Horizon Smog Brentwood

Quick and easy, no appointment necessary, and great price. Found a coupon online, printed it out, walked right in, and 20 minutes later I was on my way. Every other place I called wanted around $30 more for a smog check and wanted me to make an appointment. No thank you, I’ll stick to Horizon Smog!

I needed a smog and called Horizon after a few other places. They had better pricing and availability to do the work so I tried them out. They were super friendly and did the work quickly. I'd use them again and highly recommend them to anyone.

Great experience! The owner/smog tech was professional, friendly and informative. After being a customer at Fire House Smog in Antioch for over a decade I will make Horizon my new go to smog shop.

Awesome! Super fast and friendly.

Brought my car in on Saturday morning without an appointment and they got me in right away and had my smog check done in less than 30 minutes. I was the first one there but they are fast and efficient.

In n out to do my cal .smoggg test. . passed and left did see nice ice skatting rink. Looks like fun for the kids

Been coming here for years! Always friendly staff, quick in and out. Coupon is always a plus

Always amazing! I go here knowing that the service will be outstanding. Anytime I need a smog, or if people I know need to smog their vehicles, I go here and always recommend it to friends and family.

Just dropped in without appointment, Lee was friendly, quick and professional. Had smog cert within 15 minutes. I'll be back next time I need a smog certificate.

Best local certified smog check, imo.

Went to have a smog test done and was in and out within 20 minutes. I would recommend Horizon Smog to anyone who needs test done. Great job! Thank you Horizon Smog.

Great service! Great price! The technician was professional and got me in and out quickly.

They have always been fast and good price.

Great shop! Good price. I fux with them!

Once again I went to them to get my car smog checked. Last time I went was 2 years ago; and as back then, they did a great job! Convenient, appointments not needed and in a normal year, you can walk around town if there is a wait. This year, I was in and out in 15 minutes. Professional, friendly and they always have coupons online.
