Your garage door springs are arguably the most important.and potentially dangerous.components of your garage door system. These tightly wound metal springs bear the full weight of your door, which can range from 150 to over 400 pounds. Understanding how they work and respecting their power is essential for every homeowner.
Garage doors use one of two types of spring systems:
Torsion Springs Located horizontally above the garage door opening, torsion springs wind and unwind to raise and lower the door. They're mounted on a metal shaft and use torque to balance the door's weight. Most modern garage doors use torsion springs because they: - Provide smoother, more controlled movement, Last longer than extension springs, Are considered safer when properly installed, Allow for better door balance
Extension Springs These springs run parallel to the horizontal tracks on each side of the door. They stretch and contract as the door moves. While less expensive than torsion springs, extension springs: - Wear out faster, Can be more dangerous if they break (the spring can fly across the garage) - Require safety cables to prevent injury if they snap
Springs don't last forever. Most residential garage door springs are rated for about 10,000 cycles (one cycle = one opening and closing). Here are warning signs of spring problems:
For Torsion Springs: - Visible gap in the spring (it's broken) - Door feels heavy when lifting manually, Door won't stay open halfway (balance test failure) - Loud bang from the garage (spring breaking) - Door opens a few inches then stops
For Extension Springs: - Obvious stretching or gaps in the coils, Door appears crooked or uneven, Excessive noise during operation, Springs appear longer than they used to
We cannot stress this enough: garage door spring repair should only be performed by trained professionals. Here's why:
Extreme Tension Torsion springs are wound with incredible force.enough to lift a door weighing hundreds of pounds. If released improperly, this stored energy can cause serious injury or death. Every year, homeowners are injured attempting DIY spring repairs.
Specialized Tools Required Proper spring replacement requires winding bars, vise grips, and other specialized tools. Using the wrong tools can cause the spring to release unexpectedly.
Precision is Critical Springs must be wound to exact specifications based on your door's weight and height. Incorrect tension causes operational problems and premature wear on other components.
One-Piece Doors are Especially Dangerous If you have an older one-piece garage door, the spring systems are even more hazardous. Never attempt any repairs on these systems yourself.
If you hear a loud bang from your garage or discover your door won't open:
1. Don't try to open the door: Without spring tension, the full weight of the door is on the opener and cables, which aren't designed to bear it alone.
2. Disconnect the opener: Pull the emergency release cord to disconnect the opener from the door. This prevents motor burnout.
3. Don't force it: Trying to manually open a door with broken springs can damage the door, tracks, and cables.and risk injury.
4. Call a professional immediately: Broken springs are a safety and security issue. Most reputable companies offer same-day emergency service.
5. Keep everyone away: Until the door is repaired, keep children and pets away from the garage.
While springs will eventually wear out, you can maximize their lifespan:
- Regular lubrication: Apply garage door lubricant to springs every few months - Annual professional inspection: A technician can spot wear before failure - Balance testing: Have balance checked annually; an unbalanced door stresses springs - Minimize cycles: Each opening and closing uses one cycle - Consider high-cycle springs: When replacing, invest in springs rated for 25,000+ cycles
When selecting a company for spring repair:
- Verify they're licensed and insured, Ask about their technicians' training and experience, Request a written estimate before work begins, Inquire about spring quality and warranty, Check reviews from previous customers
