If you've ever walked into your garage on a rainy January morning only to find the door completely unresponsive, there's a good chance a spring gave out overnight. It's one of the most common service calls we see across Portland. and it's no coincidence that the bulk of them happen between November and February.
Portland's climate is genuinely hard on garage door hardware. We get wet winters with temperatures hovering in the mid-30s to upper-40s, and December alone averages over 4.5 inches of rainfall. That persistent moisture, combined with frequent temperature cycling, accelerates rust and corrosion on metal components far faster than you'd see in drier climates like Bend or Boise. If your springs haven't been inspected in a few years, the Pacific Northwest rain has likely been doing quiet damage.
Your garage door relies on one of two spring systems to counterbalance its weight, which typically runs 150,300 lbs.
Torsion springs mount horizontally above the door opening and wind or unwind as the door moves. They're standard on most Portland-area homes built after 1980 and are generally more durable.
Extension springs run along the horizontal tracks on either side of the door and stretch to lift it. These are common on older homes. and if you live in a Craftsman bungalow in Irvington, Laurelhurst, or Sunnyside, your detached garage likely has extension springs that are original or close to it.
Knowing which type you have matters because they fail differently, require different replacement hardware, and carry different safety risks during repair.
Springs don't usually fail without warning. Here's what to watch for:
- The door feels unusually heavy when you lift it manually. A properly balanced door should stay put when raised to waist height and released. If it drops, the springs aren't doing their job. - A loud bang from the garage, similar to a gunshot, often means a spring has snapped under tension. - The door opens unevenly, sagging on one side. a classic indicator of uneven spring tension or a broken spring on one side. - Visible gaps in a torsion spring coil mean the spring has separated and needs immediate replacement. - Squealing or grinding during operation can signal that springs are losing elasticity and need lubrication or are approaching end of life.
Most torsion springs are rated for 10,000 to 15,000 cycles, where one cycle equals a complete open-and-close. For a typical Portland household opening the garage four times a day, that translates to roughly seven to ten years of service life. If your door is in that range, it's worth having the springs inspected proactively. especially heading into fall when the wet season begins. Our winter maintenance guide covers this and other seasonal prep steps in detail.
We'll be direct here: garage door spring replacement is not a weekend DIY project, no matter how handy you are. Torsion springs store an enormous amount of mechanical energy. releasing that tension incorrectly can propel a spring with enough force to cause serious injury. The Consumer Product Safety Commission tracks dozens of ER visits each year from spring-related accidents.
Beyond the safety risk, an incorrectly wound spring puts the wrong tension on your opener motor, potentially burning it out and turning a $300 spring repair into a much larger bill. It also voids most opener warranties.
Leave this one to a licensed technician. A professional spring replacement typically takes 60 to 90 minutes and usually runs between $200 and $450 depending on door size, spring type, and whether you need a single or double spring replaced.

Yes. and here's the practical reason why. Springs on the same door wear at roughly the same rate. If one has broken, the other is close behind. Replacing both at the same time costs only marginally more than replacing one, but it saves you a second service call within a year or two. Most reputable technicians will recommend this, and it's genuinely good advice.
When you're having springs replaced, it's also a smart time to ask the technician to lubricate the rollers, hinges, and cables, and check the opener's force settings. an unbalanced door puts extra load on the motor every single cycle.
1. Stop using the opener immediately. Running the opener with a broken spring can strip the motor gears. 2. Don't try to lift the door manually without the spring assist. the door is much heavier than it feels with functioning springs. 3. Disconnect the opener using the red emergency release cord and leave the door in the down position. 4. Call a professional to assess the damage before attempting anything else.

How long do garage door springs typically last in Portland? Most torsion springs are rated for 10,000,15,000 cycles. For a household using the garage door four times daily, that's roughly 7,10 years. Portland's moist winters can shorten that lifespan due to rust and corrosion, so annual inspections are worthwhile.
Can I use my garage door if a spring is broken? Technically the opener may still try to operate, but you shouldn't let it. Running the motor without proper spring counterbalance can damage the opener and may cause the door to drop suddenly. Keep the door down and call a technician.
Is it worth upgrading to high-cycle springs when replacing? For most homeowners, yes. High-cycle springs rated for 25,000+ cycles cost somewhat more upfront but significantly extend replacement intervals and often come with better corrosion resistance. a real benefit given how much moisture Portland doors are exposed to year-round.
