Broken Garage Door Spring Repair in Dublin, CA
A broken torsion spring is the most common reason a Dublin garage door suddenly will not open. When the spring lets go, the counterbalance that carries the door's weight is gone, so the door feels impossibly heavy and the opener cannot lift it safely. Valiant Garage Door replaces broken springs across Dublin, usually same day, and rebalances the door before we leave.
Signs your spring is broken
- You heard a loud bang from the garage, often overnight or in cold weather.
- The door will not open, or the opener strains and the door barely lifts.
- You can see a visible gap in the coiled spring above the door.
- The door feels extremely heavy when you try to lift it by hand.
- The door opens a few inches, then stops or slams back down.
Why springs should not be a DIY fix
Torsion springs are wound under high tension and store enough energy to cause serious injury if they release while being handled. Replacing a spring also requires matching the correct wire size, length, and wind to the door's weight, then rebalancing the door so the opener is not overloaded. This is work for a trained technician with the right tools.
What Valiant does on a Dublin spring call
We confirm the door's weight and the correct spring size, replace the broken spring (and recommend replacing both if the second is near end of life), service worn end plates, bearings, and cables as needed, and rebalance the door so it holds position on its own. We test the opener's travel and force before we finish. See real examples on our broken-spring case studies, including nearby San Ramon and Danville jobs.
Fast Diagnosis Checklist
Tell Valiant whether the door is stuck open, stuck closed, heavy, crooked, off-track, noisy, or showing opener error flashes. Photos of the spring line, cable drums, and opener lights help route the call.
