Garage Door Springs in Mission Viejo: Torsion vs. Extension Explained
2026-08-01 7 min read
Your garage door relies on springs to lift and lower safely, yet most homeowners don't know which type they have or how long they'll last. Torsion and extension springs both counterbalance your door's weight, but they work differently, fail differently, and cost different amounts to replace. Knowing the difference saves you money and keeps your door running smoothly.
Torsion Springs vs. Extension Springs
Torsion springs twist and coil above your door opening. They store energy through rotational force, which makes them efficient and compact. Most modern residential doors in Mission Viejo use torsion springs because they're safer, quieter, and more durable than their counterparts.
Extension springs run horizontally along the sides of your door opening. They stretch and contract to help lift the door. Older homes and lighter-duty doors often use extension springs. They're cheaper upfront but wear out faster and pose greater safety risks if they snap without a safety cable.
The practical difference matters. Torsion springs last 7 to 9 years with normal use. Extension springs typically last 5 to 7 years. If your door is older or you use it frequently, springs fail sooner. Orange County weather, with its heat and occasional humidity swings, can also shorten spring life by a year or two.
Why Springs Snap and How to Know
A snapped spring usually announces itself loudly. Your door becomes heavy to operate or won't open past a few inches. You might hear a loud bang or crack from the garage. Don't force a stuck door. A snapped spring means the opener is working without spring support, which strains the motor and risks injury.
Springs fail for predictable reasons. Rust weakens metal over time. Lack of lubrication increases friction and wear. Repeated cycles of expansion and contraction eventually exhaust the metal's strength. Regular maintenance extends spring life, but replacement is unavoidable.
