Why Onyx

Concrete isn't just work. It's a craft.

Onyx Concrete is led by Sergio Martinez, who comes from a family of cement masons and spent more than a decade as a commercial foreman before bringing those standards home.

That means level bases, proper forms and steel, and finishes laid with precision. It also means clear communication, honest work, and jobsites the crew would be proud to walk their own kids across.

“He carefully etched the borders, refined the curves, perfected the lines, and adjusted every brushstroke …”William M., front porch extension

Sergio and his team crafted a gorgeous concrete patio with sauna and shower pads for us! I highly recommend them for your concrete projects. Sergio is a knowledgeable craftsman and fantastic communicator, who consistently went above and beyond to ensure we understood our options at each step of the process. His recommendations were spot on and helped us design a space that far exceeded our expectations in appearance and quality. He took extra time on multiple occasions to educate me on the materials and care involved in maintaining the slab and continues to be available for questions on upkeep. His crew was super friendly and professional, leaving us with a spotless yard after huge prep and pour days. Overall, we had a fantastic experience working with Sergio's crew at Onyx!

We had several quotes on our driveway, we chose Onyx because Sergio offered professionalism and the most reasonable price. We were impressed with how fast and efficient they were and their willingness to answer any of our questions on the spot. They arrived every morning at the exact time that was quoted. We were also pleased with how the team took care of surrounding plants, roses, and rockery. The driveway looks fantastic down to every detail. We would absolutely use this company again for concrete projects and would highly recommend them friends and family.

I will forever recommend Onyx for concrete work! Sergio and his team totally saved me last minute. The company I was going to work with flaked, and I had another contractor coming that Saturday to start the framing for my motorcycle garage. I called Onyx on Tuesday. Sergio came out same day to do a bid and spent a considerable amount of time explaining everything to me very transparently. He and his crew were at my house 8am sharp on Thursday morning and got the slab I needed done. Not only was Onyx super quick to help me in this situation, but they did an excellent job. This was just for the foundation of my little garage but they still made sure that it looked nice and was aesthetically pleasing. Sergio was incredibly knowledgable and brings over a decade of experience in commercial concrete work to residential customers. He was professional and transparent, which I greatly appreciated. Concrete work isn’t cheap in general but it is something you probably shouldn’t skimp on. Onyx was reasonably priced for the quality of work they delivered and I’m confident that this foundation was built to last. Thanks again to everyone at Onyx! See y’all on my next project.

Onyx has far surpassed my expectations. I originally considered another option that was the cheaper choice. There was a huge lack of communication and the quality of work was significantly below my standards. My expectations were not met to say the least. I ended up going with Onyx and it was the best decision I could have made. Communication was clear, quality of work was top tier, and the customer service was amazing. Sergio and Jazzlyn have both been great from start to finish. Would absolutely recommend onyx.

I couldn’t be happier with the concrete installation from Onyx Concrete. From start to finish, the entire process was smooth, professional, and well-organized. I had a botched DIY concrete job done the summer prior which did not meet mine or my wife’s standards. Onyx Concrete put my mind at east with a quote that included tearing out the old slab without breaking the bank. The quality of the work truly stands out—the finish is clean, durable, and exactly what I was hoping for. It’s clear they take pride in their craftsmanship, and it shows in the final result. Age old saying of “You get what you paid for!” They also made sure everything was cleaned up and left in great condition when the job was done. If you’re looking for reliable, high-quality concrete work, I highly recommend Onyx Concrete. I’m extremely satisfied with how everything turned out.

Onyx Concrete, did a fantastic concrete patio,walkway, and large concrete pad for a shed and pavilion,in our backyard. Sergio and all his crew were here on time.They were very considerate to our property and our neighbors. I'm very happy with this project. We can't say enough about how professional Onyx Concrete is and how comfortable we feel about hiring them for our front yard ,walkway ,driveway project.
