Garage Door Springs in Dennis: Types, Costs, and When to Replace
2026-05-04 7 min read A2Z Garage Doors
Garage door springs are the hardest working part of your system, and they're usually the first thing to fail. There are two main types: torsion springs (mounted above the door) and extension springs (on the sides). Most Dennis homeowners have torsion springs, which last 7 to 9 years with normal use. A snapped spring means your door won't open or close safely, so knowing what to expect helps you avoid panic decisions and inflated repair bills.
Understanding Torsion vs. Extension Springs
Your garage door weighs 300 to 500 pounds. Springs counterbalance that weight so the opener doesn't burn out. Torsion springs are wound tight and mounted horizontally above the door opening. They twist to lift the weight. Extension springs hang beside the tracks and stretch as the door lowers. Torsion springs are more durable and predictable; extension springs wear faster and can snap suddenly if one breaks (the other can't handle the full load alone). See our guide on weather stripping & seals in dennis: stop drafts and energy loss today.
Torsion springs are standard in most modern garages because they're safer and last longer. If you have extension springs, replacement often means upgrading to torsion. That's a bigger upfront cost, but you'll save money over time through fewer repairs and longer intervals between replacements.
Why Springs Fail and How to Spot Trouble
Springs fail because of metal fatigue. Every open and close cycle stresses the coils. Salt air near Dennis accelerates corrosion, shortening lifespan significantly. If you notice your door opening slowly, hesitating midway, or making a loud bang when closing, those are red flags. A snapped spring usually produces a sharp crack sound, and the door becomes impossible to lift manually.
If you live near coastal areas in Massachusetts, check our guide on salt air damage to garage door hardware. Corrosion weakens springs faster than wear alone, so preventive maintenance matters more here than inland.

Cost Breakdown and What to Expect
A single torsion spring replacement typically costs between $150 and $300, depending on spring size and quality. Many homeowners think one broken spring is enough, but springs wear as a pair. Replacing both at once costs more upfront (usually $250 to $500 total) but prevents a second failure weeks later. That second failure often happens when you're unprepared, leading to emergency calls with rush fees.
Labor is usually $100 to $150 per hour. A spring replacement takes 1 to 2 hours for an experienced technician. If you need both springs and the door has other worn parts (like the cable or pulley), expect the estimate to climb. Always ask for an itemized quote before work begins.
Extension spring replacements run $100 to $200 per spring because they're simpler to install. But again, replace both if one has failed. Upgrading from extension to torsion springs costs $400 to $700 because it's more labor intensive and torsion springs themselves are pricier.
DIY vs. Professional Repair
Springs are dangerous. They hold enormous tension. A slip or miscalculation can cause serious injury. Torsion springs especially require special winding tools and knowledge of proper tension. We've seen DIY attempts end in hospital visits. Unless you're a certified technician with the right equipment, this isn't a save-money opportunity. The risk far outweighs the labor cost.
Our spring replacement service covers the full job, includes a warranty on parts, and guarantees safe installation. When you schedule a free quote, we'll inspect the entire system so no surprises appear mid-repair.
When to Call for Help
If your door won't open or close, stop trying to force it. A broken spring can't support the weight, and pushing the opener strains the motor. Call for same-day service. If the door is stuck open (a safety and security issue), don't wait. Spring failures often happen at the worst times.
Regular maintenance extends spring life. Lubricate the springs and hardware annually, inspect for rust or fraying cables, and keep the tracks clean. See our winter preparation guide for seasonal maintenance tips that prevent costly mid-season failures.

Frequently Asked Questions
How do I know if my garage door spring is broken? A loud bang or crack when operating, the door opening slowly or not at all, or the door slamming down hard are clear signs. You might also see the door hanging unevenly. Stop using it immediately and call for service.
Can I replace one spring if only one is broken? Technically yes, but replacing both is smarter. Springs wear as a pair. The surviving spring is already stressed, so replacing just one often leads to a second failure within weeks, meaning another service call and repair cost.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (roughly 10,000 to 15,000 cycles). Coastal salt air and heavy use reduce this timeframe. Extension springs usually fail sooner, often at 5 to 7 years.
What's the difference between emergency and standard spring replacement? Standard service is scheduled during business hours. Emergency service covers nights, weekends, and holidays with a rush fee (usually $50 to $100 extra). If your door is stuck, we prioritize same-day response.
Should I upgrade to torsion springs if I have extension springs? Yes, if one extension spring breaks. Torsion springs last longer, are safer, and prevent the catastrophic failure risk of extension springs. The upfront cost is higher, but you'll save money over the door's lifetime.
