A customer called last Tuesday morning. Her garage door wouldn't budge, and she heard a loud bang the night before. A torsion spring had snapped. Within two hours, we had her door working again. If your garage door spring breaks, the door is essentially locked in place. The good news: repair is straightforward, costs are predictable, and we offer same-day service across Renton.
Garage door springs carry enormous tension. A single torsion spring can hold 200 to 400 pounds of force. When one fails, the entire weight of the door (typically 300 to 500 pounds) falls onto the garage door opener motor and cable system. The motor cannot lift a door without spring support. That's why the door stops moving immediately. See our guide on 10 essential garage door maintenance tips every homeowner should know.
You'll usually hear a loud crack or pop when a spring breaks. Sometimes the door is half-open. Sometimes it's fully closed. Either way, don't force it up manually. Forcing a door with a broken spring can damage the opener, the cable, or even injure you.
Extension springs (those coiled springs on the sides) can also snap. They're less common in newer homes but still present in many Renton installations. The failure pattern is similar: sudden noise, door won't move, and immediate need for repair. Read about garage door repair in renton: troubleshooting common problems before you call.
Garage door springs last 7 to 9 years under normal use. That's roughly 10,000 to 15,000 open/close cycles. In the Pacific Northwest, moisture and temperature swings accelerate wear. Cold winters and damp springs stress the metal. If your door opens and closes multiple times daily, springs wear faster.
Regular maintenance extends spring life. Lubrication reduces friction. Inspection catches early signs of wear before a full snap occurs. We recommend checking springs every 12 months, especially if your door is over 5 years old.
One spring typically fails first in a two-spring system. When that happens, the second spring is usually close behind. Many homeowners choose to replace both springs at once, even if only one has snapped. That decision saves money on labor and prevents a second emergency call weeks later.

A single torsion spring replacement typically runs $200 to $350 in labor and parts. An extension spring costs $150 to $250. Prices depend on spring type, door weight, and whether we're replacing one or both springs.

If your door also needs a new cable or the opener needs adjustment after spring failure, costs increase. That's rare but possible if the broken spring damaged other components. Before we start work, we give you a free estimate with no surprises. You'll know the total cost upfront.

How do I know if my garage door spring is broken? Your door won't open or close, and you'll likely hear a loud popping sound when it breaks. The door may hang unevenly or feel much heavier than normal. If the opener motor is running but the door doesn't move, suspect a broken spring.
Can I open my garage door manually if the spring is broken? Technically yes, but it's difficult and risky. The door weighs 300 to 500 pounds without spring support. You could strain yourself or drop the door. It's safer to call a professional for repair.
Is spring repair covered by homeowner's insurance? Usually no. Homeowner's insurance covers sudden damage from weather or theft, not wear and tear. Spring failure is considered normal wear. Check your policy, but expect to pay out of pocket.
How long does spring replacement take? A straightforward replacement takes 45 minutes to an hour. If we need to adjust the opener or inspect other components, add 15 to 30 minutes. We'll give you a time estimate when you call.
Should I replace both springs if only one is broken? We recommend it. Both springs wear at similar rates. Replacing both prevents a second failure weeks later and saves labor costs in the long run.
