If your garage door won't open or you hear a loud bang from above, a snapped spring is almost certainly the culprit. Garage door springs in Plaistow fail more often than homeowners expect, especially in New England's freeze-thaw cycles. This guide explains what's actually happening, when a repair makes sense versus full replacement, and what the real cost looks like.
Your garage door weighs 300 to 500 pounds. Two springs, typically torsion or extension types, counterbalance that weight so your opener doesn't strain. Springs last 7 to 9 years under normal use, but temperature swings in Plaistow and southern New Hampshire accelerate wear. Metal contracts in freezing mornings, expands in afternoon sun, and that cycle weakens the steel.
When a spring finally snaps, the door becomes unsafe. It won't open smoothly, and the door itself can drop suddenly. Extension springs sit along the sides of the door track. Torsion springs mount horizontally above the door opening. Both types store enormous tension, so this isn't a DIY repair. A snapped spring needs professional attention, period.
If only one spring is broken and the other is still functional, repair is tempting. You replace the bad spring, adjust the tension, and move on. That costs less upfront. But here's the craftsman's truth: when one spring fails after 7 to 9 years, the other one is nearing the same breaking point.
Replacing both springs at once costs more initially, but it saves you a second service call in six months. You're not paying for a technician to return, and you're not risking a second failure when you least expect it. Most Plaistow homeowners find that replacing both springs, done right the first time, makes more sense than a quick patch.

Spring replacement isn't cheap, but it's not hidden either. A single torsion spring runs roughly 150 to 300 dollars. An extension spring costs slightly less. Labor for a professional to remove the old spring, install new ones, and properly tension them adds another 200 to 400 dollars depending on the job's complexity.
Total estimate for both springs, installed: 600 to 1000 dollars. That's for quality springs and careful work. Cheaper springs exist, but they wear out faster. We source springs built to last, not just to look cheap on the invoice.

Emergency calls cost more because same-day availability commands a premium. A snapped spring at 7 p.m. on a Saturday will cost more than scheduling it for a Tuesday morning. But if your door is stuck and you need to get your car out or secure your garage, that premium is worth it.
Listen for a loud bang or crack from your garage. That's the sound of a spring snapping under load. If your door opens unevenly, sagging on one side, a spring is weakening. The door feels heavier to open, even with the opener. Your remote works, but the door barely moves.
Any of these warrant a free estimate. We'll inspect both springs, check the cable for damage, and tell you exactly what needs to happen. No surprises, no upselling. Just the work the door actually needs.

A spring under tension can cause serious injury if it releases unexpectedly. The tools needed (tension wrench, proper support equipment) aren't standard homeowner gear. A professional knows how to safely release tension, remove the old spring, and install and adjust the new one so the door opens and closes smoothly.
We also check your cable, lubricate the track, and make sure your opener isn't working harder than it should. A thorough spring job includes the whole system, not just swapping parts.

The cost of waiting for springs to fail catastrophically always exceeds the cost of preventive replacement. If your door is over 7 years old and you haven't replaced the springs, now is the time to act. Call us at (978) 953-8904 to schedule a free inspection, or visit our springs service page to learn more.
How long do garage door springs typically last? Most springs last 7 to 9 years with normal use. New England winters shorten that lifespan. Regular lubrication and inspection help springs reach their full life expectancy.
Can I replace just one spring? You can, but we don't recommend it. The second spring is likely near failure too. Replacing both at once costs more upfront but prevents a second emergency call and saves labor fees.
What's the difference between torsion and extension springs? Torsion springs mount above the door and rotate to lift it. Extension springs sit along the tracks and stretch to pull the door up. Torsion is more durable and safer for most residential doors.
How much does spring replacement cost near me? In Plaistow, expect 600 to 1000 dollars for both springs installed. Single spring replacement runs 350 to 600 dollars. Same-day emergency service costs more than scheduled appointments.
Why do springs fail faster in winter? Cold metal becomes brittle. Temperature swings in New England cause expansion and contraction that weakens steel over time. Salt air near the coast accelerates corrosion too.
