Garage Door Springs in Lewisville: Torsion vs. Extension (2026 Guide)

2026-07-19 7 min read

A customer called last Tuesday asking why her garage door felt "heavier" than usual. Within five minutes of walking into her garage, I spotted the culprit: one of her two torsion springs was about to snap. She had no idea there were two springs doing the heavy lifting, or that they come in different types. That conversation sparked this guide, because garage door springs in Lewisville deserve straight talk.

Your garage door weighs 300 to 400 pounds. Springs don't lift it by magic. They store and release tension thousands of times per year. Understanding which type you have, how they work, and when they fail will save you money, confusion, and a stuck door in the driveway.

Torsion Springs vs. Extension Springs

Torsion springs sit on a metal rod above your door opening. They wind up like a clock spring, then unwind to counterbalance the door's weight as it opens. Most homes built after 1980 use torsion springs because they're safer, last longer, and operate more smoothly. They typically last 7 to 9 years with average use (200 to 300 open/close cycles per week).

Extension springs hang vertically along the sides of the door opening. They stretch and contract like a slinky. Older homes and some budget installations use extension springs, which wear out faster (usually 5 to 7 years) and carry higher injury risk if they snap. When an extension spring breaks, the cable can whip unpredictably.

Both types use a counterbalancing system. Without springs, the opener motor would burn out in weeks trying to lift dead weight. Springs do the real work. Your opener just guides the door up and down.

Signs Your Springs Need Replacement

A snapped spring makes itself obvious. Your door either won't open at all or slams down hard. But early warning signs appear weeks or months before catastrophic failure. Listen for loud banging or creaking sounds. Check whether your door rises unevenly or feels heavier during manual operation. Some doors drift downward slowly when fully open, a sign springs are weakening.

If you've noticed these symptoms in your Lewisville home, don't wait. A snapped spring repair costs less than an injury claim or garage door opener replacement.

Why Springs Fail (And How to Extend Their Life)

Humidity and temperature swings in North Carolina accelerate spring fatigue. The metal fatigues faster when springs cycle through heat and cold stress. Rust also shortens lifespan. If you've noticed rust spots on your springs or rod, corrosion is already eating into the metal.

Lack of maintenance compounds the problem. Springs need lubrication twice yearly to reduce friction and slow wear. A garage door tune-up catches spring issues early, sometimes buying you another year or two of service. For detailed maintenance steps, see our complete garage door maintenance guide for Lewisville homeowners.

Overuse accelerates wear too. Commercial doors or homes with frequent openings see spring life cut short. If your door opens 400+ times weekly, expect springs to fail sooner than the 7 to 9 year average.

Cost and Estimate Reality

I price torsion spring replacement between $250 to $450 per spring, depending on spring size and cable condition. Extension springs typically run $150 to $300 each. These estimates include labor, new springs, and safety hardware. If a cable needs replacement during the job, add $75 to $150.

Cheap estimates should raise red flags. If someone quotes $89 for a spring replacement, they're either cutting corners on safety or planning surprise charges on arrival. Garage Door Lewisville provides free, honest estimates with no pressure. We explain what we find and what it costs before we touch anything.

Many homeowners ask whether to replace one spring or both. If one torsion spring has snapped, the other is near failure. Replacing both at once costs slightly more upfront but prevents a second emergency call in three months. We recommend this approach and explain the reasoning clearly.

When to Call a Professional

Never attempt spring replacement yourself. Torsion springs store enormous energy. A slip, misalignment, or wrong tool choice can cause serious injury. Springs have launched tools through drywall and sent people to the emergency room.

Your garage door is one of the most dangerous moving parts in your home. Springs are the reason it works at all. Treating them with respect and maintaining them regularly keeps your door operating smoothly and safely for years.

Frequently Asked Questions

How do I know if my garage door springs are original? Original springs typically show rust, wear discoloration, or visible fatigue cracks. If your door is over 7 years old and has never had spring service, they're likely original and due for replacement soon.

Can one broken spring keep the door stuck? Yes. A snapped torsion spring removes counterbalance entirely. The door becomes dead weight. The opener cannot lift it, and manual opening is dangerous. Extension spring failure sometimes allows partial operation but creates safety hazards.

Do I need to replace the cable too? Not always. If the cable shows fraying, rust, or visible damage, replacement is necessary. Many jobs replace cables preventively alongside springs since we're already working up there.

How often should springs be lubricated? Twice per year, spring and fall, using garage door lubricant (not WD-40). Proper lubrication can extend spring life by 1 to 2 years and keeps operation smooth and quiet.

What's the difference in cost between torsion and extension spring replacement? Torsion springs are larger and more complex, typically costing 50 to 100 percent more than extension springs. However, torsion systems are safer and last longer, making them better long-term value.
