If you've lived in Port Townsend through a few winters, you know the pattern: gray skies from November onward, rain that comes in waves off the Strait, cold mornings that don't warm up much by afternoon. It's a climate that feels mild compared to the rest of the country, but it's deceptively hard on mechanical systems. including your garage door springs.
Spring failures in this region aren't random bad luck. There's a real and predictable mechanism at work, and once you understand it, you can take straightforward steps to get ahead of it instead of getting caught on a cold morning with a door that won't budge.
Your torsion spring. the large coiled spring mounted horizontally above your garage door. is under constant tension. Every time the door opens and closes, it twists and unwinds, completing one cycle. Standard springs are typically rated for around 10,000 cycles. For a household using the garage as a primary entry point, that can add up to roughly 7,10 years of life under ideal conditions.
But Port Townsend's winters aren't ideal conditions.
The issue is the combination of repeated freeze-thaw cycling and persistent moisture. Port Townsend's temperatures hover right around freezing on winter nights. dropping overnight, then climbing back into the 40s during the day. Each of those temperature swings causes the metal in your springs to contract and then expand again. Over a full winter, that's dozens of cycles of stress on top of the mechanical cycles from regular door use.
With 180+ days of rain annually and humidity that stays elevated all year, the springs never fully dry out between temperature swings. Moisture penetrates microscopic stress points in the metal and begins corroding from the inside out. By late winter. typically February and March. springs that looked fine in October may have developed invisible internal damage that makes them a serious failure risk.
This is also why spring failures often happen overnight or first thing in the morning, when temperatures are at their lowest and the metal is most contracted and brittle.
Springs don't always break without warning. Here's what to look for:
- A visible gap in the torsion spring coil. a clear separation means it has already broken - The door feels unusually heavy when you disconnect the opener and try to lift it manually. this means spring tension has dropped significantly - Jerky or uneven movement as the door opens. one spring may be weakening faster than the other - Squeaking or grinding sounds when the door operates, especially in the morning. this often indicates stress and rust in the coils - Visible rust patches on the spring coils. surface corrosion often accompanies deeper internal weakening
If you're noticing any of these signs, stop using the door as your primary entry point and get a professional inspection scheduled promptly. Operating a door with a compromised spring puts extra strain on the opener motor and can lead to sudden failure.
Once or twice a year. fall is an ideal time, before the wet season intensifies. do this simple balance test:
1. Disconnect the automatic opener by pulling the red emergency release cord. 2. Manually lift the door to about waist height. 3. Let go and step back.
A properly balanced door will stay roughly in place. maybe drifting very slightly. If it drops quickly to the floor or shoots upward, your spring tension is off and needs professional adjustment. This test takes about two minutes and can tell you a lot about the health of your spring system before a failure happens.
For homeowners in Sequim or Chimacum who use their garages as workshop space and put higher daily cycle counts on their doors, this test is worth doing seasonally rather than annually.
Be direct about this: do not attempt to replace or adjust torsion springs yourself. These components operate under extreme tension. enough to cause serious injury if the spring releases unexpectedly. This is one of those jobs where the savings from DIY are not worth the risk. Professional replacement costs far less than emergency care.
A qualified technician can also assess whether your springs are appropriately rated for your door's weight. Many homes. especially older properties where garages have been retrofitted over the years. have springs that were installed for a different door than what's currently hanging. An undersized spring fails faster and puts more strain on the entire system.

Apply a silicone-based lubricant to the spring coils at the start of each season. not WD-40, which evaporates quickly and can attract dust to the coils. Proper lubrication reduces friction during operation and creates a moisture barrier that slows corrosion. This single step can meaningfully extend spring life in a high-humidity environment. Our post on understanding the real value of routine maintenance breaks down why consistent small investments in upkeep pay off over the life of the system.
If you're replacing springs, ask about high-cycle spring options rated for 25,000 or even 50,000 cycles, with powder-coated or galvanized finishes. In Port Townsend's wet climate, the corrosion-resistant coating matters as much as the higher cycle rating. The cost difference over a standard spring is modest compared to the extended service life in a demanding environment.
Water pooling along the threshold and freezing against the bottom seal is a common winter problem. A compromised bottom seal lets moisture directly into the lower track area, which speeds up corrosion on nearby hardware and can cause the door to freeze to the ground on cold mornings. Inspect and replace the bottom seal before November each year. If your garage tends to collect water on the floor, address the drainage issue too. the FAQ page has information on common garage door moisture problems worth reviewing.
Q: My garage door made a loud bang last night and now won't open. Is that a broken spring?
A: Most likely, yes. A loud bang from the garage. even when the door wasn't in use. is the classic sound of a torsion spring snapping under tension. Look above the door for a visible gap in the coil. Do not try to operate the door with the automatic opener, as this can damage the opener motor. Call a professional for same-day service.
Q: How do I know if my garage door springs are the right size for my door?
A: The easiest way to check is the balance test described above. If the door won't stay at mid-height when manually lifted and released, the springs aren't properly matched or tensioned for your door's weight. A technician can measure your door's actual weight and verify the spring specifications during an inspection.
Q: Should I replace both springs at the same time, even if only one broke?
A: Yes, and this is a common question. If one spring has reached the end of its service life, the other is typically close behind. they've accumulated the same number of cycles in the same conditions. Replacing both at once saves a second service call and ensures balanced tension across the door.
