Garage Door Springs in Monrovia: When to Replace, Cost & Same-Day Service
2026-06-19 7 min read
If you've ever dealt with a stuck garage door that won't budge, there's a good chance a snapped spring is the culprit. After 15 years on the trucks in Monrovia and surrounding areas, I can tell you that garage door springs fail more often than homeowners expect, and the cost to replace them varies wildly depending on whether you have a torsion or extension spring system.
Understanding Your Garage Door Spring System
Most homes in Monrovia use one of two spring types. Torsion springs sit above the door on a metal shaft and twist to lift the weight. Extension springs run along the sides and stretch when the door opens. Both do the same job, but they fail differently and cost differently to replace.
Torsion springs last roughly 7 to 9 years with normal use. Extension springs typically go 5 to 7 years. The lifespan depends on how often you open and close the door, whether you maintain the hinges and hardware, and whether the system gets regular lubrication. In Monrovia's heat and sun, springs wear faster than in cooler climates, so don't be shocked if yours needs replacement sooner than the manual suggests.
Why Springs Break and What You'll Notice
Springs don't just fail overnight (though it feels that way). Metal fatigues over time. Each cycle weakens the coil until one day, the spring snaps. When it happens, you'll hear a loud bang from the garage, and your door won't open or close smoothly. Some people try to force the opener, which damages the motor.
Never ignore a snapped spring. A broken spring puts dangerous stress on your garage door opener and can cause the door to fall unexpectedly. If you have kids or pets in the garage, this is a serious safety risk. For more on safe garage door operation, check out our guide to garage door safety in Monrovia.
Garage Door Spring Replacement Cost in Monrovia
Here's what I tell customers when they ask for an estimate. A single torsion spring replacement typically runs between $200 and $400, depending on the spring's size and quality. Most doors have two springs, so budget $400 to $800 for both. Extension springs are slightly cheaper per spring, around $150 to $300 each, but labor is often the same.
Why the range? Premium springs last longer and come with better warranties. Cheap springs might save you $50 upfront but fail in five years instead of eight. We always give customers the full picture, not just the lowest price.

Labor typically adds $100 to $200 per spring, depending on how accessible your springs are and whether we need to remove the door. If your opener motor is old or damaged during the repair, you might need a replacement, which adds to the total cost.

DIY or Professional Service?
I won't sugarcoat this: replacing garage door springs is not a DIY job. Springs are under extreme tension. If you slip with a tool or don't wind them correctly, you can break bones or worse. I've seen too many DIY attempts go sideways. Let a licensed technician handle it.
Our team at Garage Door Monrovia can schedule a same-day visit for most spring replacements. We carry common spring sizes and finish most jobs in under two hours.
Extending Your Spring's Life
Regular maintenance matters. Lubricate your springs twice a year with a silicone-based spray. Keep the garage door tracks clean and aligned. Don't ignore small noises or jerky door movement; those are early warning signs. We offer preventative maintenance plans that catch wear before something breaks. More details are in our garage door maintenance guide for Monrovia homeowners.
When to Replace vs. Repair
If one spring breaks and the other is still healthy, replace just the broken one. If both are showing age (squeaking, slow lift, or uneven movement), replace them both at the same time. Replacing a second spring two months after the first is frustrating and expensive. Think of it like car tires: you can replace one, but matching pairs perform better.
Springs aren't something you can patch. Once they snap, they're done. The only option is replacement.
Monrovia's heat and sun wear springs faster than cooler regions. If you haven't replaced yours in five years or more, it's time to call for an estimate. Don't wait for a failure that leaves you locked out of your garage or, worse, creates a safety hazard.
Spring problems don't fix themselves. Call us at (619) 393-8837 or get a same-day estimate and we'll have you back in business within hours.
Frequently Asked Questions
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use. Extension springs typically last 5 to 7 years. Life span depends on door cycles, maintenance, and climate. Monrovia's heat accelerates wear.
Can I replace one spring or do I need both? You can replace a single broken spring. However, if both springs are old, replace them together. The second one will likely fail soon, and replacing springs twice in a few months costs more than doing both at once.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are more durable and safer. Extension springs stretch along the sides and are cheaper but wear faster. Most newer homes use torsion springs.
How much does spring replacement cost near me? Expect $200 to $400 per torsion spring plus labor of $100 to $200. Extension springs run $150 to $300 each. Total for both springs typically ranges from $400 to $800, plus labor. Call for a free quote.
Is garage door spring repair urgent? Yes. A snapped spring creates a safety hazard and can damage your opener. Don't try to force the door open. Call for same-day service to avoid injury or further damage.
