Jonathan and his crew did a great job replacing old asphalt with cement on our private street. It was a large area, a 4 truck pour. The coordination of all the details and timing was perfect, and he kept us well informed on through out the process. A professional job by a true professional. If you want it done right, Have JNS do it. read more

Wow ... What an incredible company. I am so grateful to Jonathon and JNS Concrete for his professionalism, skill and kindness. You don't need to look any further. This company stands miles above the rest!! Thank you!! read more

I wanted to refurbish a stone pathway in my backyard but after considering the amount of concrete I'd have to mix and pour plus strain on my back and body I opted to get this done by a professional. JNS was very responsive to my initial phone call, quick to come out and have a looksee at my project, made suggestions that saved us time and money plus his pricing was fair. Oh, and did I say he batted this project out in just five hours? He and his crew did a beautiful job. read more

JNS Concrete replaced driveways for two of my neighbors that had the same problem with their old driveway as I did. The texture coat was flaking off and it looked awful. The work JNS did for my neighbors was top notch so I called JNS owner Jonathan and he gave me a reasonable quote and I gave him the go-ahead. They demoed the old driveway on Monday, finished removing the rubble and laid down the re-bar on Tuesday and poured and finished the concrete on Wednesday and it's perfect. JNS Concrete is a great company to work with! We are very happy with our new driveway. read more

JNS did a first rate job on our driveway extension/broadening. Joel is a solid and honest person. They were on time, professional and worked their butts off to get the job done before the rains came. This is a quality company. I highly recommend them. read more

We could not be more thrilled with the job that JNS did at our home in Costa Mesa. We replaced the driveway, pathways and the garage floor. Lots of unforeseen problems along the way coupled with more rain than we ever thought possible and Jonathan was fantastic throughout - lots of communication and totally rolled with the punches as the job progressed - he is a great problem solver. The finished result is WONDERFUL and has given our house new and improved curb appeal. It was a big job and we felt that we got great value hiring JNS. Call Jonathan with no hesitation - you won't be disappointed. read more

Had our driveway replaced and improved upon. Many obstacles were dealt with skill and good judgement. Highly recommended.

What can I say, SO happy with the end result. Jonathan and his crew were a pleasure to work with. They went above and beyond to make our vision come to life and help make our house a home. From the first day Jonathan came to bid the job to the last day, our experience was great. The attention to detail and skill level is second to none. Look no further for your masonry needs, and as long as Jonathan is around I won't need another bid. Happy Lifetime customer here. See photos before and after. No further explaination needed. read more

Excellent quality of work done on my patio with great attention to detail from start to finish. It was such as pleasure doing business with Jonathan. He's a man of integrity, super efficient, and straightforward. I 100% recommend JNS concrete. read more

This is a long-delayed review for a fairly large scale residential project Jon and his crew did some time ago: We hired Jon and his crew to re-do an entire backyard and side yard project. Unfortunately, prior to Jon, we hired a guy who ultimately could not complete the project. Jon and his crew not only was one of the few willing to take on the project, but he offered extremely fair pricing. The scope of the project involved grading and leveling our backyard for additional space and erecting a new retaining wall and planter boxes. Jon and his crew did a great job, especially with the retaining wall. The engineer over-engineered the wall by our request, but Jon did not blink or complain about the added time/energy needed to build a great retaining Wall. Jon and his crew did not cut any corners in the execution of this project, and it shows. Even now months later, the wall has not deflected or cracked. The members of Jon's crew are equally as upstanding as Jon himself. The patience they demonstrated with our amateur designs and questions is matched only by their professionalism. And unfortunately, our lack of experience definitely pushed Jon himself. Sorry Jon, and thanks for being patience. We really appreciate it. TLDR; Jon and his crew are definitely professionals to their toes. But it's a great idea to know what you want ahead of time and stick to it for everyone sake. Thanks again Jon! read more

We recently discovered that the cement block wall we share with our neighbor was cracked and tilting significantly due to a giant bird of paradise. Jonathan gave us a reasonable quote and was able to start the job quickly. His team was very easy to work with, did quality work, and cleaned up the site when they were done. I would highly recommend working with JNS Concrete! read more

Was interested in getting a bid but simply couldn't get a reply. He blames lousy cell service. Oh well on to the next.

