A broken garage door spring often announces itself with a loud bang, a visible gap in the coil, a door that will not lift, or an opener that strains and stops. Do not try to DIY the repair—springs are under high tension and can cause serious injury. On a two-spring door, replace both springs so the new pair shares the load evenly.
Garage door springs do the heavy lifting. When one fails, the door suddenly feels impossible to raise by hand, and the opener may grind, reverse, or refuse to move the door at all. Dallas homeowners hear that bang most often on a quiet morning or when they hit the remote after weeks of normal use. Knowing the signs—and what not to do—keeps the repair safe and straightforward.
The most common signs of a broken spring
1. A loud bang from the garage
Torsion springs store a lot of energy. When they snap, the sound can resemble a gunshot or a heavy object hitting metal. You may hear it overnight or when nobody is near the door. If you heard a bang and the door will not open normally afterward, treat the spring as failed until a technician confirms otherwise.
2. A visible gap in the coil
Look at the torsion spring (or springs) above the door—usually along a metal shaft. A clean break leaves a gap in the winding. Extension springs along the sides can also separate or hang differently. Do not poke, wind, or “test” the spring with tools.
3. The door will not lift—or feels extremely heavy
With the opener disconnected (only if you know how to pull the release cord safely and the door is fully down), a door with good springs should be manageable by hand. A door that feels like dead weight usually means spring failure. If you are unsure, leave the door closed and call.
4. The opener strains, clicks, or stops
Openers are not designed to lift an unsupported door. When a spring breaks, the motor may hum, the rail may jerk, or the unit may reverse on its safety settings. Forcing more open/close cycles can damage the opener, cables, and drums. Stop using the opener until the spring is fixed.
Why you should not DIY a garage door spring
Springs are under high tension. Improper winding bars, wrong spring size, or a slip during installation can cause severe injury. Cable systems can whip. The door can fall. Online videos make the job look simple; they do not show the hospital visits. Leave spring work to trained technicians with the right tools and parts.

Why replace both springs on a two-spring door
Many residential doors use a matched pair of torsion springs. When one breaks, the other has already done a similar number of cycles. Putting a brand-new spring next to a tired one often means the old spring fails soon after—and you pay for a second trip. Replacing both keeps balance, wear, and cycle life aligned.
Your technician will confirm the spring type (torsion vs extension), wire size, and wind direction so the door lifts evenly and the opener is not fighting a crooked balance.
Typical Dallas spring repair cost (estimate)
From our garage door repair cost page, replacing one spring in the Dallas area typically runs about $150–$350, or about $200–$500 for a pair. These are estimates. Door size, spring type, and related cable or hardware wear affect the final number. Your exact price is confirmed on the phone before work begins.
A warranty is available on the repair—ask for details when you call. We do not advertise a fixed warranty length in marketing copy because coverage depends on the parts and job. Prices shown across the site are estimates confirmed by phone.
What to do while you wait for the technician
- Leave the door down if it is already closed.
- Do not keep hitting the remote or wall button.
- Keep kids and pets away from the door and spring area.
- Note the brand of opener and whether you heard a bang or saw a gap—this helps the phone quote.
- Clear space in the garage so the technician can work safely.
Related problems that look like a spring issue
Broken cables, off-track rollers, and failed openers can mimic spring symptoms. A professional visit sorts that out quickly. If the door is crooked, the cable is slack, or the track is bent, say so when you call so we bring the right hardware.

No. Springs are under high tension and can cause serious injury if handled incorrectly. Use a trained technician with the proper tools and parts.
