There's a particular sound a broken garage door spring makes. a loud bang, like something heavy falling in the garage. that tends to stop homeowners in their tracks. If you've heard it, you know exactly what it means: the car is stuck, the door won't budge, and you've got a repair call to make. If you haven't heard it yet, this post is worth reading before you do.
Spring failures are one of the most common garage door repair calls we see across Eugene and the surrounding communities, including Springfield. And while the repair itself should always be handled by a professional, understanding how springs work. and why they fail faster in our climate. puts you in a much better position as a homeowner.
Your garage door is heavy. A typical two-car door weighs between 130 and 200 pounds, and the opener motor alone isn't strong enough to lift it safely. Torsion springs. the horizontal metal coils mounted above the door. store and release mechanical energy to counterbalance that weight. Without them, the opener would burn out quickly, and the door would be nearly impossible to lift manually.
Most residential doors use one or two torsion springs rated for a specific number of cycles, with one cycle being one full open-and-close. Standard springs are rated for around 10,000 cycles. If you use your garage door four times a day, that works out to roughly seven years of life under normal conditions. Eugene's conditions, however, are not always normal.
Eugene's climate. cool, wet winters and dry summers. puts extra stress on metal components in ways that aren't obvious at first glance. The freeze-thaw cycle that happens on cold nights, when temperatures can drop to around 34°F before climbing back up during the day, causes metal to contract and expand repeatedly. This thermal cycling creates micro-fatigue in spring coils over time.
More significantly, Eugene's persistent moisture accelerates rust. Garage door springs can rust when exposed to moisture, and rust degrades the spring over time, making failure more likely. and less predictable. A spring that's visibly rusty on the outside has likely been corroding from the inside as well. In neighborhoods like South Hills, where many homes were built between 1940 and 1969, it's not uncommon to find springs that are decades old and well past their rated cycle count.
Cold weather adds another layer: when temperatures drop, lubricant thickens and metal contracts, making springs work harder during each cycle. This is why spring failures in Eugene tend to cluster in late fall and winter. the most inconvenient possible time.
Springs rarely fail without some warning. The problem is that the warning signs are easy to dismiss as normal wear. Here's what to pay attention to:
- The door feels heavier than usual when you lift it manually (disconnect the opener by pulling the red release cord and try lifting by hand) - The door opens unevenly, with one side rising faster than the other - You hear squeaking, grinding, or popping during operation that wasn't there before - The door closes too fast, slamming shut instead of lowering smoothly - Visible rust or gaps in the spring coils. a gap in the coil means the spring has already broken
For a broader look at what to watch for, our guide on recognizing garage door warning signs covers springs alongside other common issues.
This part is straightforward: don't try to fix it yourself. Garage door springs operate under hundreds of pounds of tension. An improperly released or installed spring can cause serious injury. This isn't the kind of caution language that gets added to everything. spring-related injuries are genuinely common when homeowners attempt DIY repairs.
What you *can* do safely: - Disconnect the opener and keep the door closed until a technician arrives, Don't try to force the door open manually if the spring has broken. the door is unbalanced and unpredictable, Take note of whether you have one spring or two above the door (two-spring systems are more common on heavier doors)
Garage Door Eugene handles spring replacements regularly across the area. If you're ready to schedule or just want to ask a question first, the contact page is the fastest way to reach us.
For most standard residential spring replacements in the Eugene area, expect to pay between $150 and $350, with the average around $250 including parts and labor. Two-spring replacements cost more, but most professionals recommend replacing both springs at the same time even if only one has failed. the second is usually at a similar point in its life cycle and will likely break within months.
Panel replacements, if needed alongside spring work, run higher. around $500 or more depending on the door style. The difference in cost between a spring replacement and a panel replacement is a good argument for not forcing a door with a broken spring.
You can't stop springs from wearing out, but you can slow the process:
Lubricate the springs twice a year. Use a lithium-based or silicone-based lubricant. apply a light coat to the full length of the coils each fall and spring. This reduces friction and, more importantly in Eugene's climate, creates a moisture barrier that slows rust formation. Wipe the springs down first to remove any existing rust dust before applying.
Keep the garage interior dry. Moisture-laden air from wet vehicles, rain tracked in from outside, and general humidity all accelerate corrosion. A functional bottom weatherstrip keeps pooling water out, and good airflow helps moisture escape. If your garage tends to stay damp through winter, a small dehumidifier can make a meaningful difference.
Test door balance once a year. The balance test. lifting the door manually to the halfway point and letting go. takes about 30 seconds and can tell you a lot. A door that holds position is properly balanced; one that drifts down has spring tension loss that will only worsen. Catching it early means a simpler adjustment rather than a full replacement.

Q: My garage door opener is running but the door won't open. Could it be the spring? A: Almost certainly yes. When a spring breaks, the opener motor runs but can't lift the door's full unbalanced weight. You may hear the motor straining or see the trolley moving without the door following. Stop running the opener. continued use can damage the motor. and call for spring replacement.
Q: Should I replace one spring or both at the same time? A: Both, in almost every case. If your door has two springs and one breaks, the other is typically at a similar age and wear level. Replacing only the broken one means you'll likely be making the same repair call within a year. Most technicians will recommend replacing both, and the added cost is modest compared to a second service call.
Q: How do I know what type of spring system I have? A: Look above the door when it's closed. Torsion springs run horizontally along a metal rod above the door opening. you'll see one or two coiled springs. Extension springs run along the horizontal tracks on either side of the door and stretch when the door closes. Torsion systems are more common on newer and heavier doors; extension springs are often found on older homes. Either way, the replacement process requires a professional.
