Lim is an excellent technician. Professional, thorough and efficient. Superior service, wouldn't dream of going anywhere else! Thank you!

weird, i left a review on here last year and it's gone! anyway, i love this place, he's super fast and friendly! definitely coming back next march for a smog check! read more

Found Just Smog here on Yelp. Great service, even topped off my tires! Fast, friendly, great value!! I highly recommend Just Smog!!

Recommend this place for your next smog... Quick, efficient and friendly... Great combination

From the time I drove up to the time I left, eleven minutes. It was quick, easy and efficient. The cost for my 2002 SUV came to $50. I hate to have my SUV smogged every other year, but this made it as painless as possible. I'll be back. read more

Fastest and best smog service I have ever had. Courteous help. Would definitely recommend this place. Easy to miss as it is back from the main road on an alley off of West A. Street. The alley is marked by an inflatable air dancer. You've gone too far If you get to the Valero gas station on the corner of Hesperian. read more

I've been here twice and there's always a bunch of cars ready to get their smog checked. Although you think you're going to have to wait when you get there, it's actually super quick! The owner is also really professional, knowledgeable, and friendly. I would highly recommend taking your car here if you don't want to wait for a long time and if you want great service! read more

Everything that everyone has said about this place is absolutely true! The guy who owns and works at this place is honest and friendly. So it was no surprise that there were some cars ahead of me. I asked how long it would take and he said 45 minutes. I didn't really want to wait, but since he had such good reviews I decided to stay. So I went to Starbucks and Target (which are only a few minutes away). When he was almost done with my car, he called my cell phone to let me know. So when I arrived back to his shop, my car had been smogged, I paid the $40 and I was on my way. Great service and great price! read more

Just to tack on to what others were saying, this place is great. Generally quick even without an appointment. Very nice and have even put a waiting area in to sit while they do the work. my 2nd time back. read more

I went to this place for the first time today, and it was a great experience from start to finish. I got there at 9, and the owner (he's the only person who works here, yet he is super fast!) soon arrives and he gives me a friendly wave as I sat in my car. It took less than an hour to wait for the 3 people in front of me and do my smog check. Also, when I called the day before, I was quoted $40 for the check. But after looking at the car (because it was just 2yrs old), he gave me a discount. The owner was also nice enough to spend some time with me to answer all my questions. Very friendly, quick service. You can tell he loves what he does. I would definitely come back here again. If you need a smog check (this is a test-only station), come here. You won't be disappointed! read more

Fast, efficient and friendly service at a low price. A great value. One of the advantages of having a friendly and engaging proprietor is that, If you are inclined, you can get information about your car and possible pitfalls that could affect your smog test results. Since it is a test only site, you don't get answers that are biased toward selling you something else. He works pretty fast, so you won't be there long. But you might as well have an enjoyable experience dealing with someone who is genuinely nice and dedicated to helping his customers. read more

Great experience. I highly recommend this business and its owner to anyone. A super representative of Hayward and its customer-friendly business community. Efficient and competent, with great service and no waiting. read more

If you need quick service with the least wait times, Just Smog is the place to go.

Came back for my Honda, great service and the owner was right there worked on my car right away. Good job Sir!!

Had a wonderful experience here. It cost only $40 and took only about 15 minutes. The guy working there was super nice and friendly. Its easy to find and the service was great. I definitely will be coming back. Happy and now loyal customer. read more

This place is A #1...... I have been taking my cars to a shop where one of my friends work and been paying more and not passing.... Just smog tried to run my truck and would not pass cause of a miss fire. He said maybe it needed a tune up... I asked him how much I owed him he said nothing... I tuned it up and passed with flying colors. read more

Just Smog is the name and that's all that he does. The guy working there seems pretty honest & there's no reason for him not to be since he doesn't do repairs. I've taken several cars there in the past & I don't recall ever paying more than $40 (with certificate). Plus he is fast, courteous, & you don't need an appointment. read more

Lim is great. Honest and friendly and a good price. Knowledge and helpful when problems arise. Highly recommended. He knows good service and knows how to make us loyal customers. Go see Lim! read more

I normally don't write reviews but this place earned it. Great customer service. They complete the job on time and they go above beyond. My car had a gas tank mechanism that was broken and they fixed it without even telling me with no extra charge. Businesses like this that go the extra mile to offer great customer service are far and few these days. Spend your hard earned money with these guys because they truly deserve it. read more

Found this place on yelp. Lim was great! I was in and out of there in 10 minutes. And only 40 bucks not bad. Thanks Lim! :-)

