Garage Door Springs in Marlow: Why They Fail and How to Avoid a Costly Mistake

2026-06-29 7 min read

A customer called last Tuesday with a dead garage door. She'd heard a loud bang that morning, and now the door wouldn't budge. The culprit: a snapped torsion spring. She'd been putting off maintenance for two years. A $150 annual inspection would have caught the wear early; instead, she faced a $500 repair bill plus a day without garage access. That's the difference between being proactive and reactive with garage door springs in Marlow.

What Are Garage Door Springs and Why They Matter

Your garage door weighs 300 to 500 pounds. Without springs, you couldn't lift it by hand. Torsion springs sit above the door and counterbalance that weight, making the opener's job effortless. Extension springs run along the sides and do similar work through a different mechanism. See our guide on garage door cost & pricing in marlow, nh: what you.

Both types fail eventually. Springs last 7 to 9 years under normal use, not 10 or longer. Every time your door opens and closes, the spring cycles. A spring rated for 10,000 cycles will wear out faster if you open your door five times daily versus twice daily. Temperature swings in New England also accelerate failure. Cold makes metal brittle; heat makes it expand and contract.

When a spring snaps, the door becomes a dead weight. You'll hear a loud crack or bang. The door might jam halfway up, or it might fall suddenly (dangerous for fingers and cars). This is why a snapped spring is an emergency, not a "call when you get time" problem. Read about preparing your garage door for hot weather: essential tips.

Common Causes of Spring Failure

Wear and age. Most springs fail simply because they've done their job thousands of times. No maintenance can extend their life indefinitely.

Lack of lubrication. Springs need annual lubrication to reduce friction and metal fatigue. Dry springs break sooner. A quick spray of garage door lubricant costs $10 and takes five minutes. Skipping it can shorten spring life by a year or more.

Rust and corrosion. Marlow winters bring salt air and moisture. If your garage isn't sealed well, rust eats away at spring metal from the inside out. This weakens the spring's structural integrity and leads to premature failure.

Poor installation. If springs aren't properly wound or balanced during installation, they'll fail years earlier than they should. This is why buying the cheapest service isn't always the budget-conscious move.

Extreme temperature swings. Metal contracts in cold and expands in heat. Repeated cycles stress the spring. New Hampshire's freeze-thaw cycles are especially hard on garage doors; our guide on winter garage door problems in Marlow) covers this in detail.

How to Prevent Spring Failure and Save Money

The best defense is routine maintenance. Schedule an annual inspection before winter arrives. A technician will check spring tension, look for rust, lubricate moving parts, and spot early wear signs. This costs under $150 and often prevents a $400+ repair.

Don't ignore warning signs. If your door opens slowly, closes unevenly, or feels heavier than usual, springs may be weakening. Address it before they snap. Same-day service is possible if you call early in the day, but waiting until the door fails limits your options.

Keep your garage reasonably dry. Seal gaps around the door frame and apply weather stripping where needed. We've written about weather stripping and seals in Marlow) if you want to learn how drafts signal bigger seal problems.

Spring Repair vs. Replacement: What's the Right Call?

If one spring is damaged, both should be replaced at the same time. Springs are a matched pair. If the left one just failed, the right one is near the end of its life too. Replacing only one means the other will snap weeks or months later, costing you twice.

The cost of replacing both torsion springs typically ranges from $300 to $600, depending on door size and spring quality. An extension spring replacement is usually $200 to $400. Get a free estimate before committing. We can schedule a free quote) and provide a transparent breakdown.

Frequently Asked Questions

How much does a garage door spring replacement cost near me? Torsion spring replacement typically costs $300 to $600 for both springs. Extension springs run $200 to $400. Cost varies by door size, spring quality, and local labor rates. Call (978) 721-5664 for a free estimate specific to your Marlow home.

Can I replace just one garage door spring? You can, but you shouldn't. Springs are sold and rated as pairs. If one fails, the other is near failure too. Replacing only one means a second emergency call within weeks. Replace both at once and you avoid this hassle.

How long do garage door springs last? Most springs last 7 to 9 years with normal use (one to three cycles daily). Springs rated for 10,000 cycles will wear faster if your door cycles five or more times daily. Annual maintenance can help them reach their rated lifespan but won't extend it indefinitely.

What does a snapped garage door spring sound like? A loud bang or crack, like a gunshot inside your garage. Some people describe it as a metallic pop. If you hear this sound, don't try to open or close the door. Call for professional help immediately.

Why do garage door springs fail in winter? Cold temperatures make metal brittle and reduce lubrication effectiveness. New England's freeze-thaw cycles stress springs repeatedly. Salt air and moisture accelerate rust. Marlow winters are particularly hard on garage doors, which is why pre-winter maintenance is critical.
