Garage door springs fail without warning, and when they do, your door won't open. The two main types are torsion springs (wound above the door) and extension springs (mounted on the sides). A snapped spring means you need professional help immediately. This guide walks you through what these springs do, how long they last, and when to call a technician.
Your garage door weighs between 300 and 500 pounds. Springs counterbalance that weight so your opener doesn't strain itself lifting dead weight every single day. Without them, your 1/2-horsepower opener would burn out in months.
Torsion springs twist tightly around a horizontal rod above the door. They store and release energy through rotational force. Extension springs stretch and contract as the door moves, pulling cables that help lift the panels. Both types work under extreme tension. Both can fail catastrophically if installed wrong or maintained poorly.
Springs typically last 7 to 9 years with normal use (roughly 10,000 cycles). That's about 3 to 5 cycles per day for an average household. Heavy use, rust, and temperature swings in the North Carolina mountains can shorten this lifespan significantly.
A snapped spring produces a loud bang or crack. Your door may go slack, refuse to open, or hang unevenly. You might hear grinding or creaking before failure occurs.
Other warning signs include slow door movement, the door dropping faster than usual when closing, and visible rust or corrosion on the metal. If your door opener is running but the door isn't moving, springs are the first suspect.
Don't ignore these warnings. A broken spring puts dangerous stress on your opener and door cables. It also creates a safety hazard for anyone underneath. If you're noticing these issues around Murphy or the surrounding areas, a trained technician should inspect the system before you use it again.
Look above your garage door on the inside. If there's a horizontal rod with a spring wound tightly around it, you have a torsion spring setup. Most newer homes and heavier doors use torsion springs because they're more reliable and safer.
Extension springs run along the sides of the door frame. They look like coils that stretch and compress. Older homes and lighter doors often have these. Extension springs require safety cables running through them to catch them if they snap. Without those cables, a broken extension spring becomes a projectile.
Both types require professional replacement. The tension is high enough to cause serious injury if you attempt this yourself. Review our complete services page to understand your repair options.

Lubricate springs twice a year with garage door lubricant (not WD-40). This reduces rust and friction. Keep the door balanced by testing it monthly. Open it halfway and let go. It should stay put without creeping up or down.
Also check the area around your springs for debris, moisture, and corrosion. In the foothills of Western North Carolina, humidity and temperature swings create rust faster than in drier climates. Winter weather can also affect performance. Learn more about preparing your door for cold weather.
If your door is hanging unevenly, making unusual noises, or moving slowly, springs are likely the problem. Never attempt to adjust or replace them yourself. The tension can cause serious injury or death.
A professional technician has the right tools, replacement parts, and knowledge to do the job safely. We'll inspect your entire system, diagnose the real issue, and fix it right the first time.
Your garage door operates hundreds of times per year. Springs are the heart of that system. Treating them with respect and maintaining them properly keeps your family safe and your door running smoothly.

How do I know if my garage door spring is broken? A loud bang or crack followed by the door refusing to open is the clearest sign. The door may hang unevenly or drop faster when closing. If your opener runs but the door doesn't move, springs are usually at fault.
Can I replace a garage door spring myself? No. Springs operate under extreme tension (up to 400 pounds of force). Improper release or installation can cause serious injury or death. Always hire a licensed technician for spring work.
How long do garage door springs last? Most springs last 7 to 9 years under normal use (10,000 cycles). Heavy use, rust, and harsh weather in the mountains can reduce lifespan to 5 or 6 years.
What's the difference between torsion and extension springs? Torsion springs wind above the door and twist to lift it. Extension springs run along the sides and stretch. Torsion springs are safer, more durable, and used in most modern homes.
How much does spring replacement cost? A single spring typically costs $150 to $300. Replacing both springs together runs $250 to $500 total. Cost varies by spring type, door weight, and additional repairs needed.
