Can I use my garage door with a broken spring?

That is the honest answer. The door might still move a few inches, and the opener might still hum, but every press of the button adds damage. Here is what actually happens, and how to get your car out without making it worse.

Why a garage door with a broken spring is not safe to run

Your door is balanced, not powered. The torsion spring above the opening counterbalances the door's weight so the opener only has to nudge it the last bit. A typical 1/2 horsepower opener is rated to move a balanced door, not to haul the full dead weight.

When the spring breaks, three things go wrong fast:

• The opener takes the full load. The motor and plastic gears strain against 150 pounds or more. They overheat, the gears strip, and a $300 opener can fail on top of the spring.
• The cables jump the drums. With no spring tension holding the door, the lift cables go slack, unwind off their drums, and can whip loose along the sides.
• The door racks out of square. One side lifts, the other drags, and a panel bends or the rollers pop out of the track. A bent panel often cannot be straightened, only replaced.

A door that drops because nothing is holding it up is also a crush hazard for hands, feet, pets, and car hoods. That is the real reason to stop, not just the repair cost.

How to tell the spring is actually broken

Before you decide what to do, confirm it is the spring. Look for these signs:

• A loud bang from the garage earlier, like a firecracker. That is the spring letting go.
• A 2 to 4 inch gap in the coiled spring on the bar above the door.
• The door will not open, or rises a few inches and stops.
• The door feels extremely heavy if you try to lift it by hand.
• The door hangs crooked or slams down when you let go.

If you see a clear gap in the spring or the door suddenly weighs a ton, the spring is the problem. Our guide on the signs of a broken garage door spring walks through each one in more detail.

How to get your car out without wrecking the door

If your car is trapped inside, you have two safer options than forcing the opener.

1. Wait for the tech if you can. Most broken spring jobs along the Front Range are same-day, so a few hours of waiting beats a bent door.
2. Carefully open it by hand, only if needed. Pull the red emergency release cord to disconnect the opener, then lift slowly with a helper. A door with a broken spring is heavy and unpredictable, so keep hands and feet clear and prop it with locking pliers on the track if it will not stay up. Our step by step on opening a garage door manually covers the safe way to do it.

Do not try to wind or replace the spring yourself. A torsion spring stores enough energy to break a wrist or worse, which is why we treat it as a pro only repair.

What waiting too long can cost

A broken spring on its own is a routine, affordable fix. The expense comes from what happens when the door keeps getting used. A burned-out opener, bent panels, and cables that have to be re-run can each add to the bill, turning a single spring replacement into a multi-part repair. Stopping at the first bang, and keeping the opener unplugged until a tech arrives, is what keeps the repair small. It also keeps your home secure, since a door stuck part-way open is an easy target.

When to call a pro

Call as soon as you confirm a broken spring, and unplug the opener so nobody runs it in the meantime. Our techs in Denver, Lakewood, and across the Front Range carry the common torsion spring sizes on the truck, so most repairs are done the same day. We size the new spring to your door's weight, replace it, check the cables and bearings, and rebalance the door so the opener is not fighting it.

If your door is a double with two springs, ask about replacing both. The second spring has the same age and cycle count, so doing the pair now usually saves a second service call within the year. To get a door with a broken spring fixed today, reach our 24/7 line at (303) 937-4477.
