Your garage door relies on one critical component to lift 300 to 400 pounds smoothly: the spring system. In Portland, most homes use either torsion or extension springs, and knowing which one you have saves money and headaches. We'll explain how they work, what they cost, and when to replace them.
Torsion springs sit horizontally above your garage door opening. They twist as your door opens and closes, storing mechanical energy that counterbalances the door's weight. This design is precise, efficient, and safer than the alternative.
Most Portland homes built in the last 20 years have torsion springs. They last 7 to 9 years on average with regular use. If you open and close your door 4 to 8 times daily, expect replacement within that window. The cost typically ranges from $200 to $400 for a single spring, including labor.
Why are they better? Torsion springs fail predictably. You won't wake up to a snapped spring that crashed your door. They also balance your door more evenly, reducing wear on your opener and rollers.
Extension springs run along both sides of your door, above the horizontal tracks. They stretch as your door lowers and contract as it rises. Older homes, especially in the Salem area nearby, often have these.
Extension springs are cheaper upfront (around $150 to $250 per spring), but they come with trade-offs. They wear faster because they're under constant tension. A snapped spring can send your door plummeting, which is genuinely dangerous. That's why building codes now require safety cables through the center of extension springs.
If your door has extension springs and one breaks, both usually need replacement at the same time. Uneven tension pulls your door off-track or damages your opener.

Stand inside your garage and look up at your door. If you see a single coiled spring running horizontally across the top, you have a torsion system. If you see two springs running vertically on each side, those are extension springs.
Don't touch them. Springs hold enormous tension. A snapped spring can cause serious injury. That's not fear-mongering; it's physics.
A snapped spring is obvious: your door won't open, or it opens unevenly and stops halfway. But earlier warning signs matter too. If your door feels heavier than usual or your opener struggles to lift it, springs are likely weakening.
Some homeowners hear a loud bang from the garage. That's often a torsion spring breaking under load. If this happens, stop using your door and call a professional. We offer same-day estimates and can often repair or replace springs the same day you call. Check out our garage door spring repair guide for more details on what homeowners need to know.
Here's honest pricing for Portland homeowners. A single torsion spring replacement runs $200 to $400. Extension springs cost less per spring but often need replacing in pairs, so budget $300 to $500 total. Labor is included in those figures.
If both torsion springs fail at once, expect $350 to $600 plus service call fees. We don't charge hidden fees here at Garage Door Portland. Our estimate includes everything.
Lifespan depends on your door's cycle count. One cycle equals one open and one close. A typical residential door cycles 1,500 to 2,000 times per year. Springs rated for 10,000 to 15,000 cycles last 5 to 10 years. Commercial-grade springs rated for 25,000 cycles last longer but cost more.
Springs can't be repaired; they must be replaced. Once a spring snaps or loses tension, it's done. You can't recoil a torsion spring or re-tension an extension spring safely. A new spring is your only option.
However, if your springs are aging but not yet broken, preventive replacement saves money. Replacing both torsion springs before one fails costs less than an emergency replacement and a damaged door. We can assess your springs during a maintenance visit and recommend the right timing.
Spring replacement is not a DIY project. The tension is too dangerous. A snapped spring can cause permanent injury or death. We've seen garage door injuries in Portland and surrounding areas; they're preventable with professional service.

How long do garage door springs last? Torsion springs typically last 7 to 9 years. Extension springs last 5 to 7 years. Lifespan depends on cycle count and maintenance. Springs rated for 10,000 cycles last shorter; those rated for 25,000 cycles last longer.
Can I replace one spring if only one breaks? With torsion springs, yes, though replacing both at once is smarter. With extension springs, both should be replaced together for balanced operation. Mismatched spring ages cause uneven door movement.
What does a snapped spring sound like? A loud bang or crash from your garage, usually when the door is opening or closing. The door may stop midway or hang unevenly. Stop using it immediately and call a professional.
How much does spring replacement cost in Portland? Single torsion spring: $200 to $400. Both torsion springs: $350 to $600. Extension springs: $300 to $500 total. Cost varies by spring type and labor time.
Is spring replacement an emergency? If your door is stuck or unsafe, yes. A snapped spring creates a safety hazard. We offer same-day service across Portland and can often fix it the day you call.
