Extension Spring Repair Bridgeport, CT
Extension springs mount on either side of your garage door track and stretch to provide the lifting force needed to open your door. These springs are commonly found in older garage door systems and garages with limited headroom. Round Hill Garage Door Repair provides expert extension spring repair throughout Bridgeport, CT.
Unlike torsion springs that use torque, extension springs work by stretching and contracting. When your garage door closes, the springs extend, storing potential energy. When the door opens, this energy releases, assisting with lifting. While simpler in design, extension springs require proper maintenance and should always include safety cables to prevent injury if a spring breaks.
Understanding Extension Spring Systems
Extension springs typically come in pairs—one on each side of the door. They connect to the track assembly at one end and to cables/pulleys at the other. Safety cables run through the center of each spring, containing the spring if it breaks. If your extension springs lack safety cables, consider having them installed immediately.
Signs of Extension Spring Problems
- Spring hanging loose: A broken spring will droop or hang disconnected
- Door opens unevenly: One side lifts faster than the other
- Gaps between coils: Stretched springs show visible spacing changes
- Door slams shut: Worn springs can't control the door's descent
- Squeaking sounds: Metal-on-metal friction indicates wear
Extension Spring Safety
Safety Cable Requirement
All extension springs should have safety cables installed. These cables run through the center of each spring and attach to the wall or track. If a spring breaks, the safety cable contains it, preventing the spring from becoming a dangerous projectile. If your springs lack safety cables, have them installed immediately.
Extension vs. Torsion Springs: Which is Better?
While extension springs are more affordable upfront, torsion springs offer several advantages:
Extension Springs
- Lower initial cost
- Good for limited headroom
- Easier DIY replacement (though not recommended)
- Shorter lifespan (typically 8-12 years)
Torsion Springs
- Longer lifespan
- Smoother operation
- Better balance control
- Safer when properly installed
