It usually happens at the worst possible time. You press the button on a cold January morning, the opener hums, and the door doesn't budge. or barely lifts a few inches before stopping. For a lot of Dartmouth homeowners, that's the moment they find out their garage door spring has broken. The frustrating part is that broken springs almost always give warning signs first. The problem is most people don't know what to look for.
This is a breakdown of exactly what those signs are, what's normal versus what's not, and when to call for help. before a worn spring turns into an emergency on a February morning when temperatures are dropping below freezing.
Your garage door weighs somewhere between 150 and 400 pounds depending on the material and size. The springs do the heavy lifting. literally. They counterbalance the door's weight so the opener motor (and you, if you lift manually) only has to manage a fraction of the actual load.
There are two common spring systems:
- Torsion springs. mounted horizontally on a metal bar above the door opening. These are more common in modern homes, more durable, and tend to fail more predictably. - Extension springs. run along the horizontal tracks on either side of the door. Older homes, including many of the ranch-style and colonial builds throughout Dartmouth and neighboring New Bedford, still use this system.
Springs are rated by cycles. one cycle equals one full open and close. Most standard torsion springs last around 10,000 cycles, which at four uses per day translates to roughly seven to nine years. In Dartmouth's humid, coastal climate, where salt air accelerates rust on metal components, that lifespan can be shorter. Cold New England winters are also hard on springs. metal contracts in the cold, and a spring that's already stressed can snap during the first frigid morning of the season.
This is one of the clearest early signals. Disconnect your opener and try lifting the door manually to about waist height. it should hold its position without you supporting it. If the door feels like it weighs a ton, or slowly creeps back down when you let go, the springs are losing tension. A door that drops unexpectedly is a serious crush hazard, especially for children or pets near the garage.
If your garage door appears to tilt to one side when opening or closing, one spring has likely failed while the other is still functioning. This imbalance puts extra stress on your opener and the remaining spring. meaning the second spring often follows the first in short order if you keep using the door. Continuing to run the opener with a failed spring can also burn out the motor or strip internal gears, turning a spring replacement into a much larger repair bill.
A torsion spring breaking under tension releases stored energy very suddenly. When a torsion spring breaks, it releases a significant amount of stored tension all at once. the sound is often compared to a gunshot or a car backfire. If you heard something like that from your garage and now the door won't open properly, that's almost certainly a broken spring. Stop using the door and call for service.
Take a look at the torsion spring above your door (if you have one). Torsion springs are tightly wound coils. if you notice a gap of about two inches or more in the spring, that means it has snapped. The spring is broken and the door should not be used. Extension springs may not show a gap, but can appear visibly overstretched or hanging loose along the tracks.
Garage door openers are not designed to lift the door's full weight on their own. that's the spring's job. If the opener seems to strain, makes unusual noises, or stops before the door is fully open or closed, your springs may not be providing adequate support. Running the opener in this condition over time can cause the motor to burn out. If you've noticed the opener working harder than it used to, have the spring tension checked before the motor gives out.
Rust on torsion springs weakens their structural integrity, increasing the risk of sudden failure. This is especially relevant in Dartmouth, where coastal humidity and winter road salt in the air accelerate corrosion on metal components. A rusty spring is more brittle and prone to snapping. If your springs show orange discoloration, that's not cosmetic. it's a real warning sign. Regular lubrication with a silicone-based spray every three months creates a barrier that slows this process.
Spring replacement is one garage door repair you should never attempt yourself. Springs operate under extreme tension. sometimes hundreds of pounds of stored force. When released improperly, they can cause serious injury. Professional technicians have specialized winding bars, safety equipment, and training to handle this safely. Even experienced DIYers get hurt attempting spring replacements.
If you suspect a broken spring, stop using the door. Don't try to force it open manually or run the opener repeatedly hoping it'll catch. You risk damaging the opener, bending the tracks, or worse. having the full weight of the door drop suddenly.
If one spring fails and the other is the same age, replacing both at the same time is the smart move. You want both springs to experience the same amount of wear, which maintains the safety and balance of the door. A technician who only replaces the broken spring is saving you money short-term but setting you up for another service call in a few months when the second spring gives out.
For homeowners in Dartmouth, Acushnet, and nearby Fairhaven, the seasonal stress on springs means this question comes up often. particularly in late winter and early spring when freeze-thaw cycles have been hard on hardware for months.

How do I know if my garage door spring is broken versus a problem with the opener? Disconnect the opener (there's usually a red pull cord hanging from the rail) and try to lift the door manually. If the door is extremely heavy or won't lift at all, the spring is likely the problem. not the opener. If the door lifts smoothly by hand but the opener still won't move it, the issue is with the opener itself. A technician can confirm either way quickly.
How long do garage door springs typically last in the Dartmouth area? Most torsion springs are rated for around 10,000 cycles. roughly seven to nine years at average use. In coastal South Coast towns like Dartmouth, humidity and salt air can accelerate rust on the coil metal, potentially shortening that lifespan. Heavy use (a busy household opening the door six or more times per day) and temperature extremes during New England winters also wear springs faster. If your springs are over seven years old, it's worth having them inspected.
Is it safe to use my garage door if I think a spring might be failing? No. If you notice warning signs. the door feeling heavy, moving unevenly, making loud noises, or if you heard a bang. stop using the door. Running the opener with a failing or broken spring can damage the opener motor, bend tracks, and creates a genuine safety hazard if the door drops unexpectedly. Call a professional before using the door again.
