Here's what most homeowners don't realize about garage door springs: they're under roughly 200 pounds of tension, they wear out predictably (7 to 9 years, not 10), and a snapped spring can send your door crashing down with enough force to crush a car or injure someone standing nearby. I've seen the aftermath. It's not pretty, and it's 100 percent preventable with basic awareness and professional help.
Garage door springs are the unsung workhorses of your home. Without them, your garage door opener would need to lift the full weight of the door itself, which typically ranges from 300 to 600 pounds. Springs counterbalance that load, making it easy for your opener to do its job. But springs aren't forever. They fail. And when they do, you'll know immediately because your door won't open, or it'll open partially and slam shut.
Your garage door uses one of two spring systems: torsion or extension springs. Understanding which one you have matters because they fail differently and require different replacement approaches.
Torsion springs sit horizontally above your garage door, running parallel to the header. They twist and unwind thousands of times over their lifespan. When a torsion spring snaps, the door typically won't budge, and you'll hear a loud bang that sounds like a gunshot. This is the most common spring type in modern homes.
Extension springs run vertically along the sides of your door tracks. They stretch and contract to support the door's weight. If an extension spring fails, the door often hangs unevenly or drops suddenly on one side. Both types are equally dangerous to replace yourself, and I strongly advise against it.
Let me be direct: replacing garage door springs yourself is one of the most dangerous home repair projects you can attempt. Every year, emergency rooms treat hundreds of people for garage door-related injuries, many involving springs. Here's why professionals exist.
Springs stay compressed even when your door is open. Releasing that tension without proper tools and training can cause serious lacerations, broken bones, or eye injuries. A slip of the wrench, a miscalculation of spring tension, or a moment of distraction can result in permanent disability. I've seen homeowners attempt this and end up in the ER.
Beyond safety, improper installation ruins the balance of your door. An unbalanced door wears out your opener faster, strains your tracks, and creates more danger the next time something goes wrong. It's a domino effect of expensive problems.
Knowing the warning signs helps you get ahead of a complete failure. Listen for unusual noises: creaking, grinding, or high-pitched sounds from above the door suggest friction and wear. Watch for an uneven door. If one side hangs lower than the other, a spring is weakening.
If your garage door opens slowly, struggles to lift, or feels heavy, the springs are losing their strength. Some doors open partway then reverse. That's a sign one spring has already failed and the other is compensating. Don't ignore these signals. A complete failure can happen within days.

Spring replacement cost varies based on whether you need one or both springs replaced, your spring type, and door size. Our pricing guide covers the main factors affecting your quote, but springs typically run between $200 and $600 per spring, including labor.
A single snapped spring might cost less initially, but I usually recommend replacing both at the same time. Why? They wear together. If one has failed, the other is likely nearing the end of its life. Replacing both prevents a second service call in three months.
Same-day service is possible for spring replacement in most cases. We carry common torsion and extension spring sizes and can typically complete the job within a few hours. Schedule your free estimate today and we'll assess which approach makes sense for your door.
You can't prevent springs from eventually wearing out, but you can extend their lifespan significantly. Regular lubrication of springs, tracks, and hinges reduces friction and stress. An annual maintenance tune-up catches wear early and keeps your door operating smoothly. Our maintenance guide walks you through what homeowners should check between professional visits.
Keep your garage door balanced. A properly balanced door puts less strain on springs. If your door feels heavy or uneven, springs may already be compensating. Don't wait.

How long do garage door springs last? Most garage door springs are rated for 7 to 9 years of normal use, or roughly 10,000 to 15,000 cycles. Frequency of use, climate, and maintenance affect lifespan. Springs in humid areas like the Pacific Northwest may wear faster due to rust and corrosion.
Can I open my garage door if a spring is broken? Do not attempt to open a door with a broken spring using the opener. You risk injury and damage to the opener. Use the emergency release and lift the door manually only if it's safe. Call a professional immediately for replacement.
Why is spring replacement so expensive? Spring replacement requires specialized knowledge, equipment, and liability insurance. The danger and precision involved justify the cost. Attempting it yourself risks injury far more costly than professional service.
What's the difference between a snapped and a weakened spring? A snapped spring breaks completely, causing sudden door failure. A weakened spring still functions but struggles to balance the door's weight, leading to slow operation and uneven movement. Both require professional replacement.
