If you've lived in Fairmont long enough, you know the humidity here is no joke. Summers are hot and muggy, and the area stays wet and partly cloudy for much of the year. with annual precipitation pushing nearly 48 inches. That kind of moisture isn't just uncomfortable; it quietly goes to work on the metal components of your garage door every single day. Springs are usually the first thing to go.
Understanding why springs fail. and catching the warning signs early. can save you from being stuck with a door that won't budge on a workday morning. Here's what Fairmont homeowners should know.
Garage door springs are rated for a set number of cycles. typically somewhere between 10,000 and 20,000 open-and-close operations. In a normal household, that's roughly 7 to 14 years of use. But in our part of North Carolina, you rarely get the full life out of a standard spring.
The main culprit is moisture. Rust and corrosion significantly accelerate spring failure, especially in humid climates like ours, where moisture attacks the metal coating on the spring wire. Once rust sets in, the metal weakens from the inside out, and a spring that might have lasted another few years can snap without warning.
Temperature swings play a role too. While Fairmont doesn't see much snow. the ground stays snow-free essentially year-round. we do get cold snaps that can push overnight lows into the mid-20s. Cold causes metal to contract and become more brittle, which is why spring failures often spike in winter months. Then summer rolls in and temps climb back toward 90°F. That constant expansion and contraction wears the spring material down faster than steady conditions would.
If your garage is attached to your living space, there's another factor: every time you open the door, you're mixing the interior air with the outside humidity. That repeated exposure speeds up the breakdown of metal components year after year.
Spring failure rarely happens completely out of nowhere. Most doors give you signals first. Here's what to watch for:
- The door feels unusually heavy. Springs counterbalance the weight of the door. If yours suddenly feels like you're lifting a truck, a spring is likely worn or broken. - A loud bang from the garage. A snapping torsion spring often makes a sharp cracking sound. many homeowners mistake it for something falling off a shelf. If you hear it, check immediately. - The door moves crookedly or stops partway. Uneven or restricted movement often means one spring has failed while the other is still working. - Visible gaps in the spring coil. If you look up at the torsion spring above your door and see a gap in the coil, that spring has broken and needs immediate replacement. - Squeaking or grinding during operation. This can mean the spring is dry and corroding. Catching it at this stage gives you time to act before a full break.
For a broader look at components that wear out together, our roller replacement guide covers what else to inspect while you're at it. rollers and springs often degrade on similar timelines.
Most homes in Fairmont and the surrounding Robeson County area have one of two spring types:
Torsion springs are mounted horizontally above the door on a metal rod. They do the heavy lifting through torque, and they're the standard on most modern sectional doors. They tend to last longer and are generally safer when they break, since they stay on the shaft.
Extension springs run along the horizontal tracks on either side of the door. They stretch and contract as the door moves. Older homes. and Fairmont has plenty of housing stock built in the 1960s and 1970s. are more likely to have extension springs.
Whichever type you have, here's a critical piece of advice: replace both springs at the same time. If one breaks, the other has lived the same hard life and will typically fail within months. Replacing both together saves you a second service call and keeps the door balanced.
You can't stop humidity, but you can fight back against it. A few simple maintenance habits go a long way:
1. Lubricate your springs two or three times a year. Use a white lithium grease or a dedicated garage door lubricant. not WD-40, which evaporates too quickly. Coat the spring coils lightly, then cycle the door a few times to distribute it. 2. Do a visual inspection every season. Look for rust spots, visible gaps in the coils, or any deformation in the spring shape. Catching corrosion early means you can lubricate and monitor rather than deal with a surprise failure. 3. Don't ignore other noisy components. A door that's grinding and straining puts extra load on the springs. If tracks are bent or rollers are worn, the springs compensate. and wear out faster.
If you're heading into storm season, it's also worth checking our guide on preparing your garage door for severe weather, since Robeson County residents. from Fairmont to Lumberton to Red Springs. know all too well how damaging a major storm can be to a home's exterior.
This one is worth saying plainly: do not attempt to replace garage door springs yourself. Springs hold tremendous tension even when the door is closed. A broken spring that's mishandled can snap or recoil with enough force to cause serious injury. The tools required to safely wind and tension a torsion spring aren't something most homeowners have sitting in the garage.
This is true whether you're in Fairmont, over in Laurinburg, or anywhere else in the county. The risk simply isn't worth it. A professional can diagnose the exact spring type and size needed for your door's weight, install both springs correctly, and test the door balance. all in a single visit.
If your door is showing any of the warning signs above, contact us to schedule a service call. Fairmont Garage Doors serves the Fairmont area and surrounding communities and can typically get a technician out quickly. You can also browse our full list of services to see everything we handle, from spring replacement to full door installation.
A broken spring will usually show a visible gap in the coil, and the door will either not open at all or feel extremely heavy when lifted manually. A worn spring may still function but will cause the door to move slowly, unevenly, or make grinding noises during operation. Either situation warrants a professional inspection.
No. Operating a garage door with a broken spring puts dangerous strain on the opener motor and cables, and it can cause the door to come down suddenly. Stop using it and call for service as soon as possible.
For most standard residential doors, a professional spring replacement. including both springs. takes between one and two hours. A technician will also check the cables, balance, and hardware while on-site.
