If you've ever walked into your garage on a January morning and heard a sharp bang. or found the door simply refusing to move. there's a good chance a spring let go overnight. It happens more often in Black Mountain than most homeowners realize, and the timing is almost never a coincidence.
Black Mountain sits in the Blue Ridge Mountains at roughly 2,400 feet elevation, and the winters here are genuinely cold. Temperatures regularly dip into the upper 20s overnight from December through February, and hard freezes below 20°F aren't uncommon. That kind of cold does something specific to the steel in your garage door springs: it makes them brittle, contracts the metal, and increases the chance of a sudden failure. especially on a door that hasn't been maintained in a while.
Your garage door is counterbalanced by either torsion springs (mounted horizontally above the door) or extension springs (running along the tracks on each side). Both types are under enormous tension every single time the door moves. Over time, the repeated cycle of opening and closing fatigues the metal. Cold weather accelerates that fatigue.
Here's what's happening physically: steel contracts in cold temperatures. A spring that's already wound tight from supporting a heavy door becomes even more stressed when temperatures drop. Add in the freeze-thaw cycles common along the I-40 corridor through Swannanoa and into Black Mountain. where you might see 55°F one afternoon and 22°F the next morning. and the metal is flexing constantly. That's a recipe for premature failure.
Lubrication also matters more in winter than most people think. Garage door spring lubricant gets thick and sluggish when it's cold. A spring that moves stiffly puts more load on the motor and the spring coils themselves. If your lubricant hasn't been refreshed since last spring, this winter may be the one that costs you.
Don't wait for the loud bang. There are usually warning signs beforehand:
- The door feels heavier than usual. If you disconnect the opener and try to lift the door manually, a properly balanced door should feel nearly weightless. If it feels heavy or drops when you let go at waist height, the springs aren't doing their job. - The door opens unevenly. One side rising faster than the other often means one spring is weakening faster than the other. common when springs aren't replaced as a pair. - Visible gaps in the spring coil. A stretched-out or separated coil is a spring that's already partially failed. Don't operate the door. - Squeaking or grinding during operation. This isn't just annoying. it signals metal-on-metal friction that's wearing the spring down. - The opener straining or reversing. If your opener is working overtime or the door reverses before fully opening, the springs may no longer be providing adequate counterbalance.
If you're unsure what you're looking at, our frequently asked questions page covers common spring and opener questions in plain language.
There's one spring task homeowners can and should do themselves: lubrication. Use a lithium-based or silicone spray lubricant. not WD-40, which evaporates too fast and can actually attract dirt. Apply it to the spring coils, the hinges, the rollers, and the tracks (but not the track surface itself). Do this at least twice a year, and definitely before the cold sets in. A thorough chain drive and hardware maintenance routine pairs well with this.
Everything else. spring replacement, tension adjustment, cable work. is firmly in professional territory. Garage door springs are under hundreds of pounds of tension. A spring that releases suddenly can cause serious injury. This isn't an exaggeration or a liability disclaimer; it's just the reality of the physics involved. Every technician at Black Mountain Garage Doors has seen what a failed spring can do, and none of them would encourage a homeowner to tackle it.
Most torsion spring replacements in the Black Mountain area run between $150 and $350 for a single-car door, depending on the spring size and whether the cables need attention too. Replacing both springs at once. which we always recommend. adds a modest cost but saves you a second service call when the other spring fails (and it will, since both springs share the same age and wear history).

Homes throughout Black Mountain. from the craftsman-style builds in the Settings neighborhood to the older cabins up toward Montreat. deal with the same mountain weather, but the exposure level varies. Garages on north-facing slopes or in shaded hollows stay colder longer. An uninsulated garage can see temperatures well below outdoor air temps on a clear, calm night due to radiative cooling. If your garage floor regularly freezes or you see frost on interior surfaces, your springs are working in near-freezing conditions every single morning.
For those homes, an insulated garage door makes a meaningful difference. not just in energy costs but in spring longevity. The warmer the spring environment, the less thermal stress with each cycle. Our post on insulation R-value and what it means for your garage explains the options in detail.
Q: How long do garage door springs typically last in a mountain climate like Black Mountain? A: Most springs are rated for around 10,000 cycles. roughly 7 to 10 years for an average household. In colder climates with significant freeze-thaw cycles, you may see springs fail on the earlier end of that range, particularly if they haven't been lubricated regularly. Springs on older doors or doors that see heavy daily use may fail sooner.
Q: Can I still use my garage door if a spring breaks? A: Technically the opener may still run, but we strongly advise against it. Operating a door with a broken spring puts massive strain on the opener motor and the cables, and can cause the door to fall unexpectedly. Disconnect the opener and leave the door closed until a technician arrives.
Q: Should I replace both springs even if only one broke? A: Yes, almost always. Both springs were installed at the same time and have the same number of cycles on them. If one failed, the other is close behind. Replacing both during the same service visit saves labor cost and protects you from a second failure within months.
