Here's what most homeowners don't realize about garage door springs: they're doing almost all the heavy lifting. Your garage door weighs 300 to 500 pounds. Those springs counterbalance that entire load every single time you open or close. They fail silently, then suddenly your door won't budge. In Pacifica, where coastal salt air accelerates corrosion, springs typically last 7 to 9 years instead of the 10 to 15 you might expect inland. Understanding when they need replacement saves you from emergency calls and keeps your family safe.
Your door uses one of two spring types: torsion springs (horizontal, mounted above the door) or extension springs (vertical, mounted on each side). Torsion springs are far more common in modern homes and handle the load more efficiently. Think of a spring as a coiled battery. Every cycle winds it tighter, storing and releasing energy. Over time, metal fatigues. The spring weakens. One day it snaps.
A snapped spring means your opener can't lift the door. The door becomes a dead weight. You're stuck. And that's when most homeowners call for emergency service.
Don't wait for a snap. Watch for these red flags. The door feels heavy when you manually lift it. The opener struggles or makes grinding sounds. You see a visible gap in a torsion spring (if you can safely peek). The door moves unevenly, tilting to one side.
One spring failure often triggers the second spring to fail within weeks. They wear at nearly identical rates. Smart homeowners replace both springs at once, even if only one has snapped. This prevents a second emergency call and saves money on labor.
If your door has other wear patterns, review our guide on garage door maintenance tune-up in Pacifica to catch problems early.

A single torsion spring replacement runs $150 to $300, including labor. Both springs together cost $250 to $500. That estimate depends on spring size, your door's weight, and local labor rates. Extension springs are slightly cheaper to replace but less common in Pacifica homes.
Parts are inexpensive. A torsion spring itself costs $30 to $80. Labor is where the cost sits because this job requires specialized tools and knowledge. A misstep with a compressed spring can cause serious injury. This is not a DIY task.
Timeline matters. If you call before noon on a weekday, same-day installation is usually possible. Weekends and evenings take longer. Emergency calls after hours carry premiums. The actual replacement takes one to two hours once the technician arrives.

Salt air corrodes metal. Pacifica sits on the coast, exposed to Pacific moisture and salt spray year-round. This accelerates spring deterioration compared to inland areas like Glendale or Pasadena. Springs that last 10 years inland may last only 7 to 9 years here. Regular maintenance reduces corrosion, but can't eliminate it.
Inspect your springs annually. Look for rust, pitting, or discoloration. A light coating of oil (not WD-40, which attracts dust) helps slow decay. Visit our garage door maintenance guide for Pacifica for seasonal care steps.
Spring replacement demands professional tools: a spring winder, proper safety cables, and knowledge of your door's specific spring size. Springs are under extreme tension. A released spring can cause lacerations or broken bones. Garage Door Pacifica technicians have 15 years of on-truck experience handling these jobs safely and quickly.

How do I know if my garage door spring is broken? The door won't open or feels extremely heavy when you try to lift it manually. You may hear a loud bang or snap. A visible gap or separation in the spring coil is a dead giveaway. Stop using the door and call a technician immediately.
Can I replace a garage door spring myself? Springs are under 200+ pounds of tension. A slip can cause serious injury. Professional replacement takes 1-2 hours and costs $250-$500 for both springs. DIY attempts lead to emergency room visits and larger bills. Not worth the risk.
How long do garage door springs last? Torsion springs last 7 to 9 years in Pacifica's coastal climate, sometimes 10 to 15 years inland. Extension springs last slightly shorter. Lifespan depends on usage frequency, maintenance, and environmental corrosion. More cycles mean faster wear.
What's the difference between torsion and extension springs? Torsion springs are horizontal, above the door. They handle load more efficiently and last longer. Extension springs are vertical, on each side, and are less common in newer homes. Torsion is the modern standard for residential doors.
Should I replace both springs if only one breaks? Yes. Both springs experience identical wear. The second one will fail within weeks. Replacing both at once saves you a second service call, labor cost, and downtime. It's the smarter move.
