Most homeowners don't think about their garage door springs until the door stops working. That's understandable. springs are out of sight, they're not something you interact with directly, and when things are working fine, there's no reason to pay attention to them. But on Lummi Island and across Whatcom County, the wet winters and salty air create spring-aging conditions that make it worth knowing what to look for before a failure catches you off guard.
A broken spring isn't just an inconvenience. It can strand your car inside the garage, leave your home unsecured, and in some cases create a genuine safety hazard. The good news is that springs usually give warnings before they snap completely. if you know what to look for.
Your garage door weighs anywhere from 150 to 300 pounds depending on the material and size. Torsion springs. the horizontal coiled springs mounted above the door opening. are what make that weight manageable. They store mechanical energy as the door closes and release it to counterbalance the door's weight when it opens. Without functional springs, your opener motor would be trying to lift that full weight on its own, which it's not designed to do.
Torsion springs are more common in modern installations and tend to be more durable, typically lasting 10,000 to 15,000 cycles. Extension springs. the type that run along the sides of the door above the horizontal tracks. are found in older systems and generally wear out faster, usually lasting 10,000 to 12,000 cycles. If you're in an older home in Ferndale or on Lummi Island that hasn't had the spring system upgraded, extension springs are what you likely have.
At the rate most households use a garage door. four to eight times a day. an average spring system reaches its lifespan in roughly seven to ten years. In a coastal salt-air environment like Lummi Island, that timeline can shorten noticeably.
This is often the first hard sign. Most garage door openers have a built-in safety feature that stops the door from moving if the spring tension is wrong. the opener senses it's working too hard and stops. If your door opens a few inches and then stops, don't keep pressing the button. A broken spring is a likely cause, and forcing the opener to compensate puts strain on the motor.
A spring breaking under full tension can make a sharp, sudden noise. sometimes described as sounding like a gunshot. If you hear this sound from your garage and the door stops working immediately after, a spring has most likely snapped. Stop using the door and call a professional. Attempting to force the door open manually can cause cables to go slack and create additional damage.
Torsion springs should have tightly wound, uniform coils with no breaks in them. If you look up above your door opening and notice a gap of two inches or more in the spring, that spring has snapped. This is the clearest possible indicator that replacement is needed immediately. Don't try to operate the door.
A healthy door moves smoothly and stays level as it opens and closes. If your door rises unevenly. one side higher than the other. or if it moves with a jerky, stuttering motion, one spring may be weaker or already broken. Uneven tension forces the tracks, rollers, and cables to compensate, which leads to additional wear and can eventually cause the door to jump off its tracks entirely. This is one of the more expensive outcomes of deferred spring repair.
Here's a simple test: disconnect the opener by pulling the red emergency release cord, and try to lift the door manually to about waist height. A properly balanced door should feel relatively light and stay in place when you let go. If it feels like you're lifting dead weight, or if it immediately slides back down, the springs are no longer doing their job. This is also how you can catch a problem before the door stops working entirely. which is the ideal scenario.
Springs lose elasticity over time. As that happens, they often announce it with noise. squealing and grinding sounds are common as springs wear down. In the wet winters on Lummi Island and across the Bellingham area, moisture accelerates this process. If your door has started sounding noticeably different than it did six months ago, that's a reasonable trigger to schedule an inspection rather than waiting for something to break. You can check our FAQ page for more on what a standard spring inspection involves.
This comes up a lot, and the answer is straightforward: springs store an enormous amount of mechanical energy. A torsion spring under full tension can cause serious injury if it releases unexpectedly. broken bones, facial injuries, and worse have resulted from amateur attempts at replacement. Proper installation requires specialized winding bars and training. It's one of the few home repairs where the risk genuinely isn't worth the savings. Understanding the true cost of repair versus replacement is covered in more detail in our repair cost breakdown guide.
When one spring fails, it's worth replacing both at the same time. even if only one looks damaged. If one has reached failure, the other has experienced similar wear and is likely close behind. Replacing both together saves a second service call and ensures the door operates evenly.
The combination of Lummi Island's high humidity. often above 80 percent during our wet season. and salt air exposure means springs here accumulate surface rust faster than springs on mainland properties in Lynden or Everson. Rust on a spring isn't just cosmetic; it accelerates the structural weakening of the metal and can cause a spring that's only a few years old to behave like one that's well past its service life.
A quick visual inspection every couple of months takes about 30 seconds. Look for rust streaks, uneven coil spacing, or any visible gaps. It's the easiest preventive maintenance you can do, and catching a failing spring early means a scheduled repair instead of an emergency call.

How do I know if I have torsion or extension springs? Look above the door when it's closed. If you see a single large horizontal coiled spring (or two springs) mounted on a steel bar directly above the door opening, those are torsion springs. If you see springs running horizontally along the tracks on either side of the door, those are extension springs. Torsion systems are more common in homes built or renovated in the last 20 years.
Can I use my garage door if a spring is broken? You can, but you shouldn't. Operating the door with a broken spring puts excessive strain on your opener motor and risks damaging cables, rollers, and tracks. It can also cause the door to drop unexpectedly if the opener gives out under the load. The safest approach is to stop using the door and call for service.
How long does a spring replacement take? For a straightforward torsion spring replacement, most professional technicians can complete the job in 60 to 90 minutes. If there's additional hardware damage or cable issues discovered during the repair, it may take longer. A good technician will give you a clear picture of what's needed before starting work.
