After 15 years pulling springs and rebuilding doors across Braintree and the surrounding towns, I can tell you that most homeowners don't understand what's holding their garage door up. The springs are doing almost all the heavy lifting, and when one snaps, your door becomes a 300-pound paperweight. Let's cut through the confusion about garage door springs so you know what you're dealing with.
Your garage door uses one of two spring systems, and knowing which one you have saves time and money when repairs are needed.
Torsion springs sit on a metal rod above your door opening. They twist and unwind to lift the door. These are the most common type I see in residential Braintree homes built in the last 20 years. A typical residential door has one or two torsion springs rated for 7,000 to 10,000 cycles. That translates to roughly 7 to 9 years of daily use before they wear out.
Extension springs run along the sides of your door frame. They stretch and contract to help lift the door. These are older, less efficient, and honestly, I recommend replacing them with torsion systems when the time comes. Extension springs wear faster and require more maintenance.
The key difference: torsion springs handle the load more evenly and last longer. If you're not sure which type you have, look above the door opening. See a wound metal rod? That's torsion. See springs on both sides running parallel to the tracks? That's extension.
Springs break for predictable reasons. Most commonly, they simply wear out. Each time your door opens and closes, the metal fatigues a tiny bit. After thousands of cycles, metal gets brittle and snaps.
Temperature swings accelerate this. Braintree winters are rough on springs. Cold metal becomes more brittle, and the constant contraction and expansion stresses the material. I've replaced more springs in January and February than any other months.
Rust is another killer. If your garage isn't climate-controlled, moisture corrodes the spring from the inside. A small rust pit becomes a crack, and boom, you've got a snapped spring.
Here's what I tell customers: do not attempt to replace a spring yourself. I've treated injuries from broken springs. The tension in these springs is enormous. A snapped spring can fly across your garage at dangerous speed. Call a professional. We have the right equipment, insurance, and experience to do this safely.

Spring replacement typically costs between $150 and $400 per spring in Braintree, depending on the type and quality. If both springs need replacing (which often happens when one fails), expect $300 to $800 total, plus labor.
Why the range? Premium springs last longer. A commercial-grade torsion spring might cost more upfront but gives you 10,000 cycles instead of 7,000. Over nine years, that's better value. A budget spring saves you money now but may need replacement sooner.
Labor usually runs $100 to $200 per spring. We handle the entire job in about an hour. Many homeowners don't realize that if one spring fails, the other is likely close behind. I almost always recommend replacing both at once. It's cheaper than a service call six months later.

You can't stop springs from aging, but you can slow it down. Lubricate your springs twice a year with a garage door lubricant (not WD-40). This reduces friction and rust risk.
Keep your garage reasonably dry. If condensation pools on the floor or walls, address it. A dehumidifier in humid months helps. This is especially important during New England's damp springs and fall.
Have your door inspected annually. We look for rust, corrosion, and spring wear before failure happens. Catching a weak spring early means you avoid that panicked call when your door gets stuck.

If your door opens and closes but feels slower, jerks, or makes creaking sounds, springs may be wearing out. If you hear a loud bang or your door won't open at all, a spring has likely snapped. Both situations need professional attention.
We service all of Braintree and nearby areas with same-day availability most days. Don't wait. A broken spring puts stress on your opener and door panels. The longer it sits, the more damage accumulates.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (roughly 7,000 to 10,000 cycles). Extension springs wear faster, often 5 to 7 years. Lifespan depends on door use frequency, climate, and maintenance.
Can I replace just one spring? Technically yes, but we recommend replacing both. When one fails, the other is usually near the end of its life. Replacing both at once prevents another service call in six months and keeps your door balanced.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly, often with a loud bang. Your door won't open. A worn spring degrades gradually, making your door feel slower or jerky before it finally breaks. Both need replacement.
Is a garage door spring repair an emergency? Not a life-threatening emergency, but you should call within a day or two. A broken spring prevents normal door operation. Your garage is inaccessible, and a stressed opener can fail next.
Why can't I replace the spring myself? Spring tension is extremely dangerous. A snapped spring can cause serious injury. The tools required are specialized. Professional replacement ensures safety, proper installation, and warranty coverage on parts and labor.
