Ron G and his on-site team lead by Omero did a great job! Ron communicated with me on each step of the process. I happened to be out of town on vacation while the entire project was completed. Ron kept me informed with extensive photos and timing. It was fantastic coming home to the finished product. It turned out even better than I imagined, and even several neighbors are commenting on how beautiful it turned out. Thank you, Ron and Black Diamond Pavers!
I've had the opportunity to work with Ron in a handful of lighting and audio projects. He's an absolute professional, and embraces learning something new every time! Ron is incredibly detailed in his work, ensuring everything is perfect, which I admire greatly. I can genuinely say that Ron cares about the work and everyone involved. He goes above and beyond, making every project enjoyable and successful. ?? It's a genuine pleasure collaborating with someone so dedicated and passionate. Look forward to tackling our next lighting project together!
As a Lake Forest homeowner with a 50-year-old residence, I desired to restore the circa 70’s look that would complement that esthetic. Meeting Ron G. and having him listen to blending the original with the new and offering suggestions made this an easy choice! Ron G. is exceptional in his knowledge and personal professionalism. Several options were offered, including a variety of schematics for each. Clearly, above expectations in time and effort. Ron G. walked through each option clearly listening to my vision and brought a higher value to the plan decided upon, still working well within budget. Ron G. won this contract, no question! I obtained several bids from contractors who didn’t listen or provide standard project services without up-charges. Our project came in under budget and installation was quiet and quick; and the results speak for themselves. Now, planning on a phase II project with Ron G. You don’t let a great guy like this go!
This is our second time hiring Black Diamond—after they crushed it on our front yard, we brought them back for the backyard, and they did not disappoint.We started with a mess: overgrown trees, broken furniture, and leftover construction junk. They completely transformed it—removed everything, replaced our old cracked brick wall with a new fence (even coordinated with all the neighbors), and swapped out the concrete and lawn for beautiful pavers and fresh grass.They also built us an awesome BBQ area with a gas line, sink, power, raised seating—the works. Even added an outdoor audio system.Ron was our project manager both times and he’s the reason we keep coming back. Super organized, great communication, and just on top of everything. We’ve recommended Black Diamond to friends and will keep doing it—they’re that good.
