A snapped garage door spring is one of the most common failures we see, and it stops your door cold. The good news: you don't need a new door. Springs are replaceable parts, and the cost depends on which type you have, how many need replacement, and whether you tackle it yourself or call a pro.
Your garage door weighs 300 to 500 pounds. Two springs under extreme tension counterbalance that weight, making the opener's job manageable. Without them, your opener would burn out in weeks, or the door would crash down.
There are two main types: torsion springs (mounted above the door) and extension springs (on either side). Torsion springs are more durable and safer, lasting 7 to 9 years with normal use. Extension springs wear faster, typically lasting 5 to 7 years. Both types store massive amounts of energy. A snapped spring isn't just inconvenient. It's dangerous. Never try to repair or replace springs yourself unless you have genuine experience.
A stuck garage door that won't budge is the obvious sign. You might also notice the door opening or closing unevenly, sagging to one side, or making loud banging sounds when opening. Some homeowners hear a loud crack or pop, then nothing.
If you're seeing these warning signs early, you've got options. We've covered this in detail in our garage door spring warning signs guide for Gladstone homeowners, which walks through what to listen and look for before a complete failure.
Torsion springs are pricier upfront, typically $150 to $300 per spring plus labor. Extension springs run $75 to $150 per spring. Most doors have two springs, so you're looking at $300 to $600 in parts alone.
Labor is where the real cost lands. Spring replacement requires special tools (a winding rod, safety cables, proper measuring equipment). A professional visit near me in Gladstone runs $200 to $400 in labor. Total estimate for a torsion spring replacement: $500 to $700. Extension springs: $350 to $500.
Why the jump? Torsion springs are wound under tension and require precise calibration. One mistake can mean the door doesn't open smoothly, or worse, it crashes. We don't cut corners on that work.

Sometimes one spring snaps while the other is still healthy. Do you replace just the broken one, or both? The industry standard is to replace both, even if only one failed. Here's why: if one spring has reached its end of life, the other isn't far behind. Replacing both now saves you a second service call and labor charge in a few months.
If both springs are relatively new (under 5 years old) and only one failed due to a manufacturing defect, replacing just that one is reasonable. We'll be honest about it during your estimate.

Regular maintenance extends spring life. A tuneup every year or two keeps your door balanced, reduces strain on springs, and catches wear early. Lubricating the springs quarterly with garage door grease (not WD-40) helps too.

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 usage frequency, maintenance, and climate. Springs in humid areas rust faster and fail sooner.
Can I replace one spring instead of two? Technically yes, but replacing both is smarter. If one failed, the other is under similar stress and will fail soon. You'll save money and hassle by replacing both at once and avoiding a second service call.
What does a garage door spring replacement cost in Gladstone? Expect $350 to $700 total, depending on spring type (extension or torsion), whether you replace one or both, and labor rates. We provide a detailed estimate before starting work, no hidden fees.
Is it safe to DIY a spring replacement? No. Springs carry extreme tension. A slip or miscalibration can cause serious injury or door damage. Always hire a licensed professional with proper tools and training.
Why is my garage door off balance after a spring breaks? One spring supports half the door's weight. When it snaps, all weight shifts to the remaining spring and opener, causing the door to sag or bind. This is why immediate professional help matters.
