This review is long overdue due to my procrastination. I used Monarch Concrete for repaving the…read moreconcrete slab in my garage in 2024. Eric was very responsive to many questions that I had in emails. His price was very reasonable. He and his dad are very knowledgeable in their trade. They are a great team. My garage is slightly sloping towards the center of the house. There is a drain near the garage door. His dad made the ditch to channel the rain water to the drain. Ever since that was made, the rain water was channeled well and there is no issue of water gushing into the garage during heavy rainstorms. Rest assured if you have Monarch Concrete do your work. It will be the best workmanship and outcome for your work.

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.

I would have given ZERO stars. Don't trust their overall YELP rating. I made that mistake. I feel…read morethe finished work (driveway, pathways, and wall) are reasonably acceptable. This is ONLY because we checked daily work and instructed them to fix mistakes and sloppy work. They spent a lot of their time redoing what should have been completed right the first time. Daily progress (or lack there of) showed us that the owner/project manager (Tevita/Mata) is not a good project manager nor that he gave his crew clear direction on this project. The process after contract signing was horrible...not at all professional. The project took much longer than Tevita initially quoted (over 2 months vs the 2 weeks he originally told us). This resulted in change orders and cost overruns. He also tried to charge me to fix their breakage/mistakes/errors (e.g., fixing the sidewalk his workers broke). His crew was not respectful of our property (we had to live with their mess...it's not a vacant lot). They did not regularly clean up the work site nor organize equipment and materials left onsite. Seeing their lunch garbage (cans, bottles, wrappers, etc.) at the end of their workday was common. This continued even after repeated complaints to Tevita and to his crew. No one on site could to provide straight answers as to that day's work or when specific project goals would be completed. Whenever I would spoke with him, Tevita made excuses, provided misinformation, denied deliverables he previously promised, and deflected from answering direct questions. He has a habit of talking over the customer when asked questions he doesn't like. On at least one occasion, he raised his voice and started yelling to avoid answering questions. If it was not in writing, he'd say it wasn't what we discussed. I have never had such issues when working with professional/reputable companies. Tevita and his crew failed to meet every single deliverable date he set. I found him very difficult to work with. I feel that he does not show proper respect to the customer. Instead he appears to think that the customer, the person paying him, should accept subpar work. I suspect that he may also not fully understand the processes involved with the work being performed. I feel that Tevita and Lamata Concrete are not professional. They didn't use professional equipment and they didn't manage the job site or their onsite work time professionally. Their workers typically started late morning and were gone by early afternoon. Lamata Concrete has major logistical problems. They couldn't get an adequately-sized crew or required materials to the job site at the start of any given day, typically interrupting workflow for hours to go fetch supplies. Had they staged materials and tools at the worksite (where there was ample area to store all materials needed for the entire project) and had his crew worked a full 8 hours per day at the job site, I believe they could have finished weeks ago. They are SLOW...3 weeks for a stamped concrete driveway and pathways. I definitely CANNOT recommend them for a cinder block wall. It took way too long (over 2 months) to complete. I feel like they have never built this type of wall. I regret hiring Lamata Concrete. I CANNOT recommend Lamata Concrete nor would I use them again. They were such a hassle to work with compared to the many other professional/reputable companies I have hired. My opinion...take their negative YELP reviews seriously and ask for references and talk to those references. Tevita's response is a great example of how he makes excuses, provides misinformation, denies promised deliverables, and deflects from addressing the real issue. I find it a bit childish and very unprofessional.

Steve was able to work through a some extra issues/work we uncovered and communicated to us through the delivery delays that were outside his control.

Long story short we called Steve to come and help us. He stuck to the same quote that was originally quoted and finished in 3 days. He uses high quality cement, rebar, and most importantly he communicates. Don't cheap out Just get it done correctly with Concrete Warriors!

Just like our first project, Alvaro and his team were super professional and did an excellent job. I cannot emphasize enough how appreciative I am of how communicative and punctual Alvaro was throughout the whole process, which made the entire experience completely stress-free. Alvaro provided quote updates within 24 hours and quickly answered all of our questions. The team arrived on time every single day, which was especially impressive as they worked through the hottest week of the year so far. The project went incredibly smoothly. Alvaro gave us daily updates every afternoon on what they accomplished and what they were going to do the next day. They also kept the job site very tidy and left everything spotless when they were done. We are so happy to have worked with Alvaro and his team again, and they will definitely be our go-to for any future concrete projects. Highly recommend Sandoval Concrete for anyone looking for high-quality work!

I didn't appreciate the message, as well as the lateness of the notice. I suppose it's better than a no show. If their criteria was to not work certain areas and neighborhoods, an appointment never should have been made.

Vanessa specifically provided excellent, white-glove service throughout the entirety of the project and was super responsive to all of our communication. We did have a number of issues arise with the crew (mainly excessive dust seeping into our house and trash being left behind on the neighbor's property line), as well as the accounting department (an accidental attempt at overcharging us), but Vanessa always did an excellent job of troubleshooting these issues and helping to guide everybody towards a resolution. She also worked diligently on our backyard design and expertly guided us through several iterations and unexpected construction issues. I highly recommend working with Vanessa and Black Diamond Pavers.

We selected Rangel Concrete to build a new retaining wall and steps in our backyard. We reviewed…read moremultiple contractors, arranged site visits, and received 4 bids.  When we got the bid and schedule from Rangel, they were our first choice. We are happy to report that Rangel was the right choice.  We needed to replace a cracking, root-ravaged cinder-block 30+ feet long, 5' 3" tall retaining wall and steps leading up to our terraced backyard. We had engineered plans for a cast concrete wall.  We need a contractor interested in working with the plans and the city. Our meeting with Rangel gave us confidence that they understood the project and would be pleasant to work with. They provided a very competitive bid and were available to start the project in time to ensure that it was completed by the end of summer. Some contractors would not commit to a timeframe or estimated that it would take more time to complete than seemed reasonable.  Francisco and his crew began work at 7:00 each morning and worked hard the entire day with just one much needed lunch break. Rangel had all the necessary equipment for this sizable project. They removed the old wall and dirt, dug a new trench, installed rebar, stirrups, ties, drain rock, waterproof membrane, built forms for the new cast concrete wall, etc. The site was kept as clean as possible.  Francisco was very pleasant to work with. He persistent and creative in bringing the plans to life with forms and rebar. He made useful suggestions, was very communicative, and was clearly committed to the outcome. Maria kept us up to date, communicated well with the city inspector, and was delightful to work with. We recommend Rangel Concrete highly.
