Extension vs. Torsion Springs in Sandwich, NH: Which Should You Replace?

7 min read

A customer called last Tuesday asking whether her garage door needed extension springs or a torsion spring replaced. She'd been quoted $800 by another shop and wanted to know if that price made sense. The answer depends on which type your door actually uses, how old the springs are, and whether both need replacement at once. Most homeowners don't realize these two spring types serve the same job but fail differently and cost differently to fix.

What's the Difference Between Extension and Torsion Springs?

Torsion springs wind tightly above your garage door opening and store energy by twisting. They're stronger, last longer (typically 7 to 9 years with normal use), and support most of the door's weight. One snapped torsion spring usually means the other will fail soon after since they work together. That's why we always recommend replacing both at the same time, even if only one has snapped.

Extension springs run horizontally along the sides of your door's tracks. They stretch and contract to lift the door, and they wear out faster than torsion springs, usually lasting 5 to 7 years. Because there are two of them working independently, you might replace just the broken one. However, if one fails, the other is likely stressed and ready to snap, so replacing both makes budget sense.

Torsion springs handle significantly more load and tension. That's why they cost more to replace but save money over time. Extension springs are cheaper upfront but may need attention sooner. Learn why your spring snapped and what repairs actually cost to understand the full picture of replacement budgets.

Which Type Does Your Door Have?

Look above the door opening, not along the sides. If you see a thick metal shaft with springs coiled around it, you have torsion springs. If springs run along each side of the track near the floor, those are extension springs. Take a photo and text it to us at 19789568574 if you're unsure. Many homeowners guess wrong and get quoted for the wrong repair.

Your garage door's age and weight also affect which type was installed. Heavier doors almost always use torsion springs. Lighter residential doors can work with either system, though torsion is more common in newer construction. If you've had your door for 15+ years and it still opens smoothly, the springs have likely been replaced already. That's actually a good sign the door was maintained properly.

Why Spring Failure Timing Matters for Your Budget

A snapped spring won't let your door open or close safely, even if you have an opener with backup power. The door becomes a 300 to 400 pound dead weight. That's why same-day service matters when springs fail. Waiting even a few days means your car stays trapped or your garage stays inaccessible.

The cost estimate you receive depends on a few variables. Torsion spring replacement runs higher because the job requires more precision and specialized tools. Extension spring replacement is typically less expensive but may need to happen twice in the span of time one torsion spring lasts. Our honest pricing guide shows what factors change your quote and why two shops might quote differently for the same job.

Preventative maintenance catches wear before springs snap. A tune-up every 12 months costs less than emergency repair and replacement. Lubrication, track alignment, and spring tension checks add years to spring life. If you haven't had maintenance done in over two years, a spring failure is statistically closer than you think.

Getting the Right Estimate

Don't rely on phone quotes alone. A technician needs to see your door's weight, spring type, and current condition to give an accurate price. Some shops charge extra for same-day service or after-hours calls, even in Sandwich and nearby towns. Ask upfront whether the estimate includes labor for both springs, hardware replacement, and any adjustments needed to the door's balance afterward.

Frequently Asked Questions

How long do garage door springs typically last? Torsion springs last 7 to 9 years with normal use (roughly 10,000 cycles). Extension springs fail sooner, usually within 5 to 7 years. Lifespan depends on door weight, frequency of use, and maintenance. Regular lubrication extends spring life.

Can I replace just one spring instead of both? With torsion springs, no. Both should be replaced together because they share the load. If one has snapped, the other is stressed and will fail soon. With extension springs, you can replace one, but replacing both costs only slightly more and prevents a second service call.

What does a garage door spring replacement cost near me? Extension spring replacement typically ranges from $200 to $350 per pair. Torsion spring replacement costs $300 to $500 or more depending on door weight and spring quality. Emergency or same-day service adds $50 to $150. Request a specific estimate rather than relying on price ranges.

Is a snapped garage door spring an emergency? Yes. A broken spring makes the door unsafe to operate and may damage the opener if forced. The door could drop unexpectedly. Call for same-day service. Don't attempt DIY repair.springs are under extreme tension and cause serious injury.

Why do both springs fail at the same time? They don't always fail simultaneously, but they wear evenly because they lift the same load. When one snaps suddenly, it signals the other is near failure. Replacing both avoids a second emergency call within weeks and ensures balanced door operation.
