Most homeowners don't think about their garage door springs until one breaks. And when it does. usually without warning, often at the worst possible moment. it sounds like a gunshot going off in the garage. The door stops working, and suddenly you're either stuck inside or locked out.
In Salisbury and the surrounding Rowan County area, we see spring failures peak at predictable times: late winter when sustained cold temperatures make metal components brittle, and again mid-summer when the heat and humidity accelerate corrosion. If your door is more than seven years old and you're using the garage as your primary entry point. which is the case for most homes in neighborhoods from the West End to the newer developments off Statesville Boulevard. it's worth knowing the warning signs before you're caught off guard.
Torsion springs and extension springs are the two types you'll find on residential garage doors. Torsion springs are the horizontal coil mounted above the door opening. the most common setup on modern homes. Extension springs run along the horizontal tracks on either side and are more typical on older garage doors.
Both types are rated by cycles. one cycle equals one full open and one full close. Standard residential springs are typically rated for around 10,000 cycles. For a household that opens the garage door four times a day, that works out to roughly seven years. Busy families who use the garage as the main entrance and exit can burn through that cycle count in five years or less.
That cycle count doesn't even factor in Salisbury's humidity, which accelerates corrosion on spring coils. A rusty spring is more brittle and far more likely to snap before reaching its rated cycle count.
This is often the first sign. Garage door springs counterbalance the full weight of the door. sometimes 200 pounds or more. When the springs lose tension, that weight shifts to your opener's motor or to your own arms if you're lifting manually. If the door feels heavier than it used to, or if your opener strains and slows down during lifting, the springs are likely losing tension.
If your opener activates but the door only rises 3,6 inches before stopping, your opener's built-in safety feature is detecting that something is wrong with the load. This almost always points to a broken or severely weakened spring. Stop using the door immediately and call a technician.
A snapping torsion spring makes a sharp, sudden noise that homeowners consistently describe as sounding like a gunshot or a car backfiring. If you hear this. especially if it comes from inside the garage when the door isn't in use. a spring has broken. The door will likely be inoperable or extremely dangerous to operate. Do not attempt to open it.
If you can safely look at your torsion spring above the door opening, check for a gap in the coils. A 2,4 inch separation in the coil means the spring has snapped. This is definitive. the spring must be replaced before the door is used again. For extension springs on older Salisbury-area homes, look for a spring that appears stretched out, hanging loosely, or visibly uneven compared to the opposite side.
When one spring fails on a two-spring system, the door loses balanced support and can rise unevenly. one side higher than the other, or with a visible tilt. The door may also jerk or shake during operation. This is a sign that one spring has failed and the other is carrying the full load. which means the second spring is likely to fail soon as well.
This kind of uneven movement is also hard on your tracks. Our guide on track alignment problems explains how an unbalanced door accelerates track wear and can create additional costly damage if not addressed quickly.
In Salisbury's humid climate, springs that aren't regularly lubricated develop rust. A corroded spring has reduced flexibility, making it more prone to snapping under load. If you can see surface rust, discoloration, or pitting on the spring, have it inspected. Don't wait for the snap. that's the more dangerous and more expensive outcome.
A well-functioning garage door is relatively quiet. If you're hearing new squeaking, grinding, or creaking sounds when the door moves. sounds that don't go away after lubrication. the springs may be under improper tension or experiencing accelerated wear. This is an early-stage warning sign that deserves attention before it becomes a full failure.
This is one of the most important points in this entire post: do not attempt to replace garage door springs yourself. This isn't an exaggeration for liability reasons. it's a genuine safety concern.
Garage door springs are under extreme tension at all times. When a torsion spring snaps, it releases that stored energy violently. Professional technicians use specialized winding bars and follow strict procedures specifically because mishandling a spring can cause severe injury. The tension involved is enough to break bones or cause life-threatening harm.
For homeowners in the Salisbury area. and those commuting from Concord or Mooresville who depend on quick garage access. the smartest move when you notice any of the warning signs above is to schedule a service call before a full failure occurs. Planned repairs are faster, safer, and less expensive than emergency calls after a spring snaps and leaves a car trapped inside.

A few simple habits make a meaningful difference:
- Lubricate springs every three months with a silicone-based spray. This reduces friction and limits rust formation, especially important in Salisbury's humid summers. - Test the door balance twice a year. Disconnect the opener, lift the door manually to about waist height, and let go. A properly balanced door stays in place. If it drops or rises on its own, the spring tension is off. - Avoid unnecessary cycles. Every open-and-close shortens spring life. If you're in and out of the garage multiple times during a weekend project, close it only when necessary. - Ask about high-cycle springs when it's time for replacement. Springs rated for 20,000+ cycles cost more upfront but can last two to three times longer than standard springs. a worthwhile investment for active households.
For context on the broader maintenance picture, our post on smart garage door features covers how modern openers can alert you to unusual door behavior. which can be an early indicator of spring issues before they become visible.
Q: How do I know if I have torsion springs or extension springs? A: Look above the door when it's closed. If you see a single horizontal coil (or two coils) mounted on a metal rod running across the full width of the door, those are torsion springs. If you see long, stretched springs running parallel to the horizontal tracks on each side of the door, those are extension springs. Torsion springs are more common in newer construction; extension springs are typical in older homes.
Q: If one spring breaks, do I need to replace both? A: In almost every case, yes. Both springs are the same age and have the same number of cycles on them. If one has failed, the other is typically close behind. Replacing both at the same time saves on a second service call and prevents the second failure from happening when the door is in use. which is the more dangerous scenario.
Q: Can I still use my garage door if I think a spring is failing but it hasn't broken yet? A: You can use it with caution in the short term, but you should schedule a repair as soon as possible. Continuing to operate a door with a weakened spring puts extra strain on your opener's motor, risks cable damage, and could result in sudden uncontrolled door movement. If the door already feels heavy, moves unevenly, or makes unusual noises, treat it as urgent. not something to put off until next month.
