Here's what most homeowners in Greenville don't realize about garage door springs: they're under extreme tension and can snap without any warning, sometimes leaving your door stuck shut or dangerously unstable. A snapped spring isn't just an inconvenience. It's a safety issue that demands immediate attention from someone who knows what they're doing.
Springs are the hardest-working component in your entire garage door system. They counterbalance the weight of your door, usually between 300 and 500 pounds, so your opener doesn't burn out after a few months. When a spring fails, that weight transfers directly to the motor, the cables, and potentially to you or your family if something goes wrong. See our guide on choosing the right garage door opener in greenville: belt drive, chain drive, and smart options explained.
Your garage door uses one of two spring types, and knowing which one you have matters for repair cost and safety.
Torsion springs sit horizontally above your garage door opening. They twist as your door opens and closes, storing and releasing energy with each cycle. Most homes built in the last 20 years use torsion springs because they're more durable and predictable. A torsion spring typically lasts 7 to 9 years under normal use.
Extension springs run vertically along each side of your door opening. They stretch and contract as the door moves up and down. Extension springs generally wear out faster than torsion springs, sometimes within 5 to 7 years, and they're more prone to sudden failure. They also require safety cables to prevent injury if a spring snaps.
If you're not sure which type you have, take a photo and send it to us. We can identify your setup and give you an honest estimate over the phone.
This is where I'm going to be straight with you. Spring replacement in Greenville typically runs between $250 and $500 per spring, depending on the type and quality. A single torsion spring replacement lands closer to $350 to $450. Extension springs cost less per spring, usually $150 to $300, but many doors have two of them.
Why the range? Quality matters. A cheap spring might last 5 years. A quality replacement lasts 10 to 12 years. I always recommend the better spring because the labor cost is the same either way. You're paying us to do the job right; you might as well install a spring that won't need replacing again in three years.
Many homeowners ask if they can replace just one spring when both are worn. My honest answer: if one spring has failed or is nearing the end of its life, the other one isn't far behind. Replacing both at once saves you a second service call and another labor charge down the road. It's cheaper overall.
We offer free estimates over the phone so you know the exact cost before we show up. No surprises, no hidden fees.

Watch for these warning signs before a complete failure leaves you stranded.
Your door moves slowly or unevenly even though your opener sounds normal. One spring is weaker than the other, throwing the door off balance. Your door falls shut faster than it should, or it won't stay open when you partially raise it. A loud bang or crack coming from above the door often means a spring just snapped. Don't ignore that sound.
If you notice any of these issues, call us for a same-day estimate rather than waiting for total failure. A proactive repair is always cheaper and safer than an emergency replacement.
I see videos online showing homeowners replacing their own springs. Don't do it. Torsion springs operate under 200 to 300 pounds of tension. If a tool slips, if you lose your grip, or if the spring unwinds unexpectedly, you can suffer serious injury. Hospital visits and permanent damage happen. The $350 you save isn't worth a broken bone.

Springs are just one part of a complete system. Your opener, cables, and hardware all work together. If you're replacing springs and your door is already 15 plus years old, it's worth discussing a full replacement to avoid cascading repairs over the next few years.

How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs wear out faster, usually within 5 to 7 years. Lifespan depends on how often you open and close your door and the quality of the spring installed.
Can I replace just one spring if the other is still working? Technically yes, but both springs are usually near the end of their life if one has failed. Replacing both now prevents a second service call and labor charge within a year or two.
What should I do if my garage door spring snaps? Stop using your door immediately. Do not force it open or closed. Call a professional spring specialist. A snapped spring can damage your opener and create safety hazards for anyone nearby.
