A customer called last Tuesday morning, panic in her voice. Her garage door wouldn't close, and she'd heard a loud bang the night before. I knew immediately: snapped torsion spring. She'd been considering a DIY fix. I'm grateful she called first instead of attempting it herself. That's the conversation I want to have with every homeowner in Cohasset facing a failing garage door spring.
Garage door springs aren't glamorous, but they're working overtime every single day. A typical spring completes roughly 10,000 to 15,000 cycles before failure. Each cycle is one complete open and close. Most springs last between 7 and 9 years, depending on climate, usage, and maintenance.
Here on the South Shore, our saltwater air accelerates rust formation. Springs corrode faster near the coast. Metal fatigue compounds the problem. Tiny stress fractures develop invisibly over months. Then one morning, you hear that violent snap, and the door either slams down or won't budge.
The two main types are torsion springs, which wind above the door, and extension springs, which run along the sides. Torsion springs are stronger but more dangerous to handle. Extension springs fail less spectacularly but still leave you stranded.
This is where I need to be blunt. A snapped spring transforms your garage door into a 300-pound liability. The door loses all counterbalance. It becomes a crushing hazard for fingers, hands, and small children. Your garage door opener will strain harder than ever designed, potentially burning out the motor or stripping the chain.
Attempting a DIY replacement can result in serious injury or death. Springs carry extreme tension. If one end slips while you're working, the spring can snap outward with enough force to break bones or cause lacerations. I've seen photos from other regions where this went wrong. Don't let that be you.
Even a partial DIY attempt, like loosening bolts or trying to adjust tension, creates risk. The correct tools (winding bars, safety cables) cost hundreds and require training to use properly. That's why Cohasset Garage Doors always recommends calling a licensed technician for spring work.
If your door is operating normally but you suspect aging springs, you have options. We cover the repair versus replace decision in detail on our guide to repairing or replacing garage door springs in Cohasset. The short version: if your springs are over 7 years old and showing wear, replacement is safer than patching.
If you hear creaking, see visible rust, or notice the door rising unevenly, replacement is the answer. Both springs should be replaced together, even if only one failed. The other is likely near the end of its life too.

The cost of spring replacement varies based on spring type, door size, and whether you need one or both springs replaced. We provide free estimates for all spring work. A professional assessment takes 15 minutes and gives you complete transparency on pricing and timeline.
Don't assume all spring replacements cost the same. Torsion springs are more expensive than extension springs but last longer and perform better. A 16-foot commercial door needs heavier springs than a residential 7-footer. The estimate accounts for these factors.

You can't stop springs from aging, but you can slow the process. Regular lubrication reduces friction and rust formation. Inspect your springs twice yearly, especially before winter and after coastal storms. Look for visible rust, uneven gaps, or any signs of wear.
Keep the garage clean and dry when possible. Moisture accelerates corrosion. If you notice anything unusual, don't wait for a complete failure. A small investment in preventive maintenance saves the cost and hassle of emergency replacement.

A working garage door is a safety feature, not a convenience. Don't let a failing spring put your family at risk.
How do I know if my garage door spring is broken? Listen for a loud bang or snap when the door opens or closes. If the door won't open, opens partially, or moves unevenly, the spring has likely failed. Do not force the door open with the opener.
Can I replace a garage door spring myself? Absolutely not. Springs carry extreme tension and can cause serious injury or death if handled incorrectly. Always hire a licensed technician for any spring work, no exceptions.
How much does a garage door spring replacement cost near me? Residential spring replacement typically ranges from $200 to $400 per spring, depending on type and door size. A professional estimate is free and takes 15 minutes. Call us for pricing details.
How long do garage door springs last in Cohasset? Most springs last 7 to 9 years with normal use. Coastal salt air accelerates corrosion, so South Shore springs may fail sooner. Annual inspections catch wear before failure.
Do both springs need to be replaced at the same time? Yes. If one spring fails, the other is near failure too. Replacing both ensures balanced performance and prevents a second emergency repair within months.
