Your garage door is the largest moving object in your home, and the springs do most of the heavy lifting. A typical two-car garage door can weigh anywhere from 150 to 400 pounds, and the springs counterbalance that weight so your opener (or your arms) can lift it easily. When a spring starts to fail, the whole system suffers.
The good news is that springs rarely fail without warning. Here are the signs to watch for.
1. The Door Feels Unusually Heavy
If you lift the door manually and it feels much heavier than it used to, the springs are losing tension. A properly balanced door should feel light and stay in place when held halfway open.
2. The Door Won’t Stay Open
Pull the emergency release, lift the door to about waist height, and let go. If it slams down or shoots back up, the spring balance is off and needs adjustment.
3. You See a Gap in the Torsion Spring
Torsion springs sit on a metal bar above the door. If you notice a two-inch gap in the coils, the spring has already snapped. Do not try to operate the door.
4. A Loud Bang From the Garage
Many homeowners report hearing what sounds like a gunshot from the garage. That noise is often a spring breaking under tension.
5. The Door Opens Crooked or Jerky
When one spring is weaker than the other, the door lifts unevenly. This puts stress on cables, rollers and tracks, which can lead to more expensive repairs.
6. Visible Rust or Wear
New England winters are hard on metal parts. Rust adds friction and shortens a spring’s life, so inspect your springs every few months.
7. The Opener Strains or Stops
If your opener hums, struggles or reverses halfway, it may be trying to lift a door the springs can no longer support.
Why You Should Never Replace Springs Yourself
Garage door springs store a huge amount of tension. Without proper tools and training, a winding bar can slip and cause serious injury. Spring replacement is a job for licensed professionals.
How Long Do Garage Door Springs Last?
Most standard springs are rated for roughly 10,000 cycles, which works out to about 7 to 10 years for an average household. High-cycle springs last much longer and are worth considering if your family uses the garage as its main entrance.
