaper than replacement? Springs can't be repaired. Once broken or severely rusted, they must be replaced. Attempting a temporary fix risks injury and further damage.
