San Ramon Garage Door Repair: Broken Spring & Worn End Plate
A San Ramon homeowner woke up to a garage door that would not lift. A torsion spring had snapped overnight, and the spring assembly's end plate was worn. We replaced the spring, serviced the end plate, and rebalanced the door so it was safe to run again.
What the homeowner noticed
The door would not open. The opener motor ran and strained, but the door barely lifted off the floor. The homeowner had heard a loud bang from the garage the night before, which is the classic sign of a torsion spring failing.
What we found
The torsion spring above the door had snapped, so the counterbalance that normally carries the door's weight was gone and the opener was trying to lift the full weight on its own. The end plate, the bracket that holds the spring assembly and bearing at the end of the shaft, was also worn and needed to be serviced.
The repair we recommended
We replaced the broken torsion spring with the correct size for the door's weight, serviced the worn end plate and bearing, and rebalanced the door so it holds position on its own. We then cycled the door several times and confirmed the opener was no longer straining.
Before and after
How the door worked afterward
With a new spring and serviced end plate, the door lifts smoothly and holds at every position, and the opener runs without straining. If your San Ramon door will not open, feels extremely heavy, or you heard a bang from the garage, call (925) 409-4974 or book your repair online.
