A customer called last Tuesday with a problem we hear often: her garage door wouldn't budge, and she heard a loud crack from the garage that morning. A snapped torsion spring. Garage door springs in Plaistow fail without warning, usually after years of opening and closing cycles. When they break, your door becomes a 400-pound weight no opener can lift. This post explains why springs snap, what repair costs actually run, and how to avoid being stranded.
Garage door springs are engineered to handle roughly 10,000 to 15,000 cycles before wearing out. One cycle equals one full open and close. Most homeowners expect springs to last 7 to 9 years, though heavy use or poor maintenance can shorten that window significantly.
Springs fail for three main reasons. First, metal fatigue. Every time your door moves, the spring stretches and contracts under tremendous tension. Over time, tiny stress cracks form inside the metal. Eventually, those cracks split wide open. Second, rust and corrosion weaken the spring from the inside out, especially in New England where salt and moisture are constant threats. Third, lack of lubrication increases friction, forcing the spring to work harder than it should.
There are two types of springs: torsion and extension. Torsion springs sit above your garage door and twist to lift the weight. Extension springs run along the sides and stretch to help lift. Both types fail the same way. A snapped torsion spring typically makes a loud bang that sounds like a gunshot. Extension springs fail more quietly but leave your door sagging on one side.
A single snapped spring usually means you're looking at a repair bill of $200 to $400 for parts and labor. If both springs have failed (which happens), expect closer to $400 to $600. The actual cost depends on spring quality, your door's weight, and whether you choose same-day service versus scheduling ahead.

Many homeowners assume they need only one spring replaced. That's a mistake. Springs are designed to work as a pair, and if one has snapped, the other is near the end of its life. Replacing just one leaves you vulnerable to another failure in weeks or months. A proper repair involves replacing both springs at once. This costs more upfront but prevents a second emergency and saves money long term.

If your spring snaps, stop using your garage door immediately. Do not try to force it open or closed. A broken spring means the door is no longer balanced, and forcing it risks serious injury or damage to your opener. Call a professional right away. Same-day service is often available for emergencies like this across Plaistow and surrounding communities.
While you wait, park outside if possible. Your garage door will not open, and that's the correct response. Trying to operate it without a functioning spring can cause the opener motor to burn out, turning a $300 spring repair into a $600 opener replacement.
The best way to avoid a snapped spring is regular maintenance. Lubricate your springs and tracks every three months with a garage door specific lubricant. This reduces friction and extends spring life by years. Inspect springs visually for rust, gaps, or visible damage during your seasonal maintenance checks. If you spot rust, treat it immediately.
Our seasonal maintenance checklist for New England homes covers spring care in detail and helps you catch problems before they become emergencies.
Professional inspections also matter. A technician can measure spring tension, spot early wear, and recommend replacement before failure occurs. We offer free estimates and can schedule routine maintenance to keep your springs healthy. Contact us to schedule a free quote and protect yourself from surprise repairs.
Cold temperatures in Plaistow make springs more brittle. Metal contracts in freezing weather, and springs already weakened by age or corrosion become more prone to sudden failure during winter months. If you live in the area and haven't serviced your springs in over a year, now is the time to have them checked. An ounce of prevention during fall saves you from being locked out when temperatures drop.

How much does it cost to replace a snapped garage door spring? A single snapped spring costs $200 to $400 to repair. Replacing both springs (the smart choice) runs $400 to $600 depending on spring type, door weight, and labor. Emergency same-day service may add a small surcharge.
Can I open my garage door if the spring is snapped? No. Do not attempt to open or close the door. A broken spring leaves the door unbalanced and dangerous. You risk injury, damage to the opener, and further damage to the door itself.
How long do garage door springs last? Most springs last 7 to 9 years under normal use, rated for 10,000 to 15,000 cycles. Heavy use, poor lubrication, rust, and extreme temperatures can reduce lifespan significantly.
What's the difference between torsion and extension springs? Torsion springs twist above the door to lift weight. Extension springs stretch along the sides. Both fail similarly, but torsion springs are more common on residential doors and generally more durable.
Can I replace just one broken spring? Technically yes, but we don't recommend it. Springs work in pairs and wear at similar rates. Replacing only one leaves the other near failure, causing another emergency soon after.
