The springs are the muscle of your garage door. They — not the opener — do the actual lifting, counterbalancing a door that can weigh 150 to 400 pounds so it feels almost weightless. When a spring breaks, usually with a bang loud enough to hear inside the house, the door suddenly becomes dead weight. That is why a broken spring is the single most common garage door emergency, and the repair we perform more than any other.

We replace broken torsion and extension springs with springs sized precisely to your door's weight, height and drum setup — never a 'close enough' spring off the shelf. Correct sizing is the difference between a spring that lasts 10,000+ cycles and one that fails again in two years, and between a balanced door and one that eats opener gears.

Signs You Need Broken Spring Replacement

• A loud bang or snap from the garage, then a dead door
• A visible gap of a few inches in the coil above the door (torsion spring)
• Door lifts only a few inches, then the opener strains and stops
• Door feels impossibly heavy when you try the manual release
• Door lifts crooked because one of two springs broke
• Loose or fallen extension springs beside the tracks
• The opener hums but the door doesn't move
• Cables hanging loose or off their drums

Torsion vs. Extension Springs — And Why It Matters

Torsion springs mount on a shaft above the door and wind/unwind to lift. They're the modern standard: smoother, more controllable, and typically longer-lasting. Extension springs stretch along the horizontal tracks on each side; they're common on older and single-car doors, cheaper to buy, but they wear faster and absolutely require safety cables so a failed spring can't fly across the garage.

Your technician identifies your system, then measures the existing spring's wire size, inside diameter and length, plus the door's weight and height. Those numbers — not guesswork — determine the replacement. We also inspect the center bearing, end bearing plates and cables while the system is apart, because replacing a spring on worn bearings wastes the new spring's life.

Why We Recommend Replacing Both Springs

Doors with two springs have two springs of identical age, identical cycles and identical wear. When one breaks, the other is statistically at the end of its life too — often within months. Replacing only the broken one means paying a second service call soon after, and running a door in the meantime whose balance is never quite right.

Replacing the pair in one visit typically costs far less than two separate calls, restores perfect balance, and resets the clock on both springs at once. We'll show you the condition of the surviving spring and give you the choice — but the math almost always favors the pair.

Why Spring Work Is Not a DIY Job

A wound torsion spring holds enough stored energy to break bones or worse if it slips during winding — technicians use proper winding bars, not screwdrivers, and stand to the side of the shaft for a reason. Extension springs under full stretch can snap and whip. Every year, emergency rooms treat thousands of garage door spring injuries, most of them homeowners with good intentions and the wrong tools.

There's also the sizing trap: hardware-store springs are generic, and an undersized spring makes the opener work to death while an oversized one makes the door fly up and slam. Professional replacement costs $120-$350 with the correct spring, proper tension and a balanced, tested door — cheap insurance against a far costlier accident.

Reading Your Spring Quote Like a Technician

A complete spring quote names five things: spring type (torsion or extension), the size being installed (wire gauge, inside diameter, length), whether it's one spring or a matched pair, the cycle rating, and confirmation that balancing and safety testing are included. If any of the five is missing, ask — the answers separate a sized-to-your-door spring from whatever was on the truck.

Cycle rating deserves emphasis because it's the invisible spec: two springs can look identical while one is rated 10,000 cycles and the other 30,000. The price difference is real but modest ($50-$150), and for a household that uses the garage as its front door, it's the difference between repeating this job in six years or in fifteen. Ask for the number; good companies know it offhand.

What Affects Your Price

Three things move a broken spring replacement quote inside the range below: your door's size and weight (a heavy insulated double door needs stronger parts and more labor than a light single), the specification of the replacement parts themselves — standard versus high-cycle or premium grades — and timing, since after-hours emergency visits can add a fee that is always confirmed before dispatch. What should never affect it: how the visit is going. The quote is built from the inspection, named parts and published ranges — for example, single torsion spring replacement sits at $120-$250 while full conversion (extension to torsion) runs $300-$500 — and once you approve it, it is the price.
