In our years serving Albertson, we've seen this problem again and again: homeowners don't know what type of spring supports their garage door until one snaps. Torsion and extension springs do the same job but in completely different ways. Understanding which you have, how they work, and why they fail could save you money and keep your family safe.
Springs counterbalance your garage door's weight, typically 300 to 500 pounds. Without them, your opener would burn out in months trying to lift dead weight. Springs store energy when the door closes and release it when you open. This simple system is what makes a 1/3 horsepower opener capable of lifting a heavy door smoothly.
The problem is that springs wear out. They're under constant tension, cycling thousands of times per year. After 7 to 9 years of normal use, metal fatigue takes hold. That's when catastrophic failure happens.
Torsion springs sit horizontally above your garage door opening, mounted on a shaft. They twist (or torque) to lift the door. When you open the door, the spring winds up tighter. When you close it, the spring unwinds, controlling the descent.
Most homes built after 1990 use torsion springs. They're safer, more durable, and last longer than extension springs. A quality torsion spring lasts 15,000 to 20,000 cycles, which translates to roughly 7 to 9 years with average use.
Torsion springs come in different wire gauges and wind patterns. A professional needs to measure the door's weight and calculate the exact spring size. Installing the wrong torsion spring can cause the door to rise too quickly or fall too slowly, both dangerous scenarios.
When a torsion spring snaps, you'll hear a loud bang. The door becomes immovable unless your opener has backup power (which most don't). The spring end whips around under the shaft, creating a serious injury hazard. This is why we always recommend calling a professional immediately. Learn what to do if yours snaps here.
Rust, metal fatigue, and poor maintenance cause most failures. In coastal areas like southeastern North Carolina, salt air accelerates rust. If your door sits in direct sunlight or gets exposed to temperature swings, the metal expands and contracts, weakening the coils over time.
Extension springs hang vertically on both sides of the door. They stretch when the door lowers and contract when it rises. Many homes built before 1990 still use extension springs.
Extension springs are cheaper upfront but shorter-lived. They typically handle 10,000 cycles before needing replacement. Because they're under constant tension even when the door is closed, they deteriorate faster than torsion springs.
The biggest safety issue with extension springs is cable breakage. When an extension spring snaps, the cable can whip across the garage, striking anything in its path. We've seen property damage and injuries from this. Modern extension spring installations include safety cables threaded through the springs to contain them if they break, but older installations often lack this protection.

Torsion spring replacement typically costs between $200 and $400 per spring, depending on size and quality. Extension springs run $150 to $250. Labor adds another $150 to $300 since this work requires special tools and expertise.
If you're facing a snapped spring and wondering about cost, remember that DIY replacement is dangerous. The springs are under hundreds of pounds of tension. A slip means serious injury. Professional installation includes a warranty and peace of mind.
Some homeowners ask about upgrading from extension to torsion springs. It's possible but requires structural modifications and new hardware. Get a free estimate from Albertson Garage Doors to compare your repair versus replace options.
Both spring types benefit from regular lubrication. Apply silicone spray to the springs and shaft every three months. Don't use WD40 or oil-based products; they attract dirt and gum up the mechanism.
Inspect your springs monthly for signs of wear. Look for rust, oil leaks from the coils, or visible gaps in the wind pattern. If you notice the door rising unevenly or closing faster on one side, a spring is likely weakening.

Albertson's humid subtropical climate accelerates rust. Springs fail faster here than in drier regions. We recommend checking springs annually rather than waiting for visible damage. Homeowners in nearby Wilmington face the same salt air challenges, so coastal maintenance matters.
Springs don't last forever. When yours fails, call immediately. A stuck garage door isn't just inconvenient; it's a security issue. Your car is trapped inside, and the opening is unprotected.
Albertson Garage Doors handles emergency spring replacement same-day when you call before 2 p.m. We stock both torsion and extension springs in common sizes. Call +1 910 946 5589 or contact us online to get a technician to your home quickly.
Springs are metal under tension. Respect that. Don't attempt repair yourself. Let professionals handle it safely.
What's the difference between torsion and extension springs? Torsion springs twist horizontally above the door opening; extension springs stretch vertically on each side. Torsion springs are safer, last longer, and are standard in newer homes. Extension springs are cheaper but riskier if they break without safety cables.
How long do garage door springs last? Torsion springs typically last 7 to 9 years or 15,000 to 20,000 cycles. Extension springs last 5 to 7 years or roughly 10,000 cycles. Lifespan depends on use frequency, climate, and maintenance.
Can I replace a garage door spring myself? No. Springs are under 300 to 500 pounds of tension. A slip or miscalculation causes serious injury or death. Professional replacement is essential. Tools, knowledge, and insurance matter here.
Why did my spring snap without warning? Metal fatigue is gradual. Tiny cracks form over years before complete failure. Rust, temperature changes, and constant cycling weaken the coils. Annual inspections catch deterioration early.
How much does spring replacement cost near me? Torsion spring replacement runs $200 to $400 per spring plus labor. Extension springs cost $150 to $250 plus labor. Exact pricing depends on your door size and spring type. Call +1 910 946 5589 for a same-day estimate.
