Garage Door Springs in Woodstock, NH: Torsion vs. Extension Explained
2026-07-31 7 min read A2Z Garage Doors
There are two types of garage door springs: torsion and extension. Torsion springs sit above your door and twist to lift it. Extension springs run along the sides and stretch to do the job. Most modern homes in Woodstock use torsion springs because they're safer and last longer. Knowing which one you have matters when something breaks.
The Two Spring Types: What Sets Them Apart
Torsion springs wind tightly around a metal rod mounted horizontally above your garage door opening. When the door closes, springs store mechanical energy. That energy releases to lift the door smoothly when you open it. They typically last 7 to 9 years with normal use, handling roughly 10,000 to 15,000 cycles before wearing out.
Extension springs work differently. Mounted on each side of the door frame, they stretch as the door lowers. When you open the door, they contract and pull cables attached to the door panel. Extension springs have a shorter lifespan, usually 5 to 7 years, and they're more prone to sudden failure because all the stress concentrates on the springs themselves.
Torsion springs are the safer choice. When an extension spring snaps, the door can drop hard. Torsion springs fail more gradually, giving you warning signs before complete failure. If you're unsure which type you have, look above your door opening. A horizontal rod with coiled springs? That's torsion. Springs running along the side tracks? Those are extension springs.
Why Springs Fail: Cold Weather and Wear
Woodstock winters are brutal on garage doors. Metal contracts in subfreezing temperatures, placing extra stress on springs that are already under immense tension. A snapped spring in January isn't bad luck. It's the natural outcome of repeated freeze-thaw cycles working against aging metal.
Springs also fail simply from age. They're rated for a specific number of cycles. Once you hit that limit, failure is inevitable. You can't predict the exact moment, but you can recognize the warning signs: a door that moves slower than usual, loud banging or popping noises when opening, or visible gaps in the spring itself.
If you've experienced a snapped spring before, you know how inconvenient it is. The door won't budge. You can't get your car out. Calling for emergency repair becomes necessary. That's why regular maintenance matters. Learn what every homeowner should know about garage door maintenance in Woodstock to catch problems early.

Spring Replacement Cost: What to Expect
A torsion spring replacement typically costs between $200 and $400 per spring, including labor. Extension springs run slightly cheaper, usually $100 to $250 per spring. Most doors have two springs, so budget accordingly. If both springs are original and similarly aged, replacing both at once is smarter than replacing one now and the other in six months.
Labor dominates the cost because spring replacement requires specialized tools and expertise. A snapped spring carries stored energy that can cause serious injury if mishandled. This isn't a DIY job. Professional technicians have the equipment and training to do it safely.
When you call for an estimate, be specific about your door's age and the spring type you have. Different door sizes and weights require different spring specifications. Woodstock Garage Doors will assess your springs and give you a clear cost breakdown before starting work. No surprises. No pressure to replace parts you don't need yet.

Prevention: Making Springs Last Longer
You can't stop springs from aging, but you can slow it down. Keep your garage door balanced. An unbalanced door puts uneven stress on springs and wears them faster. Test this monthly by disconnecting the opener and manually lifting the door halfway. It should stay in place. If it drifts, call a technician.
Lubricate your springs twice yearly with a silicone-based garage door lubricant. This reduces friction and helps springs move smoothly. Don't use WD-40 or heavy oil. They attract dust and gum up the mechanism.
Clean debris from your door tracks. Dirt and leaves can bind rollers and force springs to work harder. A simple sweep takes minutes and extends component lifespan significantly.

When to Call a Professional
A snapped spring requires immediate attention. Don't try to open your door manually or force the opener. You risk damaging the door itself or hurting yourself.
If you hear loud bangs or notice the door opening unevenly, get it checked soon. These are early warning signs. Catching a failing spring before it breaks completely prevents emergency service calls and keeps your door functioning safely.
Woodstock homeowners should plan for spring replacement every 7 to 9 years. Mark it on your calendar or let us handle the reminder. Call 19787423397 or get a same-day estimate to schedule an inspection.
Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use, rated for 10,000 to 15,000 opening cycles. Extension springs wear faster, lasting 5 to 7 years. Frequency of use, climate, and maintenance affect actual lifespan.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if mishandled. Professional technicians have specialized tools and training required for safe replacement. Always hire a licensed repair service.
Why did my garage door spring break in winter? Cold metal contracts, placing extra stress on springs already under high tension. Freeze-thaw cycles weaken metal gradually. Springs that survive summer may fail suddenly when temperatures drop in Woodstock winters.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and completely. The door won't open at all. A worn spring fails gradually, showing signs like slower movement or uneven opening. Worn springs give you time to schedule replacement. Snapped springs require emergency service.
How much does spring replacement cost? Torsion springs cost $200 to $400 per spring including labor. Extension springs run $100 to $250 each. Most doors have two springs. Costs vary based on door size, spring type, and local labor rates in Woodstock and surrounding areas.
