Garage Door Spring Types in Bellingham: Torsion vs. Extension Explained
2026-08-15 7 min read
Your garage door hangs on springs that do 99 percent of the heavy lifting. Most homeowners don't know which type they have until one fails. The two main kinds are torsion and extension springs, and knowing the difference can save you money and headaches when something breaks.
What's the Difference Between Torsion and Extension Springs?
Torsion springs sit on a metal shaft above your garage door opening. They twist and unwind to lift the door's weight. One torsion spring can handle 400 to 500 pounds of force. Extension springs run horizontally along the sides of the door frame and stretch as the door opens. Most homes use one of these two, though some older setups might have both. See our guide on garage door installation in bellingham: what homeowners don.
Torsion springs are more common in Bellingham and the Pacific Northwest because they're smoother, quieter, and last longer. They typically survive 7 to 9 years with average use. Extension springs are cheaper upfront but tend to wear out faster, usually around 5 to 7 years. They're also noisier and put more stress on your opener.
Why Torsion Springs Are Safer
Extension springs have safety cables running through the center. If a spring snaps, the cable catches it. Without that cable, a broken extension spring can whip across your garage like a weapon. Torsion springs don't need cables because the shaft contains the force. If one breaks, it simply unwinds. This is one reason why replacing torsion springs is considered safer work, though it still requires professional tools and knowledge. Read about how bellingham.
Cost, Lifespan, and When to Replace
A single torsion spring costs more upfront than an extension spring. Torsion replacements in Bellingham typically run 150 to 250 dollars per spring, while extension springs cost 75 to 150 dollars each. Most doors need two springs replaced at the same time. Yes, both. Even if only one snapped, the other has lived the same lifespan and will fail soon after.
Springs don't last forever. The cycle count matters: each open and close counts as one cycle. A spring rated for 10,000 cycles will fail faster if your door opens and closes 10 times a day versus 3 times a day. Professional maintenance can extend spring life by reducing friction and catching early wear.

Frequently Asked Questions
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal use. Extension springs wear out faster at 5 to 7 years. Lifespan depends on cycle count, maintenance, climate, and door weight. Bellingham's damp climate can accelerate rust and wear if springs aren't lubricated regularly.
Can I replace just one spring? No. Even if only one spring broke, both have lived the same lifespan. The second will fail very soon. Always replace both springs together. This prevents door imbalance and keeps your opener from working too hard.
What does a snapped spring sound like? A loud, sharp bang or crack. The door suddenly becomes heavy and won't open. Some people mistake it for a gunshot. If this happens, stop trying to open the door and call us right away.
Is spring replacement covered by warranty? Springs themselves have limited warranties, usually 1 to 2 years on parts. Most wear and tear isn't covered. Our labor comes with our guarantee. Ask about that when you call.
Why do extension springs need cables but torsion springs don't? Extension springs stretch under tension. If they snap, the spring uncoils violently. Safety cables catch a broken spring before it flies free. Torsion springs twist instead of stretch, so the shaft contains the energy if they fail. This makes torsion safer overall.