Great service!! I don't know what the guys name wasnor if he owned the spot but he was great! Helped me out a lot. The dude with the 80's Carolla is the man! read more

Got my car smogged here yesterday. I've been going here for a few years. Lim is great! When I pulled my car in, I told him the driver side indoor door handle was broken so he has to open the door from the outside. While he was smogging my car and since he wasn't busy, he decided to remove my door panel and see what the problem was. The cheap plastic handle was cracked in half. Well a couple of drilled holes and four zip ties later I had a working door handle! Lim even told me if I got a new handle he would replace it for me. The handle was too expensive and Lim's "fix" worked so well I didn't bother with the new handle. As long as Lim is there I won't take my vehicle to any other smog station. read more

i did not like the serv ice ,cost much to high, the dog out front scarey

I've used Just Smog three times over the years, and recommended to family members as well. Customer service was excellent and consistent each time I bring my car for smog check. The process was quick and easy. I usually visit on weekday mid-mornings with minimal to no wait time. I highly recommend this place if you are looking for a hassle free smog check experience. read more

Went in today to get my smog check. Great service, quick, friendly! I'd definitely recommend this place to friends!

Took my car in for a smog check a few months back after reading some reviews on Yelp. Brought the car in at 8AM and left 15 mins later. My second visit was just this morning. My G/F needed to get her car smogged so I took her here. Same experience, 15 mins turn around. Owner was friendly and professional. Got the chance to pet Tyson, a very friendly dog. 5 star in my book. read more

Fast, cheap, easy... My review mocks the rest of them, because everything said is true. Go here.

I have read the Yelp and find him, it is so true he is great. Excellent service that why he is so busy we did wait a bit but is worth it. Now on if I need any smog check I will just go to him no other. read more

Great service. I came on Saturday and the shop is almost closed, but the owner can still accept the service. He is very nice. I would recommend this ship to everyone. read more

Great service and FAST! V(smog/owner) great guy and Tyson are top notch.

good price, quick process, small little garage

While I'd disagree with Cynthia and only rate the location 1/3 sketchy, everything else is right on. The owner was friendly and knew his stuff, and the pit bull was a sweetheart once you've been properly introduced. read more

My smog test went very quickly and I was treated very politely and not charged an exhorbitant price. What more can you want?

This place probably does not need another 5 star.. I came to this place only my usual smog man could not hook up my new BMW M Coupe for an out-of-state registration. The owner is super friendly and knowledgeable, took care the smog in less than 15 minutes. He is also a BMW autophile. He gave me some advices on bimmers as well. I recommand him with no reservation. read more

Just got my smog check done. $40 and 10 minutes (he said my car was fast) hahaha. Fastest smog check I've ever experienced. Vea was courtous and professional. I'm definitely a returning customer. read more

super helpful and quick! the doggie was hella cute too, even tho he started barking a few times and creeped me out.

SAN LORENZO SMOG - "Just Smog" is a really great place for San Lorenzo residents to get their smog checks.Yes, I know it is technically in Hayward. It is right next door to the Goodwill, across the street from the Target on A street. It is a test-only station, but don't let that throw you. V charges only $40 and runs around quick to get your car done. He is the first HONEST smog guy I have ever met. It is a drop-in service. He has so much business because, yes, he is THAT good and fair. Bring a book, because he is worth the wait (which is usually around 15-30 mins). Or just chit chat with the locals. Dog Tyson will be happy to greet you and spend time with you. HE IS BUSY BECAUSE HE IS THE BEST. If his line is long, just park next to the building. I have been WAITING to find a smog person I can trust. read more

Stopped in during my lunch break for a re test. He was quick and friendly. I was out in less than 10 minutes. Awesome service.

There's not much I can say that hasn't already been said. There were a couple of cars in front of me, so I waited half an hour instead of the apparenlty usual 15 minutes. $40 is half the price I've paid for smog checks over the past 15 years, the savings made up for the increased cost of my registration. read more

First off I'd like to say that old cars suck....especially here in CA. Took this smog shop 6 attempts over a period of 9-10 months and multiple visits to a repair shop to get my '85 to pass. Not one bit of hesitation from V., the owner, he welcomed me back every time even on the 5th or 6th attempt. Great guy, thanks to him, I'm finally legal again. Of all the times he ran my car on the dyno and all the time he spent....I should have paid him hundreds of dollars, but nope, just charged me what he normally charges for a 15 min smog. read more
