Juan is by far the best detailer I’ve ever worked with. His work ethic and attention to detail are truly exceptional.

I found Juan by googling mobile detailing in my area and have never been so happy with a service! He arrived promptly at 8:30 a.m. and spent most of the day detailing my husband’s and my cars. They both look brand new. Do not bother with anyone else—just call Juan. Also, he is a sweetheart of a man.

Chelsea Ray

I had an outstanding experience with Juan Mobile Detailing! From start to finish, the level of professionalism was top-notch. Juan was punctual, courteous, and clearly takes great pride in his work. What really stood out to me was the reasonable pricing—especially considering the incredible results. Both of my cars looked absolutely amazing once he was done, literally like they just came off the showroom floor. The attention to detail was impressive, from the spotless interiors to the flawless exterior finish. If you’re looking for high-quality detailing at a fair price, I highly recommend Juan Mobile Detailing. I will definitely be using his services again!

Hector Espinoza

WOW! That’s all we could say after Juan finished detailing our Jeep Grand Cherokee. Open the passenger door–WOW! Open the back seat door–WOW!
Open the back hatch–WOW! And all the way around the car. Our “farm” vehicle was transformed into practically new. Thank you, Juan!

Barb Hooper

Shoutout to the BEST Mobile Detailer in Georgia! I just have to take a moment to give Juan his flowers — y’all, he is hands down the BEST mobile detailer I’ve ever come across in Georgia! I had mold inside my car and after Juan worked his magic, the difference was night and day. The results were unbelievable! Way better than it was!!! But wait, it gets better. My tire had been leaking for four months. Everyone else tried to charge me a fortune just to fix it. Juan? He had it patched up and holding strong in 10 minutes. No hassle, no overcharging — just pure skill and integrity. If you need your vehicle detailed, cleaned, or even small handyman work done, call or text Juan asap. He’s truly a FIVE-STAR professional and I promise, you will not be disappointed.

My partner surprised me the morning of my birthday with a full interior and exterior clean of my car in our driveway. I am FLOORED with how amazing it looks! I had a friendly run in with a parking garage gate that left some scuffs on the side of my car – Juan made them DISAPPEAR! It literally looks and smells like a brand new car. Not to mention my partner said he was the nicest person and so easy to work with. HIGHLY recommend for all of your car needs. We will be customers for life!
Lauren Ellisberg

I couldn’t be more pleased with the work Juan did on my car! He arrived when he said he would, he carefully talked me through the options, and helped me choose the service that the car would most benefit from. He used products that worked with my interior, and he got the dash, the floor mats, and the carpets looking the way they looked when I bought the car! And the tires! They gleam! Juan spent 2.5 hours making sure everything was as clean as he could make it, and then he gave me valuable suggestions I can use on my own. He is reliable, patient, and kind. It’s obvious that he wants to deliver exceptional results, and he does! We will definitely be using him again! Thank you, Juan! It was a delight to do business with you!

Robin Langford

Juan is detail oriented, professional, and articulate. He obviously has been doing this for many years and takes pride in his work.
Since he is mobile, it makes your life easier. He has everything he needs in his van including the water. I highly recommend his services!

Laurie Teper

Juan performed exceptional work on my Honda Pilot. As a busy mother of two active and occasionally messy boys, my car required
significant attention. Juan visited our home, and I was impressed by his professionalism and dedication to his job. It’s rare to encounter
individuals who take such pride in their work these days. I wholeheartedly recommend him and plan to enlist his services again in the future.

Yasmin Maisonave

The best mobile detailing I have ever used. Juan’s work is impeccable. He is thorough and professional, and goes the extra mile.

While I have used other mobile detailers, none have matched the results that Juan achieved. And he does his work with a smile!

Nancy Blount

Juan did an amazing job detailing both of our cars. Really attentive to the finest details of the craft and for an excellent price. Cars
looked like when we first took them out of the dealership after he got done with them. It was also great to see how much passion
he puts into his work. He’s a true artist of car detailing.

Jose Rodriguez-Romaguera

I can’t say enough good things about Juan’s Mobile Detailing and their car detailing service! I was in a pinch and needed my car detailed
on short notice, and they came through in flying colors. The professionalism and attention to detail were outstanding. My car looks as good
as the day I drove it off the lot. I highly recommend their services to anyone in need of top-notch car detailing. Thank you for a fantastic job!

