Garage door springs come in two main types: torsion and extension. Torsion springs sit above your door and twist to lift the weight. Extension springs run along the sides and stretch. Most Denton homes use torsion because they're safer, last longer (7 to 9 years), and handle repeated cycles better. If your door feels heavy, won't open, or you hear a loud snap, your springs likely need replacing soon.
I've responded to countless emergency calls where a homeowner ignored early warning signs. A snapped spring doesn't just inconvenience you; it can drop a 400-pound door on your car, your kid's bike, or worse.
Springs wear out because they cycle thousands of times. Every opening and closing fatigues the metal. Rust accelerates failure, especially in Texas humidity. Cold weather can snap a weakened spring instantly. If you notice your door opening slower than usual, jerking unevenly, or making creaking sounds, call us immediately.
Extension springs come with safety cables because they can whip violently when they break. Torsion springs rarely snap catastrophically, but they do lose tension gradually. Either way, a broken spring means your door won't open without serious strain on the opener.
Torsion springs are mounted on a shaft above the door center. They look like horizontal coils and handle heavier doors (most residential and commercial applications). Replacement cost runs higher but lifespan justifies it. If you need professional guidance on what's installed, our team at Denton Garage Doors can assess your setup and provide an estimate during your visit.
Extension springs hang vertically on each side of the door track. They're cheaper upfront but wear faster and pose more safety risk if they snap. Many older Denton homes still have extension springs; if that's you, upgrading to torsion during replacement makes sense for long-term safety.
The easiest way to tell: look above your door. See a horizontal coil with a cable running through it? Torsion. See springs running lengthwise along the tracks? Extension.

Springs cannot be repaired. Once they lose tension or snap, replacement is the only safe option. I've seen homeowners try to "tighten" a loose spring with a wrench; that's how fingers and hands get crushed.
A single broken torsion spring usually means both springs should be replaced. They wear as a pair, and replacing only one creates imbalance. Your door will operate unevenly and strain the opener.

If your door won't open at all, read our guide on snapped springs in Denton and why DIY attempts fail. It covers real injury scenarios and true costs.
A new torsion spring typically runs $150 to $250 per spring, plus labor. Most homes need both replaced simultaneously, so budget $400 to $600 installed. Extension springs cost less (springs alone) but labor is similar.
Same-day service is available if you call before 2 p.m. Emergency calls after hours carry an additional fee; see our after-hours emergency service page for pricing and availability.
Don't confuse spring replacement with full door replacement. A new spring breathes life into an otherwise solid door. Keeping springs maintained also reduces strain on your garage door opener, which we've covered separately if you're curious about belt versus chain openers in Denton.
Springs last 7 to 9 years with normal use (roughly 10,000 cycles). Lubricate the spring, hinges, and tracks annually with silicone spray. Keep the area around your springs clear of debris. Never attempt to adjust or replace springs yourself; the tension can cause serious injury.
Schedule a tune-up every 12 months. During a maintenance visit, we'll check spring condition, measure tension, and alert you before failure happens. That's far cheaper and safer than an emergency breakdown.

Broken springs aren't something to put off. They affect every other component in your door system and pose genuine safety risks. Act fast, get a professional diagnosis, and replace both springs together.
How long do garage door springs last? Torsion springs typically last 7 to 9 years with normal residential use. Extension springs wear faster, often 5 to 7 years. Lifespan depends on cycle frequency, maintenance, and climate conditions.
Can I replace just one spring? No. Springs wear as a pair and operate under equal tension. Replacing only one creates imbalance, causes uneven door movement, and strains the opener. Always replace both simultaneously.
What's the difference between a broken and loose spring? A snapped spring loses all tension instantly; your door becomes heavy and won't open normally. A loose spring gradually loses tension, making your door feel sluggish. Either requires professional replacement soon.
Is spring replacement expensive compared to a new door? No. Spring replacement costs $400 to $600 installed. A new garage door runs $1,500 to $4,000 or more. Springs are one of the most cost-effective repairs to extend your door's life.
Why does my door jerk to one side when opening? Uneven spring tension causes one side to lift faster than the other. This can mean one spring is weakening or already broken. Call for immediate inspection to prevent door damage or safety hazards.
