It usually happens the same way: you hit the button to open the garage, the opener hums, but the door barely moves. or doesn't move at all. You walk over and try to lift it manually, and it feels like it weighs a thousand pounds. That's a broken spring. It's one of the most common garage door problems we see across Santa Monica, and it's one that genuinely cannot wait.
Here's everything you need to know about what happens next.
Your garage door. whether it's a single panel on a Sunset Park bungalow or a wide double door on a newer build north of Montana. is heavier than most people realize. A standard single-car door weighs between 130 and 160 pounds. A double door can push 200 pounds or more.
The springs are what make that weight manageable. They store mechanical energy as the door closes and release it to assist the opener (or your arms) when the door opens. Without a functioning spring, the opener motor is essentially being asked to lift the full dead weight of the door. which is why most modern openers are designed to stop rather than burn themselves out trying.
There are two types of springs you'll encounter:
- Torsion springs mount horizontally above the door opening and work by twisting around a metal shaft. They're more common on heavier sectional doors and are generally considered safer and longer-lasting. - Extension springs run along the sides of the door above the horizontal tracks and work by stretching. They're often found on older or lighter doors.
Most Santa Monica homes built or remodeled in the last two decades have torsion spring systems. If you're in an older Craftsman bungalow in Ocean Park or a mid-century home in the Pico neighborhood, you may have extension springs. worth confirming before scheduling a repair so the technician shows up with the right parts.
Spring lifespan is measured in cycles. one cycle equals one open and one close. Standard residential torsion springs are typically rated for 10,000 cycles. If you use your garage door four times a day (which is common in a household with two drivers), that works out to roughly seven years.
In Santa Monica, that timeline is often compressed. The salt air off the Pacific accelerates oxidation on the spring coils, weakening the metal faster than normal wear alone would. It's not unusual for us to see spring failures on five- or six-year-old doors in beachside areas. This is especially true for homes close to the water. the closer you are to the ocean, the harder the environment is on exposed metal components.
If you want to extend spring life, regular lubrication and a yearly inspection go a long way. Our professional maintenance tips outline exactly what that routine should look like for coastal homeowners.
This is the question most homeowners ask first, and it's a fair one. Nationally, torsion spring replacement runs between $150 and $350 for a single-door system, while extension spring replacement generally falls between $120 and $200. In the Los Angeles metro area. which includes Santa Monica, Venice, and Culver City. costs tend to run toward the higher end of those ranges due to local labor rates.
A few things that affect your total:
Spring type and count. Torsion springs cost more than extension springs, but they last longer. Many single-door systems use one torsion spring; two-car doors often use two.
Replacing both at once. If one spring breaks, the other is close behind. they wear at the same rate. Replacing both during the same service call is almost always more cost-effective than paying for two separate visits. It also keeps your door balanced, which protects the opener and panels from uneven stress.
Hardware upgrades. If you're replacing springs on a coastal home, it's worth asking specifically about galvanized or powder-coated springs rated for salt-air environments. The upfront cost difference is modest; the difference in longevity is significant.
Additional repairs discovered during the job. A broken spring often reveals other worn components. frayed cables, worn rollers, loose track hardware. A good technician will flag these during the service call. Whether you address them all at once or prioritize is up to you, but it's helpful to know going in.
For a straightforward single-door torsion spring replacement in Santa Monica, budget somewhere in the $200,$400 range including labor. Contact us for an accurate quote based on your specific door. we'll give you a written estimate before any work begins.
Garage door spring replacement is one of the few home repairs where the safety case for hiring a professional is essentially non-negotiable. Torsion springs are wound under several hundred pounds of mechanical tension. An improperly handled spring can snap, recoil, or spin with enough force to cause serious injury.
This isn't a liability disclaimer. it's a practical reality. The tools required to safely wind and tension a torsion spring (specifically, winding bars of the correct length and a torque specification matched to your door's weight) are not standard homeowner equipment, and improvising with the wrong tools is genuinely dangerous.
Extension springs carry a different but equally real hazard: when they break under load, they can snap across the garage with significant force. This is why extension spring systems should always include safety cables threaded through the spring. if your system doesn't have these, it's worth having them added during your next service call. See our garage door safety overview for more on what properly configured spring systems should include.
A spring replacement visit from Garage Door Santa Monica typically takes 45 minutes to an hour and a half, depending on the system and whether additional hardware needs attention. Here's the general flow:
1. The technician confirms which spring type and size your door requires, based on door weight and height measurements. 2. The old spring (or springs) is safely removed. 3. New springs are installed and properly tensioned. 4. The door balance is tested. this involves disconnecting the opener and checking whether the door holds in the half-open position under its own weight. A properly balanced door should stay put. 5. The opener reconnects and cycles are run to confirm smooth, even operation. 6. Any additional issues flagged during the inspection are reviewed with you before any further work is done.
If you've been noticing warning signs before the spring fully failed. unusual noise, sluggish movement, a door that feels heavier than usual. those are worth mentioning when you schedule. They help the technician know what else to look for. You can also review our post on warning signs your garage door needs repair to understand what to watch for between service visits.
Once the repair is complete, ask about the spring warranty. Quality springs from reputable manufacturers typically come with a warranty of one to two years on parts. Labor warranty terms vary by company. confirm before the job starts.
Q: My door still opens a little after the spring broke. Can I keep using it until I get it repaired? A: We'd strongly recommend against it. When a spring fails, the opener is carrying the full weight of the door rather than the fraction it's designed for. Continuing to run the opener this way can burn out the motor or strip the gears. turning a $250 spring replacement into a $400+ opener repair on top of it. Leave the door in the down position and schedule a repair promptly.
Q: How do I know if I have torsion or extension springs? A: Stand inside your garage and look at the door hardware. If you see a horizontal metal bar running across the top of the door opening with a spring (or two) coiled around it, those are torsion springs. If you see springs running along the horizontal tracks on each side of the door. stretching lengthwise. those are extension springs. Still not sure? Take a photo and send it to us through our FAQ page or give us a call.
Q: Is it worth upgrading to higher-cycle springs when I replace them? A: For Santa Monica homeowners, yes. generally it is. Standard residential springs are rated around 10,000 cycles. Higher-cycle springs (20,000,30,000 cycles) cost somewhat more but last significantly longer, especially when combined with regular lubrication and the coastal conditions here accelerating normal wear. Over the life of your home, the math tends to favor the upgrade. Ask your technician to walk you through the cost difference for your specific door.
