If you've noticed your garage door moving slower than usual or heard a loud bang from the garage, your springs might be failing. A snapped spring can leave your door completely stuck, and ignoring early warning signs often leads to an emergency call when you're already running late. Understanding what to watch for helps you stay ahead of the problem.
Your garage door weighs 300 to 500 pounds. Two springs (or sometimes one, on older systems) do nearly all the heavy lifting. These springs store and release tension thousands of times over their lifespan, which is why they fail predictably around 7 to 9 years of normal use. Most homeowners don't think about springs until something breaks.
There are two main types. Torsion springs sit above the door on a metal rod and twist to lift the weight. Extension springs run along the sides and stretch to pull the door up. Both work equally hard, and both fail at roughly the same rate.
When you open your garage door manually (with the opener off), it should lift with moderate effort. If it suddenly feels like dead weight or jerks unevenly, one spring is likely worn or already broken. Don't keep trying to open it this way. You risk injury and further damage to the opener.
A healthy spring system opens your door in about 7 to 10 seconds. If it's creeping up or dropping down slowly, the springs are losing tension. A worn spring forces your opener motor to work harder, shortening its lifespan and increasing your long-term cost of repairs.
That sudden bang you hear in the garage? A snapped spring sounds like a rifle shot. If you hear it once, one spring has already failed. If your system has two springs and one breaks, the remaining spring struggles to support half the load, and it will fail within weeks. This is not something to delay.
Look at your torsion springs from a distance. The coils should be evenly spaced. If you see wider gaps or loose sections, the spring is losing its ability to hold tension and needs replacement soon.
A door that slowly creeps down when you prop it up has a spring that's nearly gone. The spring can no longer hold the door's weight reliably, and you're risking a sudden drop.
Torsion and extension springs are under extreme tension. A DIY replacement attempt has led to serious injuries, including crushed fingers, broken bones, and worse. The tools required cost hundreds of dollars and are rarely worth owning for a one-time job.
Professional technicians have the right equipment, experience handling high-tension springs safely, and insurance to cover any accidents. We've covered the why DIY replacement is dangerous and what to expect with professional costs in detail elsewhere on our site.

How long do garage door springs last? Under normal use, springs last 7 to 9 years. Frequency of use, climate, and maintenance affect lifespan. Springs in harsh climates or doors opened 10+ times daily may wear faster.
Can I open my garage door if a spring is broken? Do not open it manually or with the opener. A broken spring means the door weight isn't supported, risking serious injury or further damage to the opener mechanism.
How much does a spring replacement cost? Typical replacement ranges from $200 to $400 per spring, including labor. Total cost depends on spring type, door weight, and whether one or both springs need replacement. Call for a same-day estimate.
What's the difference between torsion and extension springs? Torsion springs twist above the door and are more durable and quiet. Extension springs stretch along the sides and are common on older doors. Both need professional replacement.
Is spring replacement covered by warranty? Most spring replacements come with a 1 to 3 year parts warranty. The craftsmanship warranty on our work is typically 5 years.
