Here's what most homeowners don't realize about garage door springs: they're not just backup support. They do almost all the heavy lifting. Your opener motor handles maybe 10% of the work. The springs handle the rest, counterbalancing a door that weighs 300 to 500 pounds. In Pacifica's coastal environment, where salt air corrodes metal faster than inland areas, springs wear out quicker than you'd expect. Understanding this changes everything about maintenance and repair timing.
Two main types of springs support your garage door: torsion springs and extension springs. Torsion springs sit above the door on a horizontal rod and twist as the door opens and closes. Extension springs run along the sides and stretch. Both store energy and release it to help your opener lift the door smoothly.
Most garage door springs last 7 to 9 years with regular use, assuming no salt corrosion or impact damage. In Pacifica, that timeline compresses. The ocean air attacks metal relentlessly. Springs develop micro-rust that weakens them long before you notice anything wrong. One day your door opens fine. The next day, a spring snaps without warning.
When a torsion spring snaps, the door becomes a safety hazard. It falls faster, the opener strains to compensate, and you're suddenly stuck with a heavy door you can't move by hand. Extension springs fail similarly, though sometimes you'll hear a loud bang and see the broken coil hanging loose.
Salt air doesn't just rust springs. It degrades them from the inside out. Hairline cracks form in the metal coil. Corrosion spreads along stress points where the spring is wound tightest. By year 6 or 7, many Pacifica homeowners call us for a snapped spring when inland customers might have another year left.
This is also why DIY spring replacement is dangerous. Springs hold tremendous tension. A snapped spring can whip at you with force that breaks bones. We've seen injuries. Don't attempt this yourself. Call a professional who has the right tools, the right safety equipment, and liability insurance.

Regular maintenance catches weak springs before they snap. During a tune-up, we inspect spring tension, listen for creaking, and check for visible rust or corrosion. If a spring is near the end of its life, we'll tell you straight and schedule a free quote for replacement before it fails. That's cheaper and safer than an emergency call at midnight.
A sagging door is the most obvious sign. If one side hangs lower than the other, one spring is weaker or already compromised. The door may also move jerkily, pause halfway up, or feel heavy when you manually push it. Some doors make a loud creaking noise as the remaining spring strains under full load.
Don't ignore these warnings. A failing spring can snap during normal operation, trapping your car inside or leaving your home unsecured. If you notice any of these issues, learn more about spring replacement costs and timelines so you know what to expect.
Spring replacement typically costs between $200 and $400 per spring, depending on the type and quality. A snapped spring always means replacing both springs at the same time, even if only one broke. They wear together, and replacing just one creates imbalance that stresses the other prematurely.
Same-day service is possible if you call early. We stock common spring sizes and can dispatch a truck to your Pacifica home within hours. Emergency calls after hours cost more. Scheduling ahead saves money and stress.
If you're also dealing with an older opener or considering upgrades, check out our guide on belt versus chain garage door openers to see if a full system replacement makes sense alongside spring work.
You can't stop salt air, but you can slow its damage. Spray-coat your springs with a rust inhibitor every 12 months. Keep your garage well ventilated so moisture doesn't pool around the hardware. Have your door serviced annually, especially in coastal areas. Regular maintenance tune-ups catch problems early and extend spring life by 1 to 2 years.

How long do garage door springs last in Pacifica? Typically 7 to 9 years, but coastal salt air can reduce that to 6 to 7 years. Regular inspection helps catch wear before springs snap unexpectedly.
Can I replace a garage door spring myself? No. Springs hold extreme tension and can cause serious injury or death if mishandled. Always hire a licensed professional with proper tools and safety training.
How much does a spring replacement cost? Usually $200 to $400 per spring. Most replacements involve two springs, so budget $400 to $800 total. Emergency after-hours service costs more.
What's the difference between torsion and extension springs? Torsion springs twist horizontally above the door. Extension springs stretch along the sides. Torsion springs are more common and safer in most residential doors.
Can I still use my garage door if one spring is broken? Not safely. A broken spring means the other spring carries full load, risking immediate failure. Don't operate the door. Call for emergency service right away.
