In our years serving Plano, we've seen this problem again and again: homeowners don't know which type of garage door spring they have until one snaps. The spring type determines repair cost, replacement timeline, and whether a DIY fix is safe (it isn't). Torsion and extension springs work differently, fail differently, and cost different amounts to replace. Knowing which one you have means smarter decisions and honest pricing.
Most modern homes in Plano use torsion springs. These coiled springs sit horizontally above your garage door and twist (torsion) to counterbalance the weight. When you open the door, the spring unwinds. When you close it, the spring winds back up.
Torsion springs handle the load more efficiently than extension springs. They're mounted on a steel rod and controlled by cables, making them safer and more reliable. A properly installed torsion spring lasts 7 to 9 years with normal use, depending on how often you cycle the door open and close.
The downside? Torsion springs are under tremendous tension. A snapped spring means the door becomes deadweight instantly. You cannot open it manually without serious injury risk. That's why professional replacement isn't optional here.
Torsion spring replacement typically runs higher than extension springs because the coil design requires precision winding and the installation involves working under extreme tension. A single torsion spring can cost between $150 and $300 depending on wire gauge and spring length. Labor adds another $200 to $400. We always give an honest estimate before we touch anything.
Older Plano homes sometimes still have extension springs. These hang on either side of the door and stretch (extend) to lift the weight. When the door goes up, the springs extend. When it closes, they contract back.
Extension springs are simpler mechanically, which is why they used to be standard. They're also cheaper to manufacture. However, they're less efficient at load distribution and typically wear out faster than torsion springs, often lasting only 5 to 7 years.
If one extension spring snaps, the other shoulder most of the load, causing premature failure on the second side. You'll usually need to replace both springs at the same time to avoid an unbalanced door.
Extension springs come with safety cables running through the center. If the spring snaps, the cable catches it and keeps the spring from launching across your garage like a deadly projectile. This is real protection, but it's not a substitute for professional replacement.

Look at your garage door from inside the garage. Is the spring coiled horizontally above the door? That's torsion. Are there two springs hanging vertically on either side of the door opening? Those are extension springs. When in doubt, take a photo and text it to us, or we can diagnose it during a free in-person estimate.
If you see a snapped spring dangling or hear a loud BANG when you tried to open the door, don't attempt a DIY fix. This isn't a skill saw or a leaky faucet. One mistake and you're looking at a crushed hand or worse.
We price torsion spring replacement honestly because we believe homeowners deserve transparency. A snapped torsion spring in Plano runs $400 to $600 installed, depending on spring quality and your door weight. Extension springs are typically $300 to $450 per pair.
Emergency service costs more, especially after hours. Same-day appointments cost a small premium, but if your garage door is stuck and you need to get your car out or secure your home, it's money well spent. We've got the parts and expertise to handle it without delay.

Both spring types require specialized equipment and safety knowledge. We use proper winding cones, tension bars, and safety cables every time. One slip with tension this high can cause serious injury. This is why we recommend calling a professional for spring replacement when a professional is necessary.

How long do garage door springs actually last? Torsion springs last 7 to 9 years with typical use (about 3 to 5 cycles daily). Extension springs last 5 to 7 years. Lifespan depends on usage frequency, door weight, and maintenance habits.
Can I replace a garage door spring myself? No. Spring replacement requires specialized equipment and carries extreme risk of serious injury or death. Tension stored in springs can launch coils at high speed. Always hire a licensed professional.
What's the difference in cost between torsion and extension springs? Torsion springs typically cost $400 to $600 installed. Extension springs (usually replaced in pairs) run $300 to $450 per pair. Torsion is pricier but lasts longer and performs better.
Why do springs snap without warning? Springs wear from constant cycling. Rust accelerates wear in humid climates like North Texas. One day the spring reaches its breaking point and snaps suddenly. Regular maintenance inspection helps catch weak springs early.
Is emergency spring replacement more expensive? Yes. After-hours or same-day service includes a small premium for dispatch and availability. We're honest about costs upfront and available when you need us most.
