Most garage door springs fail without much warning — or rather, they give warnings that most homeowners miss. Here in Port Hadlock, the combination of persistent moisture and freeze-thaw temperature cycling through winter puts springs under more stress than they'd face in a drier climate. Understanding what to look and listen for can save you from a door that refuses to open at 7 a.m. on a workday.
This post focuses specifically on springs. If you're dealing with rust, moisture damage, or weatherstripping issues, check out our related post on how Port Hadlock's wet climate damages garage doors — a lot of the same root causes apply.
Your garage door — whether it's on a classic Cape Cod in the Irondale neighborhood or a newer ranch-style home out toward Port Ludlow — weighs somewhere between 150 and 300 pounds. Springs do the actual lifting. The opener provides the motion, but the torsion springs (mounted above the door on a horizontal shaft) or extension springs (running along the sides of the tracks) counterbalance that weight so the motor isn't straining under full load.
Most standard residential torsion springs are rated for about 10,000 cycles — one cycle being a single open-and-close. At four uses per day, that works out to roughly seven to nine years. Moisture accelerates wear significantly: in Pacific Northwest climates, the wet climate creates persistent moisture exposure that accelerates rust formation on metal springs, shortening that lifespan noticeably.
This is the most dramatic sign, and it's hard to miss. When a torsion spring snaps, it unwinds violently under tension and makes a sharp cracking noise — often described as a gunshot or a car backfire coming from inside the garage. If you hear this and the door stops working, a spring has almost certainly broken. Do not attempt to open the door manually or with the opener. Call for service.
Try this test: disconnect the opener by pulling the red emergency release cord, then try to lift the door manually to about waist height. A properly balanced door should feel light — maybe 10–15 pounds of resistance at most. If the door feels like dead weight, the springs are no longer doing their job of counterbalancing the load. This is also how your opener gets burned out prematurely — it was never designed to lift the door's full weight on its own.
Raise your door manually (with opener disconnected) to about halfway. Let go. A door with healthy springs will stay in place. If it creeps upward or — more dangerously — slides back down, your springs have lost their tension. A door that drops unexpectedly is a serious crush hazard, especially for children or anyone walking underneath.
Look up at the torsion spring above your door. Healthy springs appear smooth and uniformly coiled with consistent tension across the whole length. If you notice a gap of about two inches or more in the coil, that spring has snapped. Extension springs on the sides may not show a clean gap but could appear overstretched or sagging. Either way, don't use the door — call a professional immediately.
If your garage door tilts to one side when opening or closing, or if one side rises faster than the other, one spring has likely failed while the other is still holding tension. This is common on systems with two extension springs. The working spring is now carrying more than its share of the load, which means it's also under more stress and closer to its own failure point. It's worth knowing: professionals typically recommend replacing both springs at the same time, since if one has failed, the other is usually near the end of its life too.
If your opener seems to struggle, makes an unusual humming noise, or stops before the door is fully open, it may be compensating for a spring that's no longer pulling its weight. Your opener is not designed to lift a 200-pound door unaided — continued use in this condition can burn out the motor or strip the drive gears, turning a spring replacement into a much more expensive opener replacement as well.
Port Hadlock homeowners deal with something that garage door owners in drier parts of Washington don't: corrosion-accelerated spring failure. Cold snaps followed by wet days create condensation and repeated moisture exposure that speeds corrosion — and springs are especially sensitive because small weak spots in the metal can dramatically shorten their cycle life. If you see rust building on the spring coils, or if the door has started feeling heavier over the past few months, don't wait for the snap.
For homes near the bay or with garages that face the prevailing northwest winds, marine air influence from the Salish Sea can further accelerate surface corrosion on exposed metal. It's worth checking springs visually each fall — something that takes less than five minutes with a flashlight.
Garage door springs are under extreme tension — enough stored mechanical energy to cause serious injury or worse if released improperly. Replacing them requires specialized winding bars, the right spring sizing for your specific door weight, and experience knowing how much tension to apply. A 150 to 300-pound door can drop suddenly without spring support, and the consequences of getting this wrong are severe.
This is genuinely one of those repairs where the risk isn't worth the savings. Garage Door Port Hadlock carries the right parts and tools for the job and can typically handle a spring replacement in a single visit. If you're seeing any of the warning signs above, reach out to schedule a service call before the problem escalates.
Yes, in almost every case. If one spring has reached the end of its life, the other is typically close behind — they've both experienced the same number of cycles and the same environmental conditions. Replacing both at once saves you a second service call and keeps the door balanced. It's a small additional cost that almost always makes sense.
Torsion springs are mounted horizontally above the garage door opening on a metal shaft — you'll see one or two thick coiled springs running parallel to the top of the door. Extension springs run along the upper horizontal tracks on either side of the door and stretch when the door closes. Most modern residential doors use torsion springs; older or lighter doors may use extension springs. Not sure which you have? Check out our FAQ page for more details.
No. Operating a garage door with a broken spring puts extreme strain on the opener motor and can cause the door to drop suddenly, creating a safety hazard. If you suspect a spring has failed, disconnect the opener and avoid using the door until it's been inspected.
