Your garage door won't budge. You hit the opener button, hear a loud twang, and nothing happens. Most people don't think about their garage door until it stops working, and when a spring snaps, you're facing an immediate problem. Garage door springs in Dartmouth typically last 7 to 9 years before wearing out. A snapped spring means your door is stuck, your car is trapped, and you need professional help fast.
Garage door springs fail for predictable reasons, but homeowners often miss the warning signs. Torsion springs bear the full weight of your door and open/close thousands of times per year. Over time, metal fatigues. The constant twisting and unwinding weakens the coil until it snaps suddenly.
Poor maintenance speeds up failure. Rust, dirt, and lack of lubrication cause springs to work harder. Cold weather in coastal Massachusetts also accelerates wear because metal contracts and becomes brittle. A spring that might last nine years in ideal conditions could fail in six if neglected.
Extension springs, found on older doors, have a different failure pattern. They can break due to broken safety cables or worn pulleys. When one fails, the other often follows within weeks because it now carries extra load.
The hard truth: springs don't warn you much. One day they're holding fine. The next day, a tiny crack becomes a complete break. This is why regular tune-ups catch problems early.
Replacing a snapped spring isn't cheap, but it's cheaper than ignoring the problem. A single torsion spring replacement typically runs $150 to $300 per spring, depending on your door's weight and spring quality. If both springs fail (common), expect $300 to $600 for the pair.
Labor adds another $100 to $200 because the work requires specialized tools and safety knowledge. DIY spring replacement kills homeowners every year. The tension in these springs is enormous. A slip means serious injury.
Calling for a same-day service costs more. Dartmouth homeowners in a bind sometimes pay rush fees. That's why preventive maintenance saves money long-term. A $150 annual inspection catches worn springs before they snap, avoiding the emergency call and premium pricing.

Before a spring snaps, it sends signals. If your door opens and closes slower than normal, springs are weakening. If the door feels heavier to lift manually, springs are losing tension. A gap in the spring itself means replacement is imminent.
Rust on springs is another red flag. Spring coating protects against moisture, especially important near Dartmouth's coastal climate. Once rust takes hold, failure accelerates. A little surface rust means you have weeks, not months.
Strange noises during operation also matter. Squeaking or creaking isn't normal. It means friction is building and lubrication is gone. Address this before springs snap.
Our guide on garage door spring warning signs in Dartmouth covers these details in depth. Catching problems early keeps your door working and your wallet intact.
Once a spring snaps, repair means replacement. You can't weld or patch a broken spring safely. The repair cost is essentially the replacement cost.
However, if only one of two springs failed and the other is in decent shape, you have a choice. Replace both springs now for $300 to $600, or replace one and plan for the second failure in a year or two. Most budget-conscious homeowners replace both at once because it avoids a second service call.

You can't stop springs from aging, but you can slow it down. Lubricate springs every six months with garage door lubricant, not WD-40. Keep the garage clean to minimize rust. Run the door through its cycle regularly to maintain tension even if you're not using it daily.
Annual maintenance catches worn springs before they break. Garage Door Dartmouth includes spring inspection in our maintenance program. The cost is minimal compared to emergency replacement.

How long do garage door springs last? Most torsion springs last 7 to 9 years with normal use. Extension springs typically fail sooner, around 5 to 7 years. Lifespan depends on usage frequency, maintenance, and climate. Coastal areas like Dartmouth see faster wear due to salt air and moisture.
Can I replace a garage door spring myself? No. The tension in garage door springs is extremely high. A slip during replacement can cause serious injury or death. Professional technicians have the proper tools and training. The labor cost is small compared to the safety risk of DIY work.
How much does spring replacement cost near me? Single spring replacement costs $150 to $300 plus labor. Replacing both springs runs $300 to $600 total. Same-day emergency service may include rush fees. Get an estimate before committing.
What's the difference between torsion and extension springs? Torsion springs twist to lift the door and mount above it. Extension springs stretch and pull the door up, mounting on the sides. Torsion springs are safer and more durable. Most modern doors use torsion springs.
Should I replace both springs if only one snapped? Yes. The second spring is under the same stress and will likely fail within months. Replacing both avoids a second service call and costs less than two separate visits.
