If your garage door suddenly refuses to open one morning. or you hear a loud bang from the garage and walk in to find the door dead in its tracks. there's a very good chance a spring has let go. It's one of the most common calls we get here in Benicia, and it almost always comes as a surprise to homeowners. Here's what you need to know.
Most people think the opener lifts the door. It doesn't. not really. The springs do the heavy lifting. A typical residential garage door weighs anywhere from 150 to 300 pounds, and the springs counterbalance that weight so the opener motor only has to move a fraction of that load. When a spring fails, the opener is suddenly trying to muscle a full-weight door on its own. and it usually can't.
There are two main types of springs you'll encounter:
- Torsion springs. mounted horizontally above the door opening on a metal bar. These are the modern standard and are found on most Benicia homes built in the last few decades. They're rated for 10,000 to 20,000 cycles and tend to be safer when they break. - Extension springs. run along the sides of the door, parallel to the horizontal tracks. More common in older homes, lighter-duty doors, and some of Benicia's historic downtown bungalows built before the 1980s. They're less expensive but have a shorter lifespan and can be more hazardous if they snap without a safety cable.
Benicia sits on the north bank of the Carquinez Strait, which means the air here carries real moisture and salt. even when it doesn't feel humid. That salt-laden air is hard on metal components. Garage door springs can rust when exposed to coastal moisture, and rust doesn't just look bad. it actively degrades the spring's structural integrity, causing it to fail well before its rated cycle count.
Benicia's climate is temperate and Mediterranean with rainfall mostly from December through April. That wet season means springs go through repeated thermal and moisture cycles that accelerate wear. If you haven't had your springs inspected or lubricated in a year or two, they may be closer to failure than you realize.
For homeowners in Vallejo and Martinez who live near the water, the same coastal exposure rules apply. this is a regional issue, not just a Benicia one.
Don't wait for the loud bang. Here are the signs to watch for before a spring breaks completely:
- The door feels unusually heavy when you lift it manually. A properly balanced door should feel like roughly 10,15 pounds. If it feels like you're lifting a refrigerator, the springs are losing tension. - The door won't stay open halfway. Lift the door to waist height and let go. it should hold its position. If it drifts down, the springs aren't counterbalancing correctly. - Visible gaps in the torsion spring coils. Healthy coils are tightly wound and touching. If you can see a gap in the coil, that spring is on borrowed time or already broken. - The door drops faster than normal when closing, or closes unevenly. one side lower than the other. - Screeching or popping noises when the door moves. This can indicate a spring under excessive stress or one that's started to corrode. - The opener strains, slows, or stops mid-cycle. When springs weaken, the opener has to work much harder. This burns out motors prematurely. turning a spring problem into a much more expensive opener problem.
If you're seeing any of these, it's worth having a tech look at the system before it becomes an emergency. You can learn more about what your opener symptoms might mean on our services page.
This is the question everyone wants answered, and the honest answer is: it depends on a few factors.
For most Benicia homeowners, torsion spring replacement runs $150,$350 per spring including parts and labor. Extension springs are a bit less. typically $100,$200 per spring. Most single-car doors have one or two springs; double-car doors often use two torsion springs or a pair of extensions.
Here's the important thing: replace both springs at the same time, even if only one is broken. Springs age together. If one has failed, the other is usually close behind. Replacing them as a pair ensures balanced tension and prevents a second service call a few weeks later.
A few factors that can push costs higher in this area:
- Heavier doors (solid wood, insulated steel overlays) require stronger, more expensive springs - Upgrading to high-cycle springs. budget springs are rated for 5,000,10,000 cycles and may last 5,7 years; premium springs can be rated for 25,000,50,000+ cycles and last 15,20 years. In a salt-air environment, investing in quality here is worth it. - Emergency or after-hours service typically adds a fee
For a ballpark, most homeowners pay between $200 and $500 total for a professional spring replacement on a standard residential door. If your door also needs cable work or hardware adjustments at the same time, factor in a bit more.
We'll be straight with you: garage door spring replacement is not a project for a YouTube tutorial and a Sunday afternoon. Torsion springs store an enormous amount of energy. enough to cause severe injury if released suddenly. The U.S. Consumer Product Safety Commission reports roughly 30,000 garage door injuries annually, and spring-related incidents are a significant portion of that number.
A licensed technician uses calibrated winding bars, proper safety equipment, and knows the exact spring specs required for your door's weight. Cutting corners here creates real safety risk and usually results in improper tension, which puts undue strain on your opener and door hardware.

A little preventive care goes a long way, especially given Benicia's coastal conditions:
1. Lubricate springs every 3,6 months with a lithium-based or silicone spray lubricant. Homeowners in coastal areas should do this more frequently than the standard annual schedule. 2. Test door balance annually. Disconnect the opener, lift the door halfway, and release. It should stay put. 3. Schedule a professional tune-up once a year. A technician can spot early signs of wear before a spring fails completely. Our spring preparation tips post covers more on keeping the whole system in shape between service visits.
Q: My garage door opener is running but the door won't open. could it be the spring? A: Very likely, yes. When a torsion spring breaks, the opener motor engages but can't lift the unbalanced weight of the door. You may hear the motor running while the door barely moves or doesn't move at all. Stop running the opener immediately. forcing it against a broken spring can burn out the motor.
Q: Can I still use my garage door with a broken spring? A: Technically you can operate it manually, but it will be extremely heavy and difficult to lift safely. We strongly recommend not using the door until the spring is replaced. Running the automatic opener with a broken spring risks damaging the opener motor and other hardware.
Q: How long does a spring replacement take? A: For a professional technician, a standard spring replacement takes about 45 to 90 minutes, including inspection, installation, balancing, and testing. We come stocked with the most common spring sizes so there's rarely a wait for parts.