Ahnna Barboza

Found Juan when searching for a car detailer. Was impressed by his reviews and I understand why. Juan is an artist and is committed to his profession. Went with his Economic Detail package and the car looks brand new. This is a car that went through kids for 10 years and it looks brand new. 100% recommend Juan and will use his services in the future.
Jason Brenner

I hadn’t driven my car in almost a year and was getting it back on the road, now with an infant in tow. 10 years, thousands of miles, a couple accidents, a busted window, a dog that sheds – it was pretty bad. I wanted to get it detailed but needed somebody mobile. I came across Juan Mobile Detailing and I could not be happier. His website is clear and easy to use including scheduling (being able to quickly schedule online is a huge timesaver); his services and prices are clearly listed; and his communication is above par. He stayed until he was satisfied the job had been done right. He’s clearly passionate about what he does, and, he makes sure you’re happy with the job too. I’ve already recommended him to family and friends and will be using his services in future.
A. Koelling

I agree with virtually everyone that Juan is extremely nice and personable. He also knows what he is doing and is a hard worker.
My car was in desperate need of clay bar treatment, and Juan was exceptional with that and his other detailing services.
He left my half-year old car looking like it just left the showroom. Highest praise for Juan Auto Detailing!

Robert Vance

I chose Juan off Google because of his 5 star rating. I completely agree. He was very thorough, detail oriented,
and focused on my satisfaction. My car has not been this clean inside and out since the day I bought it.

Melissa Rightor

Juan did a superlative job of detailing both my car and my daughter’s, both in the same afternoon. Everything about Juan was professional – he explained what he was going to do and about how long it would take, worked quickly, and did an absolutely gorgeous job on both cars, inside and out. I never thought the inside of my car would ever be that clean again! And he was a delight to work with. I recommend him most enthusiastically.

Excellent work, Juan is super friendly, our car was spotless inside and out. Exceeded my expectations!

Eebs Kobeissi

Juan did an outstanding job. He is a real professional. Arrived early in a well outfitted van, that contained his whole detailing workshop,
including water! He is very friendly and a pleasure to deal with. Juan went well above and beyond my expectations! Thank you Juan, 5 + stars!

John Beerman

Juan is one of the most pleasant and professional people I have ever dealt with in any industry. He is incredibly thorough and performs every service as if he was detailing his own vehicle. If you love your car (or if you want to make it look and feel amazing before you sell it), have Juan detail it! My highest recommendation!
Michael Law

Juan was an absolute life saver! I spilled a half gallon of milk in the back seat of my car on a Monday morning. I called Juan, finding him on Google, and he said he could be there in an hour. Because I had also never had the car detailed, I opted for the full interior detail package and this wonderful man was out in the July heat for 4 hours taking care of the mess of my car. It looks like new!!! The rate was extremely reasonable for how much work this man did (so I of course tipped as well:). Additionally, Juan was SO professional, kind, and polite and had great customer service skills. I 100% recommend Juan for all your car cleaning needs!
Jessica Frega

I heard of Juan through a coworker of mine who used his service. I have had my car detailed before, but this was the best
detail my car has ever had. It looks better than when I bought it brand new. If you want that cartoon shine, contact Juan!!

Charlie Sampson

Our two cars look like new! This is such a fantastic service. Mr. Diaz will come to your home
and provide all the detailing services in 2-3 hours per car. He will definitely be coming back.

Kelly Suttles

Juan worked miracles on my minivan. He came early and stayed late to make sure that the job was done. And the end result was a seven year old van looking brand new. I highly recommend.

Dennis Blanchard

Juan did an incredible job with my car. Not sure what from, but my car had a funky smell to it which is now gone. The interior looks like my car is brand new. On the outside my car is the cleanest I have ever seen it. Juan is also extremely professional and pleasant to work with. I will only be using his services from now on for my car.

Maria Storozheva

Professional, punctual, amazingly detailed, I can’t say enough good things! The car looks like brand new. My husband hired
Juan to detail my car as a Christmas present and I couldn’t be happier. Perfect gift for the hard to buy person on your list!

Sandy Ruben

I am so glad I found Juan! He is incredibly professional, prompt, has clear communication and does beautiful work. He was kind enough to buff out the scratches in my hood that I had written off as permanent. He pays remarkable attention to detail and takes pride in his excellent results. Juan came to my house and literally brought everything he needs in his magic little van including a pressure washer and water tank! He was thoughtful in asking my preference on level of chemical sensitivity. My wife and I were so pleased with Juan’s services that we had him come back and do our 25′ camper trailer the very next week. While I highly recommend Juan’s Mobile Detailing, I hesitate to post this as I’d selfishly like for him to be available for our other vehicles! It is such a pleasure to see our vehicles shining like new after so many salty air, dirty highway beach trips had left their mark on our prized possessions. Thank you, Juan and your lovely scheduling assistant!
Jason McDonald

Juan did a superb job detailing my old car. It looks brand new again, and I am thrilled! He is also very personable and a delight to work with!

My aspirations are to fulfill my customers' visions of their vehicles.
