A snapped spring is the most common reason a garage door stops working. Torsion springs sit above your door and twist to lift the weight; extension springs run along the sides and stretch. Both fail around 7 to 9 years with normal use. Knowing which type you have and what to expect when it breaks saves you time, stress, and money.
Your garage door weighs 300 to 400 pounds. Without springs, your opener motor would burn out in weeks trying to lift that load alone. Springs counterbalance the door's weight, making it feel light when you open or close it.
Two main types handle this job: torsion springs and extension springs. Torsion springs coil around a metal rod mounted horizontally above the door opening. As the door moves down, the springs wind tighter, storing energy. When you open the door, that stored energy unwinds and helps lift the weight.
Extension springs work differently. Mounted on each side of the door track, they stretch as the door closes. Metal cables attached to the bottom of the door pull the springs open when you lift the door. This stretching action stores and releases energy.
Both designs are engineered to handle thousands of cycles. A typical residential door opens and closes 3 to 5 times per day. Over 7 to 9 years, that adds up to thousands of lifts and lowering cycles before metal fatigue takes over.
A broken spring doesn't always announce itself with a loud bang, though many do. Here are the real warning signs you'll notice.
The door feels heavy. If your opener struggles or the door moves unevenly, a spring may be weakening. You might hear the motor working harder than usual.
The door won't stay up. If you open it manually and it slides back down slowly, one or both springs have lost tension.
Visible wear on the springs themselves. Look at the rod above your door (torsion) or along the side tracks (extension). Rust, gaps in the coils, or obvious separation means replacement is coming soon.
The door tilts to one side. When one spring fails before the other, the door hangs crooked as it opens or closes.
Don't ignore these signs. A failing spring puts extra stress on your opener motor and can damage the door itself. More importantly, a completely snapped spring can cause the door to drop suddenly, creating a safety hazard.

Torsion springs are the professional choice. They last longer, work more smoothly, and are safer because the springs stay contained above the door. If one snaps, the cables and brackets usually keep it from flying across your garage.
Extension springs are cheaper upfront but require safety cables running through them. If an extension spring breaks and the cable fails, the spring can snap violently across the garage. That's why safety cables exist, but the risk is higher.
Most homes built in the last 20 years use torsion springs. Older homes and some budget installations lean toward extension springs. If you're unsure which yours are, open your garage and look above the door. Torsion springs sit on a horizontal rod and look like tight coils. Extension springs run along the vertical tracks on either side.
Spring replacement cost depends on the type, how many springs need work, and whether you replace them yourself or hire a professional.
DIY replacement isn't recommended. Springs are under extreme tension. A mistake can cause serious injury or property damage. Professionals have the right tools, experience, and knowledge to do it safely. For a detailed breakdown of what you might expect to pay, read our guide to garage door springs cost and replacement timelines.
Most homeowners should plan for professional installation. A technician can also spot other issues while the door is apart, like worn cables, damaged tracks, or opener problems. This prevents surprise repairs later.
You can't stop springs from aging, but you can slow the process. Regular lubrication of the springs, cables, and tracks reduces friction and extends their life by a year or two.
Also check your opener balance monthly. Open the door manually (no opener) and release it halfway up. It should stay put. If it drifts down, springs are weakening and replacement is near.
For a complete maintenance routine, check our guide to stopping breakdowns before they start. Routine care catches small problems early and keeps your door operating smoothly.

How long do garage door springs last? Most springs last 7 to 9 years with normal residential use (3 to 5 cycles per day). Heavier use or extreme weather can shorten that window. Manufacturer ratings are often higher, but real-world lifespans tend to fall in this range.
Can I replace just one spring? Technically yes, but both springs wear at similar rates. If one breaks, the other is likely close behind. Replacing both at once prevents a second failure weeks later and ensures balanced door movement.
Why did my spring break without warning? Springs fail due to metal fatigue over time. Rust, moisture, and constant expansion/contraction weaken the metal. A sudden snap often happens when you least expect it, even if you saw no obvious signs beforehand.
Are extension springs more dangerous than torsion springs? Extension springs carry higher risk if the safety cable fails. Torsion springs are contained above the door, so a break is usually safer. That's why safety cables are essential on extension spring systems and why many homeowners prefer torsion setups.
Should I repair or replace my entire garage door? Spring replacement alone is almost always the right call. Only consider full door replacement if the door panels are damaged, rusted, or cosmetically worn. Springs are consumable parts, like brake pads on a car. Replacing them doesn't mean the door is done.
