If you've ever heard a loud bang come from your garage on a quiet Duarte morning, there's a good chance it was a garage door spring letting go. It's one of the most common calls we get here in the San Gabriel Valley. and one of the most misunderstood repairs a homeowner faces. Before we get into the specifics, let's talk about why springs wear out faster here than in some other parts of the country, and what you can actually do about it.
Duarte sits at the foot of the San Gabriel Mountains and has what climatologists classify as a warm Mediterranean climate. meaning hot, arid summers and cool, wet winters. Temperatures routinely reach the low 90s in summer, and winter nights can dip into the mid-40s. That swing matters more than most people realize.
Temperature extremes are a direct enemy of garage door springs. In extreme heat, the metal in springs expands and can lose tension, affecting door balance. When temperatures drop in winter, metal contracts and becomes more brittle. These repeated cycles accelerate metal fatigue over time, shortening the life of your hardware noticeably.
On top of the daily temperature swings, Duarte and the broader San Gabriel Valley region are no strangers to Santa Ana wind events. These powerful, dry winds blow down through the mountain passes and can easily exceed 40,60 mph, with gusts occasionally surpassing 70 mph. The force placed on a closed garage door during a wind event. what engineers call wind load. creates stress on springs, cables, and the entire door system. If your door is older or already showing wear, a strong Santa Ana can be the thing that pushes it over the edge.
Most standard residential garage door springs are rated for about 10,000 cycles. One cycle equals one full open-and-close of your door. If your household uses the garage door four times a day. a conservative number for most Duarte families who use it as a primary entrance. you're looking at roughly 7 to 10 years of service life before replacement becomes necessary.
There are two main spring types you'll encounter:
Mounted horizontally above the door opening, torsion springs store energy by winding and unwinding as the door moves. They last longer, distribute stress more evenly, and are generally safer when they do eventually fail. Most newer homes and two-car garages use them.
These run along the sides of the door tracks and physically stretch and contract with each cycle. They're more common in older, single-car garages. including many of the classic ranch-style and bungalow homes you'll find throughout Duarte's established neighborhoods. Extension springs tend to wear out faster and carry a higher safety risk when they snap, so upgrading to torsion springs during a replacement is often worth discussing with your technician.
If your home was built in the 1960s or 1970s. very common in Duarte. there's a reasonable chance your springs have never been replaced. That's a safety conversation worth having sooner rather than later. Check out our post on warning signs your garage door needs professional repair if you're unsure whether you're already past due.
Don't wait for that loud bang. Here are the practical signs to watch for:
- The door feels unusually heavy when you lift it manually. Springs counterbalance the door's weight, so when they weaken, you feel it. - One side rises faster than the other. Uneven tension in extension springs causes the door to tilt as it travels. - A visible gap in the spring coil. A separated coil means the spring has already broken. stop using the door immediately. - Squeaking, grinding, or popping sounds during operation, especially when temperatures have been extreme. - The door slams shut faster than normal. Weak springs can't provide enough resistance to control the descent.
If you notice any of these, contact our team before the problem gets worse. A broken spring under tension can release a sudden, serious force. this is not a DIY repair.
This is practical advice that saves homeowners money in the long run: when one spring breaks, replace both. If one spring has accumulated enough stress to fail, the other is typically close behind. Replacing them together means you only pay for one service visit instead of two, and you avoid the inconvenience of a second breakdown just a few months down the road.
For households that use the garage as a primary entry. which is most of Duarte, given the car-dependent layout of the city. upgrading to high-cycle springs rated for 25,000+ cycles is a smart investment. The upfront cost is higher, but the cost-per-year is significantly lower, and you'll go much longer between replacements.
A professional spring replacement typically takes one to two hours. A good technician won't just swap the springs. they'll also check cable condition, test the door's balance, inspect the opener, and lubricate the moving parts. If you haven't had a full inspection done recently, this is a great opportunity to get a complete picture of your door's health. You can learn more about what a thorough checkup should cover on our services page.
For ongoing care between service visits, applying a silicone-based lubricant to your springs every six months goes a long way toward reducing friction and extending their life. especially during Duarte's dry fall and winter months when the lack of humidity can dry out metal components faster.
Q: Can I replace my own garage door springs to save money? A: We strongly advise against it. Garage door springs store an enormous amount of tension. a professional technician handles 100,200 pounds of stored force during a replacement. Without the right tools and training, mishandling a spring can cause serious injury or damage to your door system. The cost of professional replacement is well worth the safety guarantee.
Q: My door still opens. do I really need to replace the spring now? A: If the spring is visibly damaged, gapped, or your door is behaving unevenly, continuing to use it puts extra strain on your opener motor and cables. Catching it early prevents a chain reaction of repairs. A door that still opens with a weakened spring is already doing damage elsewhere in the system.
Q: How do I know if I have torsion or extension springs? A: Look above the door when it's closed. If you see a single metal spring mounted horizontally on a metal rod above the door opening, that's a torsion spring. If you see springs running horizontally along the tracks on the sides of the door, those are extension springs. Still not sure? Our FAQ page covers this and other common garage door questions.
