Kudos to "Papa Memo"- who has been a masonry contractor for over 40 years, he made sure the planter wall was leveled and sloped perfectly. So joyful to hear him singing while working that I asked him to sing my late father's favorite Mexican songs. Hope people whose reading this will enjoy Papá Memo's singing too :-) We express our profound gratitude and look forward to working with Guillermo in future projects.

Being a first time homeowner is not easy. From landing the house and finding things to improve over…read moretime, my wife and I knew the backyard would be a very important space for our family, especially our younger kids. When we first moved in, the backyard was all cement, the grass was dead, it had mulch/tanbark everywhere, and the pavers were mismatched. While we had a temporary "fix" by removing the grass and installing turf, we knew we needed to go big. I went through countless hours of research, hesitation, and uncertainty for whatever reason, but I finally settled on a name that, after extensive research, felt like they would be the right fit for us. Enter Black Diamond! Stephanie Driscoll was our project manager and designer and Raul was the head of the crew that took on the job of totally revamping the entire backyard and the side yards. Stephanie was very easy to work with and loved the design that was initially proposed. Instead of trying to essentially price the job with higher quality materials or trying to add more where it wasn't needed, we were able to balance paver amount/variation for the pathways and borders so that it made sense both in design and budget. Needless to say, 4 months on, we are still very happy with how it turned out and how everything was done. We started the consultation/design process and contracting in December 2025 and broke ground in March 2026. Stephanie was patient in waiting for other projects to be completed since I also had to replace a roof, install new gutters, and repaint the whole house. By April 2026, the entire backyard looked as designed and blew my family away! Our friend and family complimented on how well everything was done and what a transformation it was. We actually enjoy the backyard a lot more now and so do our children. The pavers have held up very well thus far and most of all, it's safe for anyone to walk on. No sharp edges on the step-down that was installed, no tripping hazards, and no danger of water sitting and pooling in any one area. The rocks along the pathways complement the pavers and do well to keep costs low in the side yard as no one really hangs out on the sides anyway. Extremely happy with Black Diamond, Stephanie, and Raul! Thank you so much; looking forward to getting the front yard and driveway tackled soon!

I recently hired them for a complex project that required a massive range of site work: including demolition, excavation, earthworks, underground utilities, and final concrete work... and ADL engineering knocked it out of the park. Finding a team that can seamlessly transition from heavy earthmoving and utility installation to high-quality, precise concrete finishing is rare, but these guys do it all flawlessly.
