The median house in Brentwood went up around 2003, which puts a lot of garages here at an age where the opener has never been swapped - just the same motor head that came with the build. That generation ran chain drive almost across the board, with a logic board and a fixed-code remote instead of the rolling-code systems that came later. We carry the parts that fail on units of that age: drive gears, start capacitors, sensor eyes, and the wall control stations that crack after two decades of use.
One honest limitation: a handful of circuit boards from that specific era were discontinued by the manufacturers years ago. When we can't source the exact board, the fix isn't a patch - it's a new head unit mounted on your existing track and rail, which usually run fine long past the motor's life. We'll tell you straight which repair is worth doing and which one is just delaying a replacement you'll pay for twice.
