Most homeowners in Sherwood don't know they have two completely different spring systems until one snaps. The type of garage door spring you own determines how your door operates, how long it lasts, and what happens when it fails. Let's cut through the confusion about garage door springs and help you understand which one you have and why it matters for your safety and wallet.
Torsion springs wind around a metal rod above your garage door opening. They store energy by twisting (torque), then release that energy to lift your door smoothly. These springs are mounted horizontally on a shaft, usually centered above the doorway.
Here's the critical safety detail: torsion springs are under extreme tension. A snapped torsion spring doesn't just stop working. The sudden release can cause the door to crash down with thousands of pounds of force. I've seen vehicles damaged and, worse, injuries that could have been prevented if the homeowner had recognized the warning signs earlier.
Torsion springs typically last 7 to 9 years with normal use. If your door opens and closes 10 to 15 times daily, you're looking at the lower end of that range. One spring system usually means your entire door weight is balanced on a single spring. If it breaks, your door won't open at all.
Extension springs run horizontally along both sides of your garage door opening, below the horizontal tracks. Instead of twisting, they stretch and contract to support the door's weight.
Extension springs are less powerful individually, which is why garage doors typically have two of them working together. This design has a safety advantage: if one extension spring snaps, the other can still hold the door partially supported. You won't have a catastrophic crash, though you should stop using the door immediately.
These springs also live longer than torsion springs in many cases, sometimes reaching 10 to 12 years. However, they require more frequent lubrication and inspection because they're more exposed to dust and moisture here in Sherwood and surrounding areas like Tigard and Wilsonville.
Springs don't just break randomly. Metal fatigue from constant expansion and contraction causes micro cracks that eventually lead to failure. A snapped spring usually happens without warning, but you can catch problems before that happens.
If your door feels heavier than usual, opens or closes slowly on one side, or makes a loud bang sound, those are your warning signals. A torsion spring failure often produces a distinctive CRACK sound. An extension spring typically snaps with a loud PING. Both are emergencies.

This depends on age, damage, and cost. If your springs are under 5 years old and only one is damaged, repair might make sense. If both springs are approaching 9 years, replacing both at once is smarter and safer. A single spring replacement costs less upfront, but replacing the second spring months later doubles your labor costs.
We've detailed the repair versus replace decision in depth on garage door springs in Sherwood, repair vs. replace on a budget, which walks through the financial trade-offs.
Not all garage door companies handle spring work the same way. Springs require specialized tools, knowledge, and safety equipment. A DIY attempt can result in serious injury. The tension in these springs is powerful enough to cause broken bones or worse.
When you call for an estimate, ask if the company offers same-day service and whether they carry replacement springs on their trucks. Garage Door Sherwood stocks both torsion and extension springs for immediate replacement, so you're not waiting days for parts. Many competitors order springs after they diagnose the problem, leaving you without a working garage door while you wait.

Spring replacement cost varies based on spring type, door weight, and whether you're replacing one or both. Torsion springs cost more than extension springs because they're more specialized. A single torsion spring replacement typically runs $200 to $400 including labor. Extension springs run $150 to $300. If both springs need replacement, expect to add another $150 to $250 to the total.
These prices assume professional installation. That's non-negotiable for safety reasons. To discuss your specific situation and get an accurate estimate, schedule a free quote with our team.
A broken or failing spring is a same-day repair situation. Your garage door represents a significant security point in your home. A non-functioning door leaves your garage vulnerable. It also creates a safety hazard if the door is stuck partially open or if someone tries to operate it manually without understanding the danger.
If you're hearing strange noises, noticing the door moves unevenly, or suspect a spring has failed, don't test it. Call us right away at 541-933-4777.

How long do garage door springs last? Torsion springs typically last 7 to 9 years; extension springs last 10 to 12 years. Lifespan depends on usage frequency, climate, and maintenance. Proper lubrication extends spring life.
Can I replace a garage door spring myself? No. Spring replacement requires specialized tools and knowledge. The tension stored in springs is extremely dangerous. Professional installation protects you and ensures proper door balance.
What's the difference between a snapped spring and a worn spring? A snapped spring breaks suddenly and completely. A worn spring weakens gradually, causing the door to open slowly or unevenly. Both require professional service, but worn springs give you time to schedule an appointment.
How much does it cost to replace garage door springs? Single torsion spring replacement: $200 to $400. Single extension spring: $150 to $300. Replacing both springs costs $350 to $650 total, which is often smarter than replacing one now and another later.
Why is my garage door suddenly heavy to open? A failing or snapped spring can't support the door's weight properly. The opener must work harder, or the door becomes impossible to open manually. This signals immediate professional attention is needed.
