If your garage door suddenly felt impossibly heavy this morning, or you heard a loud bang from the garage that rattled the walls, there's a good chance you're dealing with a broken spring. It's one of the most common garage door failures we see here in Moorpark. and also one of the most misunderstood.
Moorpark sits in a valley in southeastern Ventura County, and while the climate is relatively mild compared to places further inland, the combination of warm, dry summers and cool, wet winters does put real stress on metal components over time. Temperatures swinging between the upper 40s on winter nights and the mid-80s on summer afternoons cause metal springs to expand and contract repeatedly. a process that, cycle after cycle, accelerates wear. Add in the Santa Ana wind events that push through the Conejo Valley and into Moorpark, and you've got a climate that's harder on garage hardware than most homeowners realize.
Your garage door. whether it's a standard single-car or the wide two-car doors common in Moorpark's Peach Hill and Mountain Meadows neighborhoods. can weigh anywhere from 150 to 400 pounds. The springs are what make lifting that weight feel effortless. They store mechanical energy when the door closes and release it to counterbalance the door's weight when opening.
There are two main types:
- Torsion springs mount horizontally above the door opening and coil around a metal rod. Most modern garage doors use these because they offer better balance, durability, and a safer failure mode. - Extension springs run along the sides of the tracks and stretch as the door lowers. They're older technology and more common on budget or older doors.
If your home is one of the many built in Moorpark after 1980. which accounts for over 75 percent of the city's housing stock. your door likely uses a torsion spring system.
Don't wait for a full failure. Catch the problem early with these signs:
If the opener runs but the door barely moves. or shoots up unevenly. the spring may have lost tension or snapped entirely. A door that crashes down when you release it manually is also a dead giveaway.
A broken torsion spring releases all its stored energy at once. That sharp crack sounds like something fell off a shelf. If you heard it from inside the house and the door stopped working right after, the spring almost certainly snapped.
Look at the spring above your door. A broken torsion spring will show a clear separation in the coil. a gap where the metal has snapped apart.
If you disconnect the opener and try to lift the door manually, it should feel manageable (around 8,10 pounds of resistance for a balanced system). If it feels like you're lifting a car hood, the spring isn't doing its job.
One broken spring in a dual-spring setup causes uneven lifting. The door tilts to one side and the opener strains to compensate. which can damage the opener motor over time.

Here's an honest breakdown of what you can expect to pay for spring replacement in the Moorpark area:
- Torsion spring replacement: $150,$350 for a single spring, parts and labor included - Dual-spring replacement (both springs): Often $200,$500, depending on spring size and door weight - Extension spring replacement: Generally less expensive, starting around $100,$200 per spring - Converting from extension to torsion: $400,$800. a bigger upfront cost, but torsion systems are safer and last longer
A few things will push your cost higher: emergency or after-hours service, larger or heavier doors (common in Moorpark's newer custom homes near the Country Club area), and if your cables or rollers are worn and need replacing at the same time.
One practical tip: if one spring breaks, replace both. When one fails, the other is usually close behind. Replacing them together during the same service visit saves you a second labor charge and keeps your door balanced.
For most Moorpark homes, torsion springs are the right call. They're rated for 10,000,20,000 cycles, which works out to roughly 7,14 years of typical daily use. They stay contained on the shaft when they break, rather than flying across the garage. And they provide a smoother, more balanced lift that's easier on your opener motor.
Extension springs cost less upfront, but they have a shorter lifespan and a less safe failure mode. If your older home in central Moorpark still has extension springs, it's worth asking about converting to torsion when you schedule your next service.
This one is straightforward: torsion springs are under enormous tension. A fully wound spring stores enough energy to cause severe injury or property damage if it releases suddenly. This isn't a scare tactic. it's physics. The repair requires specialized winding bars, precise tensioning matched to your door's exact weight, and experience knowing what can go wrong.
Garage Door Moorpark's technicians handle spring replacements regularly and have the right tools and training to do the job safely. If you're ready to get this sorted, schedule your service appointment today. most spring replacements can be completed same-day.
Once your springs are replaced, a little maintenance goes a long way:
- Lubricate springs every 3,6 months with a silicone-based or lithium-grease spray. Avoid WD-40, which attracts dust. - Test the door balance annually by disconnecting the opener and lifting the door to waist height. If it stays put, you're balanced. If it drifts up or falls, call for an adjustment. - Don't skip annual tune-ups. A yearly inspection catches tension issues, cable wear, and roller damage before they become expensive problems.

How long do garage door springs last in Moorpark? Most torsion springs are rated for 10,000,20,000 cycles, which translates to roughly 7,14 years of typical use. Families who use the garage as their main entry point (especially common in Moorpark's suburban neighborhoods) may reach that cycle count in as little as 5,7 years. Regular lubrication and annual inspections help extend spring life.
Can I still use my garage door if a spring is broken? No. and you shouldn't try. With a broken spring, the opener motor has to do all the lifting work on its own, which can burn out the motor. The door is also unstable and can drop suddenly. Disconnect the opener, leave the door in the closed position, and call for service.
Should I replace just the broken spring or both at once? Replace both. When one spring fails, the other has typically gone through the same number of cycles and is near the end of its life too. Replacing both in one visit saves you a second service call fee and ensures your door stays properly balanced.
