There's a reason broken garage door springs are among the most frequent service calls across Long Beach. When a spring snaps. and it usually happens without much warning. your door goes from fully functional to completely inoperable in a split second. If your car is inside, you're not going anywhere until it gets fixed.
This post explains how garage door springs actually work, how long they typically last in Long Beach's coastal environment, what the warning signs are, and what you should (and shouldn't) do when one fails.
Your garage door weighs anywhere from 130 to 400 pounds depending on its size and material. Springs are what make lifting that weight feel effortless. they counterbalance the load so your opener motor (or your own arm) isn't doing all the work.
There are two main types:
Torsion springs are mounted horizontally above the door opening on a metal shaft. When the door closes, the spring winds up and stores energy. When you open the door, it unwinds and releases that stored energy to help lift the door. They provide smooth, controlled operation and are the most common type on modern homes. including the many Spanish Colonial Revival and Craftsman bungalows you'll find throughout neighborhoods like Bixby Knolls and Belmont Heights.
Extension springs run along the sides of the door, parallel to the horizontal tracks. They stretch when the door closes and contract when it opens. These are more common on older homes and lighter doors, and tend to be noisier than torsion springs.
Torsion springs generally last longer. around 15,000 to 20,000 cycles, or roughly 7 to 10 years with average use. Extension springs typically see out 5,000 to 10,000 cycles, or about 3 to 5 years. In Long Beach's coastal environment, those numbers can shrink if the springs aren't properly maintained, because salt air accelerates the rusting process on standard steel.
Long Beach homeowners deal with a combination of factors that are harder on garage door springs than what you'd find in an inland city. The city's south-facing coastline means the marine layer and its salt-laden air settle in regularly. especially during spring and early summer when humidity peaks. Salt particles cling to metal springs and draw in moisture, accelerating the oxidation process. This makes standard steel brittle over time, sometimes leading to sudden snaps well before the 10-year mark.
For homes in neighborhoods like Naples Island or along the beachfront in Belmont Shore, this is a real and recurring issue. If your current springs are standard oil-tempered steel, it's worth asking a technician whether galvanized springs. which are coated to resist rust and corrosion. would be a better fit for your location. They hold up significantly better against the salty marine layer that rolls in off the Pacific.
Here's a quick balance test you can do yourself: disconnect the opener and lift the door manually to about waist height, then let go. A properly balanced door (with healthy springs) will stay roughly in place. If it falls quickly or shoots up, the spring tension is off and you need a professional to look at it.
Springs rarely fail completely out of nowhere. there are usually signals in the days or weeks before a break. Learning to recognize these early warning signs can save you from being stranded:
- A loud bang or pop from the garage, even when you haven't operated the door. this is often the sound of a torsion spring snapping - The door feels unusually heavy when lifted manually. springs should make this easy - Visible gaps in the spring coil. a gap in the coil means the spring has given out and can no longer hold adequate tension - The door opens unevenly or one side seems lower than the other - Squeaking, grinding, or scraping sounds that weren't there before. often caused by a spring that's losing lubrication or developing rust - Rust or visible corrosion on the spring coils themselves
If you notice any of these signs, stop using the door and contact a technician before the situation gets worse. Continuing to operate a garage door with failing springs puts extra strain on the opener motor and can damage other components.
This is important: do not attempt to replace or adjust garage door springs yourself. This isn't like changing a light bulb. Springs are under extreme tension. enough to cause serious injury or even death if mishandled. The tools required are specialized, and even small errors during installation can cause immediate failure or a reduced lifespan.
The same applies to adjusting spring tension. If your door feels off-balance, the right move is to call a pro, not to try tightening the spring yourself.
A qualified technician will assess whether you need torsion or extension springs, match the spring to your door's weight and size, and replace both springs at the same time. even if only one has failed. This last point matters: if one spring has worn out, the other is likely close behind. Replacing both at once saves you a second service call within a year or two.
For Long Beach homes near the water, a good technician will also recommend galvanized or coated springs rated for high-salinity environments. These cost a bit more upfront but last considerably longer than standard springs in coastal conditions. Visit our services page for details on what a full spring replacement service includes.
Also worth considering: if your door's springs are failing, it's a good time to have the opener and smart features evaluated too. Our post on smart garage door openers covers what's available and what actually makes a difference for Long Beach homeowners.
How do I know if my garage door spring is broken versus something else? The most telling sign is a loud bang followed by the door refusing to open (or opening only a few inches before stopping). If you look above the door and see a gap in the torsion spring coil, that confirms a break. Another clue: if you disconnect the opener and try to lift the door manually, it will feel extremely heavy. sometimes impossible to lift. when the spring is gone.
Should I replace both springs at the same time, even if only one broke? Yes, and here's the practical reason: both springs were installed at the same time and have gone through the same number of cycles. If one has worn out, the other is usually close. Replacing both at once means you only pay one service call, and you won't be dealing with another broken spring a few months later.
Can California's SB-969 battery backup law affect my spring replacement? SB-969 requires that all residential garage door openers sold or installed after July 1, 2019 include a battery backup. If you're updating your spring system and your opener is older, it's worth upgrading the opener at the same time so you can open the door during a power outage. important in a city like Long Beach where port-area grid events can occasionally cause disruptions. Failure to comply can result in fines, so it's worth getting right.
