Read what a few of our real customers have to say about Diamond Group.
Carlose and his crew at Diamond Group LLC were amazing from start to finish. He answered my call on the first ring, came out the same day for an estimate, and was patient while I chose from countless color options. Our garage floor was stained, cracked, and in rough shape, but in just one day they transformed it into a flawless, show-worthy space. The team was kind, respectful, hardworking, and a pleasure to have around. Their price was very competitive, yet the customer service and quality of work were far above and beyond. Within 72 hours we were walking and driving on the new floor, and I couldn’t find a single imperfection. I highly recommend Diamond Group LLC. If I could give 10 stars, I would. Happy customer. :)
Carlos and his team did a phenomenal job! He explained the process end to end, provided options and communicated well throughout the process. Highly recommended!
The garage floor is beautiful. They did an awesome job and all in one day. We would recommend them to anyone that asks.
From the initial consultation to the final cleanup, everything was handled with professionalism. The new epoxy floor in our workshop is exactly what we wanted—tough, great looking, and slip-resistant. Fantastic job!
We had an old, cracked concrete patio that they turned into a beautiful, functional outdoor area with an epoxy coating. The difference is night and day. We're very pleased with their attention to detail and craftsmanship.
I’m extremely happy with the epoxy floor this company installed in my garage! From the first visit to the final result, everything was done with professionalism, attention to detail, and great communication. The team was punctual, respectful, and clearly knew what they were doing. The floor looks absolutely amazing—smooth, shiny, and super clean. It completely changed the look of my garage and made the space feel brand new. You can tell they use high-quality materials and take pride in their work.
