Prof Smog specializes in smog testing and certification in Pinole, California, serving Contra Costa County. Prof Smog is an owner-operated business and the owner is ASE certified. We smog test and certify vehicles whether or not they are required to go to a Smog Test Only Center or a STAR Certified smog station - Prof Smog is Test Only and STAR Certified. We've been in business for 17 years, and our owner has 25 years of experience. We offer smog and emissions tests at competitive prices, and if your vehicle passes, we'll issue your certificate.
We believe in a clean environment and clean air for us and our families. Our objective is to pass the vehicles that should pass and fail the vehicles that should: Quality and Integrity matters here. We believe that in this way we are doing our part in helping the environment as a business and offering our customers the best service we can. When a vehicle fails the smog test, it indicates a potential problem on the vehicle that needs to be addressed. This may help improve vehicle performance or mileage. Also, we believe this may be why we are not just STAR but one of the higher performing STAR stations. Please view the Quality Matters page for more information. Thank You.
Most other smog stations only take customers on a first-come, first-serve basis, possibly creating long lines and wait times. Appointments are available and currently needed so that your service is prompt. On time appointments have priority, but we may take drive-ins if time is available. Contact us at 510-724-9753 (or if email use smog for the subject line) - we usually respond more quickly to telephone messages) today to make an appointment!
