How to Tell If Your Garage Door Springs Need Replacing: A Straight-Talk Guide for Manchester Homeowners
2026-03-27 6 min read
There's a sound most Manchester homeowners only hear once. a sharp bang from the garage, like something heavy dropped or a car backfired. If that's happened to you, there's a good chance a garage door spring just let go. The good news: springs usually give you warning signs before they fail completely. The bad news: most people don't know what to look for.
This guide covers the real signals that your springs are wearing out, what they mean, and why this particular repair is one you should never attempt yourself.
What Springs Actually Do
Your garage door weighs anywhere from 150 to 300 pounds depending on the material and insulation. The springs. either a torsion spring mounted horizontally above the door, or extension springs running along the side tracks. are what make that weight manageable. They counterbalance the door so your opener only has to handle a fraction of the load. Without functioning springs, your opener is trying to lift the full dead weight of the door alone, which it's simply not built to do.
In Manchester's older neighborhoods like Hanover Hill and the North End, many homes have garages built in the mid-20th century with original hardware that's never been upgraded. Even in newer developments out toward Hooksett and Merrimack, springs eventually wear out. it's just a matter of cycles, not calendar years.
How Long Do Springs Actually Last?
Most standard torsion springs are rated for around 10,000 cycles. one cycle being one full open and one full close. If your household opens the garage door four times a day, that works out to roughly seven years of use. High-cycle springs can last 20,000 cycles or more and are worth the investment if you use your garage as a main entryway. Frequent use, heavier doors, and cold temperatures that make metal more brittle can all shorten that lifespan considerably.
If your springs are between seven and ten years old and you're starting to notice any of the signs below, it's worth getting them looked at before they fail outright. A planned replacement is always cheaper and safer than an emergency one.
Warning Signs Your Springs Are Failing
The Door Feels Heavy or Won't Lift
Here's a simple test: disconnect your opener by pulling the red emergency cord, then try lifting the door manually to about waist height. A properly balanced door should feel light. almost like it's helping you. If it feels like you're lifting a car hood with no prop rod, the springs are no longer doing their job. This is one of the clearest signs of failing or broken springs.

A Loud Bang You Heard from Inside the House
When a torsion spring snaps, it releases all its stored tension at once. The sound is startling. homeowners often describe it as a gunshot or a heavy object falling. If this has happened, do not operate the door. Do not use the opener and do not try to open it manually. The door is now unsupported and could drop unexpectedly. Call a professional immediately.
The Door Opens Unevenly or Tilts to One Side
If one side of the door rises faster than the other, or the door looks lopsided as it moves, one spring has likely failed while the other is still functioning. This uneven strain doesn't just look wrong. it puts stress on the cables, rollers, and tracks, which can cause a cascade of additional damage if you keep using the door. If you're noticing this alongside any track issues, our track alignment guide explains what to look for there as well.
Visible Rust, Gaps, or Stretched Coils
Take a look at your springs directly. On torsion springs, a visible gap between the coils means the spring has snapped. On extension springs, look for coils that appear stretched out or loose rather than tightly wound. Rust is also a red flag. a corroded spring is brittle and far more likely to fail suddenly. Manchester's humid summers and salt-heavy winters accelerate this corrosion, especially in garages without good ventilation.
The Opener Strains, Hums, or Stops Mid-Cycle
Your opener is a motor designed to work with a balanced door, not against dead weight. If it's making more noise than usual, hesitating, stopping partway through the cycle, or reversing without cause, the springs may no longer be providing adequate support. Continuing to run the opener in this condition can burn out the motor. turning a spring replacement into a spring-plus-opener replacement.
The Door Slams Shut or Closes Too Fast
Healthy springs absorb momentum during the closing cycle, ensuring a controlled, gentle descent. If your door is closing faster than it should or dropping with more force, the springs have lost that ability. This is a safety issue, not just an inconvenience. A door that falls unexpectedly can injure anyone underneath it.
Why You Should Never Replace Springs Yourself
This point is worth being direct about. Torsion springs are wound under hundreds of pounds of stored tension. When released improperly. or if a spring slips during DIY winding. the energy releases violently, and the injuries can be severe. This isn't a matter of being handy or not handy. It requires specific winding bars, knowledge of the exact spring specifications for your door weight, and experience handling components under extreme tension.
Most professional repairs also include inspecting the cables, drums, and hardware at the same time. things that wear out alongside springs and are worth addressing together. You can explore what a full-service visit covers on our services page.
Both Springs, Not Just One
If one spring breaks, the other one isn't far behind. they've been on the same cycle count since they were installed. Manchester Garage Doors and most reputable shops will recommend replacing both springs at the same time. It costs only marginally more, and it means you won't be dealing with the second failure a few months later.
Frequently Asked Questions
Q: How do I know if I have torsion springs or extension springs? A: Torsion springs are the horizontal coil (or coils) mounted directly above the garage door on a metal shaft. Extension springs run parallel to the horizontal tracks on either side of the door and stretch when the door closes. Most newer homes use torsion springs; older garages more commonly have extension springs.
Q: My garage door is only about five years old. Can the springs already be failing? A: Yes. Spring lifespan is measured in cycles, not years. A busy household that opens the garage eight to ten times a day will wear out springs in five years or less. Heavier doors, poor lubrication, and high humidity all shorten spring life further. If you're seeing any warning signs, age alone isn't a reason to wait.
Q: Is there anything I can do to extend spring life? A: Lubricate your springs two or three times a year with a silicone or lithium-based spray. this reduces friction and slows corrosion. Also make sure your door is properly balanced; a door that's off-balance puts uneven strain on the springs. Annual professional inspections catch wear early, and a simple tune-up often extends spring life by catching small issues before they compound.
