Garage Door Springs in Palo Alto: Torsion vs. Extension and What They Cost
2026-08-08 A2Z Garage Doors
Let's cut through the confusion about garage door springs. The two types serving Palo Alto homes are torsion and extension springs. Torsion springs sit above your door and twist to lift it. Extension springs run along the sides and stretch under load. Understanding the difference saves you money and prevents dangerous mistakes when something snaps.
What Are Torsion Springs and How Do They Work?
Torsion springs are the workhorse of modern garage doors. They're mounted horizontally above the door opening and wind tightly to store mechanical energy. When you open the door, that stored tension unwinds slowly, counteracting the door's weight. Most residential doors in Palo Alto use one or two torsion springs, depending on door weight.
The beauty of torsion springs is their precision. They're engineered for your specific door weight and height. A snapped spring means the door won't open at all. You'll hear a loud bang from your garage if a spring fails suddenly. That sound is the spring's stored energy releasing all at once. Never attempt to replace a snapped torsion spring yourself. The tension is dangerous, and improper installation can damage your opener or door.
Extension Springs: The Older Alternative
Extension springs are simpler mechanically but less common in newer Palo Alto homes. They extend and contract along the sides of the door frame, pulling cables that lift the door. If one extension spring snaps, the other takes the full load, straining your opener and door. This asymmetry can bend the door or damage the frame.
Extension springs last 7 to 9 years on average. They fail more gradually than torsion springs, sometimes showing warning signs like slower opening. Because they're side-mounted, they're slightly easier to replace than torsion springs. Still, you should hire a professional. The cables remain under tension even after the spring breaks.

Preventing Future Spring Failures
Once springs are replaced, keep them healthy. Lubricate the springs and cables annually with garage door lubricant (not WD-40, which attracts dust). Avoid slamming the door or using it roughly. Keep the area around the springs clear of clutter.
If you haven't replaced springs in over 8 years, budget for replacement soon. Springs don't last forever, and waiting for a failure puts you in a bind. A proactive replacement at a convenient time costs less stress than an emergency call at 7 AM on a weekend.
Your garage door springs deserve attention. Don't overpay for panic repairs when planning ahead keeps costs down and your door reliable.
Frequently Asked Questions
How long do garage door springs last? Torsion and extension springs typically last 7 to 9 years with regular use. Lifespan depends on door usage frequency, maintenance, and climate. Palo Alto's mild weather is gentler on springs than hotter regions.
Can I replace a garage door spring myself? No. Both torsion and extension springs are under extreme tension and can cause serious injury if mishandled. Always hire a licensed technician for replacement or adjustment work.
What's the difference between torsion and extension springs? Torsion springs twist above the door; extension springs stretch along the sides. Torsion springs are more reliable and precise. Most modern Palo Alto homes use torsion springs in pairs.
How much does spring replacement cost near me? In Palo Alto, expect $200 to $400 for torsion spring replacement and $150 to $300 for extension springs. Cost varies by door weight, spring size, and whether both springs need replacement.
How do I know if my spring is broken? A snapped spring causes a loud bang. After that, your door won't open, or it opens very slowly. If the door opens unevenly or feels heavier than usual, springs are wearing out and need inspection soon.
