He told me what to expect from start to finish. I also needed trees trimmed, a stump removed and rubbish hauled away and his team completed that as well. This project was delayed and he was so patient. I could go on and on but the photos speak for themselves. In addition to all that, he is a kind person and so easy to work with. I am a happy customer 100%.

We got a recommendation from multiple neighbors to call Humberto at Cuevas Concrete to do a couple…read moreof jobs for us here in Trilogy in Rio Vista and I have to say that Humberto is the AWESOME! His work is not only beautiful but is reasonably priced. He comes on time and cleans up after each day that he works! I highly recommend him. He does everything from slabs, foundations, retaining walls, driveways and sidewalks. His work is actually better than our home builders work.

I HIGHLY recommend Humberto Cuevas for your concrete work! He is amazing, and a very meticulous,…read morehard worker. He lays forms with perfect skill, and he and his wife hand-tie rebar before he brings in his experienced help on pour day. He has excellent work ethics, does what he says on schedule, and wears a mask--even though they are working outdoors. This is the first time I've ever had stained & stamped concrete done, and I absolutely love it!

Thomas' company was ready and able and gave us a competitive price. On the day we scheduled the job his team showed up early (which made my day), and more importantly, the crew laid down the surface texture the artist requested to ensure the chalk art was visually optimized. Terrific company, I highly recommend.

My front yard needed help desperately. I am super glad I chose Black Diamond to handle my project…read more My point of contact Matthew was super professional and gave me expert advice every step of the way. I really appreciated that he was always available to answer my questions. Matthew also went out of his way to ensure the materials we liked were acquired for the project. He ensured that everything was to our liking and was meticulous in his walk-throughs and made sure everything was completed perfectly. Leo and his team worked super hard and diligently. He paid close attention to detail and didn't rush any part of the remodel. During demolition he was super careful not to damage my property and always asked for our opinion/permission before installing or completing a part of the remodel. Overall I have more projects in mind for my house and will be enlisting Matthew and his team in the future. My wife and I are super happy with our new landscape. Thank you Matthew and Leo!

Black Diamond Paver Stones & Landscape, Inc. did work for us six years ago to our walkway entrance…read moreof our home. What initially sold us was the 26 year warranty. So, we decided to reach out to them since we loved the pavers they did already, but this time with a MUCH bigger job. They sent Matt M. to our home, who ended up being our Project Manager. What was super important to us was to find someone that could translate our vision to his team and bring it to life. This is exactly what Matt did. His crew Sergio Sr, Sergio Jr and Marco and the rest of the crew were absolutely amazing! They paid attention to detail. They never rushed the process. They were always kind and understanding. They worked endless hours in brutal weather and poured love into our home. Super humans is what we called them! Master Masonry at its finest. If you are ever thinking about any hardscaping, landscaping or draining system for your home it would be in your best interest to reach out to Black Diamond. And ask for Matt and his All Star Team. They will not disappoint. Thank you Black Diamond!

Had this company seal cracks and put slurry on large driveway in Pleasant Hill. Very disappointed…read morewith the job. Many small cracks remained unsealed and seal coating was extremely thin resulting in underlining marks and seals showing through like a road map. Looked pretty bad and the owner did not even ask me to check out the job when they finished. Just sent a worker for the payment and left. I had to go to local Home Depot and buy several additional cans of seal and spread it myself in order to get the driveway surface to look decent. Buyer beware with this company!!

I'm giving these guys a perfect review in part to counteract the single very negative review here…read more My neighbor and I share a long, steep driveway here in Montclair, Oakland. North-Cal first gave us a fair estimate on the job that was very detailed and clear on the process (unlike other bids). These guys worked long and hard to do the job right. They started at 8am with a crew of 5-7 and worked a 12-hour day to finish it up right. They took their lunch breaks in shifts to keep the job rolling. Paving is a multi-step process and they kept returning to problem areas to soften the asphalt and smooth it out until it was perfect. Unfortunately their spreader broke down near the bottom of the driveway but that didn't stop them! They completed the last few feet BY HAND, well after dark. They could have bailed and said "good enough", but that's clearly not how this company rolls! Highly recommend.

Fast forward almost two years later, it has gotten worse. I'm very disappointed as we were very nice and accommodating with them and even provided food and beverages while it was hot outside. We got a few different quotes and they were all within the same price range but with the good reviews this team had I thought it was the best choice. WRONG! They also said they can come back and re pour an also to fix a couple other things and we followed up twice and they never showed up. I feel like we were robbed and have decided to consider seeking legal advice on how to go about this. I'll update with more pictures soon. Don't give them your business! I'll be updating with new pictures to see how bad it is.
