Wow! Dario, Tessa, and the rest of the team were amazing. From the initial estimate to the completion of our patio, everyone was professional, responsive, and communicative throughout the entire process. I had a lot of questions leading up to the project, and they were always happy to answer every one of them. Dario also made several helpful suggestions during the project and I really appreciated his attention to detail and expertise. The crew cleaned up the job site at the end of each day, which I really appreciated. I couldn’t be happier with our new patio, and I’ll definitely be using HDZ again for future projects. I highly recommend them!

Dario with HDZ did an incredible job on our large patio project! He was a pleasure to work with and he takes pride in your project!

Dario and HDZ Construction were amazing to work with and the quality of the work is the best! Highly recommend!

Despite the fact that there is a minor mishap on the result, I appreciate their overall work. Dario and his team did a neat job with our patio and the steps (I love the steps that Dario made). They gave us the most reasonable quote. We communicated through emails and they were very responsive and patient as we went back and forth with questions for a few months until they started the project.

HDZ Patios and more designed and delivered my french drain project on time and on budget. They were easy to work with, responsive and very neat. I am very pleased with the results and am planning my next project with them.

Dario and his team arrived on time and completed the job with no fuss and transformed my backyard. I will use them again for other projects

In June and July 2023, Mr. Dario Hernandez of HDZ Patios and More completed projects involving: the repair of perimeter fencing as well as repairing some patio issues. In another project, he permanently sealed, against encroaching grass and weeds, the ground where we had dozens of large squares. Thanks to the layering of various materials 'grass and weeds' will never see the light of day on that ground-level patio. I am extremely pleased with Mr. Hernandez's professionalism, work experience and work ethic, and his project outcomes. We look forward to engaging him in additional projects in the near future.MBG, Columbia, MD
