7 Warning Signs Your Garage Door Springs Are Failing: and What Happens If You Ignore Them
2026-04-03 7 min read
Most homeowners never think about their garage door springs until something goes wrong. That's understandable. springs are out of sight, and the door just works. But in a place like Ossipee, where temperatures swing from single digits in January to 78°F in July and snowfall runs from October through May, those springs are working in one of the most demanding environments in New England. They wear out faster here than they would in a milder climate, and when they fail, they rarely fail quietly.
Knowing what to look for can save you from an emergency service call. or worse, from a 200-pound door dropping unexpectedly.
What Springs Actually Do
Your garage door's springs are doing the real lifting. The door itself. whether it's a single Colonial-style panel on a classic Ossipee home or a larger double door on one of the newer builds going up around the lakes region. weighs anywhere from 130 to over 300 pounds. The springs counterbalance that weight so your opener motor only has to guide the movement, not haul dead weight. When the springs are healthy, the door feels nearly weightless. When they're failing, the opener compensates by working much harder than it was designed to.
There are two types of springs you'll find on residential doors. Torsion springs mount horizontally above the door opening and use torque to lift. Extension springs run along the sides of the door and stretch as the door closes. Both types are under significant tension at all times, which is what makes spring work genuinely dangerous for anyone without the right training and tools.
7 Signs Your Springs Are Wearing Out
1. The Door Feels Heavy
This is the simplest test. Disconnect your opener by pulling the red emergency cord hanging from the carriage, then try to lift the door manually to about waist height. A properly balanced door should rise smoothly and stay put when you let go. If it feels like you're lifting the actual weight of the door, or if it drifts back down when you release it, the springs are no longer providing the counterbalance they should. This test takes about 30 seconds and is worth doing once a season.
2. A Loud Bang from the Garage
A torsion spring snapping under full tension makes a sound that many homeowners describe as a gunshot or a firecracker going off inside the garage. If you hear this. especially if it's followed by the door refusing to open. stop using the door immediately. Do not keep cycling the opener. A broken spring means the opener is suddenly managing the full weight of the door, which will destroy the motor and potentially cause the door to drop.
3. Visible Gaps in the Spring Coils
Look at your torsion spring above the door. It should be one continuous, tightly wound coil with no interruptions. A gap of an inch or two in the middle means the spring has snapped and separated. This is a clear signal that the spring needs to be replaced before the door is used again. You can also inspect extension springs on the sides of the door for visible stretching, sagging, or loose coils.
4. The Door Opens Unevenly or Tilts to One Side
If one spring has failed while the other is still functioning, the door will lift unevenly. one side rises higher than the other, creating a lopsided appearance. This asymmetric load puts enormous stress on the cables, the opener, and the tracks. Left alone, it will pull cables off their drums and bend the track out of alignment. The whole system is connected; one failing component tends to take others with it. Our cable repair guide covers what can happen downstream when spring tension is lost.
5. The Opener Strains or Makes Unusual Noises
Openers are designed to guide a balanced door, not to lift a door on their own. If your opener is humming louder than usual, hesitating mid-lift, or stopping before the door is fully open, it's often compensating for springs that have lost tension. Running the opener in this condition accelerates motor wear significantly. If your springs are near the end of their lifespan, you're essentially burning through your opener as well.
6. Rust or Corrosion on the Spring
Ossipee's high winter humidity. January and February see average relative humidity of around 86%. combined with the road salt that gets tracked into garages on vehicles creates ideal conditions for spring corrosion. Rust weakens the metal and makes springs more prone to sudden failure. During your periodic inspections, look for reddish-brown discoloration, flaking, or pitting on the spring surface. A rusty spring should be replaced proactively; it won't give you much warning before it snaps.
7. The Door Slams Shut
A healthy spring system absorbs momentum during the closing cycle, guiding the door down at a controlled speed. When springs lose tension, that damping effect disappears. If your door is closing faster than it used to. or drops with a bang. the springs are no longer doing their job. This is a safety issue that needs immediate attention, especially in homes with children or pets.
How Long Should Springs Last?
Most standard torsion springs are rated for about 10,000 cycles, where one cycle equals one full open-and-close. At four cycles per day. roughly what a typical household in North Conway or Ossipee might use. that works out to somewhere between seven and nine years. Heavy use shortens that lifespan considerably. Cold-climate conditions like ours, with the repeated freeze-thaw cycles and humidity exposure, can also accelerate wear.
If your springs are approaching the seven-year mark, it's worth having them inspected even if everything seems fine. Replacing springs on a schedule. rather than after they snap. is almost always cheaper and safer. Check out our installation and service pricing guide for a realistic sense of what spring replacement typically involves cost-wise.
Why You Shouldn't Replace Springs Yourself
This is the one garage door repair we always recommend leaving to a professional, no exceptions. Torsion springs are wound under hundreds of pounds of torque. Without the proper winding bars, clamps, and training, releasing that tension can result in broken fingers, facial injuries, or worse. A 200-pound door dropping without spring support is genuinely dangerous. The repair itself, when done correctly, typically takes a professional 60 to 90 minutes. It's not worth the risk to save a service fee.
When a technician replaces springs, they should also inspect the cables, rollers, and opener. because these components share the workload and often show related wear. If you've noticed any of the signs above, contact Ossipee Garage Doors to get a proper diagnosis before something more serious fails.
Frequently Asked Questions
Q: Should I replace both springs at the same time, or just the one that broke? A: Replace both. Springs wear together, and if one has broken, the other is typically close behind. Installing a new spring alongside an old, fatigued one creates an imbalance, and the older spring is likely to snap within months anyway. Replacing the pair at the same visit saves you a second service call and keeps the door properly balanced. Visit our FAQ page for more common questions about spring service.
Q: Can I keep using my garage door if one spring is broken? A: No. With one spring broken, the opener is handling the full weight of the door, which will burn out the motor quickly. The door is also at risk of dropping unexpectedly, which is a serious safety hazard. Disconnect the opener and leave the door down until the springs are replaced.
Q: How do I know which type of springs my garage door has? A: Look at the door from inside the garage. If you see a single horizontal spring (or two springs) mounted on a metal shaft directly above the door opening, those are torsion springs. If you see springs running along the horizontal tracks on either side of the door, those are extension springs. Both types wear out and both are hazardous to work on without proper training. but a technician will know immediately which system you have and what's needed.
