Garage Door Springs in Truro: Torsion vs. Extension and When to Call
2026-05-24 7 min read A2Z Garage Doors
After 15 years on garage door trucks across the Cape, I've seen every spring failure you can imagine. Let me cut through the confusion about garage door springs in Truro. The short answer is this: your door uses either a torsion spring or extension springs, they wear out around 7 to 9 years, and a snapped spring means your door won't open safely until it's replaced.
Understanding Spring Types
Most homes in Truro have one of two setups. Torsion springs sit above the door opening on a horizontal rod. They twist and unwind to lift the door's weight. Extension springs run along the sides of the opening and stretch to do the same job.
Torsion springs are stronger and last longer, typically 7 to 9 years with normal use. They're also safer because they're enclosed. Extension springs are cheaper upfront but wear faster, especially in our salty coastal air. If you live near the water here in Truro or out toward Dennis or Wellfleet, corrosion speeds up failure in both types.
You'll know which you have by looking. Torsion springs look like a thick metal coil above the door. Extension springs look like long coils running horizontally on each side of the opening. Don't touch either one. The tension is enormous and can cause serious injury.
Why Springs Fail
Springs don't just break randomly. They fail because of wear cycles. Every time your door opens and closes, the spring works. A typical spring handles 10,000 to 20,000 cycles before it's done. If you open your door four times a day, that's roughly 7 to 9 years.
Salt air corrodes them faster. Our moisture and salt spray weakens the metal from the outside in. That's why I see more spring failures in Truro than in inland towns. Poor maintenance makes it worse. A spring that never gets lubricated or inspected wears unevenly and snaps sooner.
One common mistake: ignoring the warning signs. If your door sounds louder than usual, moves slowly, or hangs unevenly, the spring is weakening. Read our post on garage door spring warning signs every Truro homeowner should recognize for the full checklist.
Repair vs. Replacement Cost
A snapped spring means replacement, not repair. The cost depends on which type you have and whether you need one or both springs replaced. Torsion springs run between $200 to $400 per spring, plus labor. Extension springs are cheaper, around $150 to $250 each. Labor usually adds another $150 to $300.
If both springs are original and roughly the same age, I always recommend replacing both at once. One fails, the other won't be far behind. You'll save money and frustration by doing it right the first time. For a detailed cost breakdown, check out our repair cost breakdown guide.

What to Do When a Spring Snaps
If you hear a loud bang and your door won't open, that's a snapped spring. Don't force it. A broken spring means the opener is working alone against the full weight of the door. You risk burning out the motor or damaging the door itself.
Call a professional right away. We can usually get to same-day appointments for spring breaks. While you wait, use the manual release handle inside the garage if you need to open the door by hand. Pull down the red cord attached to the opener carriage. Lift slowly and carefully.
This is also a good time to have your entire system inspected. A broken spring often means worn rollers, a tired opener, or other issues hiding underneath. Our team can schedule a free quote and walk you through all the repairs you actually need, not just the obvious one.
Prevention and Maintenance
You can extend spring life with basic care. Keep the springs and rollers lubricated with garage door lubricant (not WD-40). Inspect them twice a year, especially after winter and before summer. Look for rust, fraying, or uneven wear.
If you live in Truro or nearby areas like Yarmouth or Orleans, consider our preventive maintenance service. We'll catch weak springs before they snap. We also help with seasonal prep. Check out preparing your garage door for winter for tips on protecting your system year-round.
Springs are the hardest-working part of your garage door. Treat them with respect and they'll last their full lifespan. When they fail, don't delay. A broken spring strands your car and puts strain on everything else.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years under normal use. Extension springs wear faster, often 5 to 7 years. Salt air and humidity near Truro accelerate wear. Regular lubrication can extend lifespan slightly, but replacement is inevitable.
Can I replace a garage door spring myself? No. Springs carry extreme tension. A mistake during removal or installation can cause serious injury or death. Always hire a licensed technician. Professional replacement is safe, quick, and includes a warranty on parts and labor.
What's the difference between torsion and extension springs? Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch. Torsion springs are stronger, last longer, and are safer because they're enclosed. Extension springs are cheaper but more prone to failure and injury if they snap.
How much does a garage door spring replacement cost in Truro? A single torsion spring replacement runs $300 to $700 installed. Extension springs cost $250 to $550 installed. If both springs need replacement, expect $500 to $1,400 total. Call (508) 318-7015 for an exact estimate on your setup.
What happens if my garage door spring breaks? The door becomes extremely heavy and won't open safely. The opener may burn out trying to lift it alone. Stop using the door immediately and call a professional for same-day repair. Never try to force the door open or fix the spring yourself.
