Signs Your Garage Door Spring Is Broken
Don't try to open the door manually if you suspect a broken spring — the tension involved makes it dangerous to handle without the right tools.
Visible Gap in the Spring
The most obvious sign — a clear break or gap in the coil above the door.
Door Feels Extremely Heavy
Springs carry most of the door's weight — without one working, lifting it manually feels dramatically harder.
Door Won't Stay Open
Without spring tension holding it up, the door may drift or fall shut on its own.
Loud Bang From the Garage
A sudden, loud bang is often the sound of the spring itself breaking under tension.
Door Opens Unevenly
If one side lifts faster than the other, one spring (on dual-spring systems) may have failed.
Opener Struggles or Stalls
Without spring assistance, the opener motor works much harder and may stall partway.
What Happens When a Garage Door Spring Breaks?
Garage door springs counterbalance most of the door's weight, so the opener only has to manage a small fraction of it during normal operation. When a spring breaks, that balance is gone — the opener suddenly has to lift far more weight than it's designed for, which can strain the motor, gears, and cables well beyond a single incident. Continuing to operate the door with a broken spring risks damaging other components and is genuinely unsafe, given the tension involved. If you're seeing other symptoms alongside a suspected spring issue, our general garage door repair page covers the broader range of what we diagnose and fix.
Garage Door Spring Repair Process
Contact Heritage
Call or request service online and describe what you're seeing — a gap in the coil, a heavy door, or a bang you heard.
We Inspect the Spring System
We identify the spring type, check related hardware like cables and pulleys, and explain what needs to be replaced.
Replace and Test
We install the correct replacement spring, rebalance the door, and test its operation before we leave.
Torsion vs. Extension Springs
Torsion Springs
Mounted on a shaft above the door, torsion springs are the more common setup on newer garages and generally offer smoother operation and a longer service life.
Extension Springs
Installed along the horizontal tracks on each side of the door, extension springs are common on older or lighter garage door systems.
We service both types. Actual lifespan in years varies depending on how frequently the door is used and which spring system is installed — for a look at what affects repair and replacement cost, see our garage door spring cost guide.
