In our 15 years serving Boston homeowners, we've seen this problem again and again: a garage door that won't budge, and the culprit is almost always a snapped spring. When your garage door springs fail, your door becomes a 400-pound paperweight. The good news? This is fixable, and understanding the types, costs, and timeline can save you stress and money.
Your garage door relies on one of two spring types: torsion springs or extension springs. Torsion springs sit above the door and twist to counterbalance weight. Extension springs run along the sides and stretch to help lift. Both are under constant tension, coiling and uncoiling thousands of times over their lifespan.
Springs typically last 7 to 9 years, depending on usage and climate. Boston winters accelerate wear. Cold temperatures make metal brittle, and salt air corrodes hardware. When a spring finally snaps, you'll hear a loud bang. Your door won't open, or it'll fall suddenly. Don't try to force it. A broken spring can't support the door's weight, and you risk injury or damage.
Not every spring failure is sudden. Watch for these warning signs:
Your door moves slowly or feels heavy when opening. The door hangs unevenly on one side. You hear creaking or squeaking near the top. Your door opener runs but the door barely budges. These are red flags that springs are weakening and a snapped spring is coming soon.
If you've noticed these issues, we recommend getting a free estimate before something breaks. This is especially important as you prepare for warmer months. Check out our guide on preparing your garage door for summer to see how spring condition fits into your overall maintenance plan.
Torsion springs are mounted horizontally above your door. They're more durable, quieter, and safer because they're enclosed. Most modern homes use torsion springs. They cost more upfront but last longer and handle frequent use better.
Extension springs are mounted on each side of the door and stretch as it opens. They're cheaper but wear faster and require safety cables to prevent injury if they snap. Older Boston homes often have extension springs.

For broader context on garage door repair pricing in your area, our garage door cost and pricing guide breaks down other common repairs and how spring work fits into your overall investment.
A broken spring leaves you without access to your garage. You can't park your car, reach tools, or get to stored items. Families with young children or elderly members especially need quick solutions. We prioritize same-day spring replacement because we know you can't wait.
Spring replacement is also a safety issue. A door without working springs is unstable and dangerous to operate. Kids or pets could be hurt. Thieves might exploit the access. The sooner you get it fixed, the safer your home is.
We understand the temptation to save money on DIY repairs. Don't do it with springs. Springs are under extreme tension. A mistake can cause serious injury or property damage. Professional technicians have the right tools, experience, and insurance. We also guarantee our work.

How long does spring replacement take? Most spring replacements take one to two hours, depending on spring type and door condition. We aim for same-day completion whenever possible, minimizing your downtime.
Can I still use my garage door if one spring is broken? No. A broken spring removes counterbalance, making the door too heavy to lift safely. Operating it risks injury and damage to your opener. Wait for professional repair.
Do both springs need replacement at the same time? Usually yes. If one spring has failed, the other is near the end of its life. Replacing both ensures balanced operation and prevents a second failure weeks later.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly, stopping your door cold. A worn spring weakens gradually, making your door feel heavy or move slowly. Both need replacement, but worn springs give warning signs.
Are Boston winters really that hard on springs? Absolutely. Cold makes metal brittle, and salt air accelerates corrosion. Springs fail faster here than in milder climates. We've written extensively about this in our winter spring failure guide.
