In this blog entry, the professional Charleston garage door installation and Charleston garage door repair experts here at ProMaster Garage Charleston will detail the differences between the main types of garage door springs.
What’s the difference between torsion springs and extension springs?
- Both torsion and extension springs counterbalance the weight of garage doors
- Torsion springs are more common
- Torsion springs are mounted above the garage door
- Torsion springs twist around a metal shaft, and the spring winds up when the garage lowers, helping to lift the door when you press the opener or manually lift it
- Torsion springs last longer and are safer – but more expensive
- Extension springs run parallel to the garage floor and are attached to the rear track hanger
- Extension springs store energy by stretching as the garage door lowers, while connected to the door with a pulley and cable system
- Extension springs are cheaper, but have more parts and are slightly more dangerous due to having exposed springs and cables
What are the main signs of garage door spring failure?
- Jerky motion
- Strange noises like clanging, grinding, or screeching
- Issues lifting or lowering the garage door manually
- Visible cracks, rust, fraying, or other physical issues with the spring
What are some tips for keeping garage door springs in good shape?
- Regularly apply a silicone-based lubricant
- Check garage door balance and ensure that garage doors that are imbalanced receive professional balancing service
- Never attempt to repair or adjust garage door springs yourself!!
