Garage Door Springs in Dunedin: Torsion vs. Extension (And Why It Matters)
2026-08-12 7 min read A2Z Garage Doors
Most people don't think about their garage door until the springs snap. You press the remote, hear a loud bang, and suddenly your door won't budge. The truth is, garage door springs in Dunedin fail predictably, and knowing which type you have can save you money and headaches when replacement time comes.
What Are Garage Door Springs?
Springs carry the weight of your garage door. They're engineered to balance a door that typically weighs 300 to 400 pounds, making it easy to open and close. Without them, you couldn't lift your door by hand. Springs last 7 to 9 years under normal use. When they're done, replacement is the only safe option.
Two main types exist: torsion springs and extension springs. Both do the same job but work differently. Torsion springs twist around a rod above your door opening. Extension springs stretch horizontally along the top of your door frame on either side. Your garage door likely has one type or the other, sometimes both.
Torsion Springs: The Standard Choice
Torsion springs are industry standard for residential doors in Dunedin and across Florida. They're mounted above the door frame and rotate to lift the weight. Most modern garage doors use this design because it's safer, more balanced, and lasts longer.
When a torsion spring snaps, you'll hear it from inside your house. It's unmistakable. A snapped spring means your door won't open unless you have a backup battery opener. The spring can't support the door's weight anymore.
One big advantage of torsion springs: they fail visibly. You'll see the break or hear the pop. Extension springs, by contrast, sometimes fail without warning because they're enclosed in safety cables.
Extension Springs: Older and Less Safe
Extension springs stretch to lift the door. They're typically found on older garage doors or lighter residential doors. They extend and retract as the door moves up and down, pulling on cable systems at the bottom corners of your door.
Extension springs still work, but they're riskier. If a spring snaps, the safety cable might catch it, but that cable can also snap under pressure. A spring whipping loose can damage your door or injure someone nearby. Most modern installations favor torsion springs for this reason.

Why Springs Fail in Florida
Our climate in Dunedin puts extra wear on springs. Salt air from the Gulf, humidity, and temperature swings all affect spring lifespan. Saltwater corrosion weakens metal faster than in drier climates. Springs that might last 10 years elsewhere often last 7 to 8 years here. If you live near the water, inspect your springs annually.
Heat also matters. Your garage can reach 120+ degrees on summer days. Metal expands and contracts, and springs fatigue faster under that stress. Lack of lubrication speeds decline too. Many homeowners never oil their springs, which accelerates rust and wear.
Cost and Honest Pricing
A single torsion spring replacement typically runs $150 to $300 in labor plus the spring itself. Extension springs cost slightly less per spring but usually come in pairs, so budget similarly. Most residential doors need two springs replaced at the same time, even if only one broke.
Why replace both? Springs wear together. If one failed, the other is probably near the end too. Replacing just one leaves you vulnerable to another failure weeks later. That means another service call, more downtime, and a second emergency fee. We always recommend replacing both to save time and money long-term.
Some shops will quote you $500 to $800 per spring just because they can. That's not honest pricing. We price spring replacement fairly because we want customers for life, not just one job. When you call us for an estimate, we'll tell you what you actually need and what it'll cost.
When to Call a Professional
Never attempt spring replacement yourself. Springs carry tremendous tension. A snapped spring under load can cause serious injury. Professional technicians use specialized winding bars and safety equipment. We've been trained to handle this safely.
If your door won't open and you suspect a snapped spring, don't force it. Call for help. If you have questions about whether your springs are the problem, our garage door safety inspection service can diagnose issues accurately.

Frequently Asked Questions
How do I know if my garage door spring is broken? Your door won't open or opens very slowly, or you hear a loud metallic snap or bang. The door may hang unevenly. Never try to open a door with a broken spring, as the opener will strain and potentially break as well.
Can I replace just one spring? Technically yes, but we advise against it. Springs wear at the same rate. If one failed, the other is likely near failure too. Replacing both now prevents another emergency service call in weeks.
How long do garage door springs last? In Dunedin's climate, expect 7 to 9 years of normal use. Salt air and heat accelerate wear. Professional lubrication and annual inspection extend lifespan slightly.
What's the difference in cost between torsion and extension springs? Torsion springs cost roughly $150 to $300 per spring plus labor. Extension springs are slightly cheaper per unit but rarely come alone. Total labor and parts are comparable between both types.
Should I replace springs if my door still works? If springs show visible rust, have frayed cables, or are more than 8 years old, yes. A preventive replacement costs less than an emergency call. Worn springs also stress your opener, potentially causing expensive damage.
