In our years serving San Marino, we've seen this problem again and again: a homeowner's garage door suddenly stops working, they panic, and they assume the worst. Most of the time, it's a snapped spring. The good news? It's fixable, predictable, and far cheaper than many people fear. This guide breaks down what garage door springs actually cost, when they fail, and how to avoid overpaying.
Your garage door weighs 300 to 500 pounds. It doesn't feel heavy when it opens because two metal springs do nearly all the work. There are two main types: torsion springs (wound around a metal rod above the door) and extension springs (attached to cables on either side). Both stretch and compress thousands of times per year. Over time, metal fatigues. Springs last roughly 7 to 9 years with normal use, though heavy use or poor maintenance can shorten that window significantly. See our guide on emergency garage door repair in san marino: what to do when things go wrong.
When a spring snaps, your door won't open or close smoothly. You might hear a loud bang. Don't ignore it. A broken spring puts extra stress on your garage door opener and can damage the entire mechanism. More importantly, a heavy door with no spring support is a safety hazard.
Spring problems usually fall into three categories: wear and tear, rust, and impact damage. San Marino's mild climate actually works in your favor compared to inland areas that endure extreme temperature swings. But salt air from the coast can accelerate rust on uncoated springs, especially if your garage faces south or west and gets intense sun exposure. Read about matching your garage door to san marino.
A snapped spring typically announces itself loudly. You'll hear a crack or pop, then your door feels impossibly heavy or won't budge at all. Extension springs sometimes break quietly, but the door will still feel off. Torsion springs fail more predictably because the metal is under constant tension.
The longer you wait after a spring breaks, the more damage spreads to your opener and cables. We recommend calling for an estimate within 24 hours of noticing a problem.
Most homeowners in San Marino pay between $200 and $400 to replace one spring, including labor. The spring itself costs $50 to $150 depending on type and size. Labor typically runs $150 to $250 for a skilled technician who can do it safely and correctly.
If both springs fail simultaneously (which happens sometimes), expect $400 to $600 total. That's still far less than replacing an entire garage door or dealing with a damaged opener.
Several factors influence your final cost. Torsion springs usually cost more to replace than extension springs because installation requires specialized tools and training. Larger doors need stronger springs and cost more. Rust or corrosion on the rod adds complexity. If your springs failed due to poor maintenance, addressing underlying issues (like a worn cable or misaligned door) might add $100 to $200 to your estimate.

First, don't attempt this yourself. Springs are under extreme tension. A slip can cause serious injury or death. Hire a licensed professional who carries liability insurance.
Second, get an estimate before committing. A reputable company will inspect your door, identify whether it's one or both springs, check for secondary damage, and give you a clear price. We offer free estimates and can often schedule same-day service if you call early in the day.
Third, maintain your door regularly. Annual lubrication of springs, cables, and tracks reduces rust and wear. Check our garage door maintenance guide for a budget-friendly tune-up routine that can extend spring life by 1 to 2 years.
Fourth, consider preventive replacement if your springs are 8 years old and showing signs of wear (light surface rust, squeaking, slower operation). Replacing both springs at once costs a bit more upfront but saves you from a second emergency call six months later. It's smarter economics than waiting for the second one to snap.
You need immediate help if your door won't open, won't close fully, or feels unusually heavy. You should also schedule service if you hear creaking or groaning sounds or notice visible gaps in the springs. Visit our emergency garage door repair page for details on our rapid response times.

How long do garage door springs last? Most springs last 7 to 9 years with normal residential use, meaning roughly 3 to 5 open/close cycles daily. Heavy use, poor maintenance, or rust exposure shortens this window. Annual lubrication can extend lifespan by 1 to 2 years.
Can I replace just one spring if both are old? You can, but it's not ideal. If both springs are the same age, the second one will likely fail within months. Replacing both at once costs more upfront but saves you a second emergency call and maintains balanced door operation.
What's the difference between torsion and extension springs? Torsion springs wind around a rod above the door and handle the load more efficiently. Extension springs hang on cables beside the door. Torsion springs are safer and last longer but cost slightly more to replace. Most modern doors use torsion.
Is a snapped spring covered by warranty? Manufacturer warranties typically don't cover spring failure because it's wear and tear, not a defect. Some service plans or home warranties may cover parts or labor. Check your policy before assuming you'll pay full price.
Should I replace springs before they break? If your springs are 8 years old, showing surface rust, or making noise, preventive replacement makes financial sense. One emergency call and two separate repairs cost more than replacing both springs proactively.
