Garage Door Springs in Millbrae: How Long Do They Really Last?
2026-08-25 7 min read
In our years serving Millbrae, we've seen this problem again and again: homeowners discover their garage door springs have failed only when the door won't budge. Most residential garage door springs in Millbrae last between 7 and 9 years, not the 10 or 15 some assume. The timeline depends heavily on climate, usage, and which type of spring system you have.
Why Springs Fail Faster Than You Think
Your garage door springs bear an enormous load. Every single day, whether you open that door once or twenty times, the springs compress and extend under thousands of pounds of force. Over time, metal fatigues. Tiny stress fractures develop. Then one morning, you hear a loud bang from the garage. That's a snapped spring. See our guide on garage door cost & pricing in millbrae: what homeowners actually pay.
Millbrae's coastal environment accelerates this wear. Salt air corrodes metal. Humidity cycles cause rust. Temperature swings from cool mornings to warm afternoons create expansion and contraction that weakens the steel. This isn't just a theory. We pull failed springs off doors here and see the corrosion firsthand. A spring that might last 8 years inland lasts 6 or 7 years near the coast.
The two main spring types behave differently. Torsion springs, which wind around a shaft above the door, typically outlast extension springs, which run along the sides. But both degrade at similar rates in Millbrae's salt-tinged air. If you're unsure which type you have, our detailed guide on torsion vs. extension springs breaks down the differences and what each means for longevity.

Red Flags That Your Springs Are Dying
Don't wait for a complete failure. Watch for these warning signs:
The door feels heavier than normal when you open it manually. Your garage door opener labors harder, making grinding noises. The door opens unevenly, tilting to one side. You notice visible rust, pitting, or discoloration on the springs. Small metal dust or debris appears below the spring assembly.
Any one of these signals that a spring is near the end of its life. A snapped spring isn't just inconvenient. It's dangerous. When a spring breaks, the door can fall rapidly, crushing a car, a pet, or worse. The opener's safety sensors may not catch this failure in time.

Maintenance Extends Life (But Doesn't Stop Time)
Regular lubrication and inspection slow the decline. A light coat of garage door lubricant every three months reduces friction and corrosion. Check for rust spots and wipe them clean. These habits buy you a few extra months, maybe a year, but they won't reverse metal fatigue.
Our seasonal maintenance checklist covers spring care alongside other critical tasks. Following it keeps your system running smoothly and helps you spot problems early.
When springs begin to fail, replacement is the only real option. Repair isn't viable once metal cracks. Partial repairs create safety hazards because the remaining springs must carry uneven loads. Both springs should be replaced together, even if only one has snapped. This ensures balanced operation and prevents premature failure of the remaining spring.
What Spring Replacement Costs in Millbrae
A professional spring replacement typically runs between $200 and $400 per spring, depending on whether you have torsion or extension springs. Most homes need two springs replaced at once, so budget $400 to $800. We've published a full breakdown on snapped spring replacement costs if you want specifics for your situation.
Don't attempt DIY spring replacement. The tension in these components is extreme. A spring release gone wrong has caused serious injuries, including broken bones and eye injuries. Let a trained technician handle it. Visit our services page for spring repair to see what's included.

Frequently Asked Questions
How do I know if my garage door has torsion or extension springs? Torsion springs sit horizontally on a shaft above the door. Extension springs run vertically along the upper corners of the door frame. If you're unsure, take a photo and send it to us or call (510) 738-2914.
Can I replace just one spring instead of both? No. Both springs bear the door's weight equally. Replacing one forces the remaining spring to carry extra stress, causing premature failure. Always replace both springs together for safety and balance.
How often should I lubricate my garage door springs? Apply a light lubricant spray every three months. Avoid over-lubricating, as excess oil attracts dirt and dust. Use only products designed for garage doors, not household oils.
What's the difference between a spring breaking and a spring wearing out? A snapped spring breaks suddenly with an audible bang. A worn spring shows signs of rust, corrosion, or fatigue before failure. Both require replacement, but worn springs give you warning time to plan.
Will my garage door opener still work if a spring breaks? No. A broken spring removes the mechanical counterbalance. The opener cannot lift the full weight of the door and will either stall or overheat trying. Never force the opener if a spring has failed.
