Understanding Extension Spring Systems
Extension springs are one of two main types of garage door spring systems, commonly found in older Portland homes and on lighter, single-car garage doors. Unlike torsion springs that mount above the door, extension springs run along the horizontal tracks on either side of your door. These springs work by stretching and contracting - when your door closes, the springs stretch to store energy, and when the door opens, they contract to help lift the weight. Each spring is connected to the door through a pulley and cable system.
Extension springs are a cost-effective, reliable solution for garage doors, particularly lighter doors or those with limited headroom above the door opening. While they don't last quite as long as torsion springs and require more frequent replacement, they're less expensive and easier to install. Many Portland homeowners with extension spring systems find them perfectly adequate for their needs, especially when properly maintained and equipped with safety cables.
Important: Safety Cables Are Essential
If your extension springs don't have safety cables running through them, your garage door system is dangerous. When an extension spring breaks, it can fly across the garage with tremendous force, causing serious injury or property damage. Safety cables prevent this by containing the broken spring.
We include safety cables with every extension spring replacement at no extra charge. If your Portland home has extension springs without safety cables, contact us to have them installed immediately. This simple safety feature could prevent a serious accident.
Extension Springs vs. Torsion Springs
Extension Spring Advantages
- Lower initial cost for parts and installation
- Simpler design with fewer components
- Works well for lighter, single-car doors
- Easier to install in garages with limited headroom
Torsion Spring Advantages
- Longer lifespan (15,000-20,000 vs. 10,000 cycles)
- Smoother, more balanced door operation
- Safer design with springs contained above door
- Better for heavier, two-car garage doors
If you're replacing extension springs on your Portland home, we can discuss whether upgrading to a torsion system makes sense for your situation. While torsion systems cost more initially, they may be more cost-effective long-term due to their longer lifespan and superior performance.
Signs Your Extension Springs Need Replacement
Visible Damage or Separation
Look at your extension springs when the door is closed (when they're stretched). If you see any gaps, breaks, or separated coils, the spring has failed and needs immediate replacement. Do not operate the door if you see spring damage.
Door Won't Open Fully
If your door won't open all the way or struggles to lift, one or both extension springs may be broken or losing tension. The opener motor cannot lift the full weight of the door without functioning springs.
Uneven Door Movement
If one extension spring is broken or weaker than the other, your door may open unevenly or appear crooked. This creates dangerous imbalance and additional stress on your opener and door components.
Excessive Rust or Corrosion
Portland's moist climate can cause rust on extension springs, especially if they're not regularly lubricated. Significant rust weakens the spring and indicates it's nearing the end of its lifespan. Consider replacement before the spring breaks unexpectedly.
