In our 15 years serving Griswold homeowners, we've seen this problem again and again: a snapped garage door spring catches folks off guard, the door won't budge, and suddenly they're scrambling for answers. The good news is that understanding your spring type and replacement timeline prevents panic and saves money. Garage door springs come in two main styles, torsion and extension, and knowing which one you have determines both the repair approach and the cost estimate you'll receive.
Your garage door weighs between 300 and 500 pounds. Springs don't hold that weight up directly. Instead, they counterbalance it, making the opener's job manageable and keeping your door moving smoothly up and down. Without properly functioning springs, your opener works overtime, your door becomes a safety hazard, and your wallet takes a hit.
Springs typically last 7 to 9 years with regular use, though this varies based on how often you open and close your door. If you use your garage door five to eight times daily, expect springs to wear faster than someone who opens it twice a day.
Torsion springs sit above your garage door opening, horizontally across the top. They twist and unwind as your door moves, storing and releasing energy with each cycle. Most modern residential doors in Griswold use torsion springs because they're durable, precise, and safer than older extension spring setups.
Torsion springs come in various gauges and lengths depending on your door's weight and size. When one snaps, you'll hear a loud bang from the garage. Your door likely won't open, or it'll feel heavier than usual when you try the remote.
The advantage of torsion springs is their longevity and balance. A single snapped torsion spring usually means a full replacement of both springs (even if only one broke). This ensures even wear and prevents the door from operating unevenly. Learn more about spring replacement specifics in our detailed garage door spring replacement guide.
Extension springs run along each side of your door opening, inside the vertical tracks. They stretch and contract to provide counterbalance. Older homes and some budget installations still use extension springs, though they're less common in newer Griswold builds.
Extension springs are prone to more wear because they're constantly stretching. When one snaps, the other side still works, but your door becomes unbalanced and stresses your opener. Unlike torsion springs, extension springs sometimes allow you to replace just the broken one, though best practice is replacing both for safety.

Springs fail for predictable reasons. Metal fatigue is the main culprit. Each time your door cycles, the spring flexes. Over thousands of cycles, microscopic cracks form until the metal finally gives way. Rust accelerates this process, especially in Connecticut's humid climate and salt air near the coast.
Lack of maintenance speeds up failure too. A garage door that squeaks or moves unevenly puts extra stress on springs. Regular lubrication and tune-ups catch problems before they become expensive repairs. Our maintenance guide explains what actually prevents costly repairs and extends spring life significantly.
A same-day spring replacement estimate typically ranges from $250 to $400 per spring, depending on the type, length, and your door's weight. Torsion springs cost slightly more than extension springs, but the difference is minimal. Labor is usually the bigger cost factor, especially if you need same-day service.
Never attempt to replace springs yourself. The tension stored in a compressed spring can cause serious injury or death. This is one repair where hiring a professional near me isn't optional. It's essential.

How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with average daily use. Springs that cycle 5 to 8 times per day wear faster than those used twice daily. Proper lubrication and maintenance can extend lifespan slightly, but replacement is inevitable.
Can I replace just one spring? With torsion springs, both should be replaced together to ensure balanced operation and prevent uneven stress. Extension springs sometimes allow single replacement, but matching the new spring's tension to the old one's remaining strength is tricky. Professional installation ensures safety and proper function.
What's the difference between torsion and extension springs? Torsion springs twist above your door opening, while extension springs stretch along the side tracks. Torsion springs are more durable, precise, and safer. Most modern doors use torsion. Extension springs are older and more prone to sudden failure.
How much does spring replacement cost? Spring replacement typically runs $250 to $400 per spring plus labor. Full replacement of both springs in a two-spring system costs $500 to $800 installed. Same-day service may carry a small upcharge. Call for a free estimate specific to your door.
What should I do if my spring snaps? Stop using your garage door immediately. Don't force it open or closed. Call a professional for same-day repair. Attempting DIY spring replacement risks serious injury from stored tension. Contact us at 1-860-370-3986 for immediate assistance.
