Garage Door Spring Warning Signs Burlingame Homeowners Shouldn't Ignore
2026-04-07 6 min read
Most homeowners in Burlingame don't think much about garage door springs. until the morning the door refuses to open and they're stuck in the driveway with somewhere to be. Springs are the workhorses of your entire door system, and they fail more often than any other component. Knowing what to watch for can save you from a surprise breakdown and, more importantly, a potential safety hazard.
Why Springs Fail in the First Place
Your garage door springs do an enormous amount of work. Every time you open and close your door, the springs cycle through tension and release to counterbalance the full weight of the door. which can be anywhere from 150 to 300 pounds or more. Most standard springs are rated for around 10,000 cycles. If you use your garage door four times a day (not uncommon in a commuter-friendly city like Burlingame, minutes from SFO and Caltrain), that's roughly 1,460 cycles per year. meaning a spring could reach the end of its life in seven to nine years.
Environmental factors speed that timeline up. The Bay-side humidity and salt air that Burlingame and neighboring San Mateo deal with year-round accelerate rust and corrosion on metal coils. Rust doesn't just look bad. it weakens the metal, creates friction in the coils, and causes springs to fail well before their rated cycle count.
This is why springs in coastal Peninsula homes often need attention earlier than the same door in a drier climate. It's not a product quality issue. it's simply where we live. Learn more about what professional maintenance covers and how it can extend spring life.
The Two Types of Springs You'll Find in Burlingame Homes
Burlingame's housing stock runs the gamut from 1920s Craftsman bungalows to mid-century ranches to newer builds, and the garage door hardware reflects that diversity.
Torsion springs are mounted horizontally above the door opening and use torque to lift the door. They're the more modern, durable option and are common on doors installed in the last 20,30 years. They generally last longer and are safer when they fail because the coil stays relatively contained.
Extension springs run along the horizontal tracks on either side of the door. They're more common on older homes and work by stretching as the door lowers and contracting as it rises. If you're in an older home in Burlingame Park or along the Broadway corridor and haven't had your door updated, there's a good chance you have extension springs.
Both types fail, and both require professional replacement. This is not a DIY repair. springs store significant mechanical energy under tension, and improper handling causes serious injuries.
Warning Signs You Shouldn't Dismiss
The good news is that springs usually give you some warning before they fail completely. Here's what to watch for:
The Door Feels Unusually Heavy
Spring systems are designed to counterbalance the door's weight. When they weaken, the full weight of the door shifts to your opener motor. or to you, if you're lifting manually. If your door suddenly feels much heavier than it used to, the springs are likely losing tension.
The Door Won't Stay Open
A properly balanced door should remain at roughly waist height when you stop it midway during opening. If it slowly creeps back down on its own, your spring tension has degraded. A door that drops unexpectedly is a real safety hazard, particularly for children or pets.
You Hear a Loud Bang From the Garage
A torsion spring breaking under tension makes a sharp, sudden noise. often described as sounding like a firecracker or a gunshot going off inside the garage. If you hear this and your door stops functioning, a spring has snapped. Stop using the door immediately and call for service.
Visible Gap in the Spring
Look up at the spring mounted above your door. Torsion springs should have tight, evenly wound coils from end to end. A gap of two inches or more means the spring has broken. Extension springs may look overstretched or appear to be hanging loosely rather than holding tension.
The Opener Strains or Stops Mid-Cycle
Your garage door opener is not built to lift a door's full weight on its own. When springs weaken, the opener compensates. working harder than it was designed to, which burns out the motor over time. If your opener sounds labored, hums longer than usual, or stops before the door is fully open, get the springs inspected before you end up replacing the opener too.
One Side Looks Higher Than the Other
If the door rises unevenly. one side higher than the other, or the door looking slightly tilted. one spring has likely failed while the other is still functioning. This puts uneven stress on your tracks, cables, and rollers. Don't keep operating it this way.
What Happens If You Ignore These Signs
Continuing to use a door with compromised springs puts stress on every other component in the system. Cables go slack and can snap. Tracks can bend from the uneven load. The opener motor burns out. What starts as a spring replacement can turn into a much more expensive repair if you wait. Check our FAQ page for more on what a typical repair visit involves and what to expect.
Garage Door Burlingame handles spring replacements throughout Burlingame and the surrounding Peninsula communities. When one spring goes, it usually makes sense to replace both at the same time. since they were likely installed together, the second spring is typically near the end of its life as well.
Frequently Asked Questions
Can I still open my garage door if a spring is broken? Technically you might be able to, but you shouldn't. A door without a functioning spring is extremely heavy and puts dangerous strain on the opener, cables, and tracks. If a spring has snapped, use your entry door instead until a technician can service the system.
How long do garage door springs last in the Bay Area? Most springs are rated for 10,000 cycles, which works out to roughly seven to ten years of average use. In coastal areas like Burlingame where humidity and salt air accelerate corrosion, springs can wear out faster. Regular lubrication and annual inspections help extend their lifespan.
Should I replace both springs at the same time? Yes, in almost every case. When one spring fails, the other has typically gone through the same number of cycles and is under the same level of wear. Replacing both at once saves you a second service call in the near future and keeps the door operating with balanced tension on both sides.
