7 Signs of a Broken Garage Door Spring (and What to Do)

A broken spring is the single most common reason a garage door stops working, and it almost always happens without warning. The good news: the signs are easy to recognize once you know what to look for, and most spring failures are a same-day fix. Here's how to tell what you're dealing with and what to do about it.

What a garage door spring actually does

Your garage door is heavy, often 150 to 250 pounds. The opener doesn't lift that weight on its own; the springs do. They store tension and counterbalance the door so it glides up smoothly and the opener only has to nudge it. When a spring snaps, that balance disappears and the full weight drops onto the cables, opener, and tracks, which is why so many other parts get damaged when a spring goes.

7 signs your garage door spring is broken

1. 1A loud bang from the garage. A spring releasing its tension sounds like a firecracker or a heavy pipe hitting concrete. Many homeowners hear it from inside the house and find the door dead the next morning.
2. 2The door won't open, or feels twice as heavy. With no spring to counterbalance it, the door is dead weight. A manual lift feels impossible, and the opener strains or won't budge it.
3. 3A visible gap in the spring. Look at the spring above the door (or along the tracks). A two- to three-inch gap in what should be a tight, continuous coil is a dead giveaway.
4. 4The door opens a few inches and stops. Most openers have a force limit and will quit rather than drag a door with no spring assist.
5. 5The door slams or drops crooked. If it does move, it may fall fast or hang lower on one side.
6. 6Loose or slack cables. When a spring breaks, the garage door cables often go slack or come off the drum. Frayed cables are a related failure we check on every visit.
7. 7A bent top section or a straining opener. Forcing a door with a broken spring can bend the top panel or burn out the opener motor, so stop as soon as you suspect it.

Torsion vs. extension springs

Which spring you have changes how the failure looks. Both do the same job in different ways:

What to do (and what not to do)

• Do stop using the door and disconnect the opener so no one triggers it.
• Don't keep hitting the remote, which can burn out the opener motor.
• Don't attempt a DIY replacement. Springs are wound under extreme tension and cause serious injuries every year; it's the repair we're most often called to fix after a DIY attempt.
• Do call for professional broken spring repair, which is usually a same-day job.

Can you open a garage door with a broken spring?

You can sometimes open it manually using the red release cord, but be careful: with no spring the door is full dead weight and can slam down. If your car is trapped inside and you need it out, it's safer to get a tech out fast. After hours, that's what our 24/7 emergency repair line is for.

How fast can it be fixed, and what does it cost?

Most spring calls are same-day because our trucks carry the common torsion and extension springs. In the DMV, a professional spring replacement typically runs about $200 to $500, depending on the spring type and whether you replace one or both. We give a free, exact quote before any work starts. We handle spring repairs across Rockville, Bethesda, and the rest of our Maryland & DC service area.
