If your garage door suddenly won't open, a snapped spring is usually the culprit. Garage door springs in Coos Bay typically cost between $150 and $400 per spring for parts and labor combined, depending on whether you need torsion or extension springs replaced. The real variable isn't the spring itself. It's your door's weight, the spring type, and whether you're replacing one or both.
Garage door springs work under tremendous tension. A standard residential door weighs 300 to 400 pounds. Those springs support that entire load every single time the door moves. Springs last about 7 to 9 years under normal use, which translates to roughly 10,000 to 15,000 open-close cycles.
Here's what most homeowners don't realize: springs don't gradually wear out. They snap. One day your door works fine. The next day you hear a loud bang from the garage, and suddenly your door is dead weight. The coastal humidity and salt air along the Oregon coast actually accelerates corrosion, so Coos Bay homeowners often see spring failure on the earlier end of that timeline.
Two main types exist: torsion springs (mounted horizontally above the door) and extension springs (mounted on each side). Torsion springs are more common, more durable, and more expensive to replace. Extension springs are cheaper upfront but tend to wear faster.
A single torsion spring replacement typically runs $200 to $350 in labor plus $50 to $100 for the part itself. Extension springs are cheaper: usually $100 to $150 total per spring. But here's the catch. If one spring has snapped, the other one is right behind it. Both springs experience the same stress and age at the same rate. Replacing only one now means you'll be calling us back in a few months when the second one fails.
Most professionals recommend replacing both springs at once, even if only one has snapped. That's a smarter move financially and keeps your door running smoothly. Two springs will cost you $300 to $600 total, but you avoid a second service call and emergency fee.

Labor makes up the bulk of your cost. Spring replacement requires specialized tools (a winding bar), safety equipment, and knowledge of proper tensioning. This isn't a job for YouTube videos and borrowed equipment. A snapped spring under tension can cause serious injury. I've seen homeowners lose fingers trying to DIY this work.
Door weight is the primary driver. A single-car door costs less to spring than a double-car or oversized door. Custom or insulated doors (common in coastal areas because of our weather) weigh more and need heavier springs, which cost more to replace.
If you need an accurate garage door quote in Coos Bay, get a technician on site. A photo won't tell the whole story. We'll assess your door's age, condition, and whether both springs need attention.
Emergency timing also matters. If your spring fails on a Saturday night or holiday, you'll pay an emergency service fee. Standard business hours calls are cheaper. That said, a broken spring leaves your garage door stuck open or closed, making it a genuine security and safety issue.
The internet is full of DIY spring replacement videos. I'm going to be direct: don't do it. A properly tensioned spring requires precise measurements and calibration. Under-tension it, and your door won't open. Over-tension it, and you risk snapping the new spring or damaging your opener.
Springs are under about 200 pounds of force per inch. If something slips during installation, that energy releases instantly. I've worked with homeowners who tried this themselves and ended up paying more for repair calls when the door stopped working mid-repair.
Our garage door spring services include full inspection, both springs (if needed), proper tensioning, and a warranty. That's worth the cost.

How do I know if my garage door spring is broken? Your door will be stuck open or closed, or it'll feel unusually heavy when you try to open it manually. You might hear a loud bang coming from the garage. Never force a door with a snapped spring.
Can I open my garage door if the spring is broken? Not safely. A broken spring means your opener bears the full weight of the door. This can burn out the motor or cause the door to fall suddenly. Wait for professional service.
How long does spring replacement take? Most jobs take 1 to 2 hours from arrival to completion. This includes inspection, removal, installation, tensioning, and testing.
Should I replace both springs even if only one broke? Yes. The second spring is experiencing the same stress and wear. Replacing both at once saves you a second service call and emergency fee within months.
What's the difference between torsion and extension springs? Torsion springs mount horizontally above the door and last longer but cost more. Extension springs mount on the sides, are cheaper, but wear out faster. Most modern doors use torsion springs.
