The Hidden Dangers of Garage Door Spring Replacement
Your garage door is probably the largest moving part in your home—and one of the most under-appreciated. But behind its smooth movement are powerful components working under extreme tension, especially the springs. When these springs wear out or snap, professional garage door repair is usually the safest way to get the door operating properly again. Many homeowners consider fixing the issue themselves. Avoid this dangerous and costly mistake.
Garage Door Springs: Small Parts, Big Risk
Garage doors typically use torsion springs or extension springs to counterbalance the heavy weight of the door. These springs are tightly wound and store massive amounts of energy. If released improperly, they can cause severe injuries or even death.
The dangers of garage door spring repair aren’t theoretical. A published medical study documented seven patients who suffered severe eye injuries after garage door springs dislodged while they were attempting repairs. The injuries included retinal detachments, permanent vision loss, and, in one case, eventual removal of the injured eye. Researchers concluded that serious eye injury is a risk when inexperienced homeowners attempt to repair garage door spring systems. Read the published study through the National Institutes of Health.
Beyond eye injuries, garage door repair accidents can also result in injuries such as cuts, broken fingers or hands, and injuries caused by falling or rapidly moving door components.
Garage door safety has long been a concern of the U.S. Consumer Product Safety Commission, which has implemented safety standards intended to reduce serious injuries and deaths associated with garage doors and garage door openers.
Why Spring Replacement Is So Dangerous
Here’s what makes spring replacement particularly risky:
- High Tension: Torsion springs store a tremendous amount of energy. If they’re not properly controlled during removal or installation, components can release suddenly and cause serious injury.
- Specialized Tools Required: Professional-grade winding bars and torque tools are essential—not household items like screwdrivers or pliers.
- Precision Matters: An incorrectly installed spring can cause your door to become unbalanced or fall, which increases wear on the opener and poses further danger. Learn more about other common problems in our Garage Door Repairs 101 guide.
- Hidden Wear: Springs may appear fine until they suddenly break. DIYers often overlook signs of internal fatigue that professionals are trained to detect.
Stay Safe: Know the Signs of Failing Springs
Watch for these early warning signs that your garage door springs may be failing:
- Door feels unusually heavy when lifting manually
- The door closes too quickly or unevenly
- Loud bang from the garage—similar to a firecracker
- Gaps or distortions in the spring coils
- Door won’t open, even with the opener running — if you’re not sure whether the spring is the problem, see why a garage door may become stuck.
If you notice any of these symptoms, do not attempt to fix it yourself.
