Your garage door has one of two spring types, and they work in completely different ways. Torsion springs twist to lift the door. Extension springs stretch and contract along the sides. Which one you have matters for cost, safety, and how fast you can get same-day service. Let's cut through the confusion so you understand what's holding up that 400-pound door.
A torsion spring is mounted horizontally above your garage door opening. It twists (or torques) as your door opens and closes. The spring stores energy as it winds up, then releases that energy to help lift the door smoothly. Most modern residential doors in Gresham use torsion springs because they're safer, quieter, and more reliable than older extension designs.
Torsion springs are rated by cycles. One cycle equals one open and one close. A typical residential spring lasts 7 to 9 years with normal use (roughly 10,000 cycles). If your door gets heavy use, that lifespan shrinks. A snapped torsion spring usually means the entire spring needs replacement, not repair.
The upside: torsion springs provide balanced, smooth door operation. The downside: they're more expensive to replace than extension springs. When one fails, you'll notice immediately. The door becomes nearly impossible to open by hand.
Extension springs run along both sides of your door, parallel to the horizontal tracks. They stretch as the door closes and contract as it opens, storing and releasing energy to assist the lift. Older homes and some budget installations still use extension springs.
Extension springs come with safety cables running through the center of each spring. These cables catch a broken spring before it whips across your garage, which is a real safety hazard. Without the cable, a snapped extension spring can cause serious injury.
Extension springs are cheaper upfront than torsion springs, but they don't last as long under heavy use. They also create more noise and wear on your tracks because they don't lift the door as evenly.

A broken spring means your door won't open, or it will open unevenly and get stuck. The motor in your opener will struggle or refuse to engage. This is not a DIY fix. Spring replacement requires special tools, knowledge of tension settings, and safety precautions. Improper installation can damage your opener, tracks, or worse, cause injury.
Learn why springs snap and what triggers failure so you can spot warning signs before disaster strikes.
Torsion spring replacement typically costs more than extension spring replacement because the parts themselves are pricier and installation requires more precision. However, torsion springs last longer and perform better, so the long-term value is often better. Extension springs may save you money initially, but you might replace them more frequently.
Your actual cost depends on spring size, door weight, and whether you need one spring or both replaced. Get a free estimate on garage door repair costs in Gresham to understand what you're looking at.
Open your garage and look above the door. If you see a horizontal coiled spring stretching across the top, that's torsion. If you see springs running vertically along the left and right sides of the opening, those are extension springs. Don't touch either one. Just identify which type, then call a professional.
Once you know what you're dealing with, you can make an informed decision about repair costs and timing. If your spring is older than 7 years and showing signs of wear, replacement might be coming soon anyway.

Regular maintenance catches small problems before they become expensive ones. Annual inspections can spot rust, corrosion, or loss of tension. Lubrication reduces friction and extends spring life. Keep your door balanced and aligned so springs wear evenly.
Don't wait for a snapped spring to ruin your day. If you're in Gresham or nearby areas and your door is old, get a professional inspection. Schedule your maintenance check today and avoid the emergency service call.
Can I replace just one spring if the other is still good? Springs wear together. If one snaps, the other is usually close behind. Most professionals recommend replacing both springs at the same time to prevent imbalance and uneven wear on your opener and tracks.
How do I know if my spring is about to break? Listen for creaking or squeaking above the door. Watch for the door opening unevenly or getting stuck partway. If your opener is straining harder than usual, that's a sign springs are losing tension and need inspection.
Is it safe to operate my garage door with a broken spring? No. A broken spring means your opener's motor is bearing the full weight of the door without spring assistance. This strains the opener and can cause damage. Stop using the door and call for service.
How long does spring replacement take? Most spring replacements take 1 to 2 hours. Same-day service is often available in Gresham depending on the time of day and your spring type.
What's the difference between a spring tune-up and replacement? A tune-up includes inspection, lubrication, tension adjustment, and minor repairs. Replacement means removing old springs and installing new ones. If springs are damaged or very old, replacement is the only option.
