Garage door springs come in two main types: torsion and extension. Torsion springs sit above the door and twist to lift it. Extension springs run along the sides and stretch to help raise the door. Most homes in Commerce have one or the other, rarely both. Knowing which you have matters because repair costs, lifespans, and safety risks differ between them.
Torsion springs are the heavier lifters. They're mounted horizontally above your garage door opening and use torque (rotational force) to counterbalance the door's weight as it opens and closes. A single torsion spring typically lasts 7 to 9 years with normal use. When one snaps, the door usually won't open without help from the garage door opener motor, which then strains under extra load.
Torsion springs are wound very tightly and store enormous energy. This makes them effective but also dangerous if mishandled. We've seen homeowners in Commerce and surrounding areas try DIY repairs on torsion springs. That's a mistake. The moment you loosen the winding cone, the spring can unwind violently and cause serious injury or death.
Extension springs hang vertically on both sides of the door, typically one on each side. They stretch as the door lowers and contract as it rises. Extension springs are cheaper than torsion springs, often by $100 to $200 per pair. But they wear out faster, usually lasting 5 to 7 years.
When an extension spring snaps, you'll hear a loud crack. The door becomes unbalanced. One side may sag slightly. Many homeowners panic and call a technician right away, which is the right call. Extension springs can pinch fingers or collapse unexpectedly if the pulleys fail too.
Both types have safety cables that catch a snapped spring before it whips across your garage. Still, a snapped spring is not a "wait until next week" situation.
Springs fail for a few reasons. Rust accelerates failure, especially near the coast or in humid climates. Frequent cycling (opening and closing many times daily) shortens lifespan. Manufacturing defects are rare but happen. Hard water deposits in the winding can cause micro-fractures.
In Commerce, the coastal air contributes to rust. We replace snapped springs almost weekly during summer months when homeowners are using their doors more often. Temperature swings also matter. A sudden cold snap can make metal brittle and snap under normal load.
If you've noticed your door becoming harder to open, springs may be wearing out. Learn what warning signs point to spring replacement before a failure leaves you stuck in the driveway.

This is where I get blunt as an owner. Spring repair is not a weekend project. The tension is immense, the tools are specialized, and mistakes cost lives.
We use a torque wrench and a cone wrench calibrated for the exact spring size and door weight. A standard adjustable wrench will slip. A power drill will spin out of control if something catches. We've treated injuries from people who tried to DIY this job or hired an unlicensed tech cutting corners.
Springs must be matched to your door's weight, usually between 40 and 200 pounds per spring depending on size and material. Install the wrong tension, and your opener will burn out faster. Your door will slam shut or refuse to stay open.
Understand the real costs and labor involved so you can budget accurately and avoid shock at the estimate stage.
Most snapped springs can be repaired same-day. We stock both torsion and extension springs in common sizes for homes in Commerce and Long Beach. A free estimate takes 15 minutes. We'll tell you the exact cost upfront, no surprise fees at the end.
Here's what a typical estimate includes: spring type, size in inches, wire gauge, how many turns, left or right wind direction, safety cable condition, and labor time. After labor, parts, and safety cable replacement, expect to pay $250 to $450 for most residential jobs in our area.

A broken spring puts stress on the garage door opener motor. Openers are rated for doors balanced by working springs. Without that counterbalance, the motor works 10 times harder on every cycle. You'll burn out a $300 to $600 opener in months instead of years.
Your door also becomes a safety hazard. It may fall unexpectedly or close with more force than normal. If someone's hand is under it, injuries follow. The photo eye and auto-reverse safety features help, but they're not foolproof on an unbalanced door.
Most homeowners call us within 24 hours of hearing that snapped-spring crack. That's smart. The sooner we get out, the sooner you regain reliable access and avoid compounding problems.
How long do garage door springs last? Torsion springs last 7 to 9 years with normal use. Extension springs last 5 to 7 years. Lifespan depends on door cycle frequency, climate, and maintenance. Coastal areas see faster rust-related failures.
Can I open my garage door if a spring is broken? Yes, but don't rely on it long-term. The opener motor can lift an unbalanced door, but it strains the motor and risks sudden failure or collapse. Call a technician for same-day repair instead.
What's the difference between torsion and extension springs? Torsion springs mount above the door and twist to lift it. Extension springs hang vertically on the sides and stretch. Torsion springs are stronger, last longer, and cost more to replace.
Do I need both springs replaced if one breaks? If you have two springs (one on each side or a pair of torsions), both should ideally be replaced together so wear and tension match. One old and one new spring can create imbalance. We recommend this during your estimate.
Why is garage door spring repair so expensive? Spring repair requires specialized tools, exact sizing, and high-skill labor. A mistake can cause injury or property damage. Professional technicians train extensively and carry liability insurance. You're paying for safety and expertise, not just parts.
