Garage Door Springs in Plymouth, NH: What You Need to Know Before They Snap
2026-08-03 7 min read
Here's what most homeowners don't realize about garage door springs: they carry roughly 400 pounds of tension and do 80% of the heavy lifting when your door opens or closes. Your garage door opener only helps guide the door. When a spring fails, your entire system becomes a safety hazard and a very expensive repair. I've been pulling trucks to Plymouth homes for 15 years, and I can tell you that spring failures are the single most common call I get.
Why Garage Door Springs Matter More Than You Think
Your garage door weighs between 300 and 500 pounds depending on the style and material. That's not something you want crashing down on your car, your kid's bicycle, or worse. Springs exist to balance that weight and make the door manageable. See our guide on when to replace weather stripping & seals on your plymouth garage door.
There are two main types: torsion springs and extension springs. Torsion springs sit above your door on a metal rod and twist to lift the weight. Extension springs run along the sides of the door and stretch as it opens. Most modern homes in New Hampshire use torsion springs because they're safer and last longer. Torsion springs typically last 7 to 9 years with normal use, while extension springs often give out sooner.
When a spring snaps, you'll hear a loud bang or crack. Don't ignore it. A snapped spring means your door won't open smoothly, and the opener will work twice as hard trying to compensate. That extra strain damages the opener motor and tracks. Read about garage door openers in plymouth, nh: which one really fits your home?.
The Cost of Waiting Too Long
Spring replacement costs vary, but you're looking at $150 to $400 per spring depending on the type and how many need replacing. Most doors have one or two springs. If you catch the problem early and replace one spring, that's one estimate. If you wait until both snap or the opener gets damaged, your cost doubles or triples.
I always recommend calling for a free estimate as soon as you notice any of these warning signs: the door moves slowly, it hangs unevenly, or you hear creaking sounds. A professional can diagnose the problem and give you an honest cost breakdown before any work begins. Plymouth Garage Doors offers same-day service for spring emergencies, and we'll walk you through your options without pressure.

Spring Maintenance Keeps Your Door Running Longer
The best defense is regular maintenance. Springs don't need much, but they do need attention. Lubricate them twice a year with a silicone-based spray. Don't use WD-40 or general-purpose oils because they attract dirt and gum up over time. A light coating keeps the metal moving smoothly and reduces wear.
Also, pay attention to your garage door's balance. If the door feels heavy or tilts to one side, that's a sign the springs are weakening unevenly. Check out our complete tune-up guide for garage door maintenance in Plymouth to see what else you can do between professional visits.
One more thing: never attempt to replace or adjust garage door springs yourself. I've seen too many injuries from DIY attempts. Springs are under extreme tension, and if you slip or misjudge the release, you could break a hand or worse. This is a job for someone with the right tools and training.
When to Call for Help
If you notice your door acting strange, contact a professional right away. A snapped spring won't fix itself, and waiting puts unnecessary stress on your opener and the rest of the system. We can schedule a free quote and get your door back in service the same day in most cases.
The biggest mistake homeowners make is thinking a spring problem will go away. It won't. Springs are load-bearing components, and once they start to fail, the failure accelerates. Catch it early, and you save money.
