Smog Check

A smog check is a test done on the exhaust system of a motor vehicle to determine how many pollutants, and of which type, the vehicle is emitting. The smog check also includes an assessment of other parts of the vehicle to make sure that they are in working order, especially those parts which pertain to emissions control.

We service all types of foreign and domestic vehicles and built our business on loyal expert service in Contra Costa County since 1997.
