After 15 years crawling under garage doors in Proctorville and across the foothills, I've seen homeowners get blindsided by spring problems simply because they didn't know which type they had. The truth is straightforward: two main spring designs power almost every residential garage door. Understanding the difference between torsion and extension springs saves you money, prevents injuries, and helps you make smarter repair decisions.
Torsion springs sit horizontally above your garage door opening, mounted on a steel rod. When you open the door, these springs twist (that's where "torsion" comes from) and store energy that helps the opener lift the weight. When you close it, that stored energy lowers the door smoothly.
Here's why they matter: torsion springs carry about 80 percent of the load. The garage door opener only does 20 percent of the work. That's why a snapped torsion spring means your door won't budge, even with a functioning opener. Most modern homes in Proctorville use torsion springs because they're safer, last longer (typically 7 to 9 years), and don't take up wall space like extension springs do.
The downside? Torsion springs cost more to replace than extension springs, and the installation requires knowledge and specialized tools. This isn't a DIY job. A wound spring under tension can cause serious injury or death if it slips.
Extension springs run along both sides of your garage door opening, above the horizontal tracks. When the door opens, these springs stretch. When it closes, they contract and help pull the door down. They're called "extension" because they extend and retract.
You'll find extension springs more often in older homes and some budget installations. They cost less upfront and take up more space. The trade-off: they don't last as long as torsion springs (usually 5 to 7 years), and they require safety cables running through them. If an extension spring snaps, that cable catches the broken pieces and prevents them from flying across your garage.
Extension springs work fine for lighter doors. If your garage door weighs more than 300 pounds or you open and close it frequently, torsion springs handle the job better.
Walk into your garage and look directly above the closed door. If you see a horizontal spring wound tightly on a rod in the center, you have a torsion spring. If you see two springs running along the sides of the door, near the top tracks, those are extension springs. That's it. No guessing required.

A snapped spring doesn't just stop your door from working. It puts immediate stress on your opener, strains the cables, and can damage the tracks. Even a single broken extension spring makes the door unbalanced and harder to lift safely. If you're dealing with a snapped spring right now, don't force the opener. Forcing it will cause expensive secondary damage.
I've written a detailed guide covering what happens when springs fail and the real costs involved. That post walks through scenarios and ballpark numbers you can expect to budget. Understanding why springs fail helps prevent future problems, too. Temperature swings in the foothills, rust from humidity, and wear from daily use all shorten spring life.

Springs last longer when you maintain them. Regular lubrication, keeping the door balanced, and checking for rust spots catches problems before they become failures. A quick tune-up costs far less than an emergency replacement. Our garage door maintenance in Proctorville guide breaks down what actually needs doing and why.
I also recommend checking your opener type. Some belt-drive and chain-drive openers work better with specific spring types. If you're curious about which opener you have and whether it matches your springs efficiently, our belt vs. chain garage door opener comparison covers the details.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with regular use and maintenance. Extension springs usually last 5 to 7 years. Lifespan depends on how often you use the door, climate conditions, and how well you maintain it.
Can I replace a garage door spring myself? No. Springs are under extreme tension and can cause serious injury or death if they slip during removal or installation. Always hire a licensed technician with proper tools and training to handle spring replacement safely.
Why does my garage door opener run but the door doesn't move? A snapped torsion or extension spring is the most common cause. Springs do most of the lifting work, not the opener. If springs are broken, the opener can't raise the door. Stop using it immediately and call for service.
How much does spring replacement cost in Proctorville? Torsion spring replacement typically costs $200 to $400 per spring, depending on the door size and weight. Extension springs cost less, usually $150 to $250. We provide free estimates with no obligation.
Should I replace both springs if one breaks? Yes. If one spring breaks, the other is likely near the end of its life. Replacing both at the same time prevents a second failure weeks later and keeps your door balanced and functioning properly.
