What to Do When a Garage Door Spring Breaks

How you know it was the spring

A breaking torsion spring is loud — most people describe a gunshot or a heavy shelf collapsing in the garage, often at night or early morning when cooled metal is contracted. Afterward the signs are consistent: the opener strains, lifts the door a few inches, and quits; the door is unliftable by hand; and if you look at the shaft above the door, one spring shows a clean gap in its coils where it separated.

If the bang was followed by a crooked door or a cable hanging down, the snapping spring likely whipped the cables off their drums too — common, and part of the same repair visit.

Do these five things

• Stop using the door entirely — no more opener attempts. The opener isn't built to hoist an unsprung door and will strip its drive gear trying.
• Leave the red emergency release cord alone while the door is up. Pulling it disconnects the opener — the only thing still holding the door — and the door can fall fast.
• Keep children, pets, and (if possible) vehicles away from and out from under the door.
• Look, don't touch: from a safe distance, note whether the spring gap is visible and whether cables are loose. That description helps any technician arrive prepared.
• Call a garage door company. In Las Vegas, GRC Garage Doors answers at 702-758-4397 — tell us if a car is trapped inside and we'll prioritize accordingly.

If your car is trapped in the garage

This is the most common panic scenario, and the honest advice is unheroic: a same-visit spring replacement is almost always faster and safer than improvising the door open. Manually lifting a door with a broken spring means dead-lifting 150–300+ pounds with nothing to hold it up. If work or a flight genuinely can't wait, say so when you call — a trapped vehicle moves you up any reasonable company's schedule.

Why you shouldn't replace a spring yourself

Torsion springs are wound under enough tension to lift the heaviest moving object in your house, and they release that energy instantly if a winding bar slips or a set screw lets go. Emergency-room case reports on DIY spring work make grim reading — hand, face, and head injuries dominate. The job also requires matching spring wire gauge, diameter, and length to the door's exact weight; a mis-sized spring leaves the door unbalanced and grinds down the opener.

This isn't gatekeeping for business reasons — plenty of garage door maintenance is safely DIY (lubrication, sensor cleaning, safety tests). Spring work just isn't on that list.

What the repair involves and what drives the price

A proper spring replacement: confirm the failure, select springs matched to the door's weight, wind them to specification, re-seat any thrown cables, balance the door (it should hold steady at mid-height), then reset the opener's force limits and run both safety tests. On two-spring doors, expect an honest recommendation to replace the pair — the surviving spring has identical mileage and mismatched springs balance the door unevenly.

Price moves with spring size (set by door weight), one spring versus the pair, standard versus high-cycle rating, and any collateral damage. A trustworthy company gives you the full number before touching a wrench. For Las Vegas service, see our garage door spring repair page or call 702-758-4397.
