Garage door springs are the unsung heroes of your garage door system. They counterbalance the door's weight, making it possible to open a 150-300 pound door with minimal effort. When springs fail, your door becomes inoperable.and attempting DIY replacement can be extremely dangerous. Here's what every homeowner should know about garage door springs.
Located above the door on a metal shaft, torsion springs twist to store mechanical energy. When the door opens, this stored energy helps lift the door. Torsion springs are the most common type in modern residential installations because they're:
- Safer than extension springs (contained on a shaft) - Longer-lasting (typically 15,000-20,000 cycles) - Smoother in operation, Available in various sizes for different door weights
Most residential torsion springs are rated for about 10,000 cycles (one cycle = one open + one close). High-cycle springs rated for 25,000-100,000 cycles are available for an additional cost.
Found along the horizontal tracks on either side of the door, extension springs stretch to store energy. While less expensive than torsion springs, they have several disadvantages:
- Higher risk of flying parts if they break, Shorter lifespan, Less smooth operation, Safety cables should always be installed through them
If you have extension springs and they break, consider upgrading to a torsion spring system for improved safety and longevity.
When you disconnect the opener and lift the door manually, it should stay in place at any height. If it falls or rises on its own, the springs have lost tension and need adjustment or replacement.
Torsion springs break by separating into two pieces. If you see a gap in your spring, it has broken and needs immediate replacement.
A properly balanced door should feel light.maybe 10-20 pounds of lift effort. If it feels significantly heavier, the springs aren't doing their job.
Many homeowners first discover a broken spring when they hear a loud bang (like a firecracker) from the garage. That's the sound of the spring breaking and releasing its tension.
If your opener seems to be working harder than usual, making straining noises, or failing to fully open the door, worn springs could be the culprit.
When only one spring breaks (in a two-spring system), the door may rise crookedly or jam in the tracks.
We cannot stress this enough: garage door spring replacement is not a DIY project. Here's why:
Torsion springs can store enough energy to cause serious injury or death. A standard two-car garage door spring is under approximately 100-200 foot-pounds of torque. Special tools and training are required to safely release and apply this tension.
Professional technicians use winding bars, spring pullers, and other specialized tools designed for safe spring work. Improvised tools (like screwdrivers) can slip out of the spring cone, causing the spring to spin violently.
Springs must be precisely matched to your door's weight and dimensions. The wrong spring will cause poor balance, premature wear, and potential damage to other components.
DIY spring work often voids garage door warranties and may not be covered by homeowner's insurance if injuries or damage occur.
A professional spring replacement typically takes 1-2 hours and includes:
1. Safety assessment of the entire door system 2. Careful release of tension from broken springs 3. Removal of old springs 4. Installation of new springs matched to your door 5. Balancing and adjustment 6. Lubrication of springs and other components 7. Safety testing of the complete system
While springs eventually wear out, you can maximize their lifespan:
- Annual lubrication: Apply garage door lubricant to springs yearly - Regular balance checks: Test balance twice a year - Prompt repairs: Fix other problems quickly to prevent strain on springs - Quality springs: When replacing, consider high-cycle springs for longer life
Spring replacement costs vary based on spring type, door size, and whether you need one or both springs replaced. Generally, expect $150-$350 for a single spring replacement and $200-$500 for a pair, including professional installation.
Important note: Even if only one spring breaks, we recommend replacing both at the same time. If one has failed, the other is likely nearing the end of its life, and replacing both together saves on service call costs.