The whole team did an amazing job on my front and backyard. They gave me a reasonable price and Jonathan's customer service was impeccable. My house definitely stands out on the block and I've had so many neighbors compliment me already. Great job! read more

Jonathan and his crew did an awesome job on our project. Our project consisted of 235 linear ft 6 ft tall block wall. Prior to choosing JNS, I obtained nearly 10 quotes from other contractors. JNS was the most reasonable and knew all of the requirements for our city, which really set me at ease and that's why we chose them for our project. The team was very knowledgeable and hard-working​. They did a great job through all the weather obstacles and ensured that our residence was always protected during the duration of our project. I've had neighbors come by and ask me who our contractor was because they did such a great job. I would recommend them to anyone and plan to use them again for future projects. read more

After damage to our block wall I asked for estimates from a few vendors. JNS Concrete's owner Jonathan responded in a very timely manner not only with an estimate but in person to answer my questions. His guys showed up on time for the scheduled work and were very courteous and professional. We are quite happy with the workmanship and the cleanup upon completion. read more

Beautiful job, reliable, clean, and friendly. Already recommended to neighbors who were impressed with the work at our house. Great crew too! read more

I wish every business could be like this. Called Jonathan, he came the next day to give an estimate, which was very reasonable. He and his crew took 1 week to remove and replace the slab in my garage and the driveway. Totally easy and smooth from start to finish. I'd recommend him to anyone. read more

The worst. Jonathan is very difficult to talk to. He is a screamer, and a control freak who thinks he knows everything. He was asked to join a board get together to discuss structural changes. He literally screamed behind his mask that his time is precious and he had to leave. He had already completed a lot of work for our complex and was paid $$$. .He insulted me for being disabled. "You can't satisfy her." Chucking like a complete fool. I saw his work,it's okay, it's just cement. I got the feeling his educational level is up for grabs. Understand I have never met this loud mouth before and he's sizing me up and laughing that I don't know anything about concrete. Uh duh. That's why he was supposed to be there as a consultant. I was trying to explain that a sidewalk needed to be extended. That's it. He didn't seem to understand. He told me they can re asphalt and if I want a sidewalk then I should paint the asphalt white myself. It was a disabled slam. It was obvious I couldn't paint it and was a pretty cheap shot. He knew I was talking about concrete. Maybe he can lay cement, not a high threshold to meet, but you have to deal with HIM. Pass and run away as fast as you can. Really unpleasant man. read more

Great is not the half of it! I have seen cement work and beautiful cement work. JNS does, without a doubt, BEAUTIFUL work! #1 Jonathan worked out the design and price details over the phone, with the out of area property owner. He kept us both on the same page without the need to contact him for an update. I prefer contact by text including photos. He sent photos to the owner and to me. I saw the rebar in place and the finished driveway. Beautiful is the word for JNS's work. The owner decided, after the driveway was compete, to call JNS and order a huge cement back patio. Property is now ready to rent. read more

Jonathan's professionalism is impeccable! He guided me in making the right design/color choices for my driveway & walkways. The results are beautiful and I couldn't be happier. He & the crew are highly skilled, hard-working and extremely polite. Kudos to Team Jonathan! Tina & Robert, Murrieta read more

They are very professional and they always do excelkent work. Jonathan was very helpful with our project always shows up everyday with his crew and they did a wonderful job with our concrete. Highly recommend. read more

JNS removed our garage floor, as it had been cracked for many years due to tree roots. The broke up the concrete, removed the invading roots, leveled the ground, placed a barrier down. Then they put in rebar, tied it all together and poured the concrete. What a difference! I highly recommend Jonathan and crew. read more

