Garage Door Springs in Rindge: Torsion vs. Extension (And Why It Matters)
2026-06-22 7 min read
Your garage door springs are the hardest working part of your entire system, yet most homeowners have no idea which type they own. Torsion springs and extension springs do the same job (lifting a 300-400 pound door), but they work differently and cost different amounts to replace. Knowing the difference saves you money when a spring snaps.
Why Your Garage Door Springs Matter More Than You Think
Springs carry almost all the weight of your door. Your opener motor actually lifts only about 10 percent of that load. When a spring fails, your door becomes a 400-pound paperweight. A snapped spring isn't just inconvenient. It's dangerous. Doors without working springs can fall unexpectedly or jam, trapping a car or worse. That's why understanding your spring type isn't optional.
Most garage doors fail between 7 and 9 years of use. If your door is older, springs are probably next on the failure list. Acting before they snap means avoiding emergency calls and inflated pricing.
Torsion Springs: The Standard for Modern Doors
Torsion springs sit horizontally above your door opening. They twist (torsion) as your door opens and closes, storing and releasing energy. Nearly all residential doors built after 1980 use torsion springs, and for good reason: they're safer, quieter, and last longer than older extension designs.
One torsion spring can support your entire door weight. Many doors have two springs for added safety, so one can fail without the door crashing down. Rindge homeowners with mid-range or newer doors almost certainly have torsion springs.
The tradeoff: torsion springs cost more to replace (usually $250 to $400 per spring, installed) because they require precise balancing during installation. A tech needs special tools and skill to wind them safely. Doing this yourself risks serious injury.

Extension Springs: Older but Still Around
Extension springs hang on both sides of your door, running along the tracks. As your door lowers, they stretch (extend). As it rises, they contract and help lift. They're less common now but you'll still see them on older garages in the Rindge area and throughout southern New Hampshire.
Extension springs are cheaper upfront (about $150 to $250 each), but they fail faster (typically 5 to 7 years) and require safety cables to prevent injury if they snap. If one extension spring breaks, both usually need replacement soon after because they wear evenly.
The Cost Reality: Don't Overpay for a Snapped Spring
A snapped spring is the most common garage door failure we see. The temptation to call the first contractor is strong. But a quick phone call asking the right questions saves hundreds.
Before you book, ask: What type of springs do you have? How many? Some companies will quote you a high price assuming both springs need replacement when only one is truly worn. If you've had your door for 8 or 9 years, replacing both makes sense. If one is newer, ask about replacing only the failed one (though you'll likely see the second fail within months).
Our guide on getting an honest garage door repair estimate in Rindge walks through questions to ask any contractor before they charge you for a service call. It also covers what a fair estimate looks like so you're not caught off guard.
When to Replace Springs Yourself (Spoiler: Rarely)
Spring replacement is one of the few garage door jobs you should never DIY. Springs are under extreme tension. Incorrect winding or installation can send a metal coil flying at dangerous speeds. Hospitals see spring-related injuries every month. The $200 to $400 you might save isn't worth a trip to the ER.
If your budget is tight, focus on preventive maintenance instead. Regular tune ups (about once a year) can extend spring life by 1 to 2 years. Check out our post on garage door maintenance in Rindge for affordable ways to keep springs healthy longer.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use (about 3 to 5 cycles per day). Extension springs fail faster, usually at 5 to 7 years. Climate, humidity, and frequency of use affect lifespan.
Can I replace just one spring? Yes, but both springs wear evenly. If one has failed after 8 years, the other is close behind. Many contractors recommend replacing both to avoid a second failure within weeks.
Why is spring replacement so expensive? Torsion springs require specialized tools, precise balance calculations, and safety training. Installation is hazardous without proper equipment. Labor and expertise make up most of the cost, not the part itself.
What's the difference between torsion and extension springs? Torsion springs twist horizontally above the door. Extension springs stretch vertically along the tracks. Torsion is safer, lasts longer, and is standard on modern doors. Extension is older but cheaper upfront.
Is a snapped spring an emergency? Yes. A broken spring means your door won't open or is unsafe to operate. Call a professional immediately. Attempting to use the door risks injury or further damage to the opener and tracks.
