Here's a scenario that plays out more often than most Custer homeowners expect: you press the button to open your garage door on a Tuesday morning, the opener hums, and the door barely moves. or doesn't move at all. The culprit, almost every time, is a broken spring.
Garage door springs do the heavy lifting that most people attribute to the opener motor. A typical garage door weighs between 150 and 300 pounds, and the springs counterbalance that weight, making it possible for a relatively small motor (or a single person) to raise and lower it easily. When a spring fails, none of that counterbalance exists.
What makes this frustrating is that spring failure rarely comes out of nowhere. There are almost always warning signs. you just need to know what to look for.
Standard residential garage door springs are rated for roughly 10,000 cycles. For a typical household using the garage as the main entry point, that translates to somewhere around seven to ten years of service life. In drier climates, some springs last even longer.
In Custer and the surrounding Whatcom County area, though, the math isn't as favorable. The combination of persistent moisture, temperatures that hover just above freezing through much of winter, and the expand-contract cycle that comes with our seasonal temperature swings all accelerate metal fatigue. The same wet climate that affects your door panels also affects the springs. rust weakens coil integrity faster than wear alone would. Homes in Blaine and Birch Bay deal with even higher coastal humidity that compounds this further.
Knowing this, it's worth checking your springs at least twice a year and paying attention to how your door sounds and behaves during daily use.
Disconnect your automatic opener by pulling the emergency release cord, then try to lift the door manually. A properly balanced door with functioning springs should feel light. like it's almost lifting itself. If it feels like you're lifting dead weight, the springs have likely lost tension or failed entirely. This is one of the clearest physical tests you can perform.
This isn't a coincidence or an opener glitch. Most garage door openers have a built-in safety feature that detects when the door is too heavy to operate safely. typically triggered by a broken spring. and halts operation after a few inches. If your door repeatedly stops at the same low point, don't keep forcing it.
The torsion spring is the large coiled spring mounted horizontally above your garage door. Take a look at it. it should appear as a continuous, even coil with no breaks. If you see a gap anywhere along its length, the spring has broken and the door should not be used until it's replaced.
If one spring weakens or fails before the other, the door loses balanced support and tilts to one side when opening or closing. You might notice one corner of the door rising faster, or the door appearing to sag on one side when it's in the down position. This uneven loading also puts stress on the cables and opener, compounding the problem if left unaddressed.
A spring under normal operation is nearly silent. Creaking, popping, or snapping sounds during opening or closing indicate that coils are under stress. either from developing micro-fractures or from misalignment due to uneven wear. A sudden loud bang, sometimes described as a gunshot sound coming from the garage, usually means a spring has just broken completely.
This is especially important to check if your garage doesn't have great ventilation or if your door faces a direction that gets a lot of wind-driven rain. Rust on the spring coils isn't just a cosmetic issue. it reduces the spring's tensile strength and increases the likelihood of an unexpected break. Orange or reddish discoloration along the coils warrants a professional inspection.
Your opener motor is sized to move a properly counterbalanced door. When springs weaken, the opener suddenly has to work much harder than it was designed to. If you notice the motor slowing mid-cycle, the door reversing unexpectedly, or the opener running unusually loud, weakening springs may be the root cause. not the opener itself.
The most important thing: stop using the door if you believe a spring has broken. Operating a door with a failed spring puts stress on the cables, the opener, the rollers, and the door panels themselves. What starts as a spring replacement can quickly become a much more expensive repair if those secondary components are damaged.
Garage door springs are under extreme tension. hundreds of pounds of stored force. and replacing them is not a DIY project. Improper handling can cause serious injury. This is a job that requires specialized tools and training, and it's genuinely one of the most safety-critical repairs in home maintenance.
If you're ever locked out of your garage due to a spring failure, our post on manual release mechanisms explains how to safely operate your door by hand in an emergency.
If you've noticed one or more of these warning signs, the right move is to schedule an inspection before the spring fails completely. Proactive replacement is less expensive and far less disruptive than an emergency call when your car is stuck inside.

Can I still use my garage door if I think a spring is weakening but hasn't broken yet? It depends on the severity. If the door is moving and balancing relatively normally but you're hearing unusual sounds or seeing early rust, you can continue using it cautiously while scheduling an inspection soon. But if the door feels heavy to lift manually, is opening unevenly, or you see a visible gap in the torsion spring, stop using it and call a professional. Continuing to use a failing spring system risks damaging the opener, cables, and door panels.
Do both springs need to be replaced at the same time, even if only one is broken? Yes, and this is a recommendation that holds up well in practice. If one spring has worn out, the other has been through the same number of cycles under the same conditions. Replacing only the broken spring leaves you with one new spring and one that could fail within months. Replacing both at once saves you a second service call and ensures your door is balanced and operating safely.
How can I tell if my garage has torsion springs or extension springs? Torsion springs are mounted horizontally on a metal shaft directly above the garage door opening. you'll see one or two large coiled springs centered above the door. Extension springs run along the horizontal tracks on either side of the door, stretching when the door closes and contracting when it opens. Torsion spring systems are more common in newer construction and generally last longer. If you're not sure which system you have, our FAQ page has additional information, or feel free to ask when you call for service.
