about us

Castro Valley's first test only smog check station.

  We are proud to be serving Castro Valley since 2004 back when we were in the 76 gas station on Lake Chabot road. Since 2009 we have moved to our current location at 20747 Lake Chabot road in the old Frank’s Garage building. We do smog checks on most vehicle on a drop in bases, some larger vehicles (motor homes, Box trucks etc.) may need an appointment. So let’s work together to help keep the air cleaner one car at a time.

Every day I try to help my customer like I would my family. So for the old town treatment, give me a call or just drop in. Remember, no question is irrelevant.
