Garage Door Springs in Redwood City: Cost, Types, and When to Replace
2026-08-24 7 min read
A snapped garage door spring will stop your door cold, and it's one of the most common calls we handle in Redwood City. Springs typically last 7 to 9 years depending on use, and when they fail, replacement is not optional. This guide covers the two spring types, realistic costs, and why waiting only makes the problem worse.
Understanding Your Garage Door Springs
Two types of springs support your garage door: torsion springs and extension springs. Torsion springs sit above the door on a horizontal rod and twist to lift the door. They're the more common choice and handle the load more efficiently. Extension springs run parallel to the tracks on either side and stretch to assist the opener. Both wear out, but torsion springs tend to last longer under normal conditions.
The difference matters because a snapped spring in one type requires a different replacement approach than the other. If you're unsure which you have, a photo sent to us can clarify that in seconds.
Signs Your Springs Need Attention
Your garage door will tell you when springs are weakening. Listen for a loud bang or crack sound when opening or closing. That noise often means a spring just failed. A door that moves slowly, sags on one side, or doesn't open all the way without extra force from the opener signals spring trouble ahead.
Never force a stuck door. Doing so strains the opener and can cause secondary damage that inflates your repair bill. If your door feels heavier than normal, springs are likely the culprit. We've written more about warning signs and replacement timing in our detailed spring replacement guide.
Garage Door Spring Costs in Redwood City
Spring replacement costs depend on the type and quantity. Torsion springs run between $200 to $400 per spring installed, while extension springs typically cost $150 to $300 per spring. Most residential doors use either one torsion spring (in newer homes) or two extension springs (in older installations).
If both springs have failed or are near failure, replacing them together is smart. One spring bearing all the load wears faster, so a second failure often follows within months. Labor and materials combined, expect a same-day service call in Redwood City to run $300 to $600 for a complete job done right.

Why DIY Spring Replacement Isn't Worth It
Springs are under extreme tension. A torsion spring can store enough energy to cause serious injury if mishandled. Even experienced homeowners have sustained broken bones and worse attempting to replace springs themselves. The proper tools alone cost hundreds of dollars and aren't worth buying for a one-time job.
Our technicians have the equipment, training, and insurance to do this safely. We'll also inspect your opener, tracks, and rollers while we're there. Often a spring failure reveals wear elsewhere that preventive maintenance could have caught earlier.

Getting the Right Spring the First Time
Not all springs are created equal. Using undersized or low-quality springs leads to premature failure and opens the door to opener damage. We source springs rated for your specific door weight and installation type. That precision prevents the cycle of repeat failures that drain your wallet.
When we arrive for your service, we'll verify the exact spring model, measure the door weight, and confirm you're getting the right replacement. This attention to detail is what separates a quick fix from a lasting solution. Our full services list outlines exactly what's included in spring replacement.
Timing Matters
A broken spring strands your vehicle inside until it's fixed. If you work from home or have a second vehicle, you might delay. But waiting lets the door sit idle, which can cause track misalignment and opener strain. The sooner you address it, the lower your total repair cost.
We handle spring replacements across Redwood City and the surrounding Peninsula area. Most calls are resolved the same day you contact us. Don't let a stuck door disrupt your routine longer than necessary.
Your garage door springs are working right now, under thousands of pounds of pressure, to lift and lower that door safely. When they start to fail, trust the job to someone who understands their importance. Garage Door Redwood City has been handling spring replacements for years, and we get it right every time.
Spring failure is frustrating but fixable. Call 510-822-6775 today or get a same-day estimate to move forward. We'll have you back in action quickly.
Frequently Asked Questions
How do I know if my garage door spring is broken? A loud bang when opening or closing, a door that won't open smoothly, or one that sags to one side all signal spring failure. If you hear the sound but the door still moves, one spring may have failed while the other still holds. Stop using the door and call for service immediately.
Can one broken spring be replaced, or must I replace both? You can replace one, but if the other is the same age and type, it's likely near failure too. Replacing both at once costs more upfront but saves you from a second service call within months. We recommend replacing pairs for residential doors.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal residential use. Extension springs may fail sooner, especially in older installations. Frequency of use, climate, and maintenance all affect lifespan. Regular upkeep extends spring life.
Why is spring replacement so expensive? Springs operate under extreme tension, requiring specialized tools and expertise to replace safely. Labor accounts for much of the cost because this is dangerous work. Cheap springs also fail faster, making the investment in quality parts worthwhile.
Will my garage door opener work if the spring is broken? No. The opener cannot lift the door without spring assistance. Forcing it will burn out the opener motor and cause expensive secondary damage. Always call for spring repair before attempting to use the opener again.
