    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 live in Monterey and discovered Black Diamond because I really liked what they did with one of my…read moreneighbor's front area.  It pays to leave your sign out! Frances was my project manager and on the first visit I described my vision and let her know I wanted to do some of the work myself because I had a limited budget.  She was very accommodating about that and drew up plans based on what I wanted help with.  She actually did a few iterations as we talked through design and my changes after I saw the plans.  She helped with design and material suggestions but also drainage suggestions that helped me feel confident I wouldn't have problems down the line.  Black Diamond did all the hardscape of pavers and prepped and installed my lawn.  I did everything else in the pictures. I purchased all the plants, but Frances was helpful in giving me ideas about what grew best in my area which doesn't get a lot of sun.  They are a bit pricey but I was willing to pay more because they gave me the confidence that they would do the work correctly.  And Frances was amazing to work with! It came out beautiful!  Their workers were not very friendly and didn't speak much English but they knew their business and Frances visited often to oversee the work.   There were lots of little decisions to be made and Frances was patient with me as I took time to decide on some things.  They also put in piping so I could run more irrigation, if needed and electrical wiring.  They also ran pipe for my propane tank hose so it would be underground.  My only frustration is that they didn't put string through or something that would help pull the wiring or hose through more easily.  A simple thing that would have really helped.  Overall, I am very satisfied and would recommend them.  They are pricey and their contract is pretty one-sided, but because everything went well, that wasn't a problem. Apologies for the pictures in random order.  Just a side note--I also used Black Diamond for my rental in Southern California and the project manager did a great job there too.

    We used Coast Building Products to install a Fireplace Insert. Sales did a great job. Install…read morewent well. Shortly after we had challenges with the ignitor. Each time a service call was made (3 times), they said it was fine. And it wasn't until the 4th call that they experienced what we had and FINALLY ordered the part after much delay and replaced it. So much for believing your customer. Next up was the handle slipping off, the stove isn't that old so we called again and instead of making a call, they ordered a part. Another delay and multiple calls, no answer on when it might arrive. 2 MONTHS later we got lucky and someone actually answered the phone saying the order was lost in a move and it would be reordered. ANOTHER MONTH and we insisted on a call vs part in case it could be repaired. It took the tech 15 minutes to repair the handle with a Phillips screwdriver, the tech showed us the "hidden" access to repair it in case it happened again. After all the delays and unanswered calls, our handle was fixed to the tune of a $350 for a 15 min. service call! We paid the tech because he wasn't responsible for the invoice. We called to ask about the charge and but Saul Andrade didn't answer the phone as usual. He did call back a few days later left a curt message to say there was nothing he could so about it. What a waste of time and money working with this company. Also note that they've now moved to Santa Clara. So, watch out Bay Area.

And the rescheduled to the 3rd with out letting me know. Ok that's fine, couple days what ever. We'll irs the 3rd and the installer arrived, took one look and said he can't do the install due to the shape of the chimney. What's the point of doing a pre install inspection? I was told it would be no problem. What a waste of time
