If you've ever walked into your garage on a cold Montgomery County morning and found your door won't budge. motor humming, door dead in its tracks. there's a good chance a spring just gave out. It's one of the most common calls we get at Troy Garage Doors, and it almost always catches homeowners off guard.
Spring failure isn't random, though. Once you understand how these components work and what to watch for, you can often see trouble coming before it leaves you stranded.
Your garage door. even a modest single-car steel panel. weighs anywhere from 130 to over 200 pounds. The springs are what make it feel effortless to lift. They store tension energy when the door closes and release it to counterbalance the door's weight when it opens. Without functioning springs, your opener motor is essentially trying to deadlift a small refrigerator on its own. It won't last long doing that.
There are two types you'll find on homes around Troy and the surrounding Montgomery County area:
- Torsion springs. mounted horizontally above the door opening along a metal bar. These are the most common on modern sectional doors and are generally considered safer and longer-lasting. - Extension springs. found on either side of the door tracks, stretching as the door closes. Older homes in Troy, Candor, and Biscoe often have these on tilt-up style doors.
Most standard garage door springs are rated for about 10,000 cycles. one cycle being a single open-and-close. If you use your garage door four times a day, that works out to roughly 7 years. High-cycle springs rated for 25,000 to 50,000 cycles are available and can last 15,20 years, which makes them worth the upcharge for most homeowners who plan to stay in their home long-term.
Troy's climate also plays a role here. Summers regularly push into the upper 80s and low 90s with muggy humidity, while winters can dip into the upper 20s. that swing of 60°F or more causes metal to expand and contract with the seasons. This thermal cycling puts stress on spring wire over time and can accelerate wear, especially if the springs aren't lubricated regularly.
Don't wait for a complete break. Watch for these early warnings:
- The door feels heavier than normal when you lift it manually. A properly balanced door should feel like roughly 10,15 pounds. Noticeably heavier means the springs are losing tension. - The door won't stay open halfway. Lift the door about 3,4 feet and let go. it should stay put. If it drifts back down, your springs are weakening. - Visible gaps in the coils. A healthy torsion spring has coils that touch each other. If you can see a gap or separation in the coil, the spring is broken. - The opener strains or stops mid-cycle. Your opener isn't designed to carry the full door weight. if the springs aren't helping, the motor overworks and can burn out. - A loud bang from the garage. This is a classic broken spring sound. If you hear a sharp crack and the door suddenly stops working, stop using it immediately and call a professional. - Rust or corrosion on the spring. Rust weakens the metal and increases the risk of sudden failure. Given Montgomery County's humid summers, this is worth checking every spring and fall.

Spring replacement in central North Carolina typically runs $150 to $350 per spring, with most homeowners paying in the $200,$350 range for a standard torsion spring replacement including labor. If you have a heavier two-car door or need both springs replaced at the same visit. which is almost always recommended. budget $300,$500 for the job.
A word on replacing both springs at once: when one spring breaks, the other is usually within a few thousand cycles of failing too. Replacing both during the same service visit saves you a second trip charge and keeps the door balanced. It's almost always the smarter call.
High-cycle spring upgrades cost a bit more upfront but are worth considering if you're tired of repeat service calls. Learn more about what goes into garage door installation and service pricing before you get a quote.
Garage door springs are under enormous tension. enough stored energy to cause serious injury if mishandled. Torsion springs in particular require calibrated winding bars and a precise understanding of the correct tension for your door's weight. An improperly wound spring can snap during installation or fail weeks later, potentially dropping the door unexpectedly.
This isn't a scare tactic. It's a genuine risk that even experienced handymen can underestimate. The cost savings of a DIY attempt rarely justify it. Schedule a professional service call and have it done right the first time.
A professional spring replacement typically takes 45 to 90 minutes. A good technician will:
1. Inspect both springs (and cables, which often wear at similar rates) 2. Confirm the correct spring size for your door's weight and height 3. Remove old springs safely and install the new ones with correct tension 4. Test the door balance manually before reattaching the opener 5. Lubricate all moving parts and note any other hardware showing wear
If your tech skips the balance test or rushes out in under 20 minutes, that's a red flag. A quality job takes time.
Q: Can I still use my garage door if a spring is broken? Technically yes, but you shouldn't. Running your opener with a broken spring puts enormous strain on the motor and drive system. You risk burning out the opener, damaging the door tracks, or. worst case. the door dropping if the other spring gives out too. Stop using it and call for service.
Q: My door has one torsion spring. Should I upgrade to two? Many single-car doors in Troy and nearby Mount Gilead were originally installed with just one torsion spring. Upgrading to a double-spring system improves balance, reduces wear on each spring, and extends the overall lifespan. It's worth discussing with your technician during a replacement visit.
Q: How do I know if it's the spring or the opener that's the problem? Disconnect the opener by pulling the emergency release cord (usually a red handle hanging from the rail). Try lifting the door manually. If it's extremely heavy or won't move smoothly, the springs are the likely culprit. If it lifts easily by hand but the opener still won't move it, the issue is probably with the opener itself.
