Here's what most homeowners don't realize about garage door springs: not all springs are the same. Your garage door uses either a torsion spring or extension springs, and misidentifying which one you have can lead to wrong repair estimates, safety risks, and unnecessary overspending. Knowing your spring type takes 30 seconds and could save you hundreds on your next service call in Norwalk.
Your garage door weighs between 300 and 500 pounds. Two small metal coils hold that entire weight in balance. When you press the opener button, those springs do the heavy lifting, not your motor.
A torsion spring is a single coil mounted horizontally above your garage door opening. It twists (torques) as your door moves up and down. Most modern homes built after 1990 use torsion springs because they're safer, quieter, and last longer (typically 7 to 9 years with regular use).
Extension springs run vertically along both sides of your door frame. They stretch and contract like rubber bands. Older homes and some budget installations use extension springs. They tend to fail faster and require safety cables to catch a broken spring before it snaps toward your face.
To spot which type you have, look directly above your closed garage door. See a single horizontal coil? That's torsion. See two springs running up the sides of the frame? Those are extension springs.
Torsion and extension springs have different replacement costs. Torsion springs typically run $200 to $400 per spring in Norwalk, while extension springs cost $100 to $200 each. But here's the budget catch: if you have extension springs, you should replace both at the same time, even if only one snapped. One old spring will fail within months, forcing you back to square one.
Our team at Garage Door Norwalk sees homeowners delay repairs because they don't understand their spring type. A snapped torsion spring means your door likely won't open at all. A snapped extension spring might let your door move, but unevenly, straining your garage door opener and inviting more expensive damage down the road.
Learn why snapped springs happen and what replacement actually costs so you're not shocked at the service counter.

Both spring types are rated for a specific number of cycles (open/close cycles). Most residential springs handle 10,000 cycles. If your family opens the door twice daily, that's roughly 7 to 9 years of life. Homes in coastal areas like Long Beach face faster corrosion, cutting that window to 5 to 7 years.
You can't prevent spring failure. It's not a maintenance issue. Springs wear out like brake pads, not because you neglected them. However, regular garage door maintenance catches warning signs early. Unusual noise, jerky movement, or sagging sections tell you a spring is nearing the end.
Follow our maintenance checklist to spot early warning signs before a spring snap leaves you stuck in your driveway.

Some homeowners consider replacing springs themselves after watching YouTube videos. Don't. Torsion springs carry enormous tension. A slip, a wrong tool, or one miscalculation can send a spring or rod through your hand, your face, or your chest. Hospital visits aren't budget-friendly.
Extension springs are slightly safer to handle, but safety cables can snap unexpectedly. Leave spring replacement to trained technicians with proper tools, insurance, and liability coverage. The money you "save" isn't worth the risk.
Your garage door spring type shapes your repair cost, timeline, and safety strategy. Torsion springs are common in newer homes and cost more upfront but last longer. Extension springs are cheaper but fail faster and require dual replacement.

How do I know if my spring is torsion or extension? Look above your closed garage door. A single horizontal coil is torsion. Two springs running vertically on each side are extension. If you can't see clearly, a technician can confirm in seconds.
Can I replace just one extension spring? Technically yes, but it's wasteful. The remaining spring will fail within months since springs wear evenly. Replace both at once to avoid a second service call and labor charge.
How much does spring replacement cost in Norwalk? Torsion springs run $200 to $400 each. Extension springs cost $100 to $200 each, but buy two. Labor typically adds $150 to $250. Call for a free quote with no obligation.
Do garage door springs need maintenance? Springs themselves don't need maintenance. They wear out naturally. Regular lubrication and inspection of other door components prevent secondary damage and extend overall door life.
How long do garage door springs last? Most springs handle 7 to 9 years of typical use (opening twice daily). Coastal humidity or extreme use shortens lifespan. Your springs are on borrowed time after year 10.
