When your garage door won't open or you see a snapped spring hanging loose, the first thing you need to know is which type of spring failed. Torsion springs and extension springs do the same job but work completely differently. Understanding this distinction helps you communicate with a technician, understand your repair cost, and avoid dangerous DIY attempts. Here's what every Winlock homeowner should know.
Most modern homes in Winlock and nearby Longview use torsion springs. These sit horizontally above your garage door opening, on a metal rod. When the door closes, the springs twist and wind up, storing energy. When you open the door, that twisted energy releases and lifts the weight. A typical residential torsion spring lasts 7 to 9 years with normal use.
Torsion springs handle the load more efficiently than extension springs. They're also safer because the spring is contained above the door, away from people and vehicles. If one snaps, it stays in place rather than whipping across the garage.
The trade-off: torsion springs cost more to replace than extension springs. But that higher upfront cost reflects their durability and safety advantage. A torsion spring replacement usually runs between $250 and $400 for parts and labor at Garage Door Winlock, depending on your door's weight and spring quality.
Extension springs run along the left and right sides of your garage door opening. They stretch and contract like a rubber band, extending as the door closes and contracting as it opens. You'll find these springs on older homes and lighter residential doors.
Extension springs are cheaper to buy and install initially. However, they don't last quite as long and pose a safety risk if one snaps. A broken extension spring can whip violently and cause injury or property damage. That's why many homeowners upgrade to torsion springs when their extension springs fail.

Step outside and look above your garage door opening. If you see a long horizontal rod with springs wound around it, you have torsion springs. If you see springs running vertically along both sides of the opening, those are extension springs. Most doors use one spring or two springs depending on door size and weight.
Don't try to repair or adjust springs yourself. Even though torsion springs are safer than extension springs, both store tremendous energy. A spring under tension can cause serious cuts, broken bones, or eye injuries. That's why professional technicians use special tools and follow strict safety protocols.
The type of spring you have influences repair cost, replacement time, and future maintenance. Torsion springs need precise balancing, specialized equipment, and expert knowledge. Extension springs are simpler to install but require cable safety hardware to prevent injury if the spring snaps.
Learn what to expect when budgeting for spring repairs, including labor, parts, and whether a full replacement makes sense versus a repair. If you have a snapped spring that's preventing your door from opening, schedule a free quote and we'll give you an honest estimate today.
If you're replacing extension springs, this is an ideal time to upgrade to torsion springs. The installation cost difference isn't huge, and you'll gain better safety, longer lifespan, and smoother operation. Many Winlock homeowners make this switch and never regret it.
If you already have torsion springs, stick with that system. Your door opener, door weight, and hardware are all configured for torsion operation. Changing to extension springs would require rebuilding other components.
The best choice depends on your current setup, door weight, and budget. Call us at (360) 637-1102 for a same-day estimate, or book your spring inspection online and we'll recommend the right option for your home.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs may last 5 to 7 years. Lifespan depends on door cycles, climate, and maintenance. Winlock's moisture can accelerate wear if springs aren't lubricated regularly.
Can I replace just one spring if the other is fine? Both springs age together and experience the same cycles. Replacing only one creates imbalance and puts extra stress on the remaining spring, causing early failure. We always recommend replacing both springs at the same time.
Why is torsion spring repair more expensive than extension? Torsion springs require special tools, precise balancing, and advanced technical knowledge. The spring rod must be wound to exact tension based on your door weight. Extension springs are simpler but less safe and don't last as long.
What happens if a spring snaps while the door is open? If a torsion spring snaps while the door is fully open, it usually stays contained on the rod above the opening. The door won't fall because the opener is holding it up. You'll need a technician to replace the spring before you can use the door again.
Does weather in Winlock affect spring lifespan? Yes. Our wet climate encourages rust and corrosion on unprotected springs. Annual lubrication and inspection prevent rust and extend spring life. Moisture accelerates wear on the cable and hardware too.
