A customer called last Tuesday asking why her garage door wouldn't close smoothly. She'd heard a loud noise the night before and was afraid something catastrophic had happened. After a quick conversation, I knew exactly what she needed to know: her torsion spring was likely near failure. The truth is, most homeowners in Scotland don't know whether they have torsion or extension springs, and that knowledge gap costs them time and money when something goes wrong.
Your garage door springs fall into two categories: torsion springs and extension springs. Torsion springs sit horizontally above your door, wound tightly like a clock spring. They twist and untwist to lift and lower the door. Extension springs run vertically on either side of the door opening and stretch as the door descends. See our guide: Garage Door Spring Repair Cost in Scotland.
The difference matters because they fail differently, cost different amounts to replace, and require different safety precautions. A snapped spring on a torsion system often makes a loud bang. An extension spring that breaks is usually quieter but leaves your door dangerously unbalanced.
Most homes in Scotland use torsion springs because they last longer and operate more smoothly. Garage door springs typically last 7 to 9 years depending on how often you use your door. If yours has been up for longer than that, you're living on borrowed time. See our guide: Garage Door Springs in Scotland.
Stand inside your garage with the door closed. Look directly above the door, centered on the header. If you see a thick metal rod running left to right with coils wrapped around it, that's your torsion spring. It's usually about the thickness of a marker and sits in the middle of that horizontal shaft.
If instead you see springs hanging vertically on each side of the door frame, those are extension springs. They'll look stretched when the door is down and relaxed when it's up. Extension springs are more common in older homes and smaller residential doors.
You can also check your garage door opener manual or take a photo and send it to us for a free identification. There's no shame in not knowing.
When a torsion spring fails, your door becomes extremely heavy and potentially dangerous to operate. The opener can't lift it properly. Continuing to use the door risks damaging the opener motor or injuring someone. A snapped torsion spring usually requires professional replacement because the tension is too great to handle safely.
Extension springs fail more gradually sometimes, but a completely broken one leaves the door unbalanced. You might get the door open or closed, but it won't stay put reliably. That's a safety hazard for anyone under the door.
Here's what I tell people: don't try to replace springs yourself. The tension in these springs is enormous, and a slip means serious injury. A professional can diagnose which spring failed, order the correct part, and replace it with the right tools and safety procedures.
If you're noticing your door is slow to open, hesitates mid-way, or you heard a sudden loud noise, your springs might need attention. Read our guide on what happens when garage door springs fail for more warning signs.

Once you know which type of spring you have, the next question is whether it can be repaired or needs replacement. Most of the time, a snapped spring means full replacement of that spring (or both springs if they're matched). Repair isn't really an option on a broken spring. However, if you're hearing noises but the door still operates, sometimes lubrication or minor adjustments help.
Our pricing is straightforward with no hidden fees. We'll give you an honest estimate before we start any work. If you want to understand what a typical repair or replacement costs, check our detailed breakdown on garage door spring repair costs and same-day fixes.
Don't wait for a complete failure. If your door is struggling, noisy, or unbalanced, contact a professional now. The longer you operate on a worn spring, the more damage you risk to the opener and the door itself. Plus, a worn spring can snap suddenly when you least expect it.

Springs don't last forever, but they don't have to fail catastrophically either. Knowing which type you have and catching problems early keeps your door safe and your garage running smoothly.
How long do garage door springs last? Most springs last 7 to 9 years with average use (about 10,000 cycles). Heavy use shortens that lifespan. Springs don't wear out gradually; they typically fail suddenly once they reach the end of their service life.
Can I replace a garage door spring myself? No. Springs carry extreme tension that can cause serious injury or death if mishandled. Always hire a licensed professional with proper tools and safety equipment. This is not a DIY repair.
What's the cost difference between torsion and extension spring replacement? Torsion springs are generally more expensive but last longer and operate more smoothly. Extension springs cost less upfront but need replacement more often. A professional estimate accounts for your specific door and spring type.
How do I know if my spring is about to break? Listen for creaking or popping sounds. Watch for the door moving slower than usual, hesitating mid-cycle, or sitting unevenly. A loud bang usually means it's already broken. Any of these signs warrant a same-day inspection.
Do both springs need to be replaced at the same time? If one spring breaks, it's wise to replace both. Matched springs wear evenly and ensure your door operates smoothly. Replacing only one leaves an imbalance and the other will fail soon after.
