I recently hired Onyx Concrete Contractors for my driveway project, and I must say they did an outstanding job! The team was professional, punctual, and paid attention to every detail. My driveway looks amazing, and I’ve already received compliments from my neighbors. Highly recommended!

Performed there job on my property with excellence,and expertise and glad I choose onyx to install my new walkway with excellence, thank you

Very professional, on time, high quality. Very highly recommended.

Onyx did a patio job for me. The communication was great and they made the process super easy. I’ve found customer service is not the greatest these days and many people / companies don’t folllow up on their word, pleasantly this was not the case with Onyx. The started the job as planned and finished sooner than originally discussed. The service was great, they worked quickly, throughly cleaned up, and worked carefully not creating any issues or making more work for themselves. They handled all of the paperwork and kept me informed of the status from the onset thru the completion. Highly recommended !!!!!

Recently used ONYX to replace crumbling cement stairs in Oak Lawn area. Once project began, they were quick but thorough. Stairs turned out beautiful! The ONYX team was very professional and easy to work with! Will be using them again if further cement projects needed.

I called so many different concrete companies to repair my walkway. They would come to take measurements then disappear. I found Onyx on instagram. They came in right away and took measurements and started work within 4 days. Onyx did a wonderful job of replacing my concrete walkways and stairs. They were professional and kind. All my neighbors are so impressed at the work they did.

To anyone who's looking for QUALITY concrete, look no further. ONYX Concrete Contractors are the ones for the job! They came out and gave an estimate when they said they would. The price was right & job was OUTSTANDING! Good people to do business with!👌🏽DEFINITELY A FIVE STAR COMPANY!!!💥💥💥💥💥

Concrete work is a big investment and one that you want to make sure that you're hiring the best company to do the work. We found Onyx Concrete through Angi's List and are very glad that they reached out to us. Raul and Angel are the lead guys, and they are great to work with, it's not often that you get to work with a company that knows how to do both the work AND communicate timely and effectively, nonetheless, they do both effortlessly and show great attention to detail, offer suggestions as well as really listen to the customer's needs and/or concerns. Onyx Concrete should be at the top of any prospective customer's list that are looking to have cement work done at their home or business. They are courteous, friendly, super knowledgeable and very professional and their work speaks for itself. It was certainly a pleasure in having the opportunity to work with the Onyx team on my cement jobs. Oh, they did a phenomenal job as well. Onyx, THANK YOU very much! Hillside Resident
