Garage Door Spring Types in Blanco: Torsion vs. Extension Explained
2026-07-18 7 min read
Your garage door relies on one of two spring types to lift that 300+ pound panel safely. Torsion springs twist to store energy. Extension springs stretch along the sides. Both fail eventually, but they break differently, cost differently, and need different repair approaches. Understanding which one you have saves money and prevents dangerous mistakes.
Which Spring Type Do You Have?
Look inside your garage without opening the door. Torsion springs sit horizontally above the door opening, usually centered. They look like metal coils wound tightly around a steel rod. Extension springs run vertically along both sides of the door, parallel to the vertical tracks. They resemble long metal coils that stretch when the door opens.
Torsion springs are standard in most modern homes, especially in Blanco and nearby Johnson City. They're more durable and safer because they're contained above the door. Extension springs are older, cheaper upfront, but they're more prone to sudden failure. If your home was built before 1990, you likely have extension springs. Newer construction typically uses torsion.
Why Torsion Springs Last Longer
Torsion springs typically last 7 to 9 years with normal use. A single spring handles all the lifting force, distributing stress evenly over time. The enclosed design above the door also protects them from dust, moisture, and temperature swings that corrode metal faster.
Extension springs, by contrast, usually wear out in 5 to 7 years. Each side bears half the load, but they're exposed to the elements. Summer heat in Blanco and winter cold cause metal to expand and contract. That constant stress weakens the coils faster. When an extension spring snaps, the door drops suddenly and can injure someone below.

Cost Comparison: Which Type Is Actually Cheaper?
A torsion spring replacement costs $200 to $350 per spring, including labor. Most doors have one torsion spring, so budget $250 to $400 total. Extension springs run $150 to $250 each, and you need two, so $300 to $500 for parts. But here's the catch: because extension springs fail more often, you'll replace them twice while replacing torsion springs once over a 15-year span.
The math favors torsion. You pay more upfront but save $300 to $500 over the life of your garage door. Blanco Garage Doors can provide a free estimate for either type, so you'll know exactly what your specific door costs before committing.
Replacing the Wrong Spring Type Is Dangerous
Never attempt a DIY replacement. Springs hold enormous tension. A torsion spring can snap and cause serious injury. Extension springs can recoil violently if the cable breaks during removal. Professionals use safety equipment and specialized tools.
More importantly, installing the wrong spring type or size throws off the door's balance. An unbalanced door strains the opener, shortens its lifespan, and can fail to close properly. In Blanco's heat, a malfunctioning door left open invites pests and wastes air conditioning dollars.
When to Replace Springs Proactively
Don't wait for a spring to snap. If your door is 8+ years old and uses torsion springs, or 6+ years with extension springs, schedule an inspection. A technician can spot stress cracks and worn coils before failure. Proactive replacement costs the same but prevents emergency service fees.

Signs Your Spring Is About to Fail
Listen for loud banging or popping sounds when opening or closing. The door may move slower than usual or feel heavier. Sometimes the door won't stay open and slowly creeps closed, even when you prop it. These symptoms mean the spring is losing strength and failure is near.
If the door suddenly won't move at all, a spring has likely snapped. Don't force the opener. Call for emergency service right away. Our 24/7 emergency team responds quickly across the Blanco area.
The Bottom Line
Torsion springs are the modern, safer, and more economical choice over 15 years. Extension springs are cheaper upfront but fail faster and pose more safety risks. Whatever type you have, professional replacement is essential.
Your garage door's safety and your wallet both depend on acting fast when springs wear out. Don't guess about repair costs or timelines. Call Blanco Garage Doors at (830) 532-8066 for a same-day estimate on spring replacement, or visit our services page to learn more about what we offer.
Frequently Asked Questions
How do I know if my garage door spring is broken? The door won't open or will drop quickly when you release it. You may hear a loud bang before the door stops responding. If the door feels unusually heavy or moves in jerks, the spring is failing and needs immediate attention.
Can I replace just one torsion spring? Technically yes, but professionals recommend replacing both springs even if only one is broken. Springs age together, so the remaining one will fail soon after. Replacing both avoids a second service call and keeps the door balanced.
How much does a garage door spring replacement cost in Blanco? Torsion springs run $250 to $400 installed. Extension springs cost $300 to $500 for both. Labor and spring quality affect the final price. Call us for a free estimate specific to your door.
Is it safe to use my garage door if the spring is broken? No. Never operate a door with a broken spring. The opener can't lift the full weight, and the door may jam or drop unexpectedly. This risks injury and damage to the opener.
How often should garage door springs be replaced? Torsion springs last 7 to 9 years with normal use. Extension springs last 5 to 7 years. Frequency depends on how often you open and close the door and local climate conditions.
