The Smog Shop

The Smog Shop was established in 2004 to fill the need of a highly trained and friendly smog check station in the concord area. Since then we have done thousands of smog checks and built up a loyal following of happy customers. We are a test only center so we are a completely unbiased when it comes to performing your smog check, which means no failing vehicles to get unnecessary repairs, because we are not allowed to do repairs. We have become Star Certified in the fall of 2012, which means we have been recognized by the state of California as being a top performing smog check station.This certification allows us to perform smog checks on Star Certified directed vehicles.