Jonathan and his crew were very professional, on time, and did a top notch job. His prices are extremely competitive and his work is top of the line. They did my back patio and front walkway and I will definitely use them in the future. Jonathan was very patient with explaining everything and did exactly what he promised. I highly recommend him and his crew. read more

I really, really wanted to give JNS Concrete 5 stars because Jonathan communicated well, was reliable, competitively priced, was on site to keep an eye on the job, and is an all around great guy. Jonathan and his team are knowledgeable, friendly, and work hard to get the job done. My property was built in 1958, added on to twice, and the previous owner was a DIYer. Needless to say, surprises lurked in the shadows. There were two small areas drainage went toward the house instead of away. The deduction of one star is because we still had issues with drainage in those same areas after the new concrete was installed. Jonathan immediately acknowledged both issues and corrected them as quickly as possible. Drainage is working better than ever now. Since big home improvement/repair projects rarely go smoothly or come out perfect, I recommend Jonathan and JNS Concrete for your next concrete project both because the work they do is high quality and if there's an issue Jonathan will make it right. read more

Jonathan came out to give us a quote for a new concrete patio back on July 2, and we were very pleased with that meeting, he is very knowledgeable and professional, he notified me that he would be a little late to the appointment, whereas two other contractors that we had appointments set up with didn't bother to show up or even call to let us know that they wouldn't be showing up. He was also very patient with us due to the fact that our backyard is turf and the turf company had to come out to pull back the turf from the old patio, this took over a month to be completed. Once our job date was scheduled, he and his team showed up on time everyday, explained what they would be doing each day until the job was completed. His crew very polite and at the end of the day, they never left a mess behind. Our experience with JNS Concrete was one of the best contractor experiences we have ever had!! Thank you Jonathan, James and the rest of the crew for our awesome new patio. You Guys ROCK!! read more

Jonathan and James did a block wall for me 3 years ago and last week I asked them to do a repair on a different block wall. Three years ago they did such a good job and followed the recommended city permit instructions which must have been a pain as the footing had to be much larger then anticipated because I live in an area that has sandy soil. They did not up their estimate even though they had to mix way more concrete. So I called them back and they actually worked with my tight schedule and got it done promptly and professionally. A humble pair with nice personalities. Reasonably priced read more

Jonathan and crew did a wonderful job repairing and extending our driveway. The workers were professional, showed up when they said they would and the driveway was completed in a timely manner. We are very pleased. read more

Jonathon and James did a really nice patio for our shop. Our employees are really enjoying their new break area. Work was beautiful and professionally done. We put a few changes in thru the process and Jonathon was very receptive to anything that made the project better. These guys are hard working honest guys. We wish them all the best.

I am really grateful that when I searched on-line for block walls JNS Concrete came up as one of the entries. My new block wall is wonderful! Jonathan, James, and crew are truly professionals. The price was reasonable. They were easy to talk with. They care about what they are doing. Also, Jonathan even took his time to meet me at City Hall to help me obtain the permit. I definitely endorse JNS Concrete. P.S. Other workers that I have hired I wouldn't recommend, including the mason who rebuilt my 1951 chimney which toppled over during the La Habra earthquake.

Jonathan and James built me a patio as well as planters lined with colored bricks and stucco for my backyard. It turned out beautiful. Throughout the process, Jonathan answered my questions and listened to my concerns. He shared his experience and knowledge from previous jobs and we worked together to design my space. We also needed some electrical work done for our fountain and they were able to find someone who could come do the job. He was reasonably priced (verified through another quote), showed up on time to do the work, and completed the work as scheduled. Whereas other contractors will work multiple jobs at once and leave my space half done for days on end, his team came every day until the job was done. I will definitely keep him in mind when/if I need additional work done with concrete! read more
