    I can't say enough good things about Eric and his dad -- they are truly the best concrete team I've…read moreever worked with. This is actually my second time hiring them. A couple of years ago they helped me with a smaller concrete project, and I was so impressed by their professionalism and craftsmanship that I knew I would reach out again when it came time to redo my entire backyard. From the very beginning, Eric stood out for his clear communication and honesty. His quote was very fair compared to other contractors I contacted, but what really made a difference was how much thought he put into the design and planning. My backyard was in pretty bad shape -- uneven ground, cracked areas, and even a section near a retaining wall that wasn't very stable. Eric carefully looked at every problem and came up with creative, affordable, and effective solutions. He never tried to upsell or rush decisions. Instead, he made sure I fully understood each option, and he adjusted the plan to fit both my budget and my vision. During the construction, Eric and his dad worked with incredible efficiency and attention to detail. Every single day, they arrived on time, worked hard, and cleaned up so thoroughly before leaving that I could barely tell it was an active construction site. That level of care and respect for a client's home is rare and deeply appreciated. The final result completely transformed my backyard -- the concrete surface is smooth, solid, and beautifully leveled. They even paid attention to the small finishing touches that many contractors might overlook. The project was completed right on schedule, exactly as promised. Eric and his father are honest, reliable, and take great pride in their work. You can tell they truly care about doing the job right, not just getting it done. I wouldn't hesitate for a second to hire them again or recommend them to anyone who needs high-quality concrete work. They're the kind of people you feel lucky to find -- hardworking, trustworthy, and genuinely good at what they do.

    Tran's Landscaping - Materials purchased and the very obvious 90 degree elbows

    I don't want to leave negative reviews because I understand everyone is working hard to make a…read moreliving, but this was the first time I had to stop a contractor after 1.5 days because I was stressed and concerned about the way the work was progressing. I wanted my backyard demoed to install draining and concrete to make it low maintenance and fix draining issues during heavy rains. I felt the materials purchased didn't look right and were also different from what other contractor bids mentioned the material they would use. I even consulted AI and other forums online to make sure my intuition wasn't off. Either way, I don't think these materials purchased were the issue because if I am working with a good contractor, they would be able to either adjust to my request in a respectful manner or explain their approach rather than gaslighting me. First, Tran purchased triple wall HDPE pipes for a very long run for the draining (20+ feet). I assumed we'd be using PVC pipes and that was also the recommendation from most as PVC is more durable and less prone to bellying during the installation process. If issues arise, it's also a better material to snake through rather than triple wall HDPE as it is smoother and more durable. When I asked if the triple wall HDPE pipe could be returned and to use PCV instead, Tran responded as if I were crazy and mentioned the PVC pipe is not for outdoor use. I was taken aback and wasn't sure how to respond to this, I've only seen copper or plastic piping used for my indoor plumbing and there was PVC piping used outside we can see right in front of us as we were talking. Second, it's best not to use 90 degree elbow for my situation, and it's better to use 45 degree elbow to avoid clogging. If you've gone through elementary school, then clearly you can tell the elbow purchased is 90 degrees. I asked Tran if he could use 45, and he responded "These are all 45, you can take this to home depot and check." The elbow clearly looked 90 degrees, so I had to go out to home depot myself, take a picture of the clear difference between the 90 degree elbow he had purchased vs the obvious 45 degree elbow at the store, then he responded, "Ok, let me get the new elbow." This is the second instance of gaslighting that made me feel confused and concerned to trust this contractor to continue work. Third, because the draining was going to be installed underneath concrete, this means it will be challenging to unclog or check for issues if something went wrong in the future. I asked about this and wanted to communicate my desire to install some sort of drain cleanout, but I was cut off and Tran simply stated "I've done this so many times" and never answered my question properly. I felt taken advantage of and disrespected with the gaslighting while working with this contractor. I am spending a lot of money and this is a huge job that needs to be done correctly, as trying to fix plumbing underneath concrete isn't the same as fixing plumbing underneath an indoor sink. The fact that an elbow could not even be purchased properly was the last straw and I did not feel comfortable moving forward. I give 2 stars for showing up each day and working hard to demo the backyard as there was a lot of weeded grass and plants that needed to be removed.

Unfortunately for us, the house had a small concrete patio with most of the backyard covered in cheap mulch. We knew from the day we bought the house that we wanted to remove some of the mulch and add concrete in the backyard. We found Jose's Concrete through Yelp and were impressed with his high rating and pictures of past jobs. We reached out to Jose and he personally came out to hear what we had in mind. Jose was very professional and provided us with a very reasonable quote. He was able to start the work within a couple of weeks which was fantastic news since we were eager to get it done. Jose was personally onsite every day that work was being performed and was super punctual. He listened to all our concerns and ideas and made all the necessary adjustments as the work was completed. My only suggestion for anyone having concrete work performed (by any contractor) is to consider how it impacts your irrigation system. Our landscaper recommended a larger opening around the irrigation system and Jose was able to accommodate and also install a PVC runner under the concrete to ensure our irrigation needs were met. My wife and I are so happy we chose Jose to complete the concrete work in our backyard. This company is an no brainer 5 out of 5 stars!

After reading all the positive reviews, I called Leyva Concrete and spoke with Alfredo. He came out, looked at the space and we talked through the process. I made adjustments to the original scope of work, and Alfredo was super-accommodating. His team finished the excavation work that I started, then prepped for the concrete pour. These guys know exactly what they're doing, taking care with the surface finishing and all the cleanup. True craftsmen. I'm so glad I went with the professionals. They're prompt, the communication is great and quality of work is exceptional. Alfredo and this Team at Leyva Concrete are truly amazing!

Tony gives suggestions and design decisions based off his experience and gives clients insight into potential problems later down the line. This was something other companies did not do and was one of the reasons why we picked him. His team is a one stop shop that can do everything. We had them layout pavers, add drainage and irrigation, and install sprinklers and sod. As far as cost goes, his asking price is mid range, but what sold us was his attention to detail and his excellent communication and responsiveness. He always responds to text or phone and is always reachable. He completed the project right around the estimated time and we couldn't be happier. I think what makes Tony stand out among the rest is that he is present in all phases of the project; from the estimate, the point of sale, the job site project manager, and doing the actual labor. Not having to delegate these roles to others gives Tony keen insight into all facets of the job and allows him to have less overhead which equals a lower cost to the client. I would highly recommend others to have Tony and his team tackle your next home project.
