A great place to find slab remnants. I needed some small pieces for my shower and They were able to rush my order due to some schedule issues with my contractor. Very happy with how everything turned out!

United Marble’s experience in this business is unmatched. Their willingness to work with you to arrive at what you would be satisfied in the long run is unparalleled. I visited many showrooms looking for someone willing to work with me on my color, texture, timeline, and budget limitations. Made an appointment first time around. Also was able to visit their graveyard of remnants that offered so many possibilities for creative projects. During my first visit I met Shawn. Shawn is super knowledgeable on all related products. He is very detailed, thoughtful, clear and thorough once you start communicating with him via email. On my second visit I was fortunate to meet Shawn’s mom, who also works there. Her wisdom and extensive experience in the business, I would say had me change my mind to make wise choices and I am very grateful for that. No, she was not upselling anything. Just sharing her wealth of knowledge. United Marble did countertops for our laundry, bathrooms, kitchen and a custom tabletop for the kitchen. Later they returned to enlarge a hole drilled for a faucet because we changed the faucet. I would rate their work top notch, neat, experienced. Crew sent for the installation is highly skilled and respectful of others and of each other.

Our residential design-build firm uses United Marble & Granite for countertop material and fabrication for our kitchen and bath remodels. Their in-depth understanding of the characteristics, durability, and maintenance requirements of various countertop materials enables our clients and designers to make informed decisions. When issues arise (as they often do in remodeling), United Marble is always quick to respond and work toward a solution. They have a great remnant yard for smaller projects that don't require a full slab. Highly recommend!

Very happy with all the work United Marble and Granite performed in our condo. We were a bit of a pain and had them come back twice to explain some issues we didn’t understand and to cut some outlet holes a bit larger. Very responsive and professional. Very pleased with every aspect and the kitchen came out perfect!

The owners of this company are terrible. Paid up front for custom quartz countertops snd demolition for our kitchen remodel. 2 guys came to demo. 3 months later, UMG had still not installed the counters and then quit the job. My family had No sink, no kitchen, know dishwasher for 3 months during the pandemic. Thankfully we demanded refund thru Home Depot. I’m so glad we did. Talking with the arrogant owner on was impossible and I am confident he’d had have tried to keep our money. We found a new countertop installer who finished the job in a week

United Marble and Granite was terrible. Took over 6 weeks for granite countertops. I was told 2. They kept giving different excuses, guys were sick, granite had a crack, they lost my phone number. Then had the nerve to charge me $700 more. I wish we had never used this company. The granite is already stained and they will not return my calls

Paul from Kitchen Reface Depot recommended I work with United Marble & Granite for the counter tops in my Kitchen and Bath. I worked with Frank Russel there. Since I was looking to put granite in for a rental property I just needed a simple black granite in the kitchen and white marble in bath. It was great working with them especially since I'm in a totally different state compared to where the UMG job is located.

I have so many good things to say about my experience at United Marbel and Granite. From the initial visit, setting up the installation, and the amazing follow-through I cannot recommend them enough! They are seriously experts at what they do and it shows. They transformed my kitchen so beautifully and almost to a point where it is unrecognizable. Would use them again for any future projects!

United marble & granite were contracted through Home Depot. We were told that they were able to install one complete countertop for our bathroom which was Home Depot's misinformation. When UMG wanted to come out one week earlier than they were scheduled, I informed them I was working. I had other people onsite working on my bathroom so they decided to come out and measure when I wasn't present. I received a call from them when they were in my home and that was when I was informed that the counter would be two separate pieces and there would be a seam. It also would not come with an edge, that would be extra, also something I was not informed of. The person measuring also told me he had to take my sink or the template for the sink, I told him I had an identical sink by the front door with template, but he chose to take my sink. After giving it a little of thought, we decided not go with them as installers. I did not get a good feeling from them after talking to Sean. His solution for hiding a seam in his home was to put a microwave on top of it, I was like we're installing these counters in my bathroom, how does that make any sense??? I didn't get the vibe he was into customer service, just matter of fact but certainly not helpful. Really glad I trusted my gut, because we canceled the install with them and still had to pay a $200 trip charge. I had to initiate contact with them about getting my sink returned and spoke to Ana. She told me to pick up my sink in Santa Clara, what??? They took my property out of my home, but refused to return it. I was told they do not do drop offs. This was the same response from Sean as well, they were both unwilling to do the right thing and return my sink to my home and were close to hostile regarding the situation. The only compromise they were willing to make was to send it with their installers the next time they were in the area and I would have to go to the place they were doing the job to pick it up. I would never wish this type of service upon anyone!!! I am hoping that Home Depot does not use them in the future for installs, I certainly won't be going back to either. Good luck future customers, I really hope you don't have the same poor service and experience as I did!

We were looking for a slab for our bathroom remodel and met "Ana" at United Marble and Granite. She is very knowledgeable and extremely helpful walking us through all the types of suitable stone products for our project. She patiently explained and educate us on natural and man-made slab characteristics. Thank you Ana, you were a great help and we enjoyed working with you! Rich & Sharon B.

I am thrilled with my countertops and cannot say enough about the excellent service I received at United Granite and Marble. From the initial consultation I learned so much from both Velma and Sean. They were patient and answered my numerous questions. They are extremely knowledgeable in all aspects from design to installation. The person (forgot his name) who came to take measurements was quite helpful and explained the next steps in the process. The installation was quick and efficient. They took care to cover my floors and cabinets to protect them from damage. I highly recommend UMG!

We recently renovated our kitchen. We needed new countertops and contacted three companies. Ultimately, we landed on UMG. What led us to this decision was UMG's attention to our needs, service, and a willingness to provide us with the countertop solution to our renovation. Our next project is our master bathroom. We will be going back to UMG

I would highly recommend United Marble! From my 1st phone call to set up a walk through their scrapyard to pick out some marble, through to completion of the project, they were super responsive, detailed, and on time. They spent a lot of time making sure that they understood exactly what I wanted and reviewed the Specs with pictures and measurements multiple times. I ended up with pieces that I am absolutely in love with!!

I have been looking for a new top for my vanity for month. Given the supply shortages this was a difficult task. I found a perfect slab in their yard - they have a very good selection! The work they did was excellent and the install went without any issues. I fully recommend them!

Best service. Most thoughtful. Completely professional. We needed to recover any remaining product when we made a design change late in the game for our kitchen. Frank drove me around the yard to find our remnant. Then we realized the seam would be in a completely wrong place on one segment. They took a look at what we needed and updated our job with no problem and gave us a key design recommendation that vastly improved the look of our kitchen. (Note, while that won't always happen, it was the attention they gave to work through the issue that mattered most.) The installation itself went smoothly and everything looks amazing. We recommend United Marble and Granite for any of your needs!!
